UNITED STATES DISTRICT COURT
SOUTHERN DISTRICT OF NEW YORK
ELIZABETH MANUEL and VIVIEN GROSSMAN, on
behalf of themselves, all others similarly situated, and the
17 Civ. 7955 (PAE)
OPINION & ORDER
PAUL A. ENGELMAYER, District Judge:
This case involves a challenge to the use of the word “diet” in connection with the
ubiquitous soft drink Diet Pepsi. Plaintiffs Elizabeth Manuel and Vivien Grossman bring this
putative class action against defendant Pepsi-Cola Company (“PepsiCo”) alleging unfair and
deceptive business practices, false advertising, fraud, negligent misrepresentation, and breaches
of express and implied warranties, all arising under New York law and all based—in whole or
part—on PepsiCo’s use of the “diet” adjective to describe this beverage.
Now pending is PepsiCo’s motion to dismiss plaintiffs’ First Amended Complaint under
Federal Rule of Civil Procedure 12(b)(6). See Dkt. 27. For the following reasons, the Court
grants PepsiCo’s motion and dismisses the complaint in its entirety.
Factual Background 1
The facts related herein are drawn primarily from the First Amended Complaint. Dkt. 24
(“FAC”). For the purpose of resolving the motion to dismiss, the Court assumes all well-pled
facts to be true, drawing all reasonable inferences in plaintiffs’ favor. See Koch v. Christie’s
Int’l PLC, 699 F.3d 141, 145 (2d Cir. 2012). The Court has also considered the scientific articles
and studies incorporated into the FAC by reference. See Chambers v. Time Warner, Inc., 282
F.3d 147, 152–53 (2d Cir. 2002). Further, the Court has taken notice of a matter of common
knowledge absent from the FAC, but uncontroverted in plaintiffs’ opposition brief: that in
In 1964, PepsiCo introduced Diet Pepsi. FAC ¶ 12. Unlike Pepsi, which contains sugar,
Diet Pepsi contains no calories. Id. ¶ 15. Instead, Diet Pepsi is sweetened with the non-nutritive
sweeteners (“NNS”) aspartame acesulfame-potassium and sucralose. Id. ¶ 1. PepsiCo uses the
term “diet” in marketing Diet Pepsi to signal the use of NNS in place of sugar. Id. ¶ 15.
Plaintiffs allege that as a result of PepsiCo’s use of the term “diet” in marketing Diet
Pepsi, “consumers reasonably believe that the product will assist in weight loss, or at least
healthy weight management, for example, by not causing weight gain.” Id. ¶ 16. This belief is
misplaced, plaintiffs allege, because “[s]cientific evidence demonstrates [that] nonnutritive
sweeteners like aspartame acesulfame-potassium and sucralose interfere with the body’s ability
to properly metabolize calories, leading to weight gain and increased risk of metabolic disease,
diabetes, and cardiovascular disease.” Id. ¶ 2.
Plaintiffs are long-time purchasers and consumers of Diet Pepsi. Id. ¶¶ 53–56. They
have also struggled with obesity for many years. Id. ¶¶ 54, 56. Absent PepsiCo’s false and
misleading labeling, they allege, they would not have purchased Diet Pepsi at the price they paid.
Id. ¶ 57.
On October 16, 2017, plaintiffs filed the complaint in this action. Dkt. 1. On December
12, 2017, PepsiCo filed a motion to dismiss. Dkt. 17. On December 13, 2017, the Court issued
an amend-or-oppose order, directing plaintiffs, by January 9, 2018, to file either an amended
complaint or a brief in opposition to the motion to dismiss. Dkt. 19.
addition to Diet Pepsi, PepsiCo also markets Pepsi, a soft drink containing sugar. See Heckman
v. Town of Hempstead, 568 F. App’x 41, 43 (2d Cir. 2014) (on motion to dismiss, court may
consider “facts of which judicial notice may properly be taken under Rule 201 of the Federal
Rules of Evidence”); see also Fed. R. Evid. 201 (“generally known” facts subject to judicial
On January 2, 2018, plaintiffs filed the FAC. Dkt. 24. On January 19, 2018, PepsiCo
renewed its motion to dismiss. Dkt. 27 (“Mem.”). On January 31, 2018, plaintiffs filed a
memorandum of law in opposition, Dkt. 30 (“Opp.”), as well as a declaration in support, Dkt. 31
(“Melamed Decl.”). On February 7, 2018, PepsiCo filed its reply. Dkt. 33 (“Reply”).
Since February, the parties have filed three letters alerting the Court to decisions in
First, on March 5, 2018, PepsiCo notified the Court of a recent decision by Judge
William Alsup of the Northern District of California. See Dkt. 39 (Becerra v. Coca-Cola Co.,
No. C 17-5916 (WHA), 2018 WL 1070823 (N.D. Cal. Feb. 27, 2018) (“Coca-Cola”), appeal
Second, on April 2, 2018, plaintiffs notified the Court of a recent decision by Judge
William H. Orrick, also of the Northern District of California. See Dkt. 41 (Becerra v. Dr
Pepper / Seven Up, Inc., No. 17-cv-5921 (WHO), 2018 WL 1569697 (N.D. Cal. Mar. 30, 2018)
And third, on April 19, 2018, PepsiCo notified the Court of a recent decision by Judge
George B. Daniels of the Southern District of New York. See Dkt. 43 (Excevarria v. Dr. Pepper
Snapple Grp., No. 17-cv-7957 (GBD), ECF No. 54 (S.D.N.Y. Apr. 18, 2018) (“Excevarria”)).
Each of these decisions dismissed claims substantively identical to those here. Each did
so on essentially the same grounds: that although state-law claims alleging false or misleading
use of the word “diet” in soft drink labeling are not preempted by federal law, the plaintiffs there
had failed to allege plausibly that reasonable consumers were likely to be deceived by use of the
“diet” term. See Coca-Cola, 2018 WL 1070823, at *1–4; Dr Pepper, 2018 WL 1569697, at *3–
6; Excevarria, No. 17-cv-7957 (GBD), ECF No. 56 at 80–84. Judges Alsup and Orrick went a
step further. Each held that the scientific studies relied on by plaintiffs failed to supply a causal
link between diet soft drink consumption and weight gain, as would be necessary to sustain their
claims. See Coca-Cola, 2018 WL 1070823, at *4; Dr Pepper, 2018 WL 1569697, at *6–7.
Applicable Legal Standards
To survive a motion to dismiss under Rule 12(b)(6), a complaint must plead “enough
facts to state a claim to relief that is plausible on its face.” Bell Atl. Corp. v. Twombly, 550 U.S.
544, 570 (2007). A claim will only have “facial plausibility when the plaintiff pleads factual
content that allows the court to draw the reasonable inference that the defendant is liable for the
misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). A complaint is properly
dismissed where, as a matter of law, “the allegations in a complaint, however true, could not
raise a claim of entitlement to relief.” Twombly, 550 U.S. at 558.
For the purpose of resolving a motion to dismiss, the Court must assume all well-pleaded
facts to be true, drawing all reasonable inferences in favor of the plaintiff. See Koch, 699 F.3d at
145. That tenet, however, “is inapplicable to legal conclusions.” Iqbal, 556 U.S. at 678. A
pleading that offers only “labels and conclusions” or “a formulaic recitation of the elements of a
cause of action will not do.” Twombly, 550 U.S. at 555.
Defendants move to dismiss the FAC on four grounds: that (1) plaintiffs’ claims, all
arising under New York law, are preempted by federal law; (2) plaintiffs’ claims should be
dismissed or stayed pursuant to the primary jurisdiction doctrine; (3) plaintiffs have failed to
plead actual deception; and (4) plaintiffs’ false advertising claim fails to allege causation. The
Court addresses each in turn.
In determining whether state-law claims are preempted by federal law, courts look first to
congressional intent. 23-34 94th St. Grocery Corp. v. N.Y.C. Bd. of Health, 685 F.3d 174, 180–
81 (2d Cir. 2012) (citing Cipollone v. Liggett Grp., Inc., 505 U.S. 504, 516 (1992)). Congress
may manifest its intent “explicitly, through the express language of a federal statute, or
implicitly, through the scope, structure, and purpose of the federal law.” N.Y. SMSA Ltd. P’ship
v. Town of Clarkstown, 612 F.3d 97, 104 (2d Cir. 2010).
Where Congress has codified its preemptive intent in statutory form, the court’s analysis
properly begins with the language of the statute. 23-34 94th St. at 181. But even where a federal
law contains an express preemption clause, a court may still be required to consider implied
preemption as it looks to the “substance and scope of Congress’ displacement of state law.”
Altria Grp., Inc. v. Good, 555 U.S. 70, 76 (2008). To that end, Congress’s preemptive intent
may be inferred where an actual conflict exists between state and federal law. Id. at 76–77.
Nevertheless, “because the States are independent sovereigns in our federal system,
[courts] have long presumed that Congress does not cavalierly pre-empt state-law causes of
action.” Medtronic, Inc. v. Lohr, 518 U.S. 470, 485 (1996). Accordingly, where there are
plausible alternative readings of a preemption provision, courts “have a duty to accept the
reading that disfavors pre-emption.” Bates v. Dow Agrosciences LLC, 544 U.S. 431, 449 (2005).
Because the preemption inquiry turns first on Congress’s intent as manifested by statute,
the Court begins with an overview of the federal soft-drink labeling regime. The Court then
addresses whether that body of law preempts plaintiffs’ claims. For the reasons that follow, the
Court holds that federal law does not bar plaintiffs from pursuing, under state law, consumerprotection claims alleging that marketing a soft drink as “Diet” Pepsi is false or misleading.
The Federal Labeling Regime
In 1990, Congress amended the United States Federal Food, Drug, and Cosmetic Act
(“FDCA”) with the Nutrition Labeling and Education Act (“NLEA”). The NLEA specifically
addresses use of the term “diet” in soft drink labeling. It excludes from certain labeling
requirements (and thereby authorizes) use of the term “diet” on a soft drink label where: “(i) such
claim is contained in the brand name of such soft drink, (ii) such brand name was in use on such
soft drink before October 25, 1989, and (iii) the use of the term ‘diet’ was in conformity with [21
C.F.R. § 105.66].” 21 U.S.C. § 343(r)(2)(D). At the time, 21 C.F.R. § 105.66 provided that soft
drinks could be labeled “diet” if their calorie count fell below certain thresholds. See 21 C.F.R.
§ 105.66 (1989). There is no dispute that Diet Pepsi met those requirements, and that it does so
to this day. See FAC ¶ 15.
21 U.S.C. § 343(r)(2)(D) also provides that use of the term “diet” “is subject to” 21
U.S.C. § 343(a). As relevant here, that FDCA provision—section 343(a)—prohibits labeling
that is “false or misleading in any particular.” Id. § 343(a).
Finally, the NLEA includes an express preemption provision. See Id. § 343-1. As
relevant here, it prohibits state or local governments from imposing “any requirement respecting
any claim . . . made in the label or labeling of food that is not identical to the requirement of
section 343(r)”—i.e., the provision addressing nutrition- and health-related label claims, of
which § 343(r)(2)(D) is a subsection. Id. § 343-1(a)(5). Significant here, the NLEA’s
preemption provision does not apply to § 343(a), the FDCA’s prohibition on false or misleading
In 1993, following passage of the NLEA, the FDA issued a new implementing regulation
tracking the language of § 343(r)(2)(D): “A soft drink that used the term diet as part of its brand
name before October 25, 1989, and whose use of that term was in compliance with § 105.66 of
this chapter as that regulation appeared . . . on that date, may continue to use that term as part of
its brand name, provided that its use of the term is not false or misleading under [21 U.S.C.
§ 343(a)].” 21 C.F.R. § 101.13(q)(2).
In 1990, Congress authorized the continued use of the term “diet” by then-compliant soft
drinks, with the caveat that such use would remain authorized so long as it was not false or
misleading. See 21 U.S.C. § 343(r)(2)(D). There is no indication that upon enactment of the
NLEA, Congress viewed legacy soft drinks’ use of the term “diet” as false or misleading. See
Opp. at 8 n.1. Likewise, the FDA has not only authorized continued use of the term “diet,” but
has also indicated that it was unaware of any planned line extensions that would not conform
with 21 C.F.R. § 105.66. See Food Labeling: Nutrient Content Claims, General Principles,
Petitions, Definition of Terms; Definitions of Nutrient Content Claims for the Fat, Fatty Acid,
and Cholesterol Content of Food, 58 Fed. Reg. 2,302, 2,313 (Jan. 6, 1993). 2
Accordingly, a plaintiff challenging a legacy soft drink’s use of the term “diet” as false or
misleading faces a significant obstacle. Congress and the FDA determined, to the extent of the
information available to them in 1990 and 1993 respectively, that the nutrient content claim
“diet,” standing alone, was not false or misleading as applied to then-compliant soft drinks
containing NNS. It follows that a claim challenging such use of the term, if based solely on
information available to Congress and the FDA before 1993, is preempted. Whether viewed as a
matter of express preemption under § 343-1(a)(5), or as implied preemption on the theory that a
The FDA has also not voiced concern about the effects of NNS on weight management. On the
contrary, it has expressly authorized use of NNS in foods purporting to be “useful in reducing
or maintaining body weight.” See 21 C.F.R. § 105.66(a), (b), (e).
challenge based on the identical information before Congress and the FDA necessarily conflicts
with their considered judgment, such claims, without more, cannot support liability. See Red v.
The Kroger Co., No. 10-cv-1025 DMG (MANx), 2010 WL 4262037, at *5 (C.D. Cal. Sept. 2,
2010) (a nutrient content claim that is expressly permitted under federal law cannot be false or
This challenge, however, is different. Plaintiffs here claim that developments after the
early 1990s—specifically, PepsiCo’s marketing campaigns and the current state of scientific
knowledge—today make PepsiCo’s use of the term “diet” false or misleading.
For the reasons that follow, a claim to that effect—whatever its merit—is not preempted.
In 1990 and 1993, respectively, Congress and the FDA authorized continued use of the
term “diet” only provisionally. Section 343(r)(2)(D) subjects legacy soft drinks’ use of the word
“diet” to § 343(a), which prohibits false or misleading labeling. And § 343(a), unlike § 343(r),
has no preemptive force. See 21 U.S.C. § 343-1; see also Dr Pepper, 2018 WL 1569697, at *4;
Coca-Cola, 2018 WL 1070823, at *2–3.
PepsiCo responds that this argument misreads § 343(r)(2)(D). That provision, PepsiCo
explains, merely exempts diet soft drinks from the labeling requirements of § 343(r)(2)—not
from § 343(r) altogether. See 21 U.S.C. § 343(r)(2)(D) (excluding diet soft drinks from
“[s]ubparagraph (2)”). Accordingly, PepsiCo argues, use of the word “diet” on soft drink labels
remains subject to § 343(r) as a nutrient content claim, and therefore remains subject to § 343-1’s
preemptive force. See Mem. at 10–11; Reply at 6–7.
Although perhaps a technically accurate description of the statutory structure, this
argument ultimately does not achieve the preemption that PepsiCo seeks here. That is because
the NLEA’s preemption provision preempts only those state-law requirements “not identical to
the requirement of section 343(r).” 21 U.S.C. § 343-1(a)(5). And § 343(r) itself incorporates
§ 343(a), which prohibits false or misleading labeling. Thus, where a plaintiff brings claims
against PepsiCo for its use of the word “diet” under state laws that prohibit false or misleading
labeling, those claims, tracking as they do the standard set in § 343(a), are not preempted. See
Drake v. Lab. Corp. of Am. Holdings, 458 F.3d 48, 64 (2d Cir. 2006) (“[T]he federal
government’s intent to preempt substantive state-law standards does not necessarily imply an
intent to preempt state-law remedies for violations of federal standards.”).
PepsiCo responds that the state consumer protection laws invoked here—purportedly
targeted at false or misleading statements, see infra Part III.C—are nevertheless preempted
because they would impose broader obligations on PepsiCo than those required by § 343(a). See
Mem. 11–12; see also In re PepsiCo, Inc. Bottled Water Mktg. and Sales Practices Litig., 588 F.
Supp. 2d 527, 534 (S.D.N.Y. 2008) (state-law claims are preempted if they “impose a broader
obligation than federal law” (quoting Bates, 544 U.S. at 453)). In PepsiCo’s view, § 343(a), as
incorporated by § 343(r)(2)(D), provides a remedy only against the surreptitious introduction of
high-calorie sweeteners into legacy “diet” soft drinks. See Mem. at 6–7. PepsiCo thus reads this
section, in the context of challenges to the use of the word “diet” to describe a legacy soft drink,
to prohibit only false or misleading statements as to the drink’s calorie content.
In support, PepsiCo points first to the FDA’s statement that it would regard a label as
false and misleading if it falsely stated that a food was a formulated meal replacement, so as to
avoid the calorie content requirements associated with the term “diet.” See Food Labeling: Label
Statements on Foods for Special Dietary Use, 58 Fed. Reg. 2,427, 2,428 (Jan. 6, 1993). PepsiCo
reads this example to mean that “diet” binds a soda manufacturer only as to calorie content. But
while the term “diet” surely implies calorie content restrictions, it does not follow that the only
form of cognizable misstatements with respect to a “diet” label are those as to calorie content.
The statute is not fairly read to make a misstatement as to calorie content a necessary—as
opposed to sufficient—condition for liability under § 343(a) and (r)(2)(D).
PepsiCo next argues that, because the federal labeling regime has expressly authorized
use of the term “diet” in reduced-calorie products, any state regulation that could be implied to
make use of that term a basis for liability is necessarily inconsistent with—and preempted by—
federal law. See Mem. at 12. But as explained above, the statute has authorized use of the term
“diet” only provisionally, even for soft drinks like Diet Pepsi that are grandfathered under
§ 343(r)(2)(D). Congress there has prohibited any false or misleading use of the term “diet,”
even on grandfathered drinks. Whatever the likelihood or unlikelihood of such a scenario, it
follows that, if future science or other circumstances were to support a claim that that term was
now false or misleading as applied to soft drinks sweetened with NNS, the prohibition on false
and misleading labels in the federal labeling regime would then be triggered, and any identical
state-law claims would not be preempted.
In any event, PepsiCo’s narrow reading of “false or misleading,” which would preempt
state-law claims other than those alleging an inaccurate calorie count, fails as a matter of
statutory and regulatory construction. It is contrary to the text of § 343(a), which broadly
prohibits statements that are false or misleading “in any way”—not just statements that mislead
in relation to other requirements of the FDCA. It is also inconsistent with 21 C.F.R.
§ 105.66(e)(1), which, for soft drinks marketed after October 25, 1989, see 21 C.F.R.
§ 101.13(q)(2), requires both that the term “diet” not be false or misleading, and that the label
contain a “comparative calorie claim” in compliance with the calorie content requirements of 21
C.F.R. § 101.60. The regulations for post-1989 diet soft drinks thus treat “false and misleading”
as a separate requirement from calorie content requirements. On PepsiCo’s view of preemption,
therefore, the term “false and misleading” would have different meanings as applied to soft
drinks marketed before and after 1989, allowing manufacturers of the former but not the latter to
engage in false and misleading labeling other than as to calorie content. There is no basis to
assign to Congress such an intent. See Gustafson v. Alloyd Co., 513 U.S. 561, 569 (1995) (in a
“symmetrical and coherent regulatory scheme,” “operative words have a consistent meaning
Thus, whatever its merits, plaintiffs’ claim that changed circumstances today make
PepsiCo’s use of the term “diet” false and misleading so as to violate state law is not preempted.
The Court therefore turns to PepsiCo’s other arguments.
PepsiCo next contends that this Court should dismiss or stay this case pursuant to the
primary jurisdiction doctrine.
“Despite its name, the doctrine is not jurisdictional.” Canale v. Colgate-Palmolive Co.,
258 F. Supp. 3d 312, 324 (S.D.N.Y. 2017). Rather, “[t]he doctrine of primary jurisdiction is
concerned with ‘promoting proper relationships between the courts and administrative agencies
charged with particular regulatory duties.’” Ellis v. Tribune Television Co., 443 F.3d 71, 81 (2d
Cir. 2006) (quoting United States v. W. Pac. R.R. Co., 352 U.S. 59, 63 (1956)). Its “central aim
is to allocate initial decisionmaking responsibility between courts and agencies and to ensure that
they do not work at cross-purposes.” Id. (quotation marks omitted).
As such, the doctrine has a “relatively narrow scope,” Goya Foods, Inc. v. Tropicana
Prods., Inc., 846 F.2d 848, 851 (2d Cir. 1988), and “should generally be reserved for resolution
of an issue of first impression, or a particularly complicated issue that Congress has committed to
a regulatory agency,” King v. Time Warner Cable, 113 F. Supp. 3d 718, 724 (S.D.N.Y. 2015)
(quotation marks omitted). Although there is no bright-line test, this Circuit applies a “case-bycase” analysis mindful of four factors: “(1) whether the question at issue is within the
conventional experience of judges or whether it involves technical or policy considerations
within the agency’s particular field of expertise; (2) whether the question at issue is particularly
within the agency’s discretion; (3) whether there exists a substantial danger of inconsistent
rulings; and (4) whether a prior application to the agency has been made.” Ellis, 443 F.3d at 82–
As to the first factor, it is true that a scientific question underlies this dispute: the
nutritional impact of artificial sweeteners. But at bottom, this case is “far less about science than
[it is] about whether a label is misleading, and the reasonable-consumer inquiry upon which . . .
the claims . . . depend is one to which courts are eminently well suited, even well versed.” In
re Kind LLC “Healthy and All Natural” Litig., 209 F. Supp. 3d 689, 694–95 (S.D.N.Y. 2016)
(quoting In re Frito-Lay N. Am., Inc. All Nat. Litig., No. 12-MD-2413 (RLM), 2013 WL
4647512, at *8 (E.D.N.Y. Aug. 29, 2013)). The Court is therefore “reluctant to declare that
issues of alleged consumer deception are necessarily outside the conventional wisdom of judges
(or even juries).” Id. at 695; see also Ault v. J.M. Smucker Co., No. 13 Civ. 3409 (PAC), 2014
WL 1998235, at *5 (S.D.N.Y May 15, 2014) (same).
The second factor is more equivocal. Congress has authorized the FDA to promulgate
regulations regarding “diet” soft drink labeling. See 21 U.S.C. § 343(r)(2)(D). And because the
FDA may prohibit labels that are “false or misleading in any particular,” the dispute about
PepsiCo’s labels might “seem to be particularly within the FDA’s discretion.” In re KIND
LLC, 209 F. Supp. 3d at 695. These considerations, however, do not carry the day here. In
2015, a group known as Right to Know applied to the FDA to resolve the very issue presented
here. See Melamed Decl. Ex. 13. The agency declined the invitation. See Melamed Decl. Ex. 5
(explaining that requests for enforcement actions are not proper subjects of a citizen petition).
Accordingly, whatever the scope of the FDA’s discretion, every indication is that the FDA will
not exercise that discretion as to the matter at hand.
Similarly, as to the third factor, given that the FDA has declined to take up the question
presented here, there is no danger of inconsistent rulings. The Second Circuit has advised that
“[c]ourts should be especially solicitous in deferring to agencies that are simultaneously
contemplating the same issues.” Ellis, 443 F.3d at 88. But when the “agency is not
simultaneously contemplating the same issue . . . this factor weighs against applying the primary
jurisdiction doctrine.” Goldemberg v. Johnson & Johnson Consumer Cos., 8 F. Supp. 3d 467,
477 (S.D.N.Y. 2014) (citation omitted). PepsiCo notes that several other courts are currently
considering “the use of the term ‘diet’” and therefore fears divergent results in different districts.
See Mem. 15–16. But “decisions from various district and appellate courts regularly conflict.”
Goldemberg, 8 F. Supp. 3d at 477. The potential for such conflict is unavoidable absent action
by the FDA or a resolution by the nation’s highest court.
Finally, for much the same reasons, the fourth factor counsels against dismissing or
staying the case. True, “prior application to the agency”—such as the one submitted by Right to
Know—ordinarily supports application of the primary jurisdiction doctrine. See Ellis, 443 F.3d
at 89. But as noted, the FDA squarely rejected Right to Know’s application. As the Second
Circuit has recognized, “where resort to the agency would plainly be unavailing in light of its
manifest opposition, . . . courts need not bow to the primary jurisdiction of the administrative
body.” Ellis, 443 F.3d at 90 (quoting Bd. of Educ. v. Harris, 622 F.2d 599, 607 (2d Cir. 1979)).
“Similarly, primary jurisdiction is not required when a referral to the agency would significantly
postpone a ruling that a court is otherwise competent to make.” Canale, 258 F. Supp. 3d at 324
(quotation marks omitted). In such circumstances, “[c]ommon sense” dictates that even if the
FDA’s “expertise would be helpful, a court should not invoke primary jurisdiction when the
agency is aware of but has expressed no interest in the subject matter of the litigation.” Id.
(quotation marks omitted). This Court therefore declines to invoke primary jurisdiction here.
The Court turns now to PepsiCo’s argument that plaintiffs’ allegations must be dismissed
for failure to state a claim under Rule 12(b)(6). The Court so holds for two independent reasons:
First, the FAC is based on a strained and artificial interpretation of the phrase “Diet Pepsi” that
no reasonable consumer would adopt. Second, the FAC does not plausibly allege that PepsiCo’s
representations were actually deceptive.
Plaintiffs’ Strained Interpretation of “Diet”
The FAC’s claims under New York law each require establishing a false or misleading
statement. 3 (Indeed, as discussed above, to be within the scope of permissible state regulation
under 21 U.S.C. § 343-1, a plaintiff’s claims must allege a false or misleading representation.)
Under New York law, in the consumer protection context, a statement is deceptive only if
it is likely to mislead a reasonable consumer. See Fink v. Time Warner Cable, 714 F.3d 739, 741
See Bowring v. Sapporo U.S.A., Inc., 234 F. Supp. 3d 386, 390 (E.D.N.Y. 2017) (“To assert a
claim under either [New York General Business Law §§ 349 or 350], a plaintiff must establish

that a court may determine as a matter of law that an allegedly deceptive advertisement would
not have misled a reasonable consumer.” Fink, 714 F.3d 739 at 741 (2d Cir. 2013).
Plaintiffs allege that PepsiCo’s use of the term “diet” leads “consumers [to] reasonably
believe that [Diet Pepsi] will assist in weight loss, or at least healthy weight management, for
example, by not causing weight gain.” FAC ¶ 16. Faced with identical claims against PepsiCo’s
competitors, Judges Alsup, Orrick, and Daniels have held that no reasonable consumer would
understand a soft drink labeled as “diet” to be a weight-loss product. See Coca-Cola, 2018 WL
1070823, at *3 (“[A] reasonable consumer would simply not look at the brand name Diet Coke
and assume that consuming it, absent any lifestyle change, would lead to weight loss.”); Dr
Pepper, 2018 WL 1569697, at *6 (“Nothing on the label, packaging, or advertising of Diet Dr
Pepper makes the claim or even suggests that the product will assist in weight loss or healthy
weight management.”); Excevarria, 2018 WL 1569697, ECF. No. 56 at 82 (“The word ‘diet’
does not solely represent claims with regard to the loss of weight or the gain of weight by its
The Court joins in this holding, for two reasons.
First, the FAC reads “diet” out of context. “[I]n determining whether a reasonable
consumer would have been misled by a particular advertisement, context is crucial.” Fink, 714
F.3d at 742. Accordingly, “in resolving the reasonable consumer inquiry, one must consider the
entire context of the label.” Koenig v. Boulder Brands, Inc., 995 F. Supp. 2d 274, 288 (S.D.N.Y.
2014) (quotation marks omitted).
Here, the word “diet” does not stand in isolation. “Diet” modifies “Pepsi.” As the FDA
has explained, where a term such as “low calorie” “immediately preced[es] the name of the
food,” the juxtaposition naturally “impl[ies] that the food has been altered to lower its calories
with respect to other foods of the same type.” 21 C.F.R. § 105.66 (1989). Likewise here, “Diet”
immediately precedes “Pepsi,” and thereby connotes a relative health claim—that Diet Pepsi
assists in weight management relative to regular Pepsi. While neither the FAC nor plaintiffs’
brief in opposition so much as mentions regular Pepsi, reading “Diet Pepsi” without reference to
Pepsi deprives the term “Diet” of its essential referent. Cf. NLRB v. Federbush Co., 121 F.2d
954, 957 (2d Cir. 1941) (Hand, J.) (“Words are not pebbles in alien juxtaposition; they have only
a communal existence; and not only does the meaning of each interpenetrate the other, but all in
their aggregate take their purport from the setting in which they are used.”). The FAC does not
dispute that Diet Pepsi assists in weight management relative to regular Pepsi. On this basis
alone, plaintiffs cannot maintain a claim that reasonable consumers have been deceived by the
term “Diet Pepsi.”
Second, even if the word “diet” may sometimes identify weight-loss products (as in “diet
pills” or other products available in a pharmaceutical aisle), in the context of soft drinks, the term
unambiguously signals reduced calorie content relative to the non-diet version of the drink in
question. See Coca-Cola, 2018 WL 1070823, at *3 (“Reasonable consumers would understand
that Diet Coke merely deletes the calories usually present in regular Coke, and that the caloric
reduction will lead to weight loss only as part of an overall sensible diet and exercise regimen
dependent on individual metabolism.”). Dictionary definitions specifically defining “diet” in the
context of soft drinks confirms this. See, e.g., Diet (adj.), Webster’s Third New International
Dictionary, Unabridged, http://unabridged.merriam-webster.com/unabridged/diet (last visited
May 14, 2018) (“1: reduced in calories or without calories,” as in “a diet soft drink”); Diet (n.),

May 14, 2018) (as modifier “([o]f food or drink) with reduced fat or sugar content: ‘diet soft
Consistent with the foregoing, in this litigation, PepsiCo initially moved to dismiss on the
ground that no reasonable consumer could believe “Diet Pepsi was a weight-loss product.” Dkt.
17 at 16. In response, plaintiffs amended their complaint to incorporate a series of undated,
unsourced Diet Pepsi advertisements that allude or are claimed to allude to weight loss. See
FAC ¶¶ 18–21. The FAC alleged that these advertisements “emphasize the beneficial effects of
the product on body weight and composition,” and thereby caused consumers to believe that the
term “Diet” in “Diet Pepsi” connoted a weight-loss product. Id. ¶¶ 16–17. PepsiCo thereupon
dropped its argument that the operative complaint had not identified any “affirmative statements”
that Diet Pepsi “is specifically formulated and should be purchased and consumed for weight
loss or weight management.” Dkt. 17 at 17.
For several reasons, however, the advertisements contained in the FAC do not rescue that
pleading. First, the advertisements convey no more than that regular consumption of Diet Pepsi
has “beneficial effects” relative to regular consumption of high-calorie Pepsi. Second, even if a
particular advertisement could be read otherwise, the message or implication of a commercial
advertisement is not the measure of how a reasonable consumer would understand a nutrition
label term like “diet.” Advertisements no doubt inform consumer opinion. But plaintiffs have
This definition accords with the federal regulatory requirements associated with use of the term
“diet” prior to the NLEA’s enactment. See 21 C.F.R. § 105.66 (1989).
not adequately alleged that a message that they might decode PepsiCo’s advertisements to
convey about the health benefits of Diet Pepsi fairly measures how a reasonable consumer would
specifically understand the term “diet” as that term appears on a “Diet Pepsi” label. 5
To be sure, for purposes of this motion, the Court must accept the FAC’s claim that the
two plaintiffs, Manuel and Grossman, drew the inference that Diet Pepsi assists in weight loss or
weight management in an absolute sense, not merely relative to regular Pepsi. See FAC ¶¶ 54,
56. But a cause of action for false or misleading conduct cannot rest on an unreasonable reading
of label or advertising at issue. See Stewart v. Riviana Foods Inc., No. 16-cv-61157 (NSR), 2017
WL 4045952, at *10 n.22 (S.D.N.Y. Sept. 11, 2017) (“Satisfying the reasonable consumer
standard requires more than a mere possibility that [the defendant’s] label might conceivably be
misunderstood by some few consumers viewing it in an unreasonable manner.” (quotation marks
omitted)). The “reasonable consumer” test is an objective one. Goldemberg, 8 F. Supp. 3d at
478. And, objectively, reasonable consumers, well acquainted with diet soft drink labels that
plaintiffs admit are “ubiquitous,” see FAC ¶ 1, surely understand that “diet” soft drinks are
simply “lower calorie or calorie-free versions of their sugar-laden counterparts,” Dr Pepper,
2018 WL 1569697, at *6.
The FAC therefore does not adequately plead deception. Because a reasonable consumer
understands the “Diet” in “Diet Pepsi” to make—at most—a relative health claim in comparison
to the non-diet variant of the same brand, a plausible claim of consumer deception would require
more. It would require credible allegations—presumably based on scientific evidence—to the
effect that consumption of Diet Pepsi frustrates weight loss efforts relative to commensurate
As explained below, the FAC does not allege that PepsiCo’s advertisements are themselves
false or misleading. See infra Part III.D.
consumption of regular Pepsi. Plaintiffs do not make any such allegation or direct the Court to
evidence that would support such an allegation.
The FAC fails to state a claim for a second, independent reason: Even if reasonable
consumers would understand the “Diet” in “Diet Pepsi” to denote a weight-loss product—i.e., a
product that promotes weight loss in an absolute sense, not merely relative to regular Pepsi—the
FAC does not allege (other than conclusorily) that Diet Pepsi actually frustrates weight loss for
any segment of the population. Accordingly, even adopting a broader construction of “Diet”
than is fairly attributed to the word “Diet” in “Diet Pepsi,” the FAC fails to allege that this label
The FAC does allege that NNS are “likely to cause weight gain.” FAC ¶ 42. It purports
to base this conclusion on 14 scientific articles and studies. However, a review of these reveals
that none claim that NNS consumption causes weight gain. 6 Instead, the studies point only to a
non-causal association between NNS consumption and weight gain (or related health problems).
See FAC ¶¶ 28–34. Each study in fact expressly disclaims any generalizable causal conclusion:
“Our results . . . suggest that human individuals feature a personalized response to
[NNS], possibly stemming from differences in their microbiota composition and
function.” Jotham Suez et al., Artificial Sweeteners Induce Glucose Intolerance by

“Despite accumulating evidence of the existence of these associations, we are
cautious not to conclude causality between diet soda and the diabetic or pre-diabetic
condition. The possibility of confounding by other dietary and lifestyle/behavioral
factors cannot be excluded from these observational studies.” Jennifer A. Nettleton et

in the Multi-Ethnic Study of Atherosclerosis, 32 Diabetes Care 688 (2009), cited in
FAC ¶ 34, http://care.diabetesjournals.org/content/32/4/688.long.
The FAC also cites review articles extrapolating from existing studies. See FAC ¶¶ 24–
27. But these articles, too, disavow causal inferences:
“[I]ntervention trials consistently fail to document that NNS promote weight gain,
and observational studies provide only equivocal evidence that they might.
Reflecting these findings, conclusions from prior reviews are ambivalent about a
contribution of NNS to weight gain.” Richard D. Mattes, et al., Nonnutritive
sweetener consumption in humans: effects on appetite and food intake and their
putative mechanisms, 89 Am. J. Clinical Nutrition 1 (2009), cited in FAC ¶ 24,

if the FAC had adequately alleged the frequency and quantity of plaintiffs’ NNS consumption, or
a plausible biological mechanism through which NNS consumption frustrates healthy weight
management, see FAC ¶¶ 35–41, it does not make non-conclusory allegations that NNS
consumption causes weight gain, or even a risk of weight gain.
One “mini-review” cited at FAC ¶ 26 proposes that “research studies suggest that artificial
sweeteners may contribute to weight gain.” In support, however, it cites only cohort studies
finding “positive correlation between artificial sweetener use and weight gain,” childhood studies
that either could not “differentiat[e] between artificial sweetener users and non-users” or
indicated “the correlation between diet soda and BMI was not significant,” and interventional
studies suggesting only that “artificial sweeteners do not help reduce weight when used alone.”

cravings, 83(2) Yale J. Bio. & Med. 101–08 (June 2010), https://www.ncbi.nlm.nih.gov/pmc/
For this reason, evaluating complaints based on the same articles and studies at issue
here, Judges Alsup and Orrick reached a common conclusion: Plaintiffs’ claims have outrun the
science. See Coca-Cola, 2018 WL 1070823, at *4 (“With a conclusory wave of counsel’s hand,
[plaintiff] has overstated the actual science set forth in the citations.”); Dr Pepper, 2018 WL
1569697, at *6 (“[T]he studies do not allege causation at all—at best, they support merely a
correlation or relationship between artificial sweeteners and weight gain, or risk of weight gain.
But correlation is not causation, neither for purposes of science nor the law.” (citations
At bottom, plaintiffs have failed to allege a causal relationship between NNS
consumption and weight gain. Without evidence of causation, plaintiffs cannot establish actual
deception—i.e., that contrary to their expectations, plaintiffs “received a beverage whose
consumption is likely to lead to weight gain.” FAC ¶ 61.
Perhaps one day, scientific research will support such a claim. In that event, plaintiffs
may renew their challenge. See L-Tec Elec. Corp. v. Cougar Elec. Org., 198 F.3d 85, 87–88 (2d
Cir. 1999) (claims based on newly discovered evidence that could not have been discovered with
due diligence are not barred by res judicata). Plaintiffs’ FAC, however, rests on too spongy a
foundation for such a theory of deception to be sustained as viably pled: The review articles
cited in the FAC do no more than queue up for analysis by future researchers the issue whether
To be sure, associational data, properly considered pursuant to reliable expert methodology,
can, in conjunction with other evidence, sometimes suggest a likelihood of causation. See, e.g.,
In re Joint E. & S. Dist. Asbestos Litig., 52 F.3d 1124, 1128 (2d Cir. 1995) (citing A. Bradford
Hill, The Environment and Disease: Association or Causation, 58 Proc. Royal Soc’y Med. 295,
295–300 (1965)). As to the issue here, however, no scientist cited by the FAC or counsel has
found causality. See Brown et al., Artificial Sweeteners, supra (“Based on the [Bradford Hill]
criteria, causality is far from established with regard to artificial sweetener use and weight gain
there is a causal relationship between NNS consumption and weight gain. Because the FAC
asserts such a relationship as an ipse dixit, it fails to state a plausible claim of deception.
False Advertising Claims
In view of the foregoing, plaintiffs’ false advertising claim under New York General
Business Law § 350, along with the rest of plaintiffs’ claims, must be dismissed for failure to
allege adequately that the term “Diet” in “Diet Pepsi” is false or misleading. Nevertheless, in the
interest of completeness, the Court briefly addresses PepsiCo’s separate, specific objection to
plaintiffs’ false advertising claim.
PepsiCo argues that that claim is independently defective (1) for failure to allege
causation, in that plaintiffs do not claim to have seen the advertisements reprinted in the FAC,
and (2) as time-barred. See Mem. at 19–21. These critiques might well have purchase in a case
claiming that the reprinted advertisements were themselves false and misleading. But PepsiCo
misconstrues the FAC’s false advertising claim to so allege. The FAC bases its claim under
§ 350 solely on PepsiCo’s use of the term “diet” in advertising its product. It does not challenge
as actionable any print or video advertisement. See FAC ¶ 88 (“Pepsi’s use of the term ‘diet’ in
marketing Diet Pepsi is deceptive in light of the strong evidence that aspartame acesulfamepotassium and sucralose cause weight gain.”). The advertisements quoted in the FAC are cited
for a different purpose: to “show that PepsiCo’s messaging in extra-label advertising was”—
ostensibly—“consistent with Plaintiffs’ interpretation of ‘diet’ in the product’s brand name.”
Opp. at 23. In other words, these advertisements are offered to support plaintiffs’ (unavailing)
argument that a reasonable consumer would view Diet Pepsi as a weight-loss product, not as the
basis for a stand-alone false advertising claim. Accordingly, PepsiCo’s critiques do not supply
an independent basis to dismiss the FAC’s false advertising claim.
