A trip to the supermarket these days is as much a marketing battleground as a chance to stock up on groceries. With promises like “heart healthy,” “high in protein,” and “low-carb” splashed across everything from yogurt to granola bars, health-conscious Thai shoppers may feel reassured about their food choices. But new research and mounting global scrutiny reveal that these claims are often more about sales than substance—prompting both consumers and regulators to rethink how healthy our processed foods really are (Yahoo Lifestyle, 2025).
Why does this matter for Thai consumers? Thailand is increasingly facing health challenges linked to diet, including rising rates of obesity, type 2 diabetes, and cardiovascular diseases—a trend also seen across Asia. As more Thais adopt modern eating habits, including a greater dependence on processed and convenience foods, the marketing tactics used by food companies directly impact public health efforts. For shoppers trying to make “good” choices, labels can be confusing, misleading, and, in some cases, harmful when they mask unhealthy ingredients behind buzzwords.
Experts call this phenomenon “nutriwashing” or “healthwashing.” It refers to the use of loosely regulated buzzwords to present products as healthier than they actually are. According to Lindsay Malone, a registered dietitian and nutrition instructor at Case Western Reserve University, “These claims influence consumer decisions by creating the illusion of healthiness, leading shoppers to choose products they believe are better for them when, in reality, they may still be highly processed and nutritionally poor.” Cereals labeled as “heart healthy” may still contain excessive sugar; “high-protein” yogurts can be full of artificial sweeteners, and snacks that tout “real fruit” may derive their flavors from artificial sources (Yahoo Lifestyle).
A recurring example, both in the US and increasingly in Thailand, is the use of the word “natural.” While it sounds reassuring, Malone explains that the term is largely unregulated and can include processed ingredients, artificial additives, and even high fructose corn syrup. The deceptive practice extends to manipulating serving sizes to produce seemingly “healthier” nutrition profiles—such as being able to legally advertise a product as “trans-fat free” so long as each serving contains less than 0.5 grams of trans fats, even if real-world consumption is much higher. This loophole can easily mislead buyers who use creamer or other products more liberally than the official portion size (Yahoo Lifestyle).
Globally, regulators are starting to crack down on misleading claims. In the United States, the Federal Trade Commission (FTC) and the Food and Drug Administration (FDA) have established categories for claims: “health claims” (like “lowers risk of heart disease”) must be backed by scientific research, “nutrient content claims” (“high in protein”) must meet specific criteria, and “structure/function claims” (“boosts metabolism”) must disclose if the FDA hasn’t evaluated the statement (FDA 2024 update). Legal action has ramped up, with big-name companies facing lawsuits—Kellogg’s settled with the FTC after making unsubstantiated claims about children’s cereal, and Kraft Heinz is battling class action over labeling its Capri Sun drink as “All Natural Ingredients.”
Thailand, too, is updating its approach as it joins the global fight for honest, clearer food labeling. Recent notifications from the Thai Food and Drug Administration introduce stricter requirements on claims used on product packaging, including the need for scientific evidence and clearer definitions for terms like “best before” and permissible health claims (Thai FDA News, Tilleke & Gibbins, 2024). Thailand is also moving to create a positive list of approved health claims to encourage transparency and protect consumers, reflecting a new era of stricter oversight (FDA Thailand, 2024).
Yet, even as regulations tighten, marketing creativity will always find loopholes. Scholars warn that ultra-processed foods—loaded with preservatives, sugar, salt or artificial coloring—are still routinely marketed as healthy, not just in the West but in ASEAN markets, including Thailand (Frontiers Public Health). Research published in 2024 indicates that health claims continue to sway consumer perception, sometimes against their own health interests (Wiley, 2024). Thai consumers also show a tendency to equate health claims—words like “organic” or “non-GMO”—with genuine health benefits. However, these often do not reflect the nutritional profile or processing methods involved (see also Wikipedia).
While Thai food culture is proud of its rich, diverse, and (when home-cooked) often healthy cuisine—think som tam, grilled fish, or bowls of fresh rice and vegetables—the rapid urbanization and expansion of supermarket culture pose new risks. The traditional advice of eating freshly cooked meals, choosing items “แม่ปลูกเอง” (homegrown by mum), or shopping at a morning market echoes what experts recommend: buy single-ingredient foods whenever possible. “The best foods usually don’t have marketing claims at all,” says Malone. “You don’t need to decode the packaging of a banana or a sweet potato—you know what it is and that it’s going to be healthy for you.”
For the Thai context, this advice is especially practical. Avoiding ultra-processed foods for fresh ingredients is already part of the national culinary heritage, where “อาหารบ้านๆ” (simple, home-style food) is revered for flavor and health. However, as processed foods become more common in Thai lunchboxes, caution is warranted. Reading the ingredient list, ignoring flashy claims on the packaging, and watching for “red flag” ingredients (high-fructose corn syrup, hydrogenated oils, artificial colors like Red 40 and Yellow 5) can help prevent being misled (Yahoo Lifestyle). Checking real serving sizes and understanding that “sugar-free” often means “full of artificial sweeteners” will empower you to make better decisions for yourself and your family.
Looking to the future, Thailand’s new labeling laws, coupled with growing consumer awareness, hold promise for more honest food marketing. However, consumers remain the last line of defense. As food companies adapt their marketing, shoppers will need to stay skeptical and informed. Perhaps the best advice comes from food writer Michael Pollan: “Don’t eat anything your great-grandmother wouldn’t recognize as food.” In a Thai context, that likely means sticking to foods with simple, recognizable ingredients—a bowl of rice and grilled fish rather than a “high-protein” bar with 27 ingredients.
For Thai readers, the call to action is clear: Protect your health by looking past the claims on the front of the package and focusing on the back. Read the nutrition label; know what common additives, sugars, and artificial ingredients look like in both English and Thai. Buy local fresh produce where possible—supporting farmers in Chiang Mai or Chantaburi, for example, brings both health and economic benefits. And for packaged foods, be wary of marketing promises and arm yourself with knowledge. As Thailand continues to balance tradition with modernization, staying savvy about what goes into your body may be the most “heart healthy” habit of all.
