By Marion Nestle June 04 2026 The eye-rolling protein craze: some thoughts Nutritionists like me cannot understand why people think they need more protein, so much so that the food industry is putting protein into everything. Most Americans consume close to twice the amount of protein needed, and practically anyone who consumes enough calories gets plenty.  Protein is in lots of foods and it’s really hard not to get enough unless you aren’t eating much. I’m endlessly entertained by protein in everything, and am tracking its effect on the food industry. Guess what.  There’s a shortage. Protein powder shortage threatens America’s biggest food craze: Companies are now grappling with whether to raise prices at a time when consumers are already reeling from a prolonged period of inflation. The food industry views the protein craze as a growth opportunity. How protein is shaping active nutrition in 2026:  Sustained demand for protein continues to define the active and performance nutrition space. But where are the growth niches?… Read more And it’s not just food.  Look what’s happening with drinks. From coffee to soda: How protein is making waves in beverage innovation:  Drinks are a new frontier for protein innovation… Read more And just because a product contains protein, doesn’t necessarily mean its healthy. The new paradox: Protein vs processing:  Protein is the snack industry’s hottest claim but if the foods delivering it are still ultra-processed, the sector may be building its next health halo on shaky ground… Read more Unusual sources of protein are not doing so well these days. Insect protein’s reality check: High costs, failed ventures and slower-than-expected market growth temper early optimism. But peptides—smaller chains of amino acids—are another craze, despite lack of evidence for their benefits. Peptides Move From Fringe Biohacks to Functional Food Frontier:  As demand surges for targeted health solutions, Nuritas’ Nora Khaldi discusses how AI is transforming peptide discovery, and why food and beverage may be the industry’s next big play… Listen now As always, I’m for getting protein from foods, largely plant sources.  Yes plant proteins sometimes are low in essential amino acids but the low ones differ among plant sources, so variety takes care of gaps: rice, wheat, and corn with beans, peanut butter sandwiches.  Easy.   The post The eye-rolling protein craze: some thoughts appeared first on Food Politics by Marion Nestle      Related Posts Lawsuit #1: David’s protein bars   Now Available: What to Eat Now My new book, What to Eat Now, is officially out!

By Marion Nestle June 03 2026 American Journal of Public Health series on Ultraprocessed Foods: My Editorial The American Journal of Public Health has just published a series of papers on ultraprocessed foods to which I contributed this editorial.  These papers are released today as part of the launch of new initiative, Fed UP! aimed at establishing policies to help reduce consumption of ultraprocessed foods and prevent their harm to health. Press releases for the series and campaign are here and here (longer, more quotes).   The briefing materials for the series and campaign are here. The other papers are on the AJPH webpage dedicated to this series; all are open access. And here is my editorial. The Politics of Ultraprocessed Foods: Dietary Guidelines for Americans Marion Nestle, PhD, MPH On January 7, 2026, the Trump administration’s Departments of Health and Human Services (HHS) and Agriculture (USDA) jointly released the 2025–2030 Dietary Guidelines for Americans. For the first time since they were established in 1980, these called for “a dramatic reduction in highly processed foods laden with refined carbohydrates, added sugars, excess sodium, unhealthy fats, and chemical additives.” The actual guideline, one of eight, says “Limit highly processed foods, added sugars, & refined carbohydrates.” 1 Although these statements do not use the term “ultraprocessed,” that is clearly what they mean. The guidelines are based on a commissioned scientific foundation report that refers repeatedly to ultraprocessed foods and cites major studies of their health effects.2 Those studies, largely observational, used the Nova classification system to divide foods into four categories based on their degree of processing: unprocessed or minimally processed (Nova 1), processed culinary ingredients (Nova 2), processed (Nova 3), and ultraprocessed (Nova 4).3 The scientific foundation report notes three reasons for avoiding the Nova 4 term: no consensus definition of “ultraprocessed” exists, defining refined starches and sugars as Nova 2 underestimates dietary intake of Nova 4 foods, and the Nova system classifies some nutrient-dense foods as ultraprocessed. On this basis, the guidelines use “highly processed” as a euphemism. Even so, the very mention of processing in the US dietary guidelines must be considered an important forward step. In advising limits on highly processed foods, HHS and USDA reversed the decision made by the Biden administration’s Dietary Guidelines Advisory Committee (DGAC). That committee judged the category of ultraprocessed to be too ambiguously defined, and the observational evidence for its harm to health too subject to error, to warrant an “eat less” recommendation.4 I view this decision as overly cautious. Yes, observational studies can only demonstrate association, not causation, but of more than 100 studies of ultraprocessed diets and health, nearly all found such diets to increase risks for chronic disease and overall mortality.3 Furthermore, the DGAC excluded consideration of the one exceptionally well-controlled randomized clinical trial available at the time. The participants in that study were housed in a metabolic ward—they could not lie or cheat about what they were eating—and given a diet of either minimally processed or nutritionally comparable ultraprocessed foods. The study results were unexpected and dramatic; the participants consumed an average of 500 calories a day more on the ultraprocessed diet, without realizing it.5 The DGAC eliminated this trial from consideration because it had set criteria for inclusion that required studies to last longer and involve more participants.6 I thought the DGAC should have made an exception for this trial; metabolic ward studies are enormously expensive and few human volunteers are willing to be locked in one for more than a few weeks. At issue is the preponderance of research; scientists can interpret it differently. The Trump administration’s commissioned research review found “robust and consistent adverse associations between HPF [highly processed food] consumption and a broad range of chronic health outcomes, often in a dose–response fashion,” and concluded that “the current evidence base provides a strong rationale for immediate action at the individual, population, institutional, and policy levels.”7 Many researchers and nutrition professionals, including me, agree with this assessment.8 This guideline is new, but most of the other 2025 dietary guidelines are consistent with long-standing scientific consensus on the benefits of eating more vegetables, fruits, and whole grains, and limiting intake of added sugars, sodium, and alcohol, although they call for greater restriction of sugars and less precise (vague) restriction of alcohol. The guidelines sharply diverge from consensus in recommending a doubling of protein—a euphemism for meat—and in not emphasizing plant foods more strongly. They promote greater intake of meat along with full-fat dairy, butter, and beef tallow, but inconsistently limit saturated fat to 10% of calories.1 The agencies’ fact sheet makes the politics explicit; it uses the word “evangelizing.” Its major point: previous governments have lied to you about dietary risks, and you need to take personal responsibility for what you eat. In doing so, the guidelines reject concerns about health equity—and, therefore, policies that might address social determinants of health—as deserving of consideration.9 Despite promises that the guidelines would be free of conflicts of interest, four of the nine writers of the research reviews report financial ties to meat and dairy industry groups, and three more disclose ties to other food industries.3 The conflicted interests and emphasis on animal-based foods make these guidelines appear to have been captured by the meat and dairy industries.10 I cannot determine whether these guidelines were influenced more by corporate capture or by the personal ideologies of the agency secretaries; they, after all, selected the individuals who wrote the research reviews and are responsible for what the guidelines say. I also do not know how even “highly processed” made it into the guidelines in the face of what surely must have been intense food industry opposition. The food industry, joined by some nutrition scientists, much prefers guidelines based on nutrient content: sugar, salt, fat. Doing so permits the few frequently cited nutrient-dense Nova 4 products—some whole wheat breads, yogurts, and power bars, and plant-based meats—to be considered processed, not ultraprocessed. Critics of the ultraprocessed concept endlessly invoke the same arguments: there is no scientific consensus on the meaning of the term, and the concept risks undermining “established, evidence-based nutrition strategies,” thereby shifting “the focus away from the most important thing about food which is the nutrition aspect.”11 But thoughtful rebuttals to these arguments note that food misclassifications do not appear to change study conclusions; well-controlled clinical trials have now been repeated with similar, biologically plausible results; the mechanisms of action of ultraprocessed foods are under study; and even “healthy” ultraprocessed foods induce greater calorie consumption.2 Behind food industry arguments is the enormous profitability of ultraprocessed products. Indeed, the very purpose of ultraprocessing is profit maximization—using low-cost ingredients to create irresistible and long-lasting products—so much so that this goal is built into its Nova definition.2,9 The food industry’s objection to the inclusion of processing as a consideration in dietary guidelines comes down to this: eating less is bad for business. The call for limits on ultraprocessed foods may be groundbreaking in US dietary guidelines, but in 2015, Brazil issued guidelines that included advice to “Make natural or minimally processed foods the basis of your diet.”12 Unlike US guidelines. these were based on the idea that healthy diets should derive from socially and environmentally sustainable food systems. This is a major conceptual difference from the US approach, which emphasizes personal responsibility above all others. When individuals are deemed entirely responsible for their own dietary intake, government policies need focus only on education. If objections to the guidelines from the food industry have been mild so far, it is surely because its leaders know that education is not enough to change dietary behavior. They much prefer education to policies aimed at regulating product contents and marketing. But to really help people reduce intake of ultraprocessed foods, we need a wide range of policy options—taxes, subsidies, marketing, procurement, product placement13—aimed at making healthier foods more available, accessible, and affordable.
