Robert F. Kennedy Jr. is redefining the ‘healthy’ American diet—prompting food companies to make 5 major changes to keep up

Robert F. Kennedy Jr.’s vision for a healthier America has sparked the most substantial transformation in federal nutrition policy in decades. At the helm of the “Make America Healthy Again” movement, Kennedy—serving as head of Health and Human Services—has implemented sweeping changes that are beginning to influence what’s available in grocery stores. A core aspect of this shift is a fundamental reevaluation of how the government approaches nutrition. 

“The underlying philosophy is that consuming whole foods and avoiding ultra-processed foods leads to a significantly healthier diet,” Marion, a nutrition policy expert, told .

“The MAHA movement is a pushback against the ‘industrial food complex and pharmaceutical companies that have engaged in deception, misinformation, and disinformation regarding public health,’” President Donald Trump stated in a Truth Social post announcing Kennedy as his choice for HHS Secretary. The movement has gained momentum, with nearly 10 parents indicating their support. 

Over the past year, Kennedy and the Trump administration have drastically reshaped American food policy. Here are five ways the MAHA movement is already altering supermarket shelves.

1. Dairy’s revival 

On January 7, the Department of Agriculture updated its dietary guidelines, overhauling the traditional food pyramid. This update placed a focus on full-fat dairy and all types of fats, including both healthy and saturated fats. The guidelines now suggest three daily servings of full-fat dairy, with Kennedy stating the USDA was “putting an end to the war on saturated fats.” Whole grains, once viewed as the cornerstone of diets, were de-emphasized. “It was truly inverted before,” RFK Jr. noted when introducing the guidelines.

Yet the dairy trend was gaining traction long before the food pyramid update. In 2024, Americans consumed 650 pounds of dairy per person, with butter consumption reaching an all-time high. USDA data shows yogurt and cottage cheese consumption also rose sharply. Conversely, plant-based milk sales have declined, with brands like Oatly—renowned for its oat milk—reporting a drop in U.S. sales.

2. Beef tallow and seed oil backlash

Kennedy has elevated [the issue] from a niche concern to a policy and cultural focus, leveraging his role as HHS Secretary to repeatedly challenge the health and safety of canola, corn, and similar oils. Though he hasn’t banned seed oils, federal nutrition messaging now highlights “healthy fats,” promoting animal fats like [beef tallow] as alternatives. However, other nutrition experts remain unconvinced.

“The idea is that eating natural, whole foods helps you feel full faster, reducing the urge to eat other items,” Nestle told . “Whether this holds true remains to be seen.” 

Nestle notes that high intake of animal fats may be linked to health issues such as heart disease: “People on diets high in animal fats tend to have higher blood cholesterol and a greater risk of heart disease.”

Food and beverage companies like [PepsiCo] have announced plans to remove canola and soybean oil from Lay’s and Tostitos chips, with smaller firms like Real Good Foods following suit by offering “seed oil-free” frozen products.

3. Saying bye to artificial dye

Last April, Kennedy announced the U.S. [would regulate] synthetic dyes, labeling them “petroleum-based chemicals” that are toxic and harmful to children’s health. Since then, the health secretary has coordinated with regulators to phase out the most common synthetic dyes, replacing them with natural alternatives like [astaxanthin], a colorant derived from algae.

Several companies—including [Frito-Lay] and [Kraft Heinz]—have already removed synthetic dyes from their products, meaning some Doritos and Cheetos will appear colorless or paler on store shelves. Other firms—including [Ferrara], Utz, and Campbell’s—have pledged to eliminate dyes within the next few years. Mars Wrigley also revealed that Skittles, M&Ms, and Extra Gum will be available without artificial colors.

As a result, grocery stores are likely to feature fewer neon and fluorescent-colored products, more “no artificial colors” labels on packaging, and a growing number of naturally colored food and beverages in the snack aisle.

4. ‘Protein maxxing’

From Starbucks’ protein lattes and matcha drinks to Sweetgreen’s 106-gram protein bowl, protein has become a ubiquitous selling point for brands. This trend aligns with Kennedy’s effort to position protein as the central macronutrient in his nutrition overhaul. Kennedy’s new federal guidelines, released earlier this month, recommend 1.2 to 1.6 grams of protein per kilogram of body weight daily and urge Americans to “prioritize protein at every meal.” 

“That’s already what people are eating,” Nestle told . “So no one needs to change their protein intake. Most people are already consuming twice the protein they require.”

Nonetheless, grocery aisles have transformed amid America’s protein craze, with shelves stocked from protein Cheerios to protein ice cream from brands like Protein Pints, which saw significant revenue growth in 2025, exceeding $10 million.

5. Swapping out high-fructose corn syrup

Kennedy has also launched a campaign against high-fructose corn syrup (HFCS), framing the sugar substitute as a key ingredient in a disease-promoting food system. Some brands, including Tyson and [Kellogg’s], have committed to removing HFCS from their products.

Despite federal changes and a shift toward messaging about natural foods and high-protein diets, Nestle notes that Americans still prioritize cost over dietary preferences when shopping.

“Nobody follows dietary guidelines,” she said. “As long as ultra-processed foods are cheaper than whole foods, that’s what people will buy—because they have no other option.”
