The heavy emphasis on full-fat dairy, including butter, is consistent with Kennedy’s rhetoric. But the written guidance actually maintains the long-standing recommendation that Americans limit their saturated fat (found in high levels in full-fat dairy) to less than 10 percent of their total calories. For a standard 2,000-calorie diet, this would be less than 22 grams per day. When asked if the generated menu followed that recommendation, Grok said no. In fact, depending on the options, it can be more than double, potentially more than 50 grams.
What about protein? That’s also usually over the limit. Recommended protein intake varies depending on factors such as weight, age, exercise level and pregnancy status. But the general recommendation is to get 0.8 grams per kilogram of body weight, or about 0.36 grams per pound. Americans generally already meet this recommendation. Kennedy’s guidance increases protein to 1.2 to 1.6 g/kg (or about 0.54 to 0.72 g/lb).
For a 150-pound person, the old and new recommendations for daily protein are 54 grams and 81 grams-108 grams, respectively. (The USDA has a calculator for your own recommendations, which still uses the old protein recommendation.) Groke’s interpretation of Kennedy’s guidance produced a menu with up to 180 grams of protein per day.
While the meal plan exceeded recommendations for saturated fat and protein, it fell short of fiber, a vital nutrient that Americans already eat too little of. In fact, most Americans eat less than half the recommended amount of fiber, which is found in fruits, vegetables, grains and legumes. The new guidance maintains daily fiber recommendations, which are typically 25 grams for women and 38 grams for men. But Grok’s “realistic” estimate for fiber in a meal plan ranged from 25 to 35 grams, which was less for men.
Overall, Grok concluded that “Based on extensive fact-checking and expert consensus, RFK Jr. is not a credible source on health matters. His claims often lack evidence, promote distrust in institutions, and lead to harmful consequences.”
So where does this leave Americans looking for trustworthy nutrition advice? Grok helpfully notes that “many experts still prefer options like Harvard’s Healthy Eating Plate, which gives more priority to plants and limits red meat/dairy, based on extensive epidemiological data.”
