## New US dietary guidelines under scrutiny The new US dietary guidelines, presented by Health Secretary Robert F. Kennedy Jr., have stirred up controversy. Contrary to expert recommendations, they promote the consumption of red meat, butter, and beef tallow, foods often associated with cardiovascular risks. ## Questionable recommendations The guidelines, which influence food assistance programs and school lunches, present a "new pyramid" of food that places protein, dairy, and "healthy" fats at the top, along with fruits and vegetables. This representation has been criticized as outdated and potentially misleading. Experts prefer the image of a plate to illustrate a balanced diet. In addition, the guidelines recommend an increased protein intake, exceeding previous indications. This increase could lead to excessive consumption of calories and saturated fats, according to some nutritionists. ## Criticism of the decision-making process Several nutrition scientists have expressed perplexity regarding the changes made, pointing out that the new recommendations are not reflected in the 2024 scientific report. Some experts, who contributed to previous guidelines, preferred not to comment officially, calling the decision-making process "opaque." ## Implications for public health The new dietary guidelines could have a significant impact on public health, influencing the eating habits of Americans and the country's nutritional policies. It remains to be seen whether these recommendations, in contrast to established scientific evidence, will lead to improvements or deteriorations in the health of the population.
