Less meat, more plants: top US heart body’s diet advice at odds with MahaAmerican Heart Association bucks Trump administration line to suggest prioritizing plant-based protein over meat In contrast to the federal government’s recommendation of use of beef tallow and consumption of red meat, the AHA pushed for plant-based proteins such as legumes, nuts and seeds. Photograph: Allen J Schaben/Los Angeles Times/Getty Images The American Heart Association’s new nutrition guidance, released on Tuesday, emphasizes a dietary pattern rich in vegetables, fruits and whole grains, prioritizing plant-based protein over meat. It also suggests limiting the use of sugar, salt and ultra-processed foods and replacing full fat dairy with non-fat and low-fat dairy. Donald Trump earlier this year announced a new slate of dietary guidelines that recommended Americans eat more protein from both animal and plant sources, and encouraged the consumption of full-fat dairy. In contrast to the federal government’s recommendation of use of beef tallow and consumption of red meat, the AHA is pushing for plant-based proteins such as legumes, nuts and seeds, choosing low-fat or fat-free dairy, and, when consuming red meat, selecting lean cuts, avoiding processed forms and keeping portions small. The Trump administration and health secretary Robert F Kennedy Jr’s push to “Make America healthy again” has focused on the removal of synthetic dyes, other chemical ingredients, ultra-processed foods, consumption of less sugar and seed oils. The AHA also suggests Americans choose sources of unsaturated fats, avoid ultraprocessed foods and minimize intake of added sugars in beverages and foods. The organization recommended Americans to prepare foods with minimal or no salt, and limit the intake of alcohol. The guidance also recommended children can and should begin following a heart-healthy dietary pattern starting at one year old. The AHA’s guidance was aligned with the US Food and Drug Administration’s dietary guidelines on major issues, a spokesperson from the FDA said, adding they looked forward to working collaboratively with AHA. The AHA, which is the nation’s oldest and largest voluntary organization dedicated to fighting heart disease and stroke, releases dietary guidance about every five years to promote cardiovascular health.

Introduction
The escalating prevalence of metabolic syndrome represents a critical public health issue. Emerging anecdotal evidence suggests that various dietary interventions, including carnivore, vegan, and standard American diets (SAD), may offer significant benefits. This study aims to rigorously evaluate these claims through a controlled, blinded, and comprehensive approach.

Impact and Significance
This study aims to fill critical gaps in our understanding of how distinct dietary patterns influence metabolic health. By employing a rigorous methodology, including controlled dietary interventions and strict supplement monitoring, the study will provide high-quality evidence to inform future dietary guidelines and public health recommendations.
Conclusion
Addressing the metabolic health crisis requires evidence-based dietary interventions. This study represents a significant step towards understanding the impacts of carnivore, vegan, and SAD on metabolic health, offering a blueprint for future nutritional research and public health policy.
