At first glance, the document Dietary Guidelines for Americans 2025-2030 (The new American food guide) seems like progress. It talks about reducing ultra-processed foods, prioritizing whole foods, cooking more at home, and valuing natural foods. The expression "eat real food" appears as a mantra, and that alone is hard to criticize.

→ The problem begins when one examines what the document considers "real food" with a technical lens.

Throughout the pages, it becomes clear that the backbone of the guide does not include vegetables, fruits, legumes, and whole grains, as decades of research in nutritional epidemiology have indicated. The foundation built there is made of animal protein, whole dairy products, and animal fats.

→ The discourse is modern, but the nutritional structure is old.

That is precisely why, below, we objectively highlight the sections of the document that deviate from the most consistent current scientific evidence:

1. The exaggerated centrality of the protein

Right at the beginning, the guide establishes protein targets between 1,2 and 1,6 g/kg/day for the general population (page 2 - DGA).

This recommendation is typical for athletes, frail elderly individuals, or specific clinical situations, not for healthy adults.

The official recommendation (RDA) remains 0,8 g/kg/day. Most people already consume more protein than that. Pushing the entire population toward high consumption offers no proven benefit, but indirectly encourages increased consumption of meat, eggs, and dairy products.

→ This is not a physiological recommendation. It is a recommendation that guides dietary patterns.

2. Whole dairy products as a cornerstone of the diet.

The guide recommends three daily servings of whole dairy products (page 2 - DGA), treating them as a central food. The problem is that there is no scientific consensus that whole dairy products are superior, much less indispensable. Not to mention that several guidelines prioritize reducing saturated fat.

Calcium, protein, and vitamins can be obtained from many other sources. The longest-living populations on the planet do not consume high amounts of dairy products. Here, the choice seems more cultural and agricultural than nutritional.

3. Red meat treated as a neutral food.

The guide includes red meat among the desirable protein options (page 2 - DGA), ignoring the strong consensus that there is now linking its consumption to an increased risk of colorectal cancer, cardiovascular disease, and type 2 diabetes. The WHO classifies processed meats as carcinogenic.

→ Nevertheless, the document treats red meat as a neutral and desirable food.

4. Butter and tallow as "healthy fats"

In the fats section, the text lists butter and beef tallow as valid options (page 3 - DGA).

This contradicts decades of evidence that prioritizes unsaturated fats such as olive oil, nuts, seeds, and avocados.

This is a return to an outdated nutritional view. Tallow and butter are concentrated sources of saturated fat, associated with a poorer lipid profile.

5. Vegetables, fruits, and grains in secondary roles.

The suggested goals are modest: 3 servings of vegetables, 2 of fruit and 2-4 of whole grains per day (page 3 - DGA)

→ This is far below what is recommended by the WHO, Harvard, and the dietary standards associated with longevity.

→ The healthiest populations in the world have a diet based on whole grains and legumes.

→ The very food groups that offer the most protection end up being relegated to secondary roles. Here, vegetables become supporting actors while animal protein and dairy products become the main focus.

6. Criticism of refined foods turns into a silent war against carbohydrates.

The guide is correct in recommending a reduction in ultra-processed foods, but the problem is that in the text, foods like bread, crackers, and other grain-based products end up being placed on the same level as ultra-processed foods. This mix creates a dangerous implicit message that the problem is not industrial products, but carbohydrates themselves.

→ This construction may lead the reader to a disguised low-carb logic (page 4 - DGA).

7. The section on vegetarians and vegans is technically flawed and alarmist.

Huge list of possible deficiencies in vegans (page 9 - DGA)

Problems:

• It exaggerates deficiencies that do not appear in well-designed population studies of vegans.
• It puts protein as a risk (it isn't).
• It ignores the fact that omnivorous diets are also deficient in fiber, folate, magnesium, and potassium.

→ It does not mention that vegan diets are associated with:

• Lower BMI
• Lower cardiovascular risk
• Lower risk of diabetes
• Lower risk of cancer

The section on vegans and vegetarians is technically weak and lacks informative content.

8. Recommendations for children focused on meat, dairy, and eggs.

Examples of foods for babies: meat, whole dairy products, etc. (page 7 - DGA).

Ignore that:

✔ Legumes, tofu, and seed pastes are excellent options.

✔ Many countries already recognize the safe introduction of plant-based products.

9. The document mentions "real food," but promotes a pro-livestock dietary standard.

The narrative is:

Real food = meat + dairy + eggs + animal fats

That's not a scientific definition. It's an agricultural/political definition.

10. The microbiome is mentioned, but its main food sources are downplayed.

The guide discusses gut health and the microbiome (page 2 - DGA), but it doesn't emphasize legumes, whole grains, and fiber as a dietary staple. It's a clear conceptual inconsistency.

A political narrative in a document that should be technical.

11. Complete lack of evidence regarding plant-based diets and longevity.

No mention of:

• Adventist Health Study - https://pubmed.ncbi.nlm.nih.gov/23836264/

• EPIC-Oxford - https://pubmed.ncbi.nlm.nih.gov/35934687/

• Blue zones - https://pubmed.ncbi.nlm.nih.gov/35780634/

• Meta-analyses on plant-based diets - https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2025.1518519/full

This is a very significant scientific omission.

12. Explicit political bias in the opening text.

The document's introduction (page 1 - DGA) uses ideological language that is unusual for nutritional guidelines. Dietary guidelines should be based on scientific evidence, not political narratives.

The central problem:

The guide sells the idea of ​​"real food," but redefines that concept as:

meat + dairy + eggs + animal fats

While the science of longevity shows that the most protective dietary patterns are based on:

vegetables + fruits + legumes + whole grains + seeds + nuts

→ The pyramid was inverted.

Reducing ultra-processed foods is an important step, and encouraging homemade food is too. But using this rhetoric to put animal protein, whole dairy products, and saturated fats back at the center of the diet is a step backward disguised as modernity.

The discourse is new. The scientific basis is not.

If the real goal is to reduce chronic diseases, increase longevity, and improve public health, the evidence points to a clear path: predominantly plant-based diets.

→ Ignoring this in a national food guide isn't just an omission. It's negligence.
