- Results
Dairy: 'When consuming dairy, include full-fat dairy with no added sugars. Dairy is an excellent source of protein, healthy fats, vitamins, and minerals'; goal 3 servings/day (2,000 kcal pattern). Fats: 'When cooking with or adding fats to meals, prioritize oils with essential fatty acids, such as olive oil. Other options can include butter or beef tallow'; 'In general, saturated fat consumption should not exceed 10% of total daily calories'; 'More high-quality research is needed to determine which types of dietary fats best support long-term health.' Children: 'Full-fat dairy products are important for children to help meet energy needs and support brain development'; full-fat yogurt and cheese listed among complementary foods; after 12 months infant formula replaced by whole milk; 'Adequate calcium and vitamin D are vital for peak bone mass' (adolescents). Pregnancy: pregnant women should consume nutrient-dense foods 'including ... calcium-rich dairy'.
- Absolute risks
not applicable
- Authors' conclusion
Prioritise whole, nutrient-dense foods including dairy and healthy fats; limit highly processed foods; keep saturated fat at or below 10% of energy.
6. Strengths
- Current (January 2026) national guideline
- Explicit statements on dairy for children and pregnancy
- Retains the 10% saturated-fat limit
7. Weaknesses
- Policy document; the evidence review behind it was not read
- Departs from earlier US guidance on full-fat dairy and animal fats; scientific basis contested (not assessed here)
- Not a systematic review
8. Risk of bias
- Orienting tool
- none applicable
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- not assessable
- Rationale
Guideline; AGREE-type appraisal not performed.
9. Assessment of the statistical interpretation
No statistics; statements are recommendations.
10. Relevance to the specific claim
Even the most recent guideline that is friendly to full-fat dairy and butter recommends milk, yogurt and cheese (3 servings/day), including for children and pregnant women, and keeps saturated fat at or below 10% of energy while prioritising olive oil.
11. Independent contrary findings
WHO (I-FAT-08) and European bodies recommend lower-fat dairy and replacing saturated fat with unsaturated fats.
12. Transferability to Germany and Europe
US guideline; dairy-related advice is consistent with UK NHS advice (I-DRY-123).
13. Overall methodological judgement
Useful as a current official position: it supports dairy (including fresh milk and yogurt) and treats butter as an option, not as a preferred fat.

14. Open questions
Evidence base of the 2025-2030 changes regarding full-fat dairy and butter.
15. Linked fact checks
- Milk is a 'substitute for blood' and carries every hormone, pesticide and antibiotic the animal received; therefore milk must be avoided. – Studies contradicting or limiting the claim
- Fresh milk, yogurt (incl. laban rayeb, ayran, labneh) and white/cottage cheese are harmful and must be avoided, whereas aged cheeses (cheddar, mozzarella, romi), processed cheese triangles, cream (qeshta), butter and ghee are allowed. – Studies contradicting or limiting the claim
- Natural fats such as baladi ghee and butter are not a cause of clogged arteries (contrary to the previously dominant view); 'good fats do not stick'. – Studies with mixed or unclear results
- Olive oil is an allowed fat in the system. – Studies supporting the claim
