Abstract
Our read is that butter, particularly from grass-fed ruminant animals, offers several health benefits, including improved gut health, reduced inflammation, and immune system support.
It contains beneficial compounds like butyric acid, stearic acid, and fat-soluble vitamins, and may aid in satiety and hormonal balance.
However, concerns exist regarding potential cardiovascular risks with excessive consumption, the quality of some butter brands, and the ongoing debate with institutions like Harvard regarding saturated fats.
Method
To maximize benefits, consume butter from ruminant animals not fed corn and soy, and use it for sautéing or adding fat to meat. One tablespoon per day can improve gut health, and there may be no limit to consumption without weight gain due to satiety mechanisms.
Evidence detail
01Paul Saladino claimed (2x) that one tablespoon of butter per day can significantly improve gut health.
02Paul Saladino claimed (2x) that butter contains butyric acid, stearic acid, and fat-soluble vitamins.
03Paul Saladino claimed (1x) that butter lowers CRP and inflammation.
04Paul Saladino claimed (1x) that butter is beneficial for the immune system.
05Paul Saladino claimed (4x) that butter contains butyrate, which is beneficial for conditions like IBS and inflammatory bowel diseases.
Conflict Watch
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Paul Saladino claimed (2x) that consuming desiccated testicle with butter or fat can serve as a form of testosterone replacement therapy.
07Paul Saladino claimed (1x) that consuming whole, unprocessed foods like meat, unprocessed plant foods, butter, tallow, and eggs does not lead to weight gain because satiety mechanisms prevent overconsumption.
08Paul Saladino claimed (1x) that consuming starch with butter results in faster free fatty acid rebound and satiation, whereas starch with margarine leads to a drop in free fatty acids and subsequent hunger.
09Paul Saladino claimed (1x) that for insulin-sensitive individuals, consuming whole dairy fat, including butter and raw whole milk, is associated with improved cardiovascular outcomes or is neutral to protective.
10Paul Saladino claimed (5x) that animal fats like butter and tallow are preferred for adding fat to meat over cooking oils.
11Paul Saladino claimed (1x) that there is no limit to how much butter one can eat without causing weight gain, and it may increase satiety and improve hormonal profiles.
12Paul Saladino claimed (1x) that to reduce polyunsaturated fatty acids, consume abundant animal fats from ruminant animals not fed corn and soy, minimize linoleic acid intake, avoid fish oil, and increase stearic acid intake from sources like tallow, butter, and suet.
13Andrew Huberman claimed (1x) that the Minnesota Coronary Experiment found that for every 30-point drop in LDL cholesterol, the risk of death from heart attacks or strokes increased by 22% when participants consumed corn oil compared to butter.
Caveats
Our read is that while butter offers benefits, there are notable disagreements and risks. Harvard claims that saturated fats from butter increase cardiovascular disease risk, recommending replacement with seed oils (Paul Saladino, 1x). Andrew Huberman (1x) noted that consuming excessive amounts of butter increases cardiovascular risk and can negatively affect blood lipids, typically by increasing LDL. Some brands, like Kerrygold, have faced scandals for not being fully grass-fed and for containing PFAS chemicals in packaging (Paul Saladino, 1x). Peter Attia (1x) stated that coconut oil is as unhealthy as beef fat and butter. Paul Saladino (1x) also mentioned that saturated fat from butter may be harmful by creating lipid rafts and endotoxemia, dependent on underlying gut dysbiosis.
What would change this verdict
Our read is that the verdict would change if new evidence emerged consistently demonstrating significant, widespread adverse health outcomes from moderate butter consumption from high-quality sources, or if the claims regarding its beneficial compounds and satiety effects were disproven. Conversely, stronger evidence supporting its cardiovascular neutrality or benefits for a broader population would further solidify the positive verdict.
