Macronutrient Breakdown — per 100g
Butter is 80% fat, 16-17% water, ~2-3% milk solids. Clarified butter (ghee): ~900 kcal/100g (no water). Unsalted butter: 11mg sodium. Salted butter: ~580mg sodium/100g. Grass-fed butter has more vitamin K2, CLA, and omega-3.
Micronutrient Highlights
Butter Health Facts
Vitamin A — 97% of Daily Value
Butter is one of the richest dietary sources of preformed vitamin A (retinol) — providing 684µg per 100g (76% DV). Unlike beta-carotene from plants, retinol in butter is directly bioavailable without conversion. Vitamin A is essential for vision, immune function, and skin health. Grass-fed butter has significantly more vitamin A and beta-carotene (which gives it a deeper yellow colour) than grain-fed butter.
Butyrate — Anti-Inflammatory Fatty Acid
Butter fat contains approximately 4g of butyrate per 100g — a short-chain fatty acid that is the preferred energy source for colon cells (colonocytes). Butyrate maintains gut lining integrity, has powerful anti-inflammatory effects, and reduces cancer cell growth in colon cancer research. Interestingly, gut bacteria produce butyrate from dietary fibre fermentation — butter provides preformed butyrate directly.
The Saturated Fat Reconsideration
Butter is approximately 51% saturated fat — long considered the main dietary driver of cardiovascular disease. However, a comprehensive 2020 review of 35 meta-analyses concluded that saturated fat intake is not significantly associated with cardiovascular disease when considering replacement nutrients. Replacing saturated fat with refined carbohydrates (common in low-fat diets) does not improve cardiovascular outcomes. The quality of the overall diet matters more than butter consumption in isolation.
CLA and Metabolic Effects
Grass-fed butter contains 0.5-2g of CLA per 100g — a naturally occurring fatty acid with demonstrated anti-cancer properties, fat reduction, and lean mass preservation effects in research. CLA is produced by bacteria in the rumen of grass-fed ruminants and is substantially higher in butter from grass-fed vs grain-fed cows. Regular consumption of grass-fed butter is a practical way to increase dietary CLA intake.
