Butter is a dairy product made from the fat of milk, and it is a rich source of various nutrients. The nutritional content of butter can vary depending on the type of milk used to produce it and the level of processing it undergoes. However, on average, one tablespoon of butter (approximately 14 grams) contains a significant amount of calories, fat, and other essential nutrients.

Macronutrient Composition
The macronutrient composition of one tablespoon of butter is characterized by a high fat content, with minimal amounts of carbohydrates and protein. The saturated fat content of butter is a significant contributor to its high calorie density, with approximately 7.3 grams of saturated fat per tablespoon. The monounsaturated and polyunsaturated fat content of butter is relatively lower, with 2.9 grams and 0.4 grams per tablespoon, respectively.
Health Implications of Butter Consumption
The health implications of butter consumption are a topic of ongoing debate, with some studies suggesting that moderate consumption of butter may have neutral or even beneficial effects on cardiovascular health. However, other studies have found that high consumption of butter is associated with an increased risk of cardiovascular disease, primarily due to its high saturated fat content. A systematic review of 15 prospective cohort studies found that high consumption of butter was associated with an increased risk of cardiovascular disease, with a relative risk of 1.12 (95% CI: 1.04-1.21) per 14-gram serving per day.
Nutrient Interactions and Bioavailability
The nutrient interactions and bioavailability of butter are complex and influenced by various factors, including the type of milk used to produce it and the level of processing it undergoes. The fat-soluble vitamins in butter, including vitamins A, D, E, and K, are highly bioavailable and can be easily absorbed by the body. However, the mineral content of butter is relatively low, with minimal amounts of calcium, iron, and potassium.
What is the recommended daily intake of butter?
+The recommended daily intake of butter varies depending on factors such as age, sex, and overall health status. The American Heart Association recommends limiting daily intake of saturated fats, including those found in butter, to no more than 5-6% of total daily calories. Based on this recommendation, the daily intake of butter should be limited to approximately 1-2 tablespoons per day.
Can butter be part of a healthy diet?
+Yes, butter can be part of a healthy diet when consumed in moderation. The key is to balance butter consumption with other nutrient-dense foods, including fruits, vegetables, whole grains, and lean protein sources. It is also essential to choose high-quality butter from grass-fed cows or other pasture-raised animals, as these products tend to have a more favorable fatty acid profile and higher levels of fat-soluble vitamins.
