Butter's surprising comeback: How moderation fits into a heart-healthy diet

Butter has long been a staple in kitchens, prized for its rich flavour and cooking versatility. Over the past two decades, scientific views on its health effects have shifted, moving away from strict warnings to a more balanced perspective. Experts now agree that while butter should be eaten in moderation, it can still be part of a healthy diet.

Butter is made mostly of milk fat, which gives food a satisfying taste and helps people feel full. A single tablespoon contains around 100 calories, almost all from fat, and about seven grams of saturated fat. Too much saturated fat has been linked to higher LDL cholesterol, a risk factor for heart disease.

For years, health organisations like the American Heart Association advised cutting back on butter due to its saturated fat content. But recent research, including large studies from 2010 and 2015, found no strong evidence tying saturated fats directly to heart problems. By 2017, the AHA updated its guidelines, focusing more on overall diet quality rather than singling out specific foods.

Despite its high fat content, butter does provide some nutrients. It contains small amounts of vitamins A, D, E, and K. Vitamin A supports vision, immune function, and cell growth, while vitamin D helps the body absorb calcium and maintain strong bones. Vitamin E acts as an antioxidant, protecting cells from damage, and vitamin K aids in regulating calcium in bones and blood vessels. The fat in butter also helps the body absorb these fat-soluble vitamins more effectively.

Nutritionists now suggest that one to two teaspoons of butter a day can fit into a balanced diet. The key is moderation, as excessive intake may still pose risks.

Current advice no longer treats butter as a food to avoid entirely. Instead, experts recommend enjoying it in small amounts as part of a varied diet. With its mix of fats and nutrients, butter can contribute to meals without significantly harming health when consumed responsibly.
