Turns Out Butter Isn't Bad
A recent study—conducted by scientists from Tufts University and published in PLOS ONE—found only a "weak association" between eating butter and overall mortality. The study also showed no link between butter consumption and an increased risk for heart disease, and a slightly protective effect against diabetes.
Researchers analyzed data from 9 studies and combined the information. One tablespoon of butter was the standard serving size, and average daily butter consumption ranged from about 1/3 of a serving size to 3.2 serving sizes. Each serving of butter showed an "insignificant" association with overall mortality and health problems like cardiovascular disease and diabetes.
People who consumed the most butter had worse diets overall that those who consumed the least. According to researchers, butter is a healthier food choice than sugar and starches, and likely a less healthy option than spreads and oils that contain "good"—monounsaturated and polyunsaturated—fats.
