Once again, marketing is responsible for the great misconceptions about margarine. It is not healthy. It is one of the least healthy foods in the diet. So get rid of it! Margarine is a miserable version of butter, made from hydrogenated vegetable oils, and it’s more unnatural than you think. It’s pure chemistry. What’s wrong with it? Trans fats can damage the heart and blood vessels and alter cholesterol levels. Switch to butter as a healthier alternative. Other healthy alternatives are olive oil and avocado oil, which you can spread on bread. But please avoid margarine!
