Certain oils and types of fish contain polyunsaturated fats, including soybean and corn oils and salmon and trout. Polyunsaturated fats are generally considered a good type of fat and can be used as healthier replacements to trans and saturated fats.
Polyunsaturated fats can be an important source of omega-3, omega-6 and vitamin E. They are also shown to reduce cholesterol levels and decrease the chances of heart disease. Easy ways to add more polyunsaturated fats into the diet include cooking with olive oil, eating fish once a week and snacking on sunflower seeds or walnuts. Polyunsaturated fats still have the same calories per gram as other fats, making it important to eat them in moderation as part of a healthy well-rounded diet.
