What fat-containing foods should be consumed as sources of "healthy" fats and what foods should be limited because they are sources of less healthy fats? Does eating only "low-fat" foods ensure that one's diet is healthy?
Healthy fats would include those from nuts (walnuts), seeds, and certain oils such as soybean, safflower, corn, flaxseed, olive, or canola oils. Less healthy fats would be those that are saturated (from animal products), tropical oils (palm or coconut), and partially-hydrogenated fat (trans fatty acids). Low-fat foods may be a better choice for cardiovascular health, but they are not "calorie-free" and so must be consumed with portion control in mind.
