A health news website has an opinion piece written by a nutritionist. He attempts to debunk the myth that vegetable oils are good for people. He contends that they are not. He says these oils are often processed polyunsaturated fats, which become dangerous when exposed to heat and light. These fats can cause problems in the body. He recommends saturated fats as they are more stable. He recommends using coconut oil, olive oil, or just plain butter.
