Olive Oil and Butter

Stick with olive oil and butter. Unlike highly processed items such as corn oil, canola oil, vegetable shortening and margarine, these natural foods contain no trans fats or foreign genetic material. Research shows that replacing harmful fats with unprocessed forms can reduce colon cancer risk by 25 percent or more, cut levels of artery plaque in half and correct cravings and insulin resistance in as little as two weeks.
