Expand your healthy cooking oil choices

The healthiest fats for cooking and using on food come from plants. Plant oils consist mostly of unsaturated fat, which in limited amounts is good for the heart. One can enjoy a wide variety of plant oils, such as avocado, canola, corn, flaxseed, grapeseed, olive, peanut, rice bran, safflower, soybean, sunflower, and walnut oils. But high heat can break down plant oil molecules and reduce health benefits. The most fragile plant oils include extra-virgin olive oil and nut oils, such as walnut oil.
