1. Olive Oil
There’s seemingly no end to the health benefits of olive oil. It’s good for your heart and high in healthy monounsaturated fats, and it just tastes good. But the healthiest high-quality, extra-virgin olive oils don’t handle heat well, so reserve them for salad dressings, says Trevor Holly Cates, N.D., a naturopathic physician with a practice in the Golden Door Spa at the Waldorf Astoria in Park City, Utah, and a board member of the American Association of Naturopathic Physicians. Lower-quality refined olive oils that can withstand high heats (sometimes labeled “pure” or “extra light”) have been heavily processed using heat and chemicals, and contain as much as three times less of the polyphenols and antioxidants that make extra-virgin olive oil so healthy.
