As most of us know by now, not all fats are created equal. In moderation, some fats have real health benefits. Mono-unsaturated fats, like those in almond oil, olive oil and (to a lesser extent) flaxseed oil, fight cholesterol and protect the heart. And they have other advantages, says nutritionist Lisa Sasson of New York University. Almond oil is a good source of vitamin E, flaxseed oil of heart-protective omega-3 fatty acids. Olive oil is still the most lauded; its antioxidants may protect against certain cancers.
