Not all fats are created equal. Avocado for example is a superfood winner because it has monounsaturated fats and no cholesterol or sodium, while being packed in nutrients. Other healthy options include egg yolks, olives, nuts and seeds. The bottom line is that a balance of healthy fatty acids is essential to optimal health. When it comes to fats, avoid denatured and unstable fats and incorporate natural whole foods. Avoid vegetable oils used in deep frying; they’re often reheated and subject to becoming rancid. Hydrogenated fats such as certain margarines or shortening contain trans fatty acids, which research suggests raises your bad cholesterol (LDL) and lowers your good cholesterol (HDL).
