Which Cooking Oil is the Best One for You?

Fitday Editor

A plethora of scientific research has proven that when it comes to health we need to make sure we consume enough healthy fats. However, more important than total fat is the type of fat in our diets. We all know that oils are much healthier than fats that come from animals (with the exception of coconut, palm kernel, and palm oils), particularly in relation to heart and brain health. Fats that come from animals have a much higher amount of saturated fat--the type of fat correlated with increased total cholesterol and LDL cholesterol, type 2 diabetes, and cardiovascular disease. But with so many different oils out there, how do you know which one is best for you?

All vegetable oils have a different nutrient content and specific uses in cooking. Although cooking oils are very similar in their calorie content, the nutrient content varies quite significantly from one oil to the next. All oils contain varying amounts of saturated fat, monounsaturated fat, and polyunsaturated fat. Additionally, oils have different uses in the kitchen.

Many of us are getting too many omega-6 fatty acids and not enough omega-3 fatty acids, throwing the ratio of the two off. It's recommended we increase our intake of monounsaturated fats in whole foods, such as olive oil and canola oil, while minimizing our intake of corn, soybean, and safflower oils, which are high in omega-6 fats.
