Avoid processed dietary oils

It’s said that we should avoid processed foods, instead opting for healthy, “clean” options that are straight from nature – fresh fruits and vegetables, complex grains and carbohydrates, and lean meats such as chicken and beef. Rarely, however, do we hear about cooking oils – but a new study has changed that.

Austrian researchers found that consuming processed cooking oils such as linoleic acid not only promotes inflammation throughout your body but also prevents the death of cancer cells in your liver, contributing to your risk of getting liver cancer. Cooking with processed oils at high heat also increases their potential side effects.


If you’re going to use oil when you cook, skip the processed junk. Instead, use small amounts of olive or coconut oil on low heat. By doing this, you’ll not only eliminate excess calories that make you fat but also eliminate side effects and possibly save your liver from inflammation and cancer.
