Today we’re going to talk about good fats vs. bad fats. 

Bad fats:

• Soy oil 

• Corn oil

• Canola oil 

• Cottonseed oil 

• Margarine 

The above oils are GMO and inflammatory. There is a solvent sometimes used when processing these oils that is potentially toxic. There could also be traces of glyphosate (an herbicide in these oils. These oils are in many different foods, including common foods like mayonnaise, salad dressing, and hummus. Margarine has trans fats. Trans fats are deadly. 

These bad fats are also loaded with omega 6 fatty acids. In many cases, fast food restaurants and other restaurants include these bad fats in their foods. 

There are a few types of oils that are fine for some people to consume in small amounts every now and then, as long as they’re cold-pressed and organic. Flax oil is very estrogenic and may only be beneficial for females who are lacking estrogen and need a small boost over a short period of time. 

These oils include:

• Safflower oil 

• Sunflower oil 

• Flax oil

• Sesame seed oil (and tahini)

• Nut oils 

Good fats:

• Cod liver oil

• Camel fat 

• Butter (grass-fed, organic, and raw if possible)
