There is may mayonnaise in the grocery store. It might be confusing which to pick or choose. Look at the ingredients at the back of the jar. 

Ingredients such as preservatives, sugars, or food starches like corn flour. These ingredients you should avoid because they are not keto-friendly and would put your body out of ketosis. 

Are there oils better for keto diet followers?

There are few oils used in the making of mayonnaise; some are better than others. 

Olive oil is a healthy type of oil containing healthy fat. It is rich in monounsaturated oleic acid which reduces inflammation. 

Olive oil is good for your heart health as well as reducing the risk of some chronic conditions such as Alzheimer’s disease and type 2 diabetes.

Avocado oil contains oleic acid, which is a monounsaturated omega-9 fatty acid. It also contains omega 3 and omega 6 fatty acids. 

Reducing the risk for chronic diseases such as dementia. It also improves the lipid profile by reducing LDL (bad cholesterol) and triglycerides and total cholesterol. It also boosts up the good cholesterol HDL cholesterol. 

It is an antioxidant as well. It contains Vitamin A and Vitamin E which have a major role in healing wounds and skin health.

MCT oil is known as medium chain triglyceride.  It was shown to help in weight loss and fat burning which works hand in hand with the keto diet’s purpose of losing fat. It is good for heart health in general.

Coconut oil contains MCT as well which provides you with energy, a quick source of energy might I add. It also reduces hunger, thus you eat less during the day.

High-oleic sunflower or high-oleic safflower oil lowers cholesterol level and improves heart health. It reduces inflammation.  The good news is that you can also tolerate high temperatures to be used for cooking.

What oils to avoid while on the keto diet?

There are some oils that you should avoid while being on the keto diet. Some of these oils include soybean oil, canola oil, corn oil, regular safflower oil, cottonseed oil, and grapeseed oil.

  • Soybean and corn oil both contain polyunsaturated fatty acids that would cause inflammation. While canola oil contains trans fats and is processed. 
  • Cottonseed oil contains unstable polyunsaturated fatty acids that would oxidize. On top of that, they contain toxins.

It is better to stay away from these oils when choosing your mayonnaise. Despite not containing carbs, they are not good for your health.
