Canola Oil

Dirty Keto Ingredient

What is Canola Oil?

The canola seed comes from a modified rapeseed plant (Brassica napus), but there are other varieties of the Brassica family (B. rapa and B. juncea). These special seeds were achieved through crossbreeding in the 1960s in an effort to make rapeseed oil safer for human consumption. This oil is highly processed and requires synthetic antioxidants to prevent it from going rancid too quickly.

Keto Status?



Canola oxidizes easily. Oxidation is another term for “going bad.” The monounsaturated fats make it unstable and more prone to oxidation. This means that the oil is more sensitive to light, oxygen, and high temperatures than saturated oils. That’s why it’s necessary to add synthetic antioxidants that increase shelf life, such as TBHQ, BHA, and BHT, all of which are potentially dangerous. Without this step, canola oil would quickly turn rancid when cooked over high heat. Thanks to these antioxidants, it also acquires a high smoking point of 400°F (204°C). In comparison, coconut and MCT Oil don’t need artificial antioxidants because the saturated fats give them a naturally long shelf life and a high smoke point. Their smoke points are 350°F and 320°F, respectively. It also contains a high ratio of Omega-6 to Omega 3 Fatty Acids.

Possible Side Effects From Ingesting Canola Oil?

Omega 6 causes chronic inflammation, cognitive dysfunction, & insulin resistance. It also damages blood vessel function and worsens hypertension.

I Heart Keto Mart Rating Guide

I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly
