Canola Oil And Keto: A Bad Combination?

The keto diet is a low-carb, high-fat diet that can be challenging for beginners. While all plant-based oils are carb-free, not all are created equal. Canola oil, for instance, is not keto-friendly. Here are some reasons why:

- Canola oil can cause inflammation due to its higher omega-6 content compared to omega-3s, leading to an imbalance in the body and the production of pro-inflammatory chemicals.

- It is a genetically modified food, engineered to be more resistant to pests and herbicides, which can cause hormone disruption and soy allergies.

- It contains trans fats, which are known to raise bad cholesterol and lower good cholesterol.

- It lacks the health benefits of other oils like olive and coconut, which are rich in monounsaturated fats and antioxidants.

- It oxidizes easily, forming toxic compounds that can be absorbed into food and potentially causing degenerative illnesses.

- It has been linked to an increase in cellulite due to its ability to break down the collagen structure.

- It contains highly processed fats due to the extraction process, which can lead to inflammation and diseases in the long run.

Canola oil can cause inflammation due to its omega-6 content

Canola oil is a vegetable oil derived from the canola plant, which is a crossbreed of the rapeseed plant. It is a commonly used cooking oil due to its neutral flavour, smooth texture, and high smoke point. However, it has been linked to causing inflammation in the body due to its omega-6 content.

Inflammation is the body's natural response to injury or infection, but chronic inflammation can lead to serious diseases. Canola oil contains more omega-6 fatty acids than omega-3s, and an imbalance between these essential fatty acids can lead to increased inflammation. While omega-6 fatty acids are essential to health and perform important functions in the body, modern diets tend to be extremely high in omega-6s and low in omega-3s, causing an imbalance. This imbalance has been linked to various chronic conditions, including Alzheimer's disease, obesity, and heart disease.

The omega-6 to omega-3 ratio in canola oil is 2:1, which is higher than the ideal ratio of 1:1 for human health. Additionally, canola oil is highly refined, and the processing methods used to extract the oil can further reduce its nutritional value. The heating methods used during manufacturing, as well as high-heat cooking methods like frying, can negatively impact the omega-3 fatty acids in canola oil.

While canola oil does contain some beneficial nutrients, such as vitamins E and K, and monounsaturated and polyunsaturated fats, the high omega-6 content can contribute to inflammation if consumed in large amounts. Therefore, it is important to balance the consumption of canola oil with natural, whole-food sources of omega-3, such as fatty fish, walnuts, and flaxseed.

Canola oil is a genetically modified food

Canola oil is a popular and affordable oil, but it is not keto-friendly. One of the reasons for this is that canola oil is a genetically modified food.

Canola oil is made from canola seeds, which are produced using traditional breeding methods. The canola plant is a "distant younger cousin" of the rapeseed plant, which was originally grown to produce meal for cows in the latter half of the 20th century. Rapeseed plants naturally have high levels of eurcic acid, which is difficult for humans to digest. In the 1970s, scientists and farmers worked to produce a similar plant with much lower levels of eurcic acid, which could be consumed by people. This new plant was renamed canola oil, derived from the acronym CANadian Oil Low Acid.

In the 1990s, farmers began to use genetic modification to increase their yields. They took canola seeds and genetically modified them to make them resistant to herbicides. Soon, almost all of the canola in the US was genetically modified, and in recent years, over 96% of canola crops were GM. However, there are still non-GMO canola seeds available, which are used for non-GMO and organic canola oil production.

In Canada, almost all canola grown is genetically modified (approximately 95%). In 2020, Health Canada and the Canadian Food Inspection Agency approved a canola from the company Nuseed that is genetically engineered to have a modified fatty acid profile and to be tolerant of herbicides. This is the first GM crop approved with a "healthier oil" profile, but it is not yet available to consumers.

Canola oil contains trans fat

Canola oil is a popular and affordable oil used in homes, restaurants, and packaged foods worldwide. However, it is not recommended for a ketogenic diet due to its potential health risks. One of the main concerns is that canola oil contains trans fats, which are known to raise bad cholesterol and lower good cholesterol. While canola oil is marketed as having zero trans fats, studies have found that it can contain upwards of 4% trans fat content. This is because canola oil is typically partially hydrogenated, which creates trans fats in the final product. Additionally, the heating and processing of canola oil during production and cooking can lead to the formation of trans fats and other harmful breakdown products.

The presence of trans fats in canola oil is particularly concerning for those on a keto diet, as the diet should consist of approximately 70% healthy fats. While small amounts of natural trans fats can be found in products like cheese and butter, the synthetic trans fats in canola oil should be avoided or consumed minimally. Instead, keto dieters are advised to choose oils like sesame, avocado, coconut, and extra virgin olive oil, which are high in healthy monounsaturated fats.

Furthermore, canola oil has been linked to increased inflammation in the body due to its higher content of omega-6s compared to omega-3s. While omega-6s and omega-3s are both essential fatty acids, an imbalance between the two can lead to the production of pro-inflammatory chemicals. This can have negative health consequences, including increased blood pressure, blood clots, and chronic inflammation, which is a risk factor for serious diseases like diabetes and Alzheimer's.

In summary, the presence of trans fats and the potential for inflammation make canola oil a less ideal choice for those following a ketogenic diet. While canola oil may be convenient and affordable, there are healthier alternatives that better align with the keto diet's focus on consuming high-quality, healthy fats.

Canola oil lacks the health benefits of other oils

Canola oil is a vegetable-based oil derived from the canola plant, which is a genetically modified crop created through the crossbreeding of the rapeseed plant. While canola oil is often touted as one of the healthiest oils due to its low level of saturated fat, it lacks the health benefits offered by other oils such as olive oil and avocado oil.

Olive oil and avocado oil are considered better choices for those following a keto lifestyle as they are rich in monounsaturated fats and antioxidants. Additionally, research has not linked olive oil to an increase in weight, making it a healthier option for those looking to lose weight.

Canola oil, on the other hand, has a higher ratio of omega-6 to omega-3 fatty acids, which can lead to increased inflammation in the body. It also contains trans fats, which are known to raise bad cholesterol and lower good cholesterol. Furthermore, the process of extracting canola oil involves the use of synthetic chemicals, resulting in highly processed fats that can lead to inflammation and diseases in the long run.

While canola oil may provide some health benefits, such as improving insulin sensitivity and reducing total cholesterol and low-density lipoprotein cholesterol, it does not offer the same extensive health benefits as other oils recommended for the keto diet.

Canola oil oxidises easily

Canola oil is not recommended for the keto diet because it oxidises easily. When a cooking oil is exposed to heat, light, and oxygen, it can oxidise and produce harmful compounds and toxic by-products. Canola oil is particularly susceptible to oxidation because it is high in polyunsaturated fats, which have two or more carbon-to-carbon double bonds that are vulnerable to breaking down.

The oxidative stability of an oil is measured by its induction time, which is the point at which an oil breaks down and potentially produces harmful compounds. Canola oil has a short induction time, meaning it will oxidise easily.

Extra virgin olive oil, on the other hand, has been found to be the most resistant to oxidation when used in frying and cooking tests. It also has a high oxidative stability due to its high percentage of monounsaturated fat. This means that it takes longer for extra virgin olive oil to produce toxic compounds, and it produces them at a lower concentration.

In addition to its tendency to oxidise, canola oil also has other drawbacks that make it less suitable for the keto diet. It has been linked to inflammation, as it contains more omega-6s than omega-3s, and it is a genetically modified food, which some people on the keto diet try to avoid. It also contains trans fats, which can raise bad cholesterol and lower good cholesterol.
