Cottonseed oil is a commonly used, low-carb, and high-fat vegetable oil derived from cotton seeds. It is often marketed as a healthy cooking oil and sanctioned by health experts. However, opinions vary on whether cottonseed oil is beneficial or detrimental to health. While some sources claim that it can reduce inflammation and lower cholesterol, others highlight the risk of heart disease associated with its high saturated fat content and the formation of oxidized lipids during cooking. As for its compatibility with the keto diet, cottonseed oil is considered unhealthy due to its highly refined nature and the presence of harmful chemicals. Keto dieters are advised to choose alternative oils like virgin olive oil, coconut oil, or avocado oil.

Cottonseed oil is highly refined, prone to oxidation, and may cause inflammation
Cottonseed oil is highly refined, making it prone to oxidation and potentially causing inflammation in the body. The refining process involves high heat and chemicals, which strip the oil of its nutrients and replace them with harmful substances. This oxidation changes the chemical composition of the oil, leading to potential health risks.
Cottonseed oil has a significant linoleic acid content, typically around 55%. When exposed to high temperatures during cooking, this acid is prone to oxidation. Oxidized lipids are detrimental to health and are linked to an increased risk of heart disease. Consuming oxidized oils can accelerate the progression of heart disease, as oxidized lipids contribute to higher levels of inflammation in the body.
While some sources claim that cottonseed oil may reduce inflammation, these claims are based on animal studies and observations from the Mediterranean diet. Cottonseed oil contains only 18% monounsaturated fat, which is lower than other oils recommended for their anti-inflammatory properties. Additionally, the high level of polyunsaturated fat in cottonseed oil can lower LDL ("bad" cholesterol) and increase HDL ("good" cholesterol), but it also contains saturated fat, which can increase the risk of heart disease.
As a highly refined oil, cottonseed oil is not recommended for a keto diet, even though it is low in net carbs and high in fat. Keto dieters are advised to obtain their fats from healthier sources, such as virgin olive oil, coconut oil, or avocado oil, to ensure their body burns clean fuel during ketosis. While cottonseed oil is commonly used in processed foods and baking due to its functional properties and ability to extend shelf life, it is not considered a healthy choice, especially when heated.

It's low in carbs and high in fat, but there are healthier keto-friendly alternatives
Cottonseed oil is a highly refined oil that is low in carbs and high in fat. One tablespoon (14 grams) of cottonseed oil contains 7 grams of polyunsaturated fat and 3.5 grams of saturated fat. While this fits the keto diet's macronutrient profile, there are healthier keto-friendly alternatives.
Cottonseed oil contains 55% linoleic acid, which will oxidize when exposed to high temperatures. This oxidation changes the chemical composition of the oil, generating oxidized lipids, which are linked to an increased risk of heart disease. Furthermore, the refining process strips the oil of nutrients and replaces them with harmful chemicals.
There are several healthier keto-friendly alternatives to cottonseed oil that can be used, such as virgin olive oil, coconut oil, or avocado oil. These oils provide a better source of healthy fats and do not pose the same risks of oxidation and inflammation as cottonseed oil.
While cottonseed oil may be low in carbs and high in fat, it is important to prioritize healthier fats in your keto diet. This will ensure that your body burns clean fuel while in ketosis and can help avoid potential health problems associated with "dirty keto".
In addition to the aforementioned alternatives, butter, MCT oil, and nut butter are also recommended as keto-approved fats that can improve the taste of your food.

It's a common vegetable oil used in processed foods and by fast-food chains
Cottonseed oil is a common vegetable oil used in processed foods and by fast-food chains. It is extracted from the seeds of cotton plants, mainly Gossypium hirsutum and Gossypium herbaceum, which are primarily grown for their cotton fibre and animal feed. Cottonseed oil is well-known for its use as a cooking oil and is also commonly used in packaged foods.
Cottonseed oil has a long history, dating back to the 19th century when it was first used in oil lamps and candles. It gained popularity in the 1820s and 1830s during Europe's fats and oils shortage, and American entrepreneurs began crushing cotton seeds to extract the oil. However, its use in fortifying animal fats and lards was later exposed as illegal, leading to import tariffs and bans. Despite this, cottonseed oil continued to be produced and used in various industries.
Today, cottonseed oil is commonly used in processed foods and by fast-food chains due to its ability to extend shelf life and enhance flavour. It is often used for frying, adding moisture to baked goods, and achieving a creamy consistency in whipped creams and icings. Cottonseed oil is also used in cosmetic products as a fragrance-free skin moisturiser and emollient.
While cottonseed oil is said to have some health benefits, such as its ability to reduce inflammation and lower the risk of heart disease when consumed in moderation, it is also high in saturated fat, which may increase the risk of heart disease. Additionally, the refining process of cottonseed oil can lead to oxidation, which is not considered beneficial for health.
When following a keto diet, it is generally recommended to avoid cottonseed oil due to its high refinement and potential for causing inflammation in the body. However, healthier alternatives such as virgin olive oil, coconut oil, or avocado oil are recommended to ensure the body burns clean fuel during ketosis.

It contains polyunsaturated fat, which can help lower bad LDL cholesterol
While cottonseed oil is low in net carbs, it is highly refined and prone to oxidation, which may cause inflammation in the body. This is because it contains high levels of linoleic acid, which can oxidize when exposed to high temperatures. As a result, many sources recommend avoiding cottonseed oil on a keto diet.
However, cottonseed oil does contain polyunsaturated fat, which can offer some health benefits. For example, it can help to lower bad LDL cholesterol and increase good HDL cholesterol. This can, in turn, improve blood pressure and reduce the risk of heart disease and stroke.
In a small 2018 study, healthy men had lower cholesterol and triglyceride levels after following a diet rich in cottonseed oil for 5 days. Additionally, research in animals has suggested that cottonseed oil may reduce inflammation. Specifically, rats injected with cottonseed oil had lower markers of inflammation after a stroke-like brain injury.
While the polyunsaturated fat content of cottonseed oil may offer some potential health benefits, it is important to consider the overall effects of the oil on the body. The high level of linoleic acid and the refining process that cottonseed oil undergoes can lead to oxidation, which is not beneficial for health. As such, it may be advisable to prioritize other keto-friendly oils, such as virgin olive oil, coconut oil, or avocado oil, that can provide similar health benefits without the potential drawbacks of cottonseed oil.

It's high in saturated fat, which may increase the risk of heart disease
Cottonseed oil is a highly refined oil that is derived from the seeds of cotton plants. It is commonly used in processed foods and by fast-food chains for deep frying. While it is low in net carbs, it is also high in saturated fat, which may increase the risk of heart disease.
A whole cotton seed contains about 15 to 20 percent oil. Of this, 3.5 grams is saturated fat, according to the American Heart Association, an acceptable amount in a vegetable oil. However, this type of fat has been found to have a negative effect on cholesterol levels, potentially increasing the risk of heart disease.
Research has shown that diets high in monounsaturated fats can reduce inflammation, which has been linked to chronic illnesses, including heart disease. However, cottonseed oil only contains 18 percent monounsaturated fat. While it also contains polyunsaturated fat, which can help lower "bad" cholesterol and increase "good" cholesterol, its high saturated fat content may outweigh these benefits.
Furthermore, cooking with cottonseed oil, a high-linoleic PUFA, can generate oxidized lipids, which have been linked to an accelerated progression of heart disease. This is because when an oil contains 55% linoleic acid, it will oxidize when exposed to high temperatures, changing the chemical composition and health effects of the oil.
As such, while cottonseed oil may be technically compliant with a keto diet due to its low carb content, its high saturated fat content and potential to form oxidized lipids may make it an unhealthy choice for those concerned about heart disease risk.
