List of Seed Oils to Avoid: The Notorious Few

Some seed oils have been flagged for potential health risks. We’ll list these oils and explain why they might not be the best choice for your health:

  1. Canola Oil
  2. Soybean Oil
  3. Corn Oil
  4. Cottonseed Oil
  5. Sunflower Oil
  6. Safflower Oil
  7. Grapeseed Oil
  8. Rice Bran Oil
  9. Sesame Oil
  10. Peanut Oil

Here is the brief Explanation of the Seed Oils to Avoid:

Canola Oil:

Often marketed as a healthy oil due to its low saturated fat content, canola oil is highly processed and may contain trans fats due to the high-heat extraction process. It also has a high omega-6 to omega-3 fatty acid ratio, which can contribute to inflammation in the body.

Soybean Oil:

Like canola oil, soybean oil is high in omega-6 fatty acids, which can promote inflammation. It is also commonly derived from genetically modified (GM) soybeans, raising concerns about potential health effects of GMOs.

Corn Oil:

Corn oil is another oil that is high in omega-6 fatty acids and often made from genetically modified corn. Its high omega-6 content can contribute to an imbalance in fatty acids in the body and promote inflammatory processes.

Cottonseed Oil:

This oil is a byproduct of cotton farming and is often heavily processed. It may contain traces of pesticides and is high in saturated fat, which can be detrimental to heart health.

Sunflower Oil:

While there are varieties of sunflower oil that are high in healthy monounsaturated fats, many commercially available sunflower oils are high in omega-6 fatty acids and low in omega-3s, contributing to an unhealthy balance of fatty acids in the body.

Safflower Oil:

Similar to sunflower oil, safflower oil can be high in omega-6 fatty acids, depending on the type. High-oleic safflower oil is better but still should be consumed in moderation.

Grapeseed Oil:

Grapeseed oil has a high content of polyunsaturated fats, which can be unstable at high temperatures, leading to the production of harmful compounds when used for frying or cooking at high heat.

Rice Bran Oil:

Although it’s often touted for its high smoke point, rice bran oil can also be high in omega-6 fatty acids. Additionally, it may contain traces of arsenic, which is a concern for some consumers.

Sesame Oil:

While it has some health benefits and is popular in Asian cooking, sesame oil is also high in omega-6 fatty acids. It should be used in moderation, especially for those trying to reduce their intake of these fatty acids.

Peanut Oil:

Peanut oil is high in omega-6 fatty acids and may pose an allergen risk for people with peanut allergies. It is also often used in deep frying, which can result in the production of unhealthy trans fats.

How to Sidestep Seed Oils in Your Diet

Avoiding seed oils in your diet requires a bit of diligence, especially since they are so prevalent in processed foods. Here are some practical tips to help you identify and avoid them while grocery shopping:

  1. Read Labels Carefully: The first and most obvious step is to become an avid label reader. Check the ingredients list on packaged foods for any of the seed oils mentioned earlier. Remember that they might be listed under different names (e.g., “vegetable oil” could be soybean, corn, or canola oil).
  2. Choose Whole, Unprocessed Foods: One of the best ways to avoid seed oils is to eat whole, unprocessed foods. Fresh fruits, vegetables, lean meats, fish, nuts, and seeds typically do not contain added oils.
  3. Opt for Healthy Oil Alternatives: When cooking or preparing food at home, choose healthier oils like olive oil, avocado oil, or coconut oil. These oils have better nutritional profiles and are less processed.
  4. Be Cautious of Restaurant Food: Many restaurants cook with seed oils due to their low cost and high smoke point. When dining out, you can ask what type of oil is used in the preparation of your meal.
  5. Prepare Homemade Versions of Packaged Foods: A lot of packaged foods, like salad dressings and mayonnaise, contain seed oils. Preparing these items at home allows you to control the ingredients and opt for healthier oils.


In conclusion, while seed oils are common in many diets, there are valid reasons to consider reducing or eliminating them from your meals. By opting for healthier alternatives and being mindful of what you consume, you can make better choices for your long-term health and well-being.
