Do Seed Oils Deserve the Backlash?

Vegetable oils are being targeted by Robert F. Kennedy Jr. and some influencers who claim they are linked to chronic disease and other health problems. However, many health experts say the oils themselves are not the main problem; rather, the issue is the American diet and excessive consumption of processed foods.

Why it matters: The debate over vegetable oils is ultimately connected to Americans’ heavy reliance on processed foods and broader dietary habits that many believe require government action.

What is happening: Online influencers and the health movement led by RFK share skepticism about vegetable oils and their effect on public health.

• Oils made from seeds such as canola, soybean, and sunflower have been labeled by critics as the “hateful eight.”
• RFK has claimed that Americans are being unknowingly poisoned by these oils and has argued that beef tallow is a healthier option.
• Author Nina Teicholz recently wrote that addressing the chronic disease crisis should start with a comprehensive, science-based review of vegetable oils.

However, many nutrition experts say concerns about vegetable oils are exaggerated, lack context, or are not supported by science. Studies have repeatedly found that they are safe to consume and may be associated with lower risks of cardiovascular disease, cancer, and type 2 diabetes.

• Nutrition experts also note that vegetable oils are generally healthier than other sources of fat such as butter and lard.
• Vegetable oils consist mainly of unsaturated fats and are rich in omega-6 fatty acids, which can support heart health, while containing relatively low levels of omega-3.
• Registered dietitian Judy Simon told Verywell Health that many ultra-processed foods are less nutrient-dense, but the oil itself has been heavily demonized.

Latest developments: A recent study found that ultra-processed foods high in vegetable oils may increase the risk of colon cancer, which is rising among younger people.

• Excessive consumption of omega-6 fatty acids in ultra-processed foods may be part of the issue.
• Vegetable oils are used in many packaged and processed foods.
• The issue is not that omega-6 is inherently harmful, but that Americans tend to consume it in excessive amounts.

What experts say: Although vegetable oils themselves are often processed, the bigger concern is that they are commonly used to make ultra-processed foods such as fast-food burgers, fries, packaged snacks, and fairground foods.

Bottom line: Using vegetable oils in moderation when cooking healthy meals at home may be perfectly acceptable. The broader message is that frequent consumption of fast food and ultra-processed foods is the more important problem.
