Are seed oils good or bad for you; pros and cons explained

RFK Jr., Donald Trump’s pick to head the US Health and Human Services Department, feels Americans are being 'unknowingly poisoned' by seed oils. The pros and cons of seed oils often make for heated discussions on social media. Some call it inflammatory due to high levels of Omega-6 in it, others hail its high vitamin E and healthy fat content. Is seed oil healthy or harmful? Let's understand their benefits and side effects.

What are seed oils

Seed oils are cooking oils that are extracted from the seeds of various plants either by chemical or mechanical process. They are commonly known as vegetable oils. Some of the common seed oils include canola (rapeseed) oil, corn oil, cottonseed oil, soybean oil, and sunflower oil.

Seed oils, especially those like sunflower, safflower, and canola, are rich in polyunsaturated fats, including omega-3 and omega-6 fatty acids. These fats are heart-healthy and support brain function, and the maintenance of healthy cell membranes. Omega-3 fatty acids, in particular, have been linked to reduced inflammation and a lower risk of heart disease.

They also contain vitamin E, an antioxidant that plays a crucial role in protecting the body from oxidative stress. This vitamin helps protect cells from damage, supports the immune system, and contributes to healthy skin. Certain seed oils, like flaxseed and chia seed oil, are rich in omega-3 fatty acids, which can help reduce cholesterol levels and lower blood pressure.

Side effects

One of the main concerns with seed oils is their high omega-6 fatty acid content. While omega-6 is essential fats the body needs, they are often consumed in excess in modern diets. The imbalance between omega-6 and omega-3 fatty acids can contribute to chronic inflammation. Chronic inflammation can in turn lead to heart conditions, arthritis, metabolic syndrome, stroke or cancer.

Another concern with seed oils is that they are highly refined and processed with bleaching, deodorizing, and heating, which can lead to creation of harmful compounds. When heated at high temperatures and used in deep-frying or cooking at high heat, they may undergo oxidation, producing potentially toxic byproducts like aldehydes. This is the reason junk food cooked in these oils can wreak havoc with our body.

These toxic compounds can damage tissues and contribute to aging and chronic diseases, increase risk of cancer, and lead to insulin resistance. Besides, the refining process can also increase trans fat content which can lead to heart disease, high cholesterol and high blood pressure. It can also lead to weight loss.When these seed oils are mechanically extracted through cold pressing or expeller pressing of the plant seeds, they not only retain nutrients, but also lower cholesterol, and free from harmful chemicals and additives.Cold-pressed oils are high in essential fatty acids, antioxidants, vitamin E, vitamin K, vitamin C, and other healthy fats. They are considered safe and healthy for people with chronic disorders like heart disease and high cholesterol.
