Seed oils have been a staple in kitchens for years, but recently, they have come under fire. Once thought to be a healthy option, these oils are now accused of being toxic, unnatural, and even causing health problems. But is this true? Let’s look at the facts.
What Are Seed Oils?
Seed oils come from plants like sunflower, soybean, canola, and corn. They are refined through a process that involves chemicals like hexane. This method raises concern for some people, but experts say the oils are safe to eat. In fact, the final product is carefully processed to remove harmful substances.
Professor Tom Sanders from King’s College London explains that refining removes things that could be harmful. Sarah Berry, another expert in nutrition, agrees. She says the oils are safe for our health after they are refined.
Are Seed Oils Dangerous?
One of the main concerns people have is the omega-6 fats found in seed oils. These fats, especially linoleic acid, are said to cause inflammation in the body. Some worry that eating too much omega-6 could lead to health problems like heart disease.
However, many experts say this claim is not supported by real science. Berry points out that while omega-6 and omega-3 fats share some enzymes in our body, this does not cause harm. Research shows that linoleic acid can be neutral or even help reduce inflammation.
“Linoleic acid is an essential nutrient,” says Sanders. He explains that our bodies need this fat to stay healthy. Without enough of it, we could have problems with our immune system and blood flow.
The Health Benefits of Seed Oils
In fact, seed oils can have some health benefits. They are known to help lower cholesterol. Studies have shown that switching from butter to seed oils can reduce the risk of heart disease and cancer.
A large study of 200,000 people found that replacing butter with seed oils like soybean or canola lowered the risk of death by 17%. The researchers also saw a decrease in heart disease and cancer. This shows that seed oils can be a healthy choice when used in place of unhealthy fats.
Why the Confusion?
Some of the confusion about seed oils may come from older research. Years ago, people often ate seed oils through margarine. But margarine at that time contained harmful trans fats. Today, we know trans fats are bad for health. However, seed oils themselves, when used properly, are safe.
Berry reminds us that just because we see a rise in certain diseases doesn’t mean seed oils are to blame. The way we eat has changed over time. Most seed oils are now found in ultra-processed foods, which are full of other unhealthy ingredients. It’s not just the oils that are a problem—it’s the overall quality of the food we eat.
Misinformation Spreads Fast
Despite the facts, misinformation about seed oils continues to spread. Berry faced backlash after defending seed oils in a podcast. She received hate mail from people who believed she was promoting harmful oils. “They want to silence the science,” Berry says. This only made her more determined to speak out.
Both Berry and Sanders believe the panic about seed oils is based on gossip, not real science. They say the key to a healthy diet is not avoiding one ingredient but focusing on balance and variety.
What Should You Do?
Don’t fear seed oils. They are not as harmful as some people claim. Instead, focus on eating a balanced diet that includes whole foods. Avoid ultra-processed foods that are high in unhealthy fats, sugars, and artificial ingredients. The goal is to make healthy choices every day.
In conclusion, seed oils are safe when used properly. They have health benefits, like lowering cholesterol and reducing the risk of heart disease. There is no reason to panic about them. Instead, focus on eating a well-rounded diet with a variety of nutrients.
