Industrial seed oils have been getting more attention as the newest addition to diets across the world. However, amid the growing use of industrial seed oils is the lack of information about how these products affect the body.
Many people tend to believe it is a safe ingredient. But some research suggested such oils are actually not healthy and are making people sick, according to Chris Kresser, co-director of the California Center for Functional Medicine and author of Unconventional Medicine.
Industrial seed oils are highly processed oils extracted from soybeans, corn, rapeseed, cottonseed and safflower seeds. Compared to traditional fats such as olive oil, coconut oil, butter, ghee and lard, “a growing body of research indicates that the consumption of industrial seed oils has significant adverse effects on our health,” Kresser said.
Why Industrial Seed Oils Are Bad For You
1. Highly unstable products
Industrial seed oils contain polyunsaturated fatty acids that are highly unstable, which oxidize easily upon exposure to heat, light and chemical inputs. When exposed to the said factors, the oil could create the harmful substances, trans fats and lipid peroxides.
Trans fats contribute to development of cardiovascular disease and type 2 diabetes, while lipid peroxides in the body accelerates aging and development of chronic diseases.
2. Imbalanced omega-6 to omega-3
Consumption of industrial seed oils could cause imbalanced omega-6- to omega-3 ratio in the body, which could increase the risk of having chronic inflammatory diseases.
The balance between omega-6 and omega-3 fatty acids must be one to one. However, diets with industrial seed oils could affect this balance and cause omega-6 to omega-3 ratios to be in the range of 10 to one or 20 to one.
3. Genetically modified plants
Industrial seed oils are from genetically modified plants, such as corn, soy, cotton and rapeseed. Some studies showed that long-term consumption of genetically modified or processed food could damage the body and increase the risk of cancer.
4. The use of additives
Manufacturers use synthetic antioxidants in industrial seed oils to prevent oxidation and rancidity. But the additives, such as BHA, BHT and TBHQ, have been linked to development of food allergies.
5. Extra toxic
From manufacturers to restaurants and homes, industrial seed oils are repeatedly heated, which further boosts the product’s harmful effects. Reusing the oils over and over could lead to production of toxic byproducts that may damage DNA and cause high blood pressure, heart disease and intestinal and liver damage.
“Contrary to what many health organizations have been telling us for years, industrial seed oils are not healthy foods,” Kresser said. Their consumption is associated with a variety of health problems, including asthma, autoimmune disease, cognition and mental health, diabetes, obesity, heart disease, infertility, macular degeneration and osteoarthritis.
