You may have heard the claim that vegetable oils are a “healthier” option, but did you know that consuming certain vegetable oils can actually wreak havoc on your health? Specifically, corn oil has been found to damage the digestive tract, leading to bowel problems and potentially, cancer. In this article, we will explore the detrimental effects of corn oil, and why you may want to think twice before incorporating it in your diet.
The Trouble with Corn Oil
Corn oil is not really a vegetable oil, as corn is a grain, not a vegetable. Regardless, many of us consume foods cooked in corn oil, thanks to its widespread use in restaurants and processed foods. The issue with corn oil is that it is high in omega-6 fatty acids, which can cause inflammation in the gut. Moreover, people with gluten sensitivities may be especially vulnerable.
Lab Research
Recent lab research conducted in Japan discovered that corn oil can cause inflammation in the gut, which eventually leads to bowel problems. Researchers found that corn oil not only increased villous atrophy (the shrinking and flattening of the finger-like projections in the small intestine, known as villi), but it also led to an increased production of inflammatory chemicals. The Gluten Free Society’s report on this research particularly warns people with gluten sensitivities about the dangers of consuming corn oil.
The Role of Omega-6 Fatty Acids
One of the suspected causes of corn oil’s damaging effects on the gut is its high level of omega-6 fatty acids. Although some level of omega-6 fatty acids is essential as they contribute to brain function and normal growth and development, the standard American diet has an imbalanced ratio of omega-6 to omega-3 fatty acids. Ideally, this ratio should be around 1:1 or 2:1, but in reality, it’s closer to 20:1.
This high ratio of omega-6 to omega-3 fatty acids can lead to an overproduction of pro-inflammatory chemicals, which in turn can result in inflammation and increase the risk of various health problems, including heart disease, cancer, and autoimmune diseases.
The Risk of GMOs
Another factor that contributes to the potential harm of corn oil is its possible GMO (genetically modified organisms) content. A significant portion of corn grown in the United States is genetically modified, which means that the oil extracted from it may be contaminated with GMOs. There is ongoing debate about the safety and health implications of GMOs, but some studies have linked them to an increased risk of digestive tract issues, as well as allergies and immune system problems.
Other Harmful Vegetable Oils
Aside from corn oil, there are other vegetable oils that can also have detrimental effects on your health. Like corn oil, soybean oil is high in omega-6 fatty acids and is often derived from GMO crops. Additionally, vegetable oils such as canola, grapeseed, and sunflower also contain high levels of omega-6 fatty acids. These oils are commonly used in restaurants and processed food products, posing the same risks to your gut health as corn oil.
Healthier Oil Alternatives
Now that we have discussed the damaging effects of corn oil, it’s important to know about healthier alternatives.
- Olive oil: Rich in heart-healthy monounsaturated fats and antioxidants, olive oil is an excellent choice for cooking and salad dressings.
- Coconut oil: Although high in saturated fats, coconut oil’s medium-chain triglycerides offer numerous health benefits, including improved brain function and potential weight loss support.
- Avocado oil: Another oil high in monounsaturated fats, avocado oil boasts an impressive nutrient profile and is suitable for high-heat cooking.
- Flaxseed oil: This oil is high in omega-3 fatty acids, which can help lower inflammation and balance out the ratio of omega-6 to omega-3 in your diet.
In Conclusion
Choosing the right cooking oil is important to your gut health and overall well-being. Corn oil, along with other harmful vegetable oils, may be a common choice in restaurants and processed foods, but its high omega-6 fatty acid content and potential for GMO contamination make it a poor choice for long-term health. By opting for healthier oil alternatives such as olive, coconut, avocado, or flaxseed oil, you can make a positive impact on your gut health and overall well-being.
