Soybean oil is considered bad for health primarily due to its high content of omega-6 fatty acids, especially linoleic acid. Excessive consumption of omega-6 fats, which dominate in soybean oil, can lead to an imbalanced omega-6 to omega-3 ratio, triggering chronic inflammation. This inflammation is linked to multiple health issues like heart disease, obesity, diabetes, liver diseases, and even some neurological conditions. Additionally, when soybean oil is heated, it produces oxidized lipids that contribute to artery hardening (atherosclerosis). Other concerns include:
- Increased risk of type II diabetes through effects like insulin resistance and high blood sugar.
- Contribution to nonalcoholic fatty liver disease (NAFLD).
- Adverse impact on the gut microbiome, increasing harmful bacteria and inflammation, potentially leading to inflammatory bowel diseases.
- Contains trans fats if partially hydrogenated, which are harmful to metabolism and heart health.
- Disruption of immune function and potential hormonal imbalances.
Due to these risks, it is recommended to limit intake of soybean oil and prefer oils with a better fatty acid balance, like those rich in omega-3s or monounsaturated fats.
