Read the research on Omega-6 fatty acids
Cardiovascular disease- Researchers evaluated unpublished data from the Minnesota Coronary Experiment (1968-1973) and found that while replacing saturated fat with polyunsaturated fat lowered blood cholesterol levels, it did not translate to lower risk of death from coronary heart disease. Rather, in adults over 65, a decrease in blood cholesterol led to 35% higher risk of all cause mortality.
- High Omega-6 intake, or a high Omega-6 to Omega-3 ratio, are associated with weight gain and insulin resistance, in both human and animal studies.
- Dietary consumption of fats lopsided on linoleic acid (an Omega-6) during pregnancy in mice increases overeating in offspring. In another mouse model, consuming a high-fat diet with high levels of linoleic acid from gestational periods through adulthood led to more severe obesity than consuming a high-fat diet with low linoleic acid.
- Young people with a high ratio of Omega-6 to Omega-3 exhibited higher rates of mood disorders and depression.
- Decreased sperm quantity, quality and mobility: “A high proportion of Omega-6 FAs in the spermatozoa is a distinctive feature of infertile men.”
- Men who consumed more Omega-6s were found to have lower testicular volume.
- Omega-6 PUFA levels were almost double in bones with osteoporosis and participants with higher levels of Arachidonic acid (linoleic acid is a precursor) tended to have higher inflamed joint severity.
- High levels of soybean oil can promote the body’s inflammatory response. High inflammation can lead to a series of chronic diseases, such as atherosclerosis, rheumatoid arthritis and insulin resistance.
- Higher Omega-6 consumption was associated with higher chances of severe asthma in children, when compared to Omega-3s.
- In a mouse model, “chronic administration of a diet enriched with canola oil results in significant deficits of working memory and synaptic pathology…”
