Eating snacks with 30g of soybean oil every day for a month doesn’t make your body more inflamed or damage your blood fats, even though some people say it does.
After eating soybean oil daily for a month, the level of a fatty acid called arachidonic acid went down in red blood cells — which is surprising because people thought it would go up.
People who ate soybean oil daily for a month tended to have slightly lower levels of a key inflammation signal called IL-6, though the result wasn’t strong enough to be certain.
Incorporation of dietary polyunsaturated fatty acids from seed oils into cell membranes increases lipid peroxidation, triggering chronic low-grade systemic inflammation.
Eating a lot of soybean oil for a month lowered levels of DHA — a healthy omega-3 fat — in red blood cells, possibly because the two types of fats compete to get into cell membranes.
