Research: Finally, cooking oil has been cleared!

Large-scale studies have found that high levels of fats found in cooking oils such as soybean oil and corn oil help reduce inflammation, improve heart and metabolic health, and reduce insulin resistance.

The study was presented at Nutrition 2025, the annual meeting of the American Society for Nutrition, in Orlando, Florida. Researchers used blood markers to observe that people with more linoleic acid in their plasma had lower blood sugar, insulin resistance, and inflammation. These findings suggest that cooking oil may actually have a protective effect on health, according to the medical news site Scitech Daily.

Omega-6 and the risk of heart disease and diabetes

This new study has demonstrated that fats in cooking oils can protect against heart disease and diabetes. Scientists measured the blood levels of linoleic acid, an omega-6 fatty acid found in cooking oils, in participants and found that higher levels of linoleic acid were associated with reduced inflammation and cardiovascular and metabolic risk factors.

Linoleic acid is the most common omega-6 fat in the diet, found in many plant foods, especially in vegetable oils such as soybean and corn oil.

Scientists at the Indiana University-Bloomington School of Public Health (USA) analyzed data from 1,894 participants. The results found that higher concentrations of linoleic acid in plasma - after being absorbed through the diet - were associated with a lower risk of cardiovascular disease and type 2 diabetes.

Resolving the controversy surrounding cooking oil

“Cooking oils have received increasing attention, with some suggesting that they promote inflammation and increase cardiometabolic risk,” explained lead study author Kevin C. Maki, PhD, professor of public health at Indiana University-Bloomington. “Our study demonstrated that higher plasma linoleic acid was associated with lower levels of biomarkers of cardiometabolic risk, including those related to inflammation,” according to Scitech Daily.

Research has found that higher plasma concentrations of linoleic acid are associated with a lower risk of cardiovascular disease and type 2 diabetes.

Results are consistent with previous studies

The new study results are consistent with findings from studies showing that higher linoleic acid intake is associated with a lower risk of diabetes and cardiovascular events, such as heart attacks and strokes.

The study also found that people with higher levels of linoleic acid had lower glucose and insulin levels and insulin resistance.

The results were consistent when measuring different biomarkers, said Professor Maki. People with higher levels of linoleic acid in their blood had a lower risk of heart disease and diabetes.
