Research: Finally, cooking oil has been vindicated!

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 cardiovascular health and metabolism, and decrease insulin resistance.

The study was recently presented at Nutrition 2025, the annual meeting of the American Nutrition Association, held in Orlando, Florida. Researchers used blood markers and observed that individuals with higher levels of linoleic acid in their plasma had lower blood sugar, insulin resistance, and inflammation. These findings suggest that cooking oils do indeed 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 shown that fats in cooking oil may protect against heart disease and diabetes. Scientists measured the levels of linoleic acid, an omega-6 fatty acid abundant in cooking oil, in the blood of participants and found that higher linoleic acid levels helped reduce inflammation and cardiovascular and metabolic risk factors.

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

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

Resolving the controversy surrounding cooking oil.

Lead author, Professor Kevin C. Maki, PhD, of the School of Public Health, Indiana University-Bloomington (USA), explains: Cooking oils are receiving increasing attention, with some people suggesting they promote inflammation and increase the risk of metabolic cardiovascular disease. Our study demonstrated that higher plasma linoleic acid levels were associated with lower levels of biomarkers for metabolic cardiovascular risk, including those related to inflammation, according to Scitech Daily.

The study results showed that higher plasma linoleic acid levels led to a lower risk of cardiovascular disease and type 2 diabetes.

The results are consistent with previous studies.

The new study's findings are consistent with results from studies showing that higher levels of linoleic acid are associated with a lower risk of diabetes and cardiovascular events, such as heart attack and stroke.

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

Professor Maki stated: "The results are consistent when measuring different biological indicators. People with higher levels of linoleic acid in their blood have a lower risk of heart disease and diabetes."
