Vegetable oils are healthy, but too much can lead to increased inflammation

　　In order to reduce the intake of saturated fats, many people have started to consume vegetable oils, like canola oil, soybean oil, sunflower oil, corn oil, etc. They contain fats that are polyunsaturated fatty acids, which are beneficial to the body. However, the latest research has found that the intake of vegetable oils should also be controlled, otherwise it will bring adverse effects to the body.

　　The study was published in the journal Advances in Nutrition. The researchers found that when vegetable oils are heated to higher temperatures, such as when frying foods, oxidation occurs within the ω-6 fatty acids of vegetable oils, a chemical process that is harmful to humans.

　　The reason why it is harmful to the body lies in the fact that heating higher vegetable oils can contribute to increased inflammation in the body, especially when consumed in higher amounts. Researchers speculate that this may play an important role in developing Alzheimer's disease.

　　Previous studies have confirmed that the oxidation of ω-6 fatty acids not only causes inflammation, but also increases the risk of obesity, cardiovascular disease, rheumatoid arthritis and other diseases.

　　Given this, does it mean that runners can completely ban the intake of ω-6 fatty acids? Actually not, ω-6 fatty acids are vital for brain function, bone health, metabolism, etc. It comes down to the ratio of ω-6 to ω-3, and it is healthier to keep the ratio of the two at 4:1.

　　Many people consume too much ω-6 fatty acids, so it is not good for the body. This requires runners to consume more ω-3 fatty acids in general, which is good for fighting inflammation and improving heart health.
