Which substances prevent cholesterol from oxidizing in the arteries?

Antioxidants are substances that play a critical role in preventing the oxidation of cholesterol within the arteries. This is significant because the oxidation of low-density lipoprotein (LDL) cholesterol can lead to the formation of plaques in blood vessels, contributing to atherosclerosis and increasing the risk of cardiovascular diseases. Antioxidants neutralize free radicals, which are unstable molecules that can cause oxidative stress and damage to cells, including lipoproteins.

In contrast, vitamins and minerals, while essential for various body functions, do not specifically target the oxidative processes related to cholesterol. Lipids refer to a broad class of molecules including fats, oils, and cholesterol itself; they do not inherently possess the protective qualities against oxidation without the influence of antioxidant compounds. Therefore, antioxidants stand out as the essential substances that actively prevent the harmful oxidation of cholesterol in the arteries.
