Nothing is better, only one is more suitable for you! In terms of fatty acid composition, the proportion of total unsaturated fatty acids is that corn oil is larger than sunflower oil, but sunflower oil contains more polyunsaturated fatty acids. However, most of the essential fatty acids exist in polyunsaturated fatty acids, so the content of essential fatty acids in corn oil is less. However, there are too many polyunsaturated fatty acids, which are easy to oxidize and difficult to preserve, so the storage of sunflower oil is not as good as that of corn oil. Compared with the nutrient composition, the contents of vitamins A, B, D, E and trace elements in sunflower oil will be slightly higher, but the phytosterol content in corn oil will be higher, so each has its own advantages. To sum up, personal suggestions: the prices of the two oils should be in the middle level, which is good for the health, but sunflower seed oil is more suitable for young people and people who do manual labor. Moreover, when buying sunflower seed oil, we should fully see its preservation methods, whether to add artificial antioxidants or not, and it is better to buy small packages! The taste of corn oil should be more clear, and it is more suitable for middle-aged and elderly people. However, at present, there is no distinction between good and bad corn oil on the market, and the price is too high. You need to fully understand and distinguish it when buying it.
