Soybean oil has a relatively high smoke point, which makes it a good option for high-heat cooking. It mostly consists of polyunsaturated fats, which are linked to lower cholesterol levels and a reduced risk of heart disease.
Soybean oil is rich in vitamin K, which may help maintain bone strength and reduce the risk of fractures. One animal study also found that the oil may help prevent bone loss. It contains omega-3 fatty acids, which play a key role in promoting health and preventing chronic disease.
Soybean oil is rich in vitamin E, a nutrient that can help promote skin health. Applying it topically may protect against inflammation and help the skin retain moisture. It can also be applied to the hair and skin or combined with essential oils.
