Vitamin E is a vitamin dissolved in oil. It is an antioxidant that can scavenge oxygen free radicals, thereby protecting lipids on the cell membrane, and the oxidation of lipids is closely related to coronary heart disease, cancer, aging, etc. Vitamin E is an indispensable nutrient for the human body. But "need" does not mean that the bigger the better. Vitamin E deficiency rarely occurs in the population, and only a few people may have problems: people with bile deficiency or people with difficulty in fat metabolism; Rare genetic abnormalities lead to lack of vitamin E transfer protein; infants who are severely underweight due to premature birth. These conditions are not easy to occur in the population. What is the point of this passage? ['Normal people do not need to add vitamin E.', 'The role of vitamin E should be properly understood.', 'There is a misunderstanding of vitamin E.', 'Pay special attention to people who may lack vitamin E.']
