The most common food rich in vitamin A is animal viscera, but it has high cholesterol and is not suitable for large consumption.

It is recommended to eat foods with more β - carotene, such as green and yellow vegetables such as carrots and spinach, yellow fruits, eggs, dairy products, etc., because on average, 1 / 6 of β - carotene will be converted into vitamin A in the body. However, vitamin A and β - carotene are fat soluble, and it is better to eat them together with fat, so it's better to take them in or after meals.

2. Carotenoids

In addition to β - carotene, other members of the carotenoid family, such as lutein and zeaxanthin, also contribute to eye health. Sources of carotenoids include dark yellow, dark green and red fruits and vegetables, such as pumpkin, green pepper, tomato, corn, papaya, Hami melon, mango, watermelon, etc. Lutein and zeaxanthin can be found in dark green leafy vegetables, such as spinach, kale, mustard, celery, etc.

4. Vitamin C

Guava, kiwi, papaya, orange, orange, grapefruit, strawberry, etc. contain more vitamin C. At the same time, the vitamin C of fruits in this season is higher. Some vegetables not only have vitamin C, but also can provide β - carotene, such as green pepper, mustard, broccoli, spinach, tomato and so on. But vitamin C is afraid of heat, light and iron pot. It's better to eat it raw to reduce the loss of nutrients.

Vitamin E is also an antioxidant. Vegetable oil (such as olive oil, soybean oil, peanut oil, sunflower seed oil, etc.), nuts (such as walnuts, almonds, cashew nuts, peanuts, pine nuts, sunflower seeds, etc.) and wheat germ are all good sources of vitamin E. However, to control the oil intake, take the porcelain spoon for dinner as the unit, at most two spoons a day. The energy of nuts is not low, and they can only eat two a day at most. Try not to stir fry nuts with salt or sugar.
