1, α -linolenic acid
Here, we should especially point out the significance of α -linolenic acid on fetal eye development. If pregnant women or newborns are short of α -linolenic acid, the DHA content in retinal phospholipids of newborns will be reduced by half, and the gray matter of the brain will be reduced by 1/4, which will obviously weaken the vision of newborns and affect their future vision.
The World Health Organization recommends that pregnant women should supplement 1000 mg of α -linolenic acid in addition to their normal diet every day. Therefore, it is recommended that mothers supplement high-purity α -linolenic acid supplements during pregnancy. There is a small amount of α -linolenic acid in food, such as nuts, walnuts, salmon, tuna and so on, but the purity of α -linolenic acid in these foods is not enough and the price is very expensive. Now there are α -linolenic acid capsules similar to cod liver oil on the market.
2. foods containing vitamin a.
Various animal livers, cod liver oil, milk and eggs, and plant foods, such as carrots, amaranth, spinach, leeks, green peppers, red sweet potatoes, oranges, apricots, persimmons, etc. When vitamin A is deficient, the adaptability of eyes to dark environment decreases, and it is easy to suffer from night blindness in severe cases.
3. foods containing vitamin C.
All kinds of fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, Chinese cabbage, fresh dates, raw pears, oranges, etc., have the highest content. Vitamin c is one of the components of the lens of the eye. If you lack vitamin C, you are prone to cataract and lens opacity.
4. Lycium barbarum is a good food for clearing liver and improving eyesight.
Especially recommended for expectant mothers is medlar, which has the effect of clearing liver and improving eyesight and is good for eyes. Lycium barbarum is rich in carotene, vitamin A, B 1, B2, C, calcium and iron, which is eye nutrition.
5. Oily fish
Pregnant women should eat more oily fish such as sardines and mackerel. This is because oily fish are rich in DHA, which is an element that constitutes the nerve membrane and can help the healthy development of fetal vision.
6, pay attention to calcium supplementation, the fetus is not easy to be nearsighted.
Calcium is not only very important for the health of pregnant women, but also an important element to protect the healthy development of the fetus. Studies have found that babies born to pregnant women with calcium deficiency are three times more likely to suffer from myopia in adolescence than those born to pregnant women without calcium deficiency. Therefore, it is very necessary to supplement enough calcium during pregnancy. Black foods such as kelp, laver, Nostoc flagelliforme, auricularia auricula and black sesame are rich in calcium, and the calcium content is more than 300mg per 100g. Milk and bean products are also ideal choices for calcium supplementation. 500ml of milk contains about 500mg of calcium.
