Does eating more blueberries have the effect of protecting the eyes?

Blueberries are good for your eyes because they contain a lot of anthocyanins, antioxidants. Traditionally, blueberries have been rumored to have several functions. Improving night vision with blueberries can be traced back to World War II, when RAF pilots took blueberries before night raids, supposedly to help them see the enemy in particularly dimly lit places.

<> later research suggested, however, that it may not have helped. The National Institutes of Health says blueberries"May have no effect on improving night vision"。But in fact, a 2004 review in the Journal of Ophthalmology found little scientific basis for the theory that blueberries can improve night vision in people with healthy eyes.

And for people with eye diseases, an analysis of 30 clinical trials found that blueberries were effective in improving night vision"It has not been rigorously researched at all"。

According to a 2015 study published in the journal Nutrition, Health & Aging, cranberries and blueberries may help reduce eye strain associated with display end-use (i.e., computers, phones, etc.). In the study, scientists sampled hundreds of people aged 20-40 who used the display terminal and divided them into two groups: one group that took blueberry extract daily and the other who took a placebo containing powdered sugar.

After eight weeks**, through a series of questionnaires, the blueberry extract group did better than the placebo group in improving visual fatigue (e.g., eye pain, heaviness, discomfort, and foreign body sensation). In this sense, the significance of taking blueberry myopia may be to alleviate some visual fatigue, especially when looking at mobile phones and computers, but not radically.

Eating blueberries regularly is good for the eyes, because blueberries are rich in anthocyanins, and blueberries contain the highest anthocyanin content in food, vegetables and fruits. Anthocyanins have a nutritional effect on the retina of the fundus, such as rhodopsin, optic cells of the retina, etc., and belong to the essential nutrients of retinal photoreceptors.

In addition to the benefits of the retina, eating blueberries regularly also has a certain nutritional effect on the lens, because the anthocyanins in blueberries have a strong antioxidant effect, neutralizing and resisting free radicals. Because blueberries are rich in anthocyanins, they have a nutritional effect on the retina of the fundus and also have a nutritional improvement effect on the lens, so eating blueberries regularly is good for the eyes.

Blueberries are good for the eyes, blueberries have anthocyanins, and the role of anthocyanins is to help the retina in the production of a pigment called rhodopsin.

Rhodopsin helps nerve function and is gradually broken down during eye use, and is generally resynthesized immediately after decomposition. However, if you use your eyes too much, you will not be able to resynthesize, and as a result, your eyes will become less functional.

By taking in anthocyanins, which are beneficial to rhodopsin synthesis, it is expected to be effective in relieving eye fatigue and improving eye function.

It can also alleviate night blindness during the physical and mental fatigue period caused by eye fatigue, improve night vision impairment and maintain eye function.

Anthocyanins have the effect of inhibiting active nutrients and making the blood clean, which is very effective for patients with blood disorders. In addition to strengthening rhodopsin, anthocyanins can also maintain the normal structure of the eye knot tissue, strengthen the microvascular wall of the eye, promote microvascular blood circulation, maintain normal eye pressure, and alleviate a variety of eye diseases.

It has the effect of protecting the eyes, eating more blueberries will brighten the eyes, and it can also reduce the damage caused by radiation and protect the eyes.

Blueberry, a purple-black fruit, has not been in the field of vision of the Chinese people for a long time, but because of its strong medicinal value and nutritional and health effects, although it is difficult to preserve and expensive, it is still loved by many people.

As one of the five major human health foods listed by the Food and Agriculture Organization of the United Nations, blueberries are very nutritious, in addition to the sugar, acid and vitamin C of ordinary fruits, they are also rich in vitamin E, vitamin A, B vitamins, superoxide dismutase (SOD), arbutin, protein, anthocyanins, edible fiber and rich in potassium, iron, zinc, calcium and other mineral elements.

Vitamins and many minerals are familiar to everyone, let's not talk about it for the time being, just talk about some special nutrients in blueberries. Blueberries are rich in organic acids, such as citric acid, arbutin, quinic acid and malic acid, among which arbutin has a very prominent anti-tumor effect; Phenolic acids, a phenolic substance, have a very strong antioxidant effect; Superoxide dismutase (SOD) is a very important free radical scavenger that is of great significance for anti-aging; The pterostilbene in blueberries has good antioxidant, anti-cancer, anti-inflammatory, and sugar control effects.

We won't talk much about how rich other nutrients are here, but only talk about its excellent effect on vision, which is mainly due to the cryptoanthocyanins. The reason why blueberries show a purple and black color is because the anthocyanin content is extremely high, and the variety is very rich, and there are more than ten kinds of anthocyanins in blueberry fruits.

Anthocyanin is a very important plant water-soluble pigment, don't think it is a pigment, in fact, it is a pure natural anti-aging substance, and it is the most effective antioxidant bovine active agent found by human beings so far, now you know how important anthocyanins are, right?
