Eating 40 ~ 80g blueberry products or 10 fresh blueberry fruit every day can improve eyesight and protect eyes. A few days ago, health experts said so in the experience activity held at Bluetune Manor, the first blueberry demonstration garden in Beijing. It is reported that people who eat 40~80 grams of fresh blueberry a day will obviously broaden their horizons and shorten the time to adapt to the dark environment. During World War II, pilots of the British Air Force ate blueberry sauce every day, which greatly improved their eyesight and bombing accuracy. They all say, "you can see things clearly in the twilight." Since the discovery of the function of blueberry, the U.S. military has supplied super dried fruit to special forces as a special food to improve vision and enhance night fighting ability. In the retina of the human eye, there is a purple pigment called rhodopsin, whose function is to transmit light stimulation to the brain, making people feel that they have seen something. When human eyes are working, rhodopsin will be decomposed by light bit by bit, and the decomposition speed will be accelerated with age. The important function of anthocyanin pigment in blueberry is to promote the biosynthesis of retinol, thus enhancing people's vision. Dr Ronald Prior of the Nutrition Research Center of the US Department of Agriculture believes that blueberries will effectively treat eye diseases, and they are studying the use of blueberries to treat a retinal disease, which will cause blindness in people over 65 years old. In modern society, eye fatigue and related eye diseases are increasing. According to the advice of American nutritionists, eating 40~80 grams of blueberry products every day can achieve the purpose of eye health care. It is precisely for this reason that since 2000, the US Department of Education has listed blueberries as a nutritious food for primary and secondary school students to protect their eyes, and requires everyone to eat at least one cup of blueberry fresh fruit or processed products every week.
