But there is no which kind of blueberries are the most nutritious such a statement, only the taste of each species Not the same division, because blueberries are rich in anthocyanins,
Blueberry fruit in addition to sugar, acid and vitamin C, but also rich in vitamin E, vitamin A, vitamin B, arbutin, protein, anthocyanosides, dietary fiber, as well as rich in potassium, iron, zinc, calcium and other minerals. It has been determined that per 100 grams of blueberry fresh fruit in the anthocyanoside pigment content of up to 163 mg, protein 400 to 700 mg, 500 to 600 mg of fat, carbohydrates 12.3 to 15.3 mg, vitamin A up to 81 to 100 international units of vitamin E2.7 to 9.5 micrograms, SOD5.39 international units of a variety of vitamins are higher than other fruits. Trace elements are also high, each gram of fresh fruit contains calcium 220 to 20 micrograms, phosphorus 98 to 274 micrograms, magnesium 114 to 249 micrograms, zinc 2.1 to 4.3 micrograms, iron 7.6 to 30.0 micrograms, germanium 0.8 to 1.2 micrograms, copper 2.0 to 3.2 micrograms. Belongs to high amino acid, high zinc, high iron, high copper, high vitamin fruit, has a good nutritional health effects, including enhancing eyesight, eliminate eye fatigue, preventing cerebral aging, anticancer, soften blood vessels, enhance the human body immunity, etc., and its nutritive value is much higher than the apples, grapes, oranges and other fruits, known as "the king of the world's fruits". After many years of clinical use and scientific research, the medical profession has proved that blueberries have the following functions:
Improve vision, slow down fatigue
Anthocyanins in blueberries can promote the retinal cells in the translucent violet re-generation, which can prevent myopia, retinal detachment, and at the same time on the dry eyes, eye astringency, see the wind and tear and senile flower eye has a very obvious effect. It has therapeutic effects on pre-mature cataract, degeneration of macular tissue at the bottom of the eye, night blindness and retinopathy. Its health care mechanism is to protect the microvessels of the eye and promote blood circulation in the eye.
At the same time, blueberries have the ability to accelerate the regeneration of retinal violet park, which is indispensable for good eyesight. Legend has it that during the Second World War, the British Royal Air Force would eat blueberry food before a mission, which was said to be able to enhance the pilot's eye function and enhance the night's light perception. The U.S. Department of Education since 2000, blueberries as primary and secondary school students to protect the eyes of nutritional food, requiring each person to eat at least one cup of blueberries per week, fresh or processed; Japanese blueberries as "smart fruit", primary and secondary school students have been from the past, "a glass of milk every day! ", to "a bag of blueberries a day, smart generation brain".
Improve sleep
Anthocyanins in blueberries can penetrate cells, protect cell membranes, not oxidized by free radicals, with strong antioxidant and anti-allergic function, can cross the blood-brain barrier, can protect the brain nerve not to be oxidized, can stabilize the brain tissue function, to improve the quality of human sleep. Improve sleep.
Anthocyanins have the effect of deep cellular protection of cell membranes from free radical oxidation, with strong antioxidant and anti-allergic function, can cross the blood-brain barrier, can protect the brain nerves are not oxidized, can stabilize the function of brain tissues, and to protect the brain from harmful chemicals and toxins, so as to completely improve the quality of sleep.
Enhancement of autoimmunity
Blueberry berries can enhance the resistance of the body to infectious diseases. Blueberry berries are also a high fiber food and according to the USDA, 145g of blueberry fruit contains at least 2.9g of fiber and hence can be a good source of fiber in your daily diet. Blueberries contain a considerable amount of potassium, which helps to maintain fluid balance in the body, normal blood pressure and heart function, with only 80 calories. Blueberries have a close relationship in the fight against free radicals, especially reactive oxygen species and various diseases such as cancer, diseases of the innate immune system, cardiovascular disease.
Beauty
Blueberries contain anthocyanins, flavonoids and other components with antioxidant, improve blood circulation, promote metabolism and other functions, enhance skin elasticity, keep smooth and delicate, prevent or reduce skin diseases and wrinkles early appearance, and even eliminate scars, remove pigmentation, whitening skin.
Anti-aging, cancer prevention
Blueberries, especially the wild variety, have antioxidant function. Blueberries have a high capacity to absorb free radicals, which can reduce the damage of oxygen free radicals to cell membranes, DNA and other cellular components, preventing dysfunction in the body and the occurrence of many age-related diseases. At the 2004 International Longevity Conference, some scientists disclosed details of research showing that some specific compounds in blueberries have a strong effect on the suppression of degenerative brain functions, including Alzheimer's disease. Enhanced Memory.
Blueberries have a very high antioxidant in all fruits and vegetables can enhance brain power and reduce Alzheimer's premature dementia, etc., the scientific diet needs anthocyanins, which help to slow down the aging process, and if you choose anthocyanins, blueberries are heavy blueberries are an important choice. It is known to prevent dysfunction, improve short-term memory, and improve balance and coordination in the elderly. Blueberries contain an antioxidant, ellagic acid, which blocks the metabolic pipeline that promotes cancer production. The free radical-scavenging effect of anthocyanins prevents cancer cells from spreading smoothly, thereby protecting more cells from cancer, and blueberries are ranked as the number one anti-cancer food in the United States and Japan.
Anti-inflammatory, anti-allergy
Blueberries contain tannins, which can reduce inflammation of the digestive system; can reduce hemorrhagic E. coli and promote urinary tract health. Anthocyanins selectively bind to the connective tissues of the joints to prevent swelling, help heal damaged tissues, and relieve pain. Anthocyanins have the ability to inhibit histamine and other inflammatory compounds, making them very effective in the treatment of asthma. Blueberries have been shown to be very effective in age-related urinary frequency, prostatitis, and infections in the urinary tract.
Preventing high blood pressure
Research by British and American scientists has shown that eating anthocyanin-rich blueberries can help prevent high blood pressure and the diseases it causes, and that the risk of developing high blood pressure is 10% lower than for those who don't eat many blueberries.
Lowering cholesterol and preventing cardiovascular disease:Blueberries contain antioxidant and anti-inflammatory components such as anthocyanins, vitamin C, vitamin E, and pectin, which are effective in lowering cholesterol, preventing atherosclerosis, promoting cardiovascular health, and preventing cardiovascular disease. Tests have confirmed that blueberries are one of the world's foods with a high oxygen free radical absorption capacity. Strengthen blood vessels, improve circulation.
Proanthocyanidins can improve blood circulation, restore lost microvascular efficacy, strengthen fragile blood vessels, and thus make blood vessels more elastic. For people with venous insufficiency, proanthocyanidins are effective in reducing pain, swelling and night cramps.
