The efficacy and function of blueberries, we often eat a variety of foods in our lives. Fruit is rich in vitamins, and eating fruit also contributes to the digestion of human intestines. Let's take a look at my collected articles about the efficacy and function of blueberries. Welcome to read them.
Efficacy and action point of blueberry 1
1, eye protection
Mainly refers to the substance "anthocyanin" contained in blueberries. It can help the regeneration of retinal cells and relieve the symptoms of moderate and severe myopia. In addition, it can also prevent retinal detachment, so it has the effect of improving vision. Staring at computers, mobile phones and other electronic products for a long time can also effectively relieve eye fatigue.
2. Suppress infectious diseases
Blueberry berries are resistant to some infectious diseases. In addition, it can effectively resist free radicals and has an effect on some immune system diseases.
Step 3 supplement nutrition
It has a high fiber content and is a good fiber source in daily life. It also contains a lot of potassium, which can maintain the balance of liquid in human body and the stability of blood pressure. In addition, although it is nutritious, it does not contain high calories and can be safely eaten.
Step 4 prevent aging
It contains many substances, which make it very antioxidant and can delay aging. Especially for some rapidly aging parts and tissues, it is very effective.
5, enhance memory
Can inhibit Alzheimer's disease. It can also improve short-term memory and improve human coordination.
Efficacy and action point 2 of blueberry lowers blood sugar.
People with diabetes can eat more blueberries, which is good for lowering blood sugar. Everyone can eat blueberries for five minutes every week, and sticking to them for two months can obviously improve the ability of blood sugar regulation.
Enhance immunity
Most diseases of the body are related to oxygen free radicals. Studies have shown that proanthocyanidins contained in blueberries can enhance human immune system and improve human immunity, which has a direct or indirect preventive effect on this disease.
Cancer prevention
Procyanidins in blueberries can also ensure the actual effect of preventing tumors. Eating a cup every day can prevent cancer.
Strong bones
Blueberries contain nutrient element manganese, which plays a leading role in bone growth. It is found that the relative density of bone hyperplasia in children who like to eat blueberries is higher than that in children who don't eat blueberries.
Fitness and lose weight
Blueberries are low in calories and not easy to gain weight. Moreover, polyphenols contained in blueberries can degrade abdominal fat, which is beneficial to slimming.
Avoid cystitis
Some ingredients in blueberries can prevent bacteria from adhering to exposed walls and avoid cystitis and urinary tract infection. It is found that eating 1 handful of blueberries every day is beneficial to improve the situation of urinary tract infection.
Improve sleep quality
Procyanidins in blueberry can pass through the blood-brain barrier to prevent the central nervous system from being oxidized, which can make the brain function more stable, increase the oxygen content of the body and improve the quality of sleep.
Enhance the charm of the human brain
Studies have shown that eating more blueberries can slow down brain decline and enhance memory. This is because the strong flavonoids in blueberries can eliminate the harmful substances accumulated in the human brain, and then maintain the human brain. When going to Japan, blueberries are called "fruits of wisdom".
Efficacy and Action Point of Blueberry No.3 I. Conventional Nutritional Components
Blueberry has delicate pulp, unique flavor, moderate sweet and sour taste and pleasant aroma. Blueberries are rich in conventional nutrients such as protein and vitamins, and the contents of minerals and trace elements are also considerable. So blueberry is called "fruit queen", which really deserves its name!
Second, special nutrients
1, anthocyanin
Anthocyanin is a very important plant water-soluble pigment, which belongs to pure natural anti-aging nutritional supplement and is the most effective antioxidant bioactive agent discovered by human beings at present. The content of anthocyanins in blueberry is very high, and the types of anthocyanins are also very rich. It was found that the anthocyanin content in the fruit of Vaccinium uliginosum was as high as 15. Although the anthocyanin content of different varieties of blueberry is not the same, it is generally high.
2. Total acids and organic acids
The content of organic acids in blueberry accounts for more than half of the total acid content. Most organic acids are citric acid, others are ursolic acid, quinic acid and malic acid. Ursolic acid, also known as ursolic acid, belongs to a class of weakly acidic pentacyclic triterpenoids. It is a functional component of many natural products and has a wide range of biological activities, especially in anti-tumor.
3. Phenolic acid
Blueberries contain many kinds of polyphenols, among which phenolic acid is an important one. Phenolic acid is a phenolic substance with good nutritional function and antioxidant activity. Blueberries contain more than ten kinds of phenolic acids, among which chlorogenic acid, also known as caffeic tannic acid, is the highest. It is found that it has obvious inhibitory effect on many cancers (lung cancer, esophageal cancer, etc.). ), and its antioxidant effect is also very strong.
4, superoxide dismutase
Superoxide dismutase (SOD) is an acidic metalloenzyme widely existing in organisms, and it is an important free radical scavenger in organisms. Its main function is to specifically scavenge superoxide anion free radicals produced in biological oxidation, and it is known as "2 1 century health care gold". Blueberries are rich in superoxide dismutase. Although the SOD content of different varieties of blueberry is slightly different, there is little difference in general.
5. gum
Pectin is a polysaccharide polymer. Scientific research has found that pectin can effectively remove the undigested chyme and other toxic substances in the human body, and at the same time help to regulate the balance of postprandial blood sugar and intestinal flora, and it also has a good preventive and adjuvant treatment effect on many modern "civilized diseases". The pectin content in blueberry is rich, which is about 1-3 times that of ordinary apple or banana.
6, rosewood stilbene
Chelidonium majus, named after its first discovery in Chelidonium. In 2004, scientists first isolated pterostilbene from berries such as blueberries and grapes. It is found that pterostilbene also has good antioxidant, anticancer, anti-inflammatory and antidiabetic effects. The role of pterostilbene in anti-cancer has also been highly concerned by people, especially in anti-colon cancer, pterostilbene has shown very gratifying results.
