Goji berries are solanaceous, wolfberry plants, well-known at home and abroad, it is medicinal and food homologous, dried wolfberries can be used in medicine, fresh wolfberries can be eaten as fruits. In terms of medicinal use, Ningxia goji berries were included in the 2010 edition of the "Chinese Pharmacopoeia", wolfberries are sweet in taste, flat in nature, returned to the liver and kidney meridians, have the effect of nourishing the liver and kidneys, improving the eyes and moisturizing the lungs, and are used to tonify the liver and kidneys, nourishing and strong, and can be applied by those who are weak in the liver and kidneys.
In terms of nutrition, goji berries have high nutritional value, rich in protein, dietary fiber, vitamin A, iron, calcium, zinc, potassium, selenium and other nutrients, as well as goji polysaccharides, betaine, carotenoids, lutein, flavonoids and other health care ingredients, goji polysaccharides have the effect of scavenging free radicals, anti-aging, anti-fatigue, anti-tumor, protection of the liver, promote immunity and so on. Flavonoids and betaine have anti-fatty liver and regulate lipid metabolism. Carotenoids and lutein have the effect of improving immune function, preventing and inhibiting tumors and atherosclerosis.
Compared with fresh goji berries, dried goji berries lose part of their water and vitamins, concentrate sugar, increase calories, but also concentrate dietary fiber, minerals and health ingredients, there are gains and losses. For medicinal purposes, the Chinese Pharmacopoeia (2010 edition) recommends that the dosage of Ningxia goji berries is 6 to 12g, and there are about 3-6 capsules of 1g goji berries, which should be used according to medical advice. As a fruit, the "Dietary Guidelines for Chinese Residents" (2016 edition) recommends that you can eat 200 to 350g of fresh fruit per day, because it is difficult to buy fresh goji berries in the market, you can replace them with other fruits, in terms of nutrition, dried goji berries can not replace fresh goji berries.
Black goji berries, also known as black fruit goji berries, and red goji berries are close relatives, all belong to the solanaceae, goji berries are plants, but the price of black goji berries is dozens of times higher than that of red goji berries, what is the superiority of black goji berries? Sun Yaoshi explained it to you today. The reason why black goji berries appear black and purple is because they contain a large number of anthocyanins, which are polyphenolic pigments that have antioxidants, scavenging free radicals, regulating intestinal flora, protecting nerve cells and protecting vision. Testing confirmed that black goji berries are indeed the highest anthocyanin content in the current commercially available food, each gram of black goji berries contains about 8-31mg of anthocyanins, but studies have confirmed that the oxygen free radical clearance rate of red goji berries is 94%, black goji berries are 95%, and black goji berries are only slightly better. In addition, anthocyanins are not unique to black goji berries, common purple potatoes, blueberries, purple cabbage, mulberries, cherries and other foods are also rich in anthocyanins, although the content is slightly lower, but from the cost performance point of view, obviously black goji berries do not dominate. In terms of nutrition, black goji berries contain protein, potassium, iron, zinc, strontium and other nutrients and health care ingredients such as goji polysaccharides, but the content of carotenoids, lutein, betaine is far less than that of red goji berries, so in terms of medicinal value and nutritional value, red goji berries are similar to black goji berries, and there is no need to spend a lot of money to buy black goji berries.
The "Guidelines for the Diagnosis and Treatment of Hyperuricemia and Gout in China" (2019) recommends that patients with hyperuricemia limit the intake of alcohol, hyperpurine and high fructose diet, encourage the intake of dairy products and fresh vegetables and drink water in moderation, and do not recommend or restrict the intake of soy products such as tofu. The high-purine diet includes animal offal, meat, broth, seafood, etc., and the high-fructose diet includes juice, cola, grapes, lychees, bananas, cantaloupe, etc., because fructose can accelerate purine synthesis, promote uric acid production, and thus induce gout.
Fresh goji berries as a fruit do not have a high sugar content, suitable for patients with hyperuricemia to eat, but after making goji berries, the sugar is concentrated, and the sugar content is significantly increased. For patients with hyperuricemia, it is advisable to choose grapefruit, strawberries, lemons, oranges, blueberries and other low fructose fruits, it is best not to eat dried fruits, if you like to eat dried goji berries, up to 10-20 capsules per day.
In modern pharmacological research, almost all of them isolate the "bioactive ingredients" in goji berries, analyze and determine their biochemical properties, and explore the function of these extracts in animal experiments. Active ingredients such as goji polysaccharides, flavonoids, betaine and so on may have hypoglycemic effects, but whether drinking goji berries soaked water or eating goji berries has hypoglycemic effects, whether it has clinical significance, what is the dosage used, and how safe it is for long-term use, etc., all need to be verified by further human clinical trials. Diabetics can drink goji berries in water, but do not delay the regular treatment.
