At present, many friends have paid attention to this black mineral water. The packaging of "Black Water" is simple and cool, and the big "blk" is printed on the transparent plastic bottle. . Compared with ordinary mineral water, the price of 70 yuan /500ml is sky-high. At present, it is not sold in traditional channels such as supermarkets, and can only be purchased through e-commerce channels such as Taobao. According to the publicity materials of black mineral water, "Black Water" is a Canadian mountain spring with fulvic acid added. Fulvic acid is a nutritious natural compound, rich in more than 60 minerals and trace elements such as calcium, iron, zinc, iodine and selenium. It has been used in alternative therapy for centuries. "Fulvic acid" will turn black when it meets water, which adds a special feeling to this drink.
But for the propaganda of "black water", some nutrition experts said that "fulvic acid" is a kind of humic acid, which can promote the growth of plants. There are a lot of research documents about the role of plants, but little about the role of animals. As a kind of food, the beneficial effects of fulvic acid on the body cannot be exaggerated. From the point of view of nutrition, only more than 20 elements are found to constitute human tissues, which are necessary for metabolism and maintaining physiological functions, such as calcium, potassium, phosphorus, copper, iron, selenium and iodine. The human body does not need more than 60 kinds of elements, even if it enters the human body, it may not be absorbed. Consumers are reminded not to blindly pursue novelty and be overly superstitious about foreign products when purchasing.
