As people pay more and more attention to nutritional intake and health, more and more nutritional products appear on the market. However, these supplements really have the nutritional value of health benefits? In fact, there are 8 kinds of nutritional value of nutritional products is not as good as ordinary food, let’s take a look at which is it. Shark’s fin – nutritional value is like pig’s hooves The main nutrient of shark’s fin is collagen, but its nutritional value is similar to that of pig’s hooves, chicken skin and fish skin. Scientific research has found that although the collagen content in shark’s fin is very high, its amino acid composition ratio is still different from that of human proteins, and the essential amino acids it contains only account for 20.5% of the total amino acids. And collagen lacks tryptophan, which cannot be converted into complete protein. In short, the nutritional value of shark’s fin does not have any obvious advantage over pig’s trotters, but the price is very expensive. Bird’s Nest – Nutrition is not as high as tofu The main nutrient in bird’s nest is protein, which has one essential amino acid (lysine) and three conditionally essential amino acids. Scientific tests have found that the ingredients contained in soy products are close to the nutrients contained in bird’s nest. However, soy products also contain ingredients not found in bird’s nest, such as phytoestrogens and soy isoflavones. These hormones can also effectively prevent cardiovascular diseases and some malignant tumors. Collagen-using it for beauty is not reliable The basic theory in nutrition tells us that it is not what you eat that you can supplement. Ingested collagen can not be directly transported to the human skin, so eating collagen can not help the body synthesize collagen. Some people’s skin condition is significantly improved after eating collagen beauty products. The reason for this is that collagen products have added substances such as soy isoflavones or soybean extract. Soy isoflavones are a kind of phytoestrogens, which can significantly improve the water retention and elasticity of women’s skin, which is particularly rich in soybeans. Sea cucumber – protein quality is not as good as egg The value of sea cucumber lies in protein, which has high and low quality, and its quality is mainly judged by the absorption rate of amino acids in protein, which depends on whether the amino acids are in line with the amino acid pattern of human body. Although the protein content of sea cucumber is very high, the quality is not high. Comparatively speaking, egg is the food that best conforms to the amino acid pattern of human body. Eating sea cucumber is better than eating an egg a day, with some soy products and green vegetables, the latter intake of protein in quality and quantity are far better than sea cucumber, and inexpensive. Fish oil – better to eat fish directly The benefits of fish oil on cardiovascular health have been widely recognized. However, fish oil comes from fish and the process of purifying it is not stable. From a health perspective, it is better to eat fish than fish oil. In addition to fish oil, fish also provides high quality protein, vitamins and trace elements, and the saturated fatty acids in fish are very low, which is very beneficial to cardiovascular health. Protein powder – do you really need to supplement protein A can of 400g of protein powder sold to two or three hundred dollars, in fact, it is only purified soy protein, casein, whey protein powder or a combination of several of the above proteins constitute the powder. The protein required by healthy adults is 50~70g per day, which is about 10g per kilogram of body weight, and this amount of protein can be satisfied through normal diet. Therefore, people who eat a normal diet and are in good health do not really need to take additional protein supplements. Bee Propolis – Efficacy has not yet been authorized Propolis is a gelatinous substance obtained from the resin collected by bees from plant buds plus their own secretions, which is used to build hives and block bacteria and other foreign invasions. Ancient people in Greece, Rome, and Egypt used propolis to heal wounds, reduce inflammation, and to make mummies. Many traders have responded to this by boasting that propolis can be used as an antibacterial, antiviral, and even immune modulator and anti-tumor. However, in fact, most of the research on the effects of propolis has focused on animals or cells, and no clear conclusions have been drawn on its effects on humans. Eco Enzyme is not a miracle product for weight loss. Eco Enzyme is an enzyme, which is the theoretical basis for weight loss in human body. However, Eco Enzyme has to pass through the stomach first, which is very acidic. Generally speaking, enzymes are difficult to withstand in such an environment, leading to enzyme inactivation. There is also pepsin in the stomach, which is made for acidic environments, and protease in the small intestine is even more aggressive. Lost the integrity of the structure of the “fat enzyme” activity is naturally greatly reduced, more likely to have too obvious weight loss effect.
