Today, health is prevalent, fish oil, protein powder, propolis, shark fin, bird''s nest. There are a variety of expensive health products, but do these really have magical effects?

　　Fish oil

　　Fish oil is better than eating fish directly

　　Fish oil for heart The benefits of vascular health have been widely recognized, and its impact on fetal development has also been initially confirmed in recent years. However, since fish oil comes from fish, purifying fish oil is not stable.

　　 In terms of health, eating fish is better than eating fish oil. In addition to fish oil, fish also provides high-quality protein and trace elements such as vitamins and minerals. The saturated fatty acids in fish meat are very low, which is very beneficial for cardiovascular health.

　　Protein powder

　　Protein powder Do you really need to replenish protein powder?

　　A jar of 400g protein powder is sold to Two or three hundred pieces, in fact, it is just a powder of purified soy protein, casein, whey protein or a combination of the above-mentioned protein combinations.

　　The protein required for healthy adults is 50-70 grams per day, which is about 10 grams per kilogram of body weight. These amounts of protein can be completely satisfied by normal diet.

　　Healthy people with a normal diet do not need to supplement protein powder.

　　Sea cucumber---the quality of protein is not as good as egg

　　The value of sea cucumber lies in protein, protein has high quality and low quality, its quality is mainly passed by people Judging the absorption rate of amino acids in protein depends on whether the amino acids conform to the human amino acid pattern.

Although the protein content of sea cucumber is very high, the quality is not high.

　　 and eggs are the most suitable for human body amino acid pattern, eating sea cucumber is better than eating two eggs a day, and then mix with some soy products and green vegetables, the protein intake of the latter is far in quality and quantity Far better than sea cucumber, and cheap.

　　Shark fins—an intoxicating price/performance ratio

　　The main nutritional component of shark fin is collagen eggs, but its nutritional value is different from trotters, chicken skin, fish skin, etc. Not much. Scientific research has found that although the collagen content in shark fin is very high, there are still some differences in the proportion of amino acid composition compared with human protein. The essential amino acids it contains only account for 20.5% of the total amino acids, and collagen lacks tryptophan Acid, cannot be converted into collagen.

　　In short, the nutritional value of shark fin does not have any obvious advantages compared to trotters, but the price is very expensive.

　　Propolis--the efficacy has not been authoritatively certified

　　Propolis is a kind of resin obtained by bees from plant spores plus their own secretions Glue, used to build hives, can block bacteria and other external invasion.

　　The ancients in Greece, Rome, Egypt and other places used it to heal wounds, reduce inflammation, and make mummies.

　　Many businessmen are aiming at this, boasting that propolis can be used for "antibacterial", "antiviral", even "modulating immunity", "antitumor",

　　 In fact, propolis Most studies on efficacy have focused on animals or cells, and no clear conclusion has been drawn on the efficacy of humans in medicine.

　　Enzymes --- not "weights" for weight loss

　　 The standard term for "enzymes" is "enzymes", which are needed for various biochemical reactions in the human body Enzyme participation, such as fat burning requires lipase, which is the theoretical basis of "enzyme weight loss".

　　 But the enzyme must first pass through the stomach, and the acidity in the stomach is very strong. Generally speaking, the enzyme is difficult to withstand the test in such an environment. There are also gastric protein enzymes in the stomach that are produced specifically for the acidic environment, and proteases from the small intestine are more aggressive.

　　 Lost the "clearing enzyme" of the complete structure, naturally no longer active, let alone lose weight. Weight loss or diet adjustment and exercise is the only way.

　　Final suggestion: Everyone must understand clearly when purchasing supplements.
