Protein powder
Just eat enough fish and egg milk every day. You really don't need to add protein powder.
Even if you go to the gym to gain muscle, unless you are a bodybuilder, the average person only needs to eat one or two lean meats and one or two eggs more than usual.
But protein powder is not without its merits. When the proportion of protein in the diet is too low, people are prone to puffiness, physical weakness, fatigue, fear of cold, weak digestion and edema. Especially for the elderly who have less muscles, poor digestion and small appetite, it is necessary to ensure the supply of protein.
However, many elderly people are afraid of cholesterol, afraid to eat fish, eggs and milk, and their diet is insufficient in protein. But when they bought protein powder, they thought it was too expensive to waste, so they ate it obediently. At this time, supplementing protein powder can really bring benefits to the body.
In the hospital, many postoperative patients can't get enough protein from food because of their poor digestion and absorption ability, so they need to be supplemented with enteral nutrition. It is very effective to use hydrolyzed protein products.
Investigations at home and abroad show that the hospitalization time of protein and various malnutrition patients is prolonged, and the recovery speed is slow or even impossible.
In short, if you have a good mouth and normal digestion, and there is no shortage of fish, eggs and milk, don't spend a lot of money on protein powder.
Grape seed capsule
Grape seed capsule mainly supplements antioxidant "proanthocyanidins", which is helpful to some people who lack antioxidant substances, but it is not as magical as the legendary "whitening effect".
Because proanthocyanidins can reduce the activities of various digestive enzymes and affect the absorption and utilization of various trace elements, women with daily indigestion, anemia and zinc deficiency and fear of cold should never make up grape seed capsules indiscriminately, nor should they think that grape seed capsules are skin whitening agents. Otherwise, not only can you not turn white, but you may have a yellower face, worse digestion and colder body.
High calcium milk
Cattle and sheep (milk) are rich in calcium, including human milk. There is no need to increase the calcium content on the basis of this high calcium content.
Some surveys have found that consumers who buy high-calcium milk mainly don't understand the basic common sense that "milk itself is rich in calcium". In fact, the calcium content of high-calcium milk is only higher than that of ordinary milk 15%~20%. Nowadays, high-calcium milk is rare in Beijing market. Why? I guess it's because it can't meet the national standard. According to the requirements of GB28050-20 1 1, if it is claimed to increase the content of a certain nutrient, it will be at least 25% higher than that of ordinary similar products. For milk, it is technically difficult to add so much calcium, which easily leads to the instability of milk sol system. Drink more ordinary milk and yogurt and eat more green vegetables and tofu every day, and naturally there will be calcium.
fish oil
Marine fish not only contains fish oil, but also contains protein, vitamins and trace elements. Studies have shown that eating non-fried marine fish 2~3 times a week is conducive to preventing cardiovascular and cerebrovascular diseases and cognitive decline in the elderly, and is also conducive to ensuring the intellectual development of fetuses and babies. As for the effect of fish oil, the research results are inconsistent. However, in some cases, fish oil is still useful. For example, people in some areas can't eat fish every day, and vegetarians don't eat fish, so it is meaningful to follow the advice of professionals to supplement fish oil properly during pregnancy or during certain diseases. (It is best to eat fish)
ferment
The "enzyme oral liquid" bought in the market and the "fruit enzyme" brewed at home are not "enzyme preparations", but "enzymes will be inactivated when they enter the intestine", which proves that the enzyme oral liquid is useless and wrong. Many papers in China show that the fermentation broth of these fruits and vegetables contains many organic acids, reducing sugars, many B vitamins, and may also contain other trace metabolites. However, most of these studies are in the primary stage, and how much health care effect they can produce and how much they drink remain to be studied. Moreover, the quality control of the fermented liquid of homemade fruits and vegetables is not good, which may produce trace toxic substances, which is more dangerous. (self-control is risky)
Nourishing stomach biscuit
It is illegal to say that stomach-nourishing biscuits are unreliable, that is, they have no health food certification, but they want to claim health care efficacy. Compared with ordinary food, it is too expensive to sell. However, it is a bit biased to say that stomach-nourishing biscuits are not as good as soda biscuits.
Soda cookies are not necessarily good for the stomach. The fat and calories of soda biscuits are not lower than other biscuits, but the blood sugar response is the highest among all kinds of biscuits. Diabetic people are not worth eating at all. Soda biscuits are not good for patients with hypochlorhydria, but may temporarily relieve discomfort for patients with hyperchlorhydria.
Simply put, don't eat two cookies, just eat three meals directly. (Try to eat fewer cookies)
First spawning
How high is the nutritional value of first-born eggs? Without data, it is difficult to evaluate whether some trace components are higher than other eggs. Eggs contain hundreds of protein, lecithin, lutein, zeaxanthin, 12 vitamins and various trace elements, not only protein. But generally speaking, even if an egg is slightly different from other eggs in some micronutrient indexes, it is difficult to play an obvious role in its daily nutritional supply. (I don't know when the fire started)
Black wolfberry
Black Lycium barbarum is indeed the highest anthocyanin content in food on the market at present, and there are data to prove it. It is unreasonable to say that it is not as good as eggplant, purple cabbage and purple potato.
If we spend the same amount of money, if we buy our daily vegetables such as purple cabbage and purple potato, we will have a lot more anthocyanins than black wolfberry. However, if you buy a box of black wolfberry, it is better to buy several bags of eggplant.
brown sugar
The difference between brown sugar and ordinary brown sugar is that it has a high degree of Maillard reaction, and its color is particularly dark after cooking for a long time. Maillard reaction produces aroma, so the flavor of brown sugar is stronger than that of ordinary brown sugar. However, the acrylamide content produced by brown sugar is high. Small intake of such products can promote appetite, while large intake may promote aging and chronic diseases (there are a few animal experiments and population surveys, but there is no conclusion). If you like the taste of brown sugar, it's ok to have a drink to comfort yourself during your period, but it's unwise to eat a lot every day for health.
Children's health food (soy sauce, etc.). )
Children's soy sauce bottles are small and more expensive than ordinary soy sauce, but the ingredients and nutrients are almost the same as ordinary soy sauce. Not that it will be harmful, but that it is not a product more suitable for children. Sodium is not low, the nutritional value is not necessarily high, and there is no relevant standard. Just buy ordinary high-quality soy sauce directly.
