Women are convinced that red dates and brown sugar are good for enriching blood.
Argument basis: Red dates and brown sugar are rich in iron and red, so they help to enrich blood.
The rumor is shattered: the iron contained in red dates and brown sugar is "non-heme iron", which has low absorption rate, generally only 1%~5%, and is easily influenced by dietary fiber, oxalic acid and phytic acid in other foods, so their iron supplementation effect is often poor.
Nutritional truth: Jujube is a snack with high nutritional value, and it is high in dietary fiber and minerals, so it can be eaten often. The nutritional value of brown sugar is higher than that of white sugar, and it can replace white sugar for seasoning, but it should not exceed 25 grams per day.
Eating pig's trotters can beautify the face.
Argument basis: trotters are rich in collagen, which is good for the skin and can be used for beauty.
The rumor is shattered: after eating collagen, it needs to be digested and decomposed into amino acids or "peptides" to be absorbed into the blood, and the absorbed amino acids need to be recombined to form the protein needed by the human body, and will not directly appear on the face in the form of collagen. Therefore, eating collagen can only increase the supply of amino acids at most, and it can't be beautiful.
Nutritional truth: the nutritional value of collagen itself is not high, and the trotters are rich in fat. People with high cholesterol and cardiovascular diseases had better eat less.
Lemonade whitening
Basis: Lemonade is rich in vitamin C, which helps to whiten skin.
Rumor shattered: Lemon is not the fruit with the highest vitamin C content. When brewing, the amount of lemon is very small, and the vitamin C in it will not be completely dissolved and diluted by water, so the vitamin C content in lemon water is not high.
Nutritional truth: Lemonade has a unique taste and contains almost no energy, but it contains potassium, a small amount of vitamin C and flavonoids, so it is a good drink.
You can lose weight without eating staple food.
Argument basis: staple food is high in energy, and not eating staple food helps to lose weight.
The rumor is shattered: 1 g fat produces 9 kilocalories, and 1 g carbohydrate produces 4 kilocalories. The staple food is mainly carbohydrates, so it is unreasonable to say that the staple food is high in calories. Eating less staple food may cause fatigue, osteoporosis, skin degradation, memory loss and other problems.
Nutrition truth: Many staple foods, such as oats, red beans, buckwheat and black rice, are not only low in calories, but also provide satiety, which is conducive to weight loss.
Eating papaya helps breast enhancement.
Argument basis: the saying of papaya breast enhancement has been circulated since ancient times. Some people think that papaya enzyme and vitamin A can stimulate female hormone secretion and help breast enhancement.
The rumor is shattered: the breast enhancement of papaya recorded in ancient books originated from the theory of "complementing shape with shape" and has no scientific basis. Papain is a protease. After entering the human body, it will be decomposed by pepsin and lose its activity, which will not play a role at all. Vitamin A will not stimulate the secretion of estrogen, so papaya has no breast enhancement effect.
Nutrition Truth: Papaya is a kind of fruit with high nutritional value. Its rich beta carotene can be converted into vitamin A in human body, which helps to protect eyes. In addition, it is also rich in nutrients such as vitamin C, potassium and magnesium, which can be eaten often at ordinary times.
Eating soy products can lead to breast cancer.
Argument basis: Soybean products contain a lot of phytoestrogens, which are easy to cause problems such as breast cancer.
The rumor is shattered: the phytoestrogen in soybean is mainly soybean isoflavone, which is not equal to human estrogen. It has two-way regulation function, can make up for the deficiency of low estrogen level in the body, and can prevent and treat some diseases related to the decline of estrogen level.
Nutrition Truth: Many studies show that eating soy products can not only prevent breast cancer, but also reduce its risk. It is recommended to eat 30 to 50 grams of soybeans every day.

Myth 2: Eating sweet potatoes is easy to be obese?
Correction: the starch content in "potato" is still relatively small. Starch does not turn into fat immediately after being ingested, but provides a basic energy source for daily activities of the body. Therefore, as long as potatoes are cooked properly and do not add too much oil, potato food is still a healthy food.
Common daily eating habits
1, the more soy products you eat, the better?
Protein in soybean will hinder the human body's absorption of iron, and excessive intake of soybean protein will inhibit 90% of normal iron absorption, resulting in iron deficiency anemia, which is manifested in different degrees of fatigue, drowsiness and other anemia.
2. Is honey low in calories?

When the oil temperature is above 200 degrees, not only the unsaturated fatty acids beneficial to human body in vegetable oil will be oxidized, but also a gas called "acrolein" will be produced. It is extremely harmful to the human respiratory system. In addition, "acrolein" can also make oil produce peroxides with strong carcinogenicity. Therefore, it is best to use 80% hot oil for cooking.

9. Fresh vegetables are healthier than frozen vegetables?
If it refers to fresh vegetables just picked from vegetable fields, there is no problem with this statement. But in fact, most of the vegetables we eat are not so fresh. They are usually stored for a few days, and vitamins will gradually lose during storage. On the contrary, vegetables frozen at ultra-low temperature can retain more vitamins, because vegetables are frozen quickly after picking, preventing the loss of vitamins.
10, is it healthier to eat vegetables raw?
Many vegetables are really healthier when eaten raw, because they can best retain the nutrients in them. But raw food is not suitable for all vegetables. For example, carrots are rich in vitamin A, but only by eating carrots and consuming fat can people get enough vitamin A from them.
