There are rumors that:

Old corn is called "golden crop" internationally. Primitive Americans and Indians did not have high blood pressure and arteriosclerosis, which was the result of eating old corn. Old corn contains a lot of lecithin, linoleic acid, grain alcohol and vitamin E. Now many people eat lecithin in the hope that it will not harden the arteries. In fact, old corn contains the most lecithin and is cheap.

Expert opinion:

Corn is crude fiber, and both old corn and young corn are good grains. Corn is cheaper than rice, and it is easy to grow. It is necessary to advocate eating corn, especially under the background that urban people's food is too delicate.

2, pumpkin, bitter gourd to prevent diabetes?

There are rumors that:

Pumpkin can make vitamin cells and produce insulin. People who often eat pumpkins are not easy to get diabetes. Although bitter gourd is bitter, it secretes insulin substances, and people who often eat bitter gourd are not easy to get diabetes. So pumpkin and bitter gourd must be eaten often.

Expert opinion:

The causes of diabetes include genetic susceptibility and long-term lifestyle, which is a comprehensive metabolism, and it is impossible to affect its onset because of one or two foods.

Phytochemicals such as flavonoids contained in bitter gourd can regulate blood lipid to a certain extent, but can't lower blood sugar. Pumpkin is good for the prevention and treatment of diabetes, because the soluble fiber in it is good for controlling blood sugar, but pumpkin itself has high carbohydrate content. If you want to eat, you should reduce the intake of rice accordingly.

3. Is red wine anti-aging?

There are rumors that:

Red wine can lower blood pressure and blood lipid. Red grape skin contains "reverse alcohol", which can resist aging and oxidation. Drinking it often can prevent heart disease and cardiac arrest. So red wine sells well abroad. White grapes didn't reverse alcohol, so you drank it for nothing.

Expert opinion:

It is correct that grape seeds and skins have antioxidant and anti-aging effects. Drinking alcohol in moderation is also good for your health. Homebrewed wine is better than blended wine, and you can drink a little, but on the one hand, you can't drink too much, on the other hand, it varies from person to person. Red wine has a certain effect on softening blood vessels, lowering blood fat and blood pressure, but it is not as good as yellow wine in promoting blood circulation and warming stomach.

4, buckwheat "three drops", potatoes "three sucks"?

There are rumors that:

Modern people are "three highs", and buckwheat has the function of "three lows", lowering blood pressure, blood lipid and blood sugar. People who eat buckwheat are not allowed to have gastrointestinal cancer. In addition, sweet potato, sweet potato, yam, potato and so on. There is "three absorption": absorbing water, fat and sugar, and absorbing toxins.

Expert opinion:

Buckwheat, potatoes and oats are coarse grains and are suitable for modern people to eat. But potatoes do not directly absorb water, toxins or fat. Coarse grains are rich in cellulose, and one cellulose molecule carries seven water molecules. Therefore, coarse grains occupy a large position in the gastrointestinal tract and stay for a long time, which is not only easy to feel full, but also conducive to cleaning the intestines and eliminating toxins. However, whether you get gastrointestinal cancer, rectal cancer or colon cancer cannot depend entirely on whether you eat buckwheat.

5. Is tomato heating very nutritious?

There are rumors that:

In the United States, almost every family grows and eats tomatoes. Tomatoes are not allowed for uterine cancer, ovarian cancer, pancreatic cancer and bladder cancer. But there is lycopene in tomatoes, which combines with protein and is surrounded by cellulose, so it is difficult to come out. Only when it is heated to a certain degree will it come out.

Expert opinion:

Both raw and cooked tomatoes are nutritious. Tomatoes contain lycopene, which is a kind of carotene. Because of its fat-soluble characteristics, it is more easily absorbed by the human body after cooking. However, the nutritional value of raw tomatoes should not be denied because the vitamin C content of raw tomatoes is richer than that of cooked tomatoes.

6. Black fungus instead of aspirin?

There are rumors that:

Now that the Spring Festival is over, heart attacks are one after another, and the age is getting smaller and smaller. There are two reasons, one is the hypercoagulable constitution with thick blood, and the other is high fat. Although myocardial infarction cannot be cured, it can be prevented. A doctor told you that eating can make blood less sticky and prevent myocardial infarction. But the consequence is fundus hemorrhage, and now many people have fundus hemorrhage. I advise you not to eat it. Auricularia auricula has been eaten in Europe.

Expert opinion:

Auricularia auricula is beneficial to regulating blood lipid and reducing blood viscosity. Regular consumption helps to prevent cardiovascular diseases, and its mineral content is also very rich. However, aspirin is the basic drug to prevent cardiovascular diseases, which is irreplaceable by auricularia auricula. Moreover, whether fundus hemorrhage is related to everyone's physique and whether the dosage is related to medication requires consulting a professional doctor.
