Fruits can prevent heart disease, especially persimmons. Western proverb says: an apple a day keeps the doctor away. However, when it comes to preventing cardiovascular sclerosis, apples have to "candidly admit defeat" in front of persimmons. According to the determination, persimmon contains a lot of fiber, minerals and carbolic acid (an antioxidant), which is an element to prevent arteriosclerosis. The fiber content of persimmon is 1 times that of apple. The contents of carbolic acid, potassium, magnesium, calcium, iron and manganese are much higher than those of apples. Only the contents of copper and zinc are slightly lower than those of apples. Therefore, middle-aged and elderly people eat more persimmons moderately, which is of great benefit to the heart.

2, tomatoes: raw antithrombotic.

Tomato has remarkable antithrombotic effect and is of great value in preventing diseases such as cerebral infarction and myocardial infarction. In order to give full play to this role, tomatoes are best eaten raw. Nutritionists suggest that you can insist on eating 1 tomato every day; If you drink tomato juice, it is best not to exceed 250 ml a day and try not to put salt. Every morning, when there is insufficient water in the body, blood is easy to coagulate. This is the best time to eat tomatoes raw or drink tomato juice. Middle-aged and elderly people, especially patients with cardiovascular and cerebrovascular diseases, must not miss it.

3, bone soup: often drink to delay aging

With the increase of age, the function of human bone marrow to make blood cells gradually declines. At this time, people need to take mucin from food to enhance the ability of bone marrow to make blood cells. And bones propelled by mucin-like foods. Take pig bone as an example, mash it, and stew it with 1 part bone and 5 parts water at the ratio of 1 ~ 2 hours, so that the bone marrow liquid containing mucin and collagen can be dissolved as much as possible, and vegetables can be added to bone soup for eating. As long as you persevere, you can delay the aging speed of people.

4. Oranges: Prevention of Female Cholecystitis

In a survey of 13000 men and women, it is found that eating more oranges rich in vitamin C is helpful for women to prevent cholecystitis. Cholecystitis has the phenomenon of "valuing women over men", because estrogen can accumulate more cholesterol in bile, form gallstones, and then induce inflammation. Oranges are rich in vitamin C, which can inhibit the conversion of cholesterol into bile acids, reduce the neutralization of fat-decomposing bile and cholesterol, and reduce the chance of combining the two to form gallstones. Therefore, experts advise women to eat more fresh oranges to protect their gallbladder from stones and even inflammation.

5, beer: prevention of cataracts

Recently, Canadian scientists suggested that beer can prevent cataracts. This effect of beer is mainly due to the antioxidant substances in beer, which can protect cell mitochondria, and mitochondria can convert glucose into energy, which plays a key role in the pathogenesis of cataract. Of course, beer can't be abused under the pretext of preventing eye diseases, because beer is also wine, and drinking too much will damage organs such as liver and brain, leading to serious consequences.

6, wine: a "panacea" to prevent and treat stomach diseases.

Researchers at a hospital in San Francisco, USA, said that wine has a strong bactericidal ability and can kill Helicobacter pylori, which causes stomach diseases. The researchers put Helicobacter pylori into wine and found that the bacteria would not reproduce for 20 minutes. The expert's explanation is that in the process of wine brewing, a substance called polyphenols will be produced, and it is this substance that plays a bactericidal role.

7. Auricularia auricula: preventing urethral stones.

If patients with urethral calculi can insist on eating auricularia auricula every day, the pain will soon disappear, and the stones will become smaller or even discharged after 10 ~ 14 days, which is a new clinical discovery of doctors. The secret is that the fermentation factors and plant alkaloids in auricularia auricula can stimulate gland secretion, moisten the pipeline and promote stone discharge; At the same time, the minerals contained in Auricularia auricula can react with the chemical components in the stones, so that the stones are denuded and reduced, thus speeding up the excretion of stones.

8. Cherry: Prevention of arthritis

American researchers have observed that eating cherries or drinking cherry juice often can prevent arthritis and gout. Patients who already have arthritis eat cherries, which helps to reduce the swelling of the affected joints, thus relieving pain. The researchers explained that some substances contained in cherries are more effective than aspirin in preventing and treating inflammation such as arthritis and gout. Eating 20 cherries a day can inhibit the pain caused by arthritis and gout.
