Prostate cancer is a common malignant tumor of the genitourinary system, and its incidence has significant geographical and ethnic differences. Worldwide, the incidence of prostate cancer is higher in developed countries in Europe and the United States and lowest in Asia and North Africa. In the United States, prostate cancer is the first in incidence and the second in mortality, with approximately 30,000 deaths from the disease each year. The incidence and mortality rates of prostate cancer in Asian countries are about 10 times lower than those in the United States, with Japan and China in particular having the lowest rates. It is now believed that the daily dietary habits of Asians are one of the important factors for the low incidence of prostate cancer in Asians. Recently, with the rapid development of China’s economy, the improvement of living standard, the change of diet structure, the gradual aging of the society and the improvement of treatment technology, the incidence of prostate cancer in China is also showing a significant increase. It is a matter of great concern how to prevent prostate cancer in daily life.
The general principle of diet is a low-fat diet based on fresh vegetables, fruits, soy products and aquatic products.
I. It is recommended to eat more of the following foods.
1, eat more cruciferous vegetables
The study found that men who ate more cruciferous vegetables were less likely to get prostate cancer.
2. Consume more legumes
Researchers point out that the incidence of prostate and bowel cancer is much lower in Asian regions where more legumes are consumed than in Europe and the United States. The chances of prostate cancer are 26% lower for those men whose daily diet often includes legumes than for those who do not eat legumes often.
3, eat more tomatoes, carrots and watermelon
Tomatoes and watermelon contain a lot of lycopene, which is reported to reduce the incidence of prostate cancer by 32%. An inch-long slice of watermelon contains lycopene equal to four tomatoes. Carrots have a lot of beta carotene which helps your body absorb the lycopene in tomatoes.
4, eat more fruits high in vitamin C, such as oranges, etc.
Studies have found that a diet high in vitamin C reduces the chances of developing prostate cancer by 23%.
5. Drink green tea every day
The scientists in the United States have recently discovered that green tea contains a highly effective bioactive substance “tea polyphenols”, which can not only stop the proliferation of cancer cells, but also inhibit the growth of blood vessels next to cancer cells, which can greatly reduce the rate of spread of prostate cancer. The results of this research were published in the December 2004 issue of Cancer Research, the leading international journal of biology. In addition to the discovery that green tea can inhibit the spread of prostate cancer, in recent years, related scientists at home and abroad have found after several studies that green tea has a certain preventive and therapeutic effect on a variety of cancers.
6.Eat more fish
A 30-year follow-up survey conducted by the Karolinska School of Medicine in Sweden showed that people who eat fish regularly are not prone to prostate cancer. The researchers of the medical school conducted a 30-year follow-up survey of 6,000 men in Sweden from 1967 to 1997. The results showed that people who never ate fish were two to three times more likely to develop prostate cancer than those who ate fish regularly. The researchers believe, after preliminary analysis, that a special substance contained in the body of fish has the effect of preventing prostate cancer.
7, proper supplementation of selenium
One chicken breast is enough to provide you with the selenium you need for the day. According to one source, men who consumed adequate amounts of selenium for 41 consecutive years were 63% less likely to die from prostate cancer. Whole wheat tortillas contain selenium and lots of fiber. Canadian researchers have found that foods containing sufficient soluble fiber can lower PSA levels in the body.
Second, the following foods are recommended to be eaten sparingly.
1, eat less red meat, animal fats
There is a close relationship between high fat intake, obesity and the burning process of food and the occurrence of prostate cancer in the Western-type diet.
2. Drink less milk
An 11-year follow-up survey of 2,10,000 men found that the risk of prostate cancer was 32% higher for those who drank more milk than for those who did not. This finding shows a link between high intake of dairy products and prostate cancer. The high daily intake of calcium through dairy products can suppress the level of vitamin D in the blood. It is now known that the risk of prostate cancer formation can be reduced if high levels of vitamin D are maintained in the body.
Lastly, we will discuss the following considerations in daily life.
1. Proper physical activity and maintaining a healthy weight
The survey found that men who swim for 30 minutes a day are much less likely to develop advanced prostate cancer. Scientists say that swimming can improve resistance to disease, promote local blood and lymph circulation in the prostate, and help inflammation in the prostate to subside. In addition, swimming can help prostate cancer patients better absorb drugs, thus improving their efficacy, and is good for symptoms such as neurological disorders and nervous exhaustion.
Scientists recommend that men should keep swimming for about half an hour a day. However, men who engage in relatively intense sports such as cycling and gymnastics are 30% more likely to develop prostate cancer than the former. So try to avoid doing competitive sports.
2, more sunlight
The epidemiological survey also found that more elderly men living in the northern latitudes died of prostate cancer. This is related to the low level of vitamin D in their bodies.
It is best to have 10 minutes of sunlight every day to help the body naturally produce enough vitamin D.
3. Don’t smoke and drink a lot of alcohol
The most important thing is to have a good amount of red wine to prevent prostate cancer.
