The prostate is a small gland in the male reproductive organs. The prostate is located near the bladder. Many men are affected by prostate disorders. As you get older, it’s good for men to be aware of signs of prostate cancer. According to the American Cancer Society, one in every seven men diagnosed with prostate cancer and this cancer is the second leading cause of cancer deaths in men in the United States. In 2015, 27,540 deaths were caused by prostate cancer.  However, some precautions, such as changing diet and lifestyle and studying family medical history, can reduce the risk of prostate cancer.
Some things you can do
Increase consumption of vegetables and fruits.
Eat jam and bread made from cereal made from white flour. Eat at least five servings of vegetables and fruits every day. Also eat foods that are rich in lycopene, a powerful antioxidant, such as tomatoes and red peppers.
The content of lycopene makes vegetables and fruits turn red. Lycopene has been proven effective in preventing cancer. So, in general, the darker and brighter the red colors of the vegetables and fruits you eat, the better.
There is no definitive guide to how much lycopene needs to be consumed every day. However, research shows that to get the benefits of lycopene, people need to get enough lycopene by consuming foods that contain the substance throughout the day.
Eating Brassicaceae vegetables, such as broccoli, cauliflower, cabbage, Brussels sprouts, mustard sprouts, and kale, are also effective in preventing cancer. Some controlled studies show that increasing consumption of Brassicaceae vegetables triggers a reduced risk of prostate cancer even though the evidence used is only associative at this stage.
Eat only certain types of protein.
Reduce consumption of red meat, such as beef, pork, lamb, and mutton. Also limit consumption of processed meat, such as sandwiches and hot dogs.
Instead of red meat, eat fish rich in omega-3 acids, such as salmon and tuna. Eating fish of this type improves prostate health, the heart and the immune system.
Research on the effectiveness of consuming fish to prevent prostate cancer is largely based on correlative data and the fact that men in Japan eat large amounts of fish and only a few have prostate cancer.
Researchers are still debating whether increased fish consumption and reduced risk of prostate cancer have a causal relationship.
Nuts, skinless chicken and eggs are also a source of healthy protein.
Increase soy consumption.
Soybean content, which is found in various vegetable dishes, is effective in preventing cancer. Foods that contain soy include tofu, soybeans, soy flour, and soy powder. Using soy milk, instead of cow’s milk, to eat cereal or drink coffee is one way to increase soy consumption.
Recent research shows that soybeans and some soy products, for example tofu, are effective in preventing prostate cancer. However, not all soy products, for example soy milk, have this property. In addition, there are no definitive guidelines regarding the amount of soybeans that need to be consumed to prevent prostate cancer.
Reduce consumption of alcohol, caffeine, and sugar.
Caffeine consumption does not have to be stopped completely, it just needs to be limited. Drink only 120-240 ml of coffee per day. The same thing applies to alcohol; drink alcohol only on special occasions and only as many as two small glasses per week. 
Don’t consume sugary drinks, which sometimes also contain caffeine, such as soda and fruit juice. This type of drink contains almost no nutrients.
Reduce salt consumption.
The best way to reduce salt consumption is to eat meat, dairy products, vegetables, and fresh fruits. Don’t eat frozen, canned, and packaged foods. Salt is often used to preserve food. Therefore, packaged foods usually have a high salt content.
When shopping at a convenience store, buy fresh food, which is usually located at the edge; packaged and canned foods are generally located in the middle aisle.
Read and compare food labels. Food manufacturers are now required to put on food labels the amount of sodium contained in the product as well as the percentage of the recommended daily amount of sodium intake.
The American Heart Association recommends that US citizens consume no more than 1,500 mg of sodium per day.
Eat good fats and avoid bad fats.
Limit consumption of saturated fats derived from animals and dairy products. Eat foods that contain healthy fats, such as olive oil, nuts, and avocados. Animal products that have a high fat content, such as meat, butter, and lard, have been shown to increase the risk of prostate cancer.
Don’t eat fast food and processed foods. Both of these foods usually contain partially hydrogenated fats (trans fats), which are very bad for your health.
