WASHINGTON (Reuters) - The risk of prostate cancer has been reduced or not in combination with plant foods, while the risk has been increased with animal-based foods, especially dairy products, according to a US study examining the association between plant and animal food consumption and prostate cancer risk.

The researchers provided five healthy foods to avoid prostate cancer:

Fish: Some fish, such as barracuda and mackerel, provide good fats that help prevent infections in the body. Omega-3 fatty acids (EPA and DHA) help prevent prostate cancer.

Cooked tomatoes: Lycopene in the walls of tomato cells is a powerful antioxidant, and cooking helps to relieve the bond, making it easier for the human body to access antioxidants and send it to the prostate. Tomato substitutes are tomato sauce, paste, juice, dried tomatoes and tomatoes cooked with olive oil.

Broccoli: Studies suggest that eating cruciferous vegetables can reduce the risk of prostate cancer. Broccoli contains sulforaphan, a chemical plant that is said to target and kill cancer cells. And Bok Choy, turnips, broccoli and Brussels sprouts.

Legumes: Legumes, such as beans, peanuts, and lentils, contain biologically active plant compounds known as phytoestrogen that may have cancer-fighting properties that can inhibit tumor growth in prostate cancer cells.

Pomegranate: Pomegranate is a rich source of antioxidants, and scientists believe that the antioxidants in pomegranate exclusively target prostate cancer cells and not healthy cells.

Prostate cancer begins when cells in the prostate gland, a small gland in the form of a nut, start only in men who produce fluid that forms part of the semen, to get out of control, the researchers said.

Symptoms of prostate cancer include frequent urination, weak or intermittent urine flow, a urge to urinate frequently at night, blood in urine, and blood in semen.
