Foods that help lower a person's prostate-specific antigen, or PSA, levels include low-fat foods, vegetables, cooked tomatoes and tomato-based foods, reports HowStuffWorks. Pomegranate juice also helps combat prostate cancer because it contains plenty of phytochemicals, which help control the growth of cancer.
It is important to reduce intake of meat, fatty foods and milk, as consumption of these foods increases a person's risk of prostate enlargement, explains HowStuffWorks. Individuals who eat lots of animal-based and fatty foods on a regular basis are prone to the stimulation of cancer cell growth. Studies suggest that a vegan diet may help reduce PSA levels in patients diagnosed with the condition.
Tomatoes and tomato-based foods contain the antioxidant lycopene, and cooking tomatoes releases the antioxidant and allows the body to absorb it more easily, states HowStuffWorks. A Harvard University study revealed that men who ate at least 10 servings of tomatoes had a significantly lower risk of developing prostate cancer. Lycopene can also decrease the PSA count in patients with advanced prostate cancer.
In addition to changing a person's diet, a regular exercise regimen involving meditation, yoga and mild aerobic exercise possibly helps reduce the PSA levels in prostate cancer patients, according to HowStuffWorks. Aerobic exercise is essential in managing weight issues, which trigger hormone production that leads to prostate problems.
