What is prostrate cancer?
Prostrate cancer occurs when cells in the prostrate gland grow out of control. Most prostate cancers are slow growing, however, there are cases of aggressive prostrate cancers. Prostrate cancer may cause pain, difficulty in urinating, problems during sexual intercourse or erectile dysfunction. Prostrate cancer is uncommon in men younger than 18, but becomes more common with advancing age. As prostrate cancer advances, it can spread to other parts of the body causing additional symptoms.
Prostrate cancer and diet
The high fat content of meat & dairy products, lead to an increase in hormone production and increased risk of prostrate and other hormonal cancers. Additionally, dairy products boost the amount of insulin-like growth factor (IGF-I) in the blood. While a small amount of IGF-I is normally in the bloodstream, several recent studies have linked increased IGF-I levels to prostrate and breast cancer. The high amount of calcium in milk depletes the body's Vitamin D, which also adds to cancer risk.
A vegan diet (vegetarian diet with no animal milk products) comprising high fiber goods such as grains, vegetables and fruits offer a measure of protection against breast cancer. Fibre greatly speeds the passage of food through the colon (effectively removing carcinogens), while also changing the type of bacteria present in the intestine reducing the production of carcinogenic secondary bile acids. Plant based foods are also naturally low in fat and rich in antioxidants and other anti-cancer compounds.
Scientific evidence: Prostrate cancer and diet
Research that has been conducted on the linkage between meat, dairy and prostrate cancer have found
- Significantly higher risks of developing prostrate cancer for consumers of meat and dairy products
- Animal fat, but not vegetable fat, associated with higher prostrate cancer risk
