Prevent Prostate Cancer by Eating More Vegetables, Less Meat
by Teresa Manafaia
(NaturalNews) Prostate cancer is a serious health problem affecting a high percentage of men in industrialized western societies. The risk factors for prostate cancer mortality have already been identified and published (Grant, 2002, in Journal of Nutritional and Environmental Medicine).
According to this author, the consumption of vegetable protein was found to be an important risk-reduction factor. The high inverse relation between prostate cancer mortality and the consumption of vegetable protein is probably due to the high isoflavonoids and lignan content in foods such as pulses (beans) and whole grains. Where else can we find protein in vegetables? The highest protein content comes in legumes, but also in nuts and seeds! In fact, nuts and seeds are also rich in essential fatty acids, which can protect you against inflammation. It is also known that a high consumption of vegetable products in general, as a fraction of total energy (not only protein rich vegetables), is inversely related with prostate cancer mortality.
In contrast, a high consumption of animal products as a fraction of total energy, animal fat, the non-fat portion of milk, and added sugar, was found to be a risk factor for prostate cancer mortality (Grant 2002).
As a result of these findings, the recommendations are simple: to eat less fatty meat and avoid processed meat products (due to their high content of animal fat and preservatives). Cancer growing preservatives are present in foods such as sausages, salami, hamburgers, etc.
Milk and sugar (including refined cereals) increase your insulin response; avoid these kinds of food, so you can maintain a healthy metabolism. They may enhance prostate cancer development and subsequent mortality.
Vitamin D also protects against cancer. Healthy sun exposure, without sunscreen, can boost your vitamin D production. This can be done on the first and last hours of sunlight � this is not dangerous and helps in melatonin production regulation. Vitamin D supplementation is also an interesting strategy to consider.
Finally, exercise has already been identified as a cancer protector. Walking vigorously, at least 30 minutes everyday, and performing functional weight training every 2 days, may improve your cardiovascular resistance, enhance your insulin sensibility and boost your immune system!
