Men who frequently eat red meat, lots of dairy products and treats have twice the risk of prostate cancer, US experts warn.
The study was conducted by a team from Harvard University's School of Public Health that compared eating habits and susceptibility to disease over a ten-year period among nearly 1,000 men.
A diet based on a limited intake of meat and butter, short heat treatment of dishes, more fruits and vegetables and more frequent consumption of fish and seafood reduces the same danger.
According to the authors of the study, the non-carbohydrate diet is associated with a reduction in serum insulin and insulin-like growth factor type 1 (IGF-1) - a protein that stimulates cell proliferation and is involved in cancer growth.
They point out that it is never too late to change one's diet and habits for the better.
Experts believe that the intake of low-calorie foods not only prevents the appearance of prostate cancer but also supports its effective treatment in people who are already ill.
It is already known that the "western diet" is an immediate danger to health and especially to the heart. In 35% of cases, it is the cause of cardiovascular problems.
Other negative health effects that reflect on general health and quality of life are decreased musculoskeletal status, measured by walking speed, and decreased cognitive abilities of the mind.
The negative effects of an unhealthy diet appear to be independent of factors such as smoking, alcohol consumption, and physical activity.
