Differences between Western and Japanese diets may explain why prostate cancer is 10 times more common in the United States than in Japan, according to a study.
Researchers noted that the risk of prostate cancer increases in Japanese men who move to the United States and adopt the high-fat Western diet, typically within one generation.
The study involved 50 men who had had a cancerous prostate gland removed. Half of the men lived in Japan and the other half were born in the United States to Japanese parents and resided in Los Angeles.
While the men shared similar genetic roots, their diets were significantly different. The Japanese-American men ate less soy and more animal fat than the native Japanese men. They also had more body fat and higher triglyceride levels.
Although it has been suggested that soy may protect against prostate cancer, soy didn't protect the men in the study, researchers noted.
Researchers analyzed the prostate cancer samples from the two groups of men. While the samples looked the same, the DNA was arranged differently, possibly because of a gene-nutrient interaction.
The differences between the samples may be a result of diet, according to researchers.

While this study only addresses prostate cancer, previous research has strongly suggested that the causes and treatments of prostate and breast cancer are very similar.
Fortunately, there are many simple, inexpensive and practical options for these types of cancers as I reviewed last month when I commented on prostate cancer.
It is wise to not implement aggressive traditional medical strategies for this problem as prostate cancer is a relatively slow growing cancer and is easy to control if caught early.
Here is a list nutrients and techniques that are likely to prevent prostate cancer, the number one cancer in men:
