the journal Nutrients, analyzed data from 2008 to see how
often 21 types of cancers occurred in 157 countries, 87 of which had
reliable cancer data.
William Grant, study author and director at the Sunlight, Nutrition, and Health Research Center in San Francisco, wanted to see whether these cancer rates correlated with various risk factors such as age, a country’s gross domestic product, and type of diet.
The high-quality data provided by the 87 countries showed that smoking and consumption of animal products were responsible for over half of all the cancer incidence rates.
Some trends were notably different for males and females; smoking affected males twice as much as eating animal products, while females showed the opposite pattern. Excluding lung cancer rates, smoking, and animal products accounted for 70 percent of the variation of cancer rates between countries.
Overall, 30 percent of cancer deaths, which was around 7.5 million in 2008, were caused by five “leading behavioral and dietary risks,” Grant explained in the study. These risks are high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco use, and alcohol use.
Animal products had a particularly strong correlation with various types of cancer because this kind of diet promotes body growth as well as tumor enlargement, Grant explained in a statement. Specifically, the kinds of cancer affected by this dietary factor include female breast, uterine, kidney, ovarian, pancreatic, prostate, testicular, thyroid, and multiple myeloma.
Grant noted that Japan serves as an example of how alteration in diet can affect both body growth and the incidence of cancer.
While the older Japanese population is considerably shorter than westerners, the younger generation has become just as tall due to an increase in the number of calories that they derive from animal products, which is typically a more western diet.
As a result, the types of cancers that were more common in Western countries have now been on the rise for the past two to three decades in Japan. CONTINUE READING
