Today's Lunch Break:
Early soy diet may protect against breast cancer
It has long been known that breast cancer rates in Asian women are lower than average but that the difference quickly diminishes in subsequent generations after immigration to the West (suggesting a factor other than genetics). The study above lays out strong evidence pointing to childhood soy intake as a major protective factor[1].
A glass of wine a day, according to conventional wisdom, is good for you.
Not so fast. In their "Memo to the Media," the Journal of the National Cancer Institute (JNCI) has some grim news for the light drinker: Million Women Study Shows Even Moderate Alcohol Consumption Associated with Increased Cancer Risk. With a cohort of over a million women, the study harnesses some considerable statistical power; the odds ratio is arguably a modest figure but still impressive: researchers found that "low to moderate alcohol consumption among women is associated with a statistically significant increase in cancer risk and may account for nearly 13 percent of the cancers of the breast, liver, rectum, and upper aero-digestive tract combined." Low to moderate alcohol consumption means ~1 drink per day; the type of alcohol (wine vs. spirits, for example) made no difference in the final outcome.
