High red meat consumption (1.6 servings per day) in early adulthood is
associated with a 22% increased risk for breast cancer, according to
longer-term follow-up from the Nurses Health Study II, published in BMJ.
Swapping out red meat for poultry or legumes one meal a day was
associated with significant risk reductions.
The authors conclude: “Consistent with the American Cancer Society
guidelines, replacement of unprocessed and processed red meat with
legumes and poultry during early adulthood may help to decrease the
risk of breast cancer.”
