Women who have diets rich in calcium can lower their likelihood of developing colorectal cancer. Their chances are even better if they take calcium supplements too. The study involved a survey of 45,000 cancer-free women. After being followed for 8.5 years, 482 of the participants were diagnosed with colorectal cancer.
The study's findings indicated that women who took 800 mg of calcium daily had a 26% lower risk of the disease, compared with women who took <530 mg. A 46% reduction rate was found in women who took at least 412 mg of calcium daily from dietary sources, as well as >800 mg in supplement form.
