A new Swiss study that suggests dietary cadmium may increase breast cancer risk is intriguing, but a strong body of evidence shows that women should not shy away from eating whole grains and other healthy foods to reduce their risk of this disease.

The study, published in Cancer Research, estimated the amount of cadmium almost 56,000 women were consuming. Cadmium is a metal found in low amounts in the soil, air and water.

Study researchers estimated the dietary cadmium by asking the women about their diet when the study began in 1987. They then used national data to estimate cadmium content for each food and divided the women into three groups of cadmium consumption: low, medium, and high.

Then the women were tracked for approximately 12 years.

When looking at only the women who consumed the highest amounts of whole grains and vegetables, the highest dietary cadmium group linked to a 21 percent increase in post-menopausal breast cancer compared to those in the lowest group.
