Ingesting higher levels of cadmium, a metal found in fertilizers, may be linked to an increased risk of breast cancer, a new study from Sweden suggests.
The results showed that postmenopausal women with a relatively high daily dietary cadmium intake had a 21 percent increased risk of breast cancer.
The major sources of cadmium in the diets of women in the study were foods that are generally healthy — whole grains and vegetables. These accounted for about 40 percent of the cadmium consumed.
The reason for the link may be that cadmium can cause the same effects in the body as the female hormone estrogen, the researchers said…
The researchers said they are concerned that cadmium is found in foods we consider healthy. The metal is well-absorbed by farmed plants, and fertilizers used to help grow our fruits, vegetables and grains contain cadmium.
The researchers noted that whole grains and vegetables, which were found to contain the most cadmium, have many beneficial nutrients— some that likely counteract the negative effects of the toxic medal.
