Your diet may have more impact on your cancer risk than you might think, a new study has found. An estimated 80,110 new cancer cases among adults 20 and older in the United States in 2015 were attributable simply to eating a poor diet, according to the study, published in the JNCI Cancer Spectrum. "This is equivalent to about 5.2% of all invasive cancer cases newly diagnosed among US adults in 2015," said Dr. Fang Zhang ... who was first author of the study. "This proportion is comparable to the proportion of cancer burden attributable to alcohol," she said. The researchers evaluated seven dietary factors: a low intake of vegetables, fruits, whole grains and dairy products and a high intake of processed meats, red meats and sugary beverages, such as soda. "Low whole-grain consumption was associated with the largest cancer burden in the US, followed by low dairy intake, high processed-meat intake, low vegetable and fruit intake, high red-meat intake and high intake of sugar-sweetened beverages," Zhang said. You may protect yourself from cancer by avoiding ultraprocessed foods and instead choosing organic foods, research has shown. People who frequently eat organic foods lowered their overall risk of developing cancer, according to a study published last year in the medical journal JAMA Internal Medicine. Specifically, those who primarily ate organic foods were more likely to ward off non-Hodgkin lymphoma and postmenopausal breast cancer than those who rarely or never ate organic foods.
