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 on Wednesday.
“This is equivalent to about 5.2% of all invasive cancer cases newly diagnosed among US adults in 2015,” said Dr. Fang Fang Zhang, a nutrition and cancer epidemiologist at Tufts University in Boston, 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.
The study included data on the dietary intake of adults in the United States between 2013 and 2016, which came from the National Health and Nutrition Examination Survey, as well as data on national cancer incidence in 2015 from the US Centers for Disease Control and Prevention. (emphasis mine)
So, we’re dealing here with the usual food recall questionnaires, which as we all know are a little less accurate than long-range weather forecasting. Additionally, there appears to be the common bias towards the conventional “healthy diet” of whole grains, vegetables, fruits, and low meat consumption. They fail to notice or address the healthy person confounder.
