Here's How Many US Cancer Cases Are Tied to Unhealthy Diets

Avoiding two main diet mistakes might help us to stave off our cancer risk, according to a new study.

While cancer-fighting scientists have warned us off everything from bacon to too-hot beverages, it can be hard to identify which foods we should be introducing into our diet, instead.

The investigators also looked at specific eating habits linked with cancer risk.

The Tufts University study found that poor diets cause about the same number of cancer cases as alcohol consumption does in the United States.

"Our findings underscore the opportunity to reduce cancer burden and disparities in the United States by improving food intake", Zhang said.

More than 80,000 cancer cases diagnosed each year in the US may be tied to an unhealthy diet, according to a new study.

The study, conducted by the Friedman School of Nutrition Science and Policy at Tufts, analyzed cancer diagnoses among USA adults from 2015 along with data from two national surveys on Americans' diets to determine how many cases were linked to diets low in vegetables, fruits, whole grains and high in processed sugar, sugary beverages and red meats.

A new study has found that a poor diet could lead to a higher risk of cancer.

Celebrities are increasingly talking about different cancer symptoms in an effort to raise public attention around their conditions. That was followed by cancer of the mouth, pharynx and larynx, for which dietary factors accounted for about 14,400 cases; uterine cancer, for which 3,165 cases were tied to diet, and postmenopausal breast cancer, for which 3,060 cases were tied to diet.

"This proportion is comparable to the proportion of cancer burden attributable to alcohol", she said. Those estimations were made using diet-cancer associations found in separate studies.

Men, middle-aged adults (aged 45 to 64), and black and Hispanic people had the highest rates of diet-associated cancers, compared with other age, gender, or racial/ethnic groups, according to the report.

Method: The researchers reviewed data from the National Health and Nutrition Examination Survey on the dietary intake of US adults between 2013 and 2016. The model also included data from the World Cancer Research Fund on the link between diet and cancer.

The team defined optimal dietary intake based on the dietary distributions associated with the lowest disease risk as assessed by the World Health Organization's Global Burden of Disease (GBD) project.

The researchers caution that self-reported dietary intake data is subject to measurement error. In addition, diet-cancer risk estimates may differ by sex, age, race/ethnicity and other modifiers.
