Diet plays a significant role in the development of cancer

A study by Harvard Medical School showed which diets favor the development of cancer. The researchers can now use the results to demonstrate which foods people should rather omit and which contribute to a healthy diet and thus reduce the risk of developing cancer.

Unhealthy eating is an important factor

A recent study by Tufts University in Boston found that an unhealthy diet leads to thousands of cancer cases every year, which can usually be avoided simply by taking better care of what you eat. The results of the study were published in the English language journal "JNCI Cancer Spectrum".

In 2015, over 80,000 Americans got cancer from eating

In 2015, an estimated 80,110 new cases of cancer in adults over the age of 20 in the U.S. alone were due to people eating an unhealthy diet, the study's authors report. This corresponds to approximately 5.2 percent of all invasive cancer cases newly diagnosed in adults in the United States in 2015. This proportion is comparable to the proportion of cancer that can be attributed to alcohol.

Seven forms of nutrition were examined

For their study, the researchers assessed a total of seven nutritional factors: a low intake of vegetables, fruit, whole grains and dairy products, and a high intake of processed meat, red meat and sugary drinks. Low consumption of whole grains was associated with the highest rate of cancer in the United States, followed by low consumption of dairy products, high consumption of processed meat, low consumption of vegetables and fruits, high consumption of red meat and a high intake of beverages sweetened with sugar.

1. Broccoli substance as a cancer drug?

The latest study from Harvard Medical School, Boston found that broccoli can deactivate a gene that is involved in the development of various types of cancer. The results of the investigation were published in the English-language journal "Science".

Drinks that are too hot increase the risk of cancer

A recent study by the Tehran University of Medical Sciences found that consuming hot tea or coffee appears to have a massive impact on our risk of developing cancer. The results of the study were published in the English-language journal "International Journal of Cancer".

What types of cancer have been most common?

The researchers used a comparative risk assessment model that estimated the number of cancer cases associated with poor nutrition and how much nutrition plays a role in cancer in the United States. Earlier studies have shown that high consumption of processed meat increases the risk of colorectal cancer and high consumption of whole grain lowers the risk of colorectal cancer, the study authors explain. However, the new study quantifies the number and proportion of new cancer cases that result from poor nutrition at the national level. The researchers found that colon and rectal cancer were the highest number and the highest proportion of diet-related diseases with 38.3 percent.

Our diet is important for cancer prevention

More research is needed to determine whether a similar association can be observed in the United States for other periods. All in all, our diet remains one of the few changeable risk factors for cancer prevention, the researchers report. The results underscore the need to reduce cancer exposure by increasing the intake of important food groups and nutrients.

Danger from ultra-processed foods

So-called ultra-processed foods make up a growing part of global nutrition. For example, a 2016 survey found that 60 percent of the calories in the average American diet come from this type of food. You can protect yourself from cancer by avoiding ultra-processed foods and eating organic foods instead. A study published last year in the journal "JAMA Internal Medicine" found that the general risk of cancer is reduced in people who often eat organic food. (as)
