What role does our diet play in cancer development?
According to a new study, our diet may have a greater impact on our cancer risk than previously thought. Researchers found that every year thousands of people get cancer because they eat junk food.
A recent study by Tufts University in Boston found that unhealthy diets lead to thousands of cancers every year, which can usually be avoided because people are more attentive to what they eat. The results of the study were published in JNCI Cancer Spectrum.
More than 80,000 Americans have become cancerous in 2015 due to their diet
It is estimated that in 2015 there were only 80,110 new adult cancer cases in the US from the age of 20 due to people feeding unhealthily. This represents approximately 5.2% of all newly diagnosed cancers diagnosed in the US in 2015. This proportion is comparable to that of alcohol-induced cancer.
Seven forms of nutrition were studied
The researchers evaluated a total of 7 dietary factors for their study: low intake of vegetables, fruits, whole grains and dairy products, as well as high intake of processed meat, red meat and sweet drinks. Low consumption of whole grains was associated with the highest incidence of cancer in the US, followed by low milk consumption, high consumption of processed meat, low intake of vegetables and fruits, high consumption of red meat and high meat intake. sugar-sweetened drinks.
What types of cancer were particularly common?
The researchers used a comparative risk assessment model that estimated and evaluated the number of cancer cases in terms of dietary impact on cancer in the US. Previous studies have shown that high consumption of processed meat increases the risk of colorectal cancer and low consumption of wholegrain sugar reduces the risk of colorectal cancer, the authors of the study explain. However, the new study quantifies the number and proportion of new cancers due to poor diet at national level. Researchers found that colorectal cancer, 38.3 percent, represents the highest and highest proportion of nutrition-related diseases.
Our diet is important for cancer prevention
Further investigation is needed to see whether similar associations occur in the US for other periods. All in all, our diet remains one of the few modifiable risk factors for cancer prevention. The findings highlight the need to reduce cancer burden by improving the intake of key food and nutrient groups.
Hazards from highly processed foods
So-called ultra processed foods are a growing part of the global diet. For example, a 2016 study found that 60% of calories in the average American diet come from this type of food. You can protect yourself from cancer by avoiding ultra-processed foods and instead choose organic foods. A study published last year in the JAMA Internal Medicine found that people who often eat organic food reduce the overall risk of cancer. (As)
