Paying extra for those tasty organic fruits and vegetables may cost you: A new study suggests that eating can help you avoid cancer diagnosis.
People who consumed the most organic foods had a cancer risk of 25% lower than those who received the least.
In particular, more organically grown food was associated with a reduced risk of postmenopausal breast cancer of 34%, a 76% reduced risk for all lymphomas and 86% lower risk for non-Hodgkin lymphoma, said leading researcher Julia Baudry. She is a researcher at Sorbonne's Paris Cite Research and Epidemiology and Statistics Finland.
"If our findings are confirmed, the consumption of organic food can contribute to the prevention of cancer," Baudry said, although the study did not directly indicate a cancer risk.
Eat more fruits and vegetables
But people should not stop eating fruit and vegetables if they can not afford the more expensive organic farming options.
Filling fruit and vegetables is known to reduce the risk of chronic illness and cancer, regardless of whether they are organic, Baudry and other experts say.
Mark Guinter, a PhD in the American Cancer Society, said: "More important than anything is to make sure you use your fruit and vegetables, avoid red and processed meat, and eat whole grains."
Guinter added, "If people are interested in changing their diet or buying foods that are known to help prevent cancer, they would certainly have the means to do it, not just buying organic products."
In this study, Baudry and his colleagues analyzed data from nearly 69,000 people involved in ongoing French research on nutrition and health associations.
Participants completed questionnaires on the consumption of organic products. These include fruit and vegetables, dairy, meat and fish, eggs, breads and other foods.
They also completed annual questionnaires on their state of health, including cancer cases, and were followed for an average of 4.5 years.
Researchers found the association between organic food and cancer risk, even if other cancer risk factors were taken into account.
"We are discussing a variety of factors that may be involved in the relationship," Baudry said. "[These included] sociodemographic, socio-economic and lifestyle factors as well as the family of cancer or a healthier diet for nutrition and nutrition. Controlling these factors did not substantially change the results. "
Lower levels save
Organic food is grown without pesticides, fertilizers and other chemicals. Studies have shown that people who eat organic products are lower pesticide residues in their urine, he said.
Baudry said that "exposure to pesticides has been associated with a higher risk of cancer".
In particular, Guinter said that this study supports the results of British research, which also found the combination of organic food consumption and lower risk for non-Hodgkin lymphoma.
"Whenever you see a result that is repeatedly so, you will find it more credible, with a very biological credibility guaranteeing it," Guinter explained.
Dr. Frank Hu, Nutrition Director at Harvard TH Chan School of Public Health, says animal testing has shown that pesticides can increase DNA damage that can increase cancer risk. Chemicals can also interfere with hormone activity. Dr. Hu is also the leading writer of the delivery delivered with the new study.
But Guinter and Dr. Hu noted that there was not enough human evidence yet to establish new dietary recommendations.
People should eat properly and maintain a healthy weight through diet and exercise to prevent cancer, Dr. Hu said. Cutting alcohol also helps.
"In principle, increasing the consumption of fruit and vegetables, either traditional or organic, can improve overall dietary quality and reduce the risk of chronic diseases such as cancer," said Dr Hu.
