New research has found that eating organic food could lower your risk of cancer.

Yep, it might actually be worth spending that extra $2 for organic spinach at the supermarket.

A new French study of almost 70,000 adults (of which 78% were female) has found that those who consumed organic products most frequently had 25 per cent fewer cancers than those who never ate organic.

The study, published in JAMA Internal Medicine, followed the adults for five years. Those who ate the most organic fruit, vegies, dairy products, meat and other foods had a significant drop in the incidence of cancers such as lymphomas.

According to the New York Times, the magnitude of the findings surprised the study authors.

“We did expect to find a reduction, but the extent of the reduction is quite important,” said Julia Baudry, the study’s lead author and a researcher with the Center of Research in Epidemiology and Statistics Sorbonne Paris Cité of the French National Institute of Health and Medical Research.

While the study does not prove an organic diet will reduce cancer, Baudry said it strongly suggested “that an organic-based diet could contribute to reducing cancer risk.”

The study concluded that “promoting organic food consumption in the general population could be a promising preventive strategy against cancer.”

A commentary accompanying the study, by Harvard nutrition experts, cautioned that more long-term studies are required to confirm the results.

It is important that everyone eats enough fruit and vegetables – organic or not – if they want to prevent cancer, according to Dr. Frank B. Hu from Harvard’s T.H. Chan School of Public Health.

There has only ever been one other large study that looked at organic food consumption in regards to cancer. A 2014 British study found a significantly lower risk of non-Hodgkin’s lymphoma among women who said they usually or always ate organic food, but it also found these same women had a higher rate of breast cancers and no overall cancer reduction.

Whatever the research, it is clear that more people than ever are reaching for organic foods.

The Australian Organic Market Report 2018 found that Australia’s organic food industry is worth $2.4 billion.

The country’s number of certified organic processors has increased by 23% since 2016 and the total value of the industry has grown 88% since 2012.

Organic products are generally grown without synthetic pesticides, fertilisers, irradiation or chemical food additives and without routine use of antibiotics or growth hormones. Organic livestock are offered freedom of movement and access to the outdoors and are fed pesticide- and animal byproduct-free organic feed.
