New Study Finds Nutritional Benefit to Eating Organic Food

An analysis of 343 peer-reviewed studies on the nutritional content of organic versus non-organic food concludes that organic produce does indeed contain more nutrients.

What's the Latest?

An analysis of 343 peer-reviewed studies on the nutritional content of organic versus non-organic food concludes that organic produce does indeed contain more nutrients. The meta-study was led by Carlo Leifert, who studies ecological agriculture at Newcastle University, UK, and found that higher levels of "nutritionally desirable" antioxidants are present in organic food. "For example, phenolic acids, flavanones, and flavonols were 19%, 69%, and 50% higher, respectively, in organic produce compared to its conventional counterparts, says the study, which was published today in the British Journal of Nutrition."

What's the Big Idea?

Prior to this study, no significant nutritional benefit had been found between organic and conventionally grown food. "A 2009 review...looked at total of 67 studies on the nutritional content and health effects of organic versus conventional produce. This study found no clear nutritional benefits of organic produce over conventionally grown food. Likewise, a review of 237 studies published the Annals of Internal Medicine in 2012 also found no significant differences." Authors of the most recent analysis argue that those papers were too selective in the kinds of studies they were willing to review.

'Upstreamism': Your zip code affects your health as much as genetics

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."

Sponsored by Northwell Health

  • Patients from low-income neighborhoods are most at risk of negative health impacts.
  • Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.

Meet the Bajau sea nomads — they can reportedly hold their breath for 13 minutes

The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.

Culture & Religion
  • The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
  • Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
  • Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
