Eat What You Want, But Eat Fresh

This is interesting. Yesterday I wrote a post suggesting that we should all try to eat more fresh food and less processed food, but that otherwise it didn’t matter much what kind of diet you followed. (Within reason, of course.) This was based solely on my intermittent reading of food research over the years, not on a specific rigorous study. Today, however, fellow MoJoer Tom Philpott tells me that there is indeed a rigorous study that backs this up:

Over the past decade, there has been a bounty of research on the ill effects of highly processed food. And when Yale medical researchers David Katz and Samuel Meller surveyed the scientific dietary literature for a paper in 2013, they found that a “diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention.”

Interestingly, Katz and Meller found that as long as you stick to the “minimally processed” bit, it doesn’t much matter which diet you follow: low-fat, vegetarian, and Mediterranean have all shown good results. Even the meat-centered “paleo” approach does okay. The authors conclude the “aggregation of evidence” supports meat eating, as long as the “animal foods are themselves the products, directly or ultimately, of pure plant foods—the composition of animal flesh and milk is as much influenced by diet as we are.” That’s likely because cows fed on grass deliver meat and milk with a healthier fat profile than their industrially raised peers.

Now, Tom is optimistic that processed food is losing its allure as Americans migrate more and more to fresh foods. I can’t say that I share this optimism, but I hope he’s right. There’s nothing wrong with a potato chip or a can of soup here and there (everything in moderation!), but a steady diet of processed food really is something worth avoiding.

In-depth journalism that investigates the powerful takes real money and is so damn important right now.But it doesn’t take a Mother Jones investigation to know that billionaires and corporations will never fund the type of reporting (like they do politicians) we do that exists to help bring about change. Instead, our mission-driven journalism is made possible by people power, and has been for 46 years now since our founding as a non-profit.

In “TITLE TK” Monica Bauerlein writes about the perilous moment we’re in, and why it’s so important that we raise $325,000 by the time November’s midterms are decided so we can be ready to throw everything we have at the big issues facing the nation no matter what happens.
