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.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
