What’s the best diet to follow to get healthy—should you go Paleo, low glycemic, low-carb, Mediterranean, or low-fat? For a paper released last month in the Annual Review of Public Health, Yale medical researchers David Katz and Samuel Meller surveyed the scientific evidence and decided … all of the above. Specifically, they found that all of these fad diets can be consistent with these basic principles:

The weight of evidence strongly supports a theme of healthful eating while allowing for variations on that theme. A diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention and is consistent with the salient components of seemingly distinct dietary approaches. [Emphasis added.]

But what about the Paleo diet, which encourages meat eating? 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 entirely consistent with the Paleo push for meat from pasture-raised animals, and brought to mind a study I wrote about late last year finding that cows fed on grass deliver milk with healthier fat profile than their industrially raised peers.

The Yale paper essentially cuts through the hype of various fad diets and affirms the koan-like advice put forward by author Michael Pollan in his 2008 book In Defense of Food: “Eat food. Not too much. Mostly plants.” In fact, the authors reference Pollan directly in the chart that summarizes their findings:

 

 

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
