 A plant-based diet protects against chronic oxidative stress-related diseases, but which plant foods are the best? Berries are the healthiest fruits, and this study analyzes more than 100 different berries and berry products. Just to give a sense of scale, this is how many antioxidants are in America's two most popular fruits, bananas, and apples. Now, the most popular fruit in the world is mango, which does better, but none of these are a match for the berries. Here's a cup of strawberries, blueberries, raspberries, cranberries, and blackberries. Now, that's pretty much where most of us have to leave it, unless you have access to crowberries, or, whoa, dog roseberries, but getting back to what we can actually buy in a store, you'll see I keep changing the scale here on the right. What about goji berries? I'll cover those in an upcoming video on dried fruit. What about a shot of Tahitian Noni juice? Doesn't even make it up to banana. And sadder than even that, a cup of green grapes, which technically are berries, but nutritionally are the wonderbread of the fruit kingdom. What about acai berries? There was actually an acai study that caught my eye last year in the Journal of Experimental Gerontology. Acai fruit pulp improves survival on a high-fat diet. I thought, how interesting, until I reread the title more closely, acai improves the survival of flies on a high-fat diet. Why would you even want to do that? I imagine the researchers out collecting flies from some fast food dumpster or something. Unfortunately, acai wasn't tested in this study. Hopefully they'll come back next year and make it the 3,140th. In the meanwhile, I encourage everyone to eat berries every day. To always have bags of frozen berries in their freezer, whichever ones you like, but as we learned in this study, we can get more than twice the bang for our buck, choosing blackberries, for example, over strawberries.
