Goji and Açai: Can these exotic berries improve your health?

They have miraculous curative properties. You’ve probably seen some of the claims. Superfruit juices are supposed to improve your energy, your sex life, your IQ, and your hairline. You’ll sleep better, lose weight, have clearer skin, and live to be 252. (No, really, one of the arguments for Goji juice is that a guy supposedly ate them every day and reportedly lived to be 252 years old.)

Not bad for fruit juice. No wonder it costs two bucks an ounce.

Now, notice that most of these claims made by people selling you the products. Although I think it has been adequately proven that these products have vastly improved the financial health of those selling them, there is very little research to support any of the health claims made by the manufacturers.

In fact, a recent search of the medical literature turned up just one study— a double-blind, placebo-controlled study conducted by a goji juice manufacturer. The researchers found that people consuming their product experienced “increased feelings of general well-being.” Personally, I think I could increase my feeling of general well-being more effectively by investing that extra $4 a day into my retirement fund.

The Bottom Line

I’ve tried açai juice and had goji berries. They’re perfectly tasty and I’m sure they’re good for you. But I’m not convinced any of these superfruits offer anything you can’t get from a healthy diet. In fact, because of the way antioxidants and phytonutrients work together, I think you’d be significantly better off eating a variety of fruits and vegetables (including goji and açai, if you like) than you would doing a daily shot of overpriced fruit juice.

But if the testimonials have convinced you and you have money to burn, you can make some Internet and multi-level marketers very happy. Then again, you could also send me a check for $120 every month. I bet it’ll make you feel better than you have in years. It’s worth a try, isn’t it
