Not long ago, my local grocery store added a new cold case display. Tucked between the coconut milk and the canned beans, a refrigerator is now filled with fermented beverages claiming better digestive health.

Next to them are bottles of expensive probiotics in specialized formulas for kids, men, and women—all vowing to help prevent or treat some illness or other. Add to these the myriad products promising more energy, a healthier heart, and less inflammation, and suddenly the food market can look a lot like a pharmacy. But do probiotics really work? We put that question to experts here at Johns Hopkins. In “The Garden in Your Gut” [p. 26], you’ll learn about the fascinating discoveries happening around the human microbiome.

Speaking of putting good things in your body, in this issue's "Expert Advice"? [p. 8], dietitian Susan Oh gives tips for fostering healthy eating habits in your kids; neurologist Lee Peterlin offers ideas for mitigating migraine headaches in "10 Things"? [p. 11], including adding healthy late night snacks to your diet; and  endocrinologist Kendall Moseley explains how much calcium  we need to keep our bones healthy in "Survey"? [p. 21].

And remember when we were going to use corn, leftover kitchen grease, and other comestibles to run our cars? Research-ers are still pursuing the idea, and some commercial flights are now fueled by food. In "Remember Biofuels?" [p. 48], reporter Greg Hanscom goes inside the alternative energy industry to see whether biofuels might make a dent in fossil fuel consumption.
