If you believe the bestseller lists, the biggest bad in the supermarket aisles is not fat or sodium or sugar but wheat. Its not just the booming popularity of gluten-free products, which are important for the small percentage of people diagnosed with celiac disease but whose benefits for the general population are questionable. (For a full discussion of the pros and cons of gluten-free products, see our October 2013 Special Report.) Bestselling books have warned that wheat consumption is a key contributor to abdominal fat (wheat belly), as well as triggering diseases ranging from diabetes to autism, and that eating wheat is linked to Alzheimers, depression, headaches, epilepsy and ADHD.

By their own report, Americans ate less healthfully last year than any time since 2008. A daily poll by Gallup and Healthways, totaling more than 150,000 adults over a years polling, asks whether respondents ate healthfully the previous day.

"The profile of cranberries' biologically active constituents is distinct from that of other berry fruit," says Jeffrey B. Blumberg, PhD, director of Tufts' HNRCA Antioxidants Research Laboratory. Blumberg and colleagues recently authored a comprehensive review of cranberries' bioactive compounds and their effects on human health, published in Advances in Nutrition.

Dating back millennia, fermented foods are among humanity's oldest attempts to preserve food. But today these foods are newly popular for their purported health benefits. Fermented foods, ranging from sauerkraut to yogurt, are increasingly being seen as a boon to the gut - and in turn to benefits not only for digestive health but possibly also for allergies and even weight loss.

A. Bess Dawson-Hughes, MD, director of Tufts HNRCA Bone Metabolism Laboratory, answers: The amount of calcium present is very small and so not very consequential. The other ingredients have negligible nutritional value, are commonly used, and I know of no evidence that they are unsafe.…

Per tablespoon, granulated (table) sugar has no vitamins or minerals, and honey has slightly higher, but still negligible amounts, while the same amount of maple syrup actually has about 15% of the Daily Value (DV) for riboflavin and 30% of the DV for manganese. Honey and maple syrup also contain several different…
