Ask the doctors: Readers offer feedback on weight loss and extra sunlight

Hello again, dear readers! Once again, you’ve kept our mailboxes brimming, so let’s get right to work.

On the subject of dark chocolate, which continues to tantalize scientists with potential positive effects on the heart, mood and memory, a number of readers wrote to ask whether cocoa powder also offers the same health benefits. Because those powders have been so heavily processed, it’s believed that they may not offer the same benefits as those of regular dark chocolate. As to how much dark chocolate to eat (another very popular question), the current thinking is no more than 1 to 2 ounces per day.

A reader who relies on Tang, the fruit-flavored drink powder, to help him drink enough water every day wonders whether going through 2 pounds of the product each month is OK. On one hand, the powder is fortified with minerals and contains fewer calories than fruit juice. However, the sugar content in Tang is akin to that of a soft drink. We think it would be wise to wean yourself from the habit and switch to water instead. Flavor boosters like a squeeze of lemon or lime, a few slices of cucumber or a quick grate of ginger can help you make the transition.

After reading a column about weight loss strategies, a reader shared her own recent experience. “I’m 83, 5 feet 7 inches and weighed 130 pounds, so I didn’t need to lose a lot of weight, but I wanted my clothes to fit better,” she wrote. “I eliminated alcohol, beef, pasta, potatoes, wheat and sugar from my diet, and continued to eat as much as I wanted of everything else. Snacks were nuts and fruit. The result – I lost 5 pounds in about three weeks and have maintained this weight, even though I now eat whole grain wheat again.”

Thank you all for your kind words, and for your suggestions, criticisms and thoughts. We love hearing from you.
