"A new U.S. study adds to growing evidence that nuts - once considered too fattening to be healthy - may in fact help keep weight down, in addition to offering other health benefits.
Researchers found that study participants who ate the most tree nuts...were between 37 and 46 percent less likely to be obese than those who ate the fewest tree nuts.
Overall, those who ate a lot of tree nuts - about 16 grams (half an ounce) per day - were just a little over normal weight, on average, compared to those who ate few or no nuts and were seriously overweight or obese."
The resident cynic says that even more benefit would accrue if people grew and harvested their own tree nuts. The greatest benefit would be seen in the less mentally gifted. Climbing trees is great exercise.
