RAND reports on a healthy eating dilemma:
Is eating more fruits and vegetables the key to reducing obesity? A recent RAND study of more than 2,700 adults found that calorie intake from cookies, candy, salty snacks, and soda was approximately twice as high as the recommended daily amount. Consumption of fruits and vegetables, on the other hand, is only 20% shy of recommended guidelines.
Still, eating extra fruit adds more in total calories than it displaces in calories you would have otherwise consumed through junk food. For example, on average, eating one additional serving of fruit reduces about 16 calories from junk food, but it adds 70 calories to your daily total. Therefore, eating less junk food appears more important for reducing obesity than eating more fruit and veggies.
