"Millions of people are calorie-conscious. They measure the number of estimated calories contained in their meals primarily because they wish to lose weight or avoid gaining it. But many of these people miss the big picture, the fact that regular exercise is as important as caloric discipline. This book explains the ins and outs of calories for young children. It describes the sources of calories, daily calorie needs, the meaning of 'empty' calories, and the problems that can result if someone eats too many of them. Your readers will understand the need to balance caloric intake with exercise"--Provided by the publisher.

This volume explains for young children both the positive and negative aspects of fat-containing foods. It differentiates the types of fats people consume, notes the links between fats and calories and fats and cholesterol, and addresses such issues as the dangers of dieting by fasting"--Provided by the publisher.

"Carbohydrates are the body's primary energy providers. Written for young children, this book discusses the main forms of carbs, how they are created, and why they are important.

It details how carbs are broken down in the digestive system into units small enough to be distributed through the bloodstream, absorbed by cells, and converted into energy.
