Here's a little book with a big supply of all the important numbers. They're taken from the most reliable source available, the U.S. Department of Agriculture's Nutrient Database for Standard Reference. Information is clearly arranged in table form, with designated serving sizes for each food allowed by:Total calories; calories from fat; protein (grams); carbohydrates (grams); sodium (milligrams); cholesterol (milligrams); fiber (grams), etc. Small in size but packed with information, this book is a reliable guide to eating well while enhancing health.
