The nutritional value of any particular food includes the number of calories and the amounts of macronutrients (fat, carbohydrates, protein), and micronutrients (vitamins and minerals) per serving of that food. Some nutritional databases also include water, fiber, phytochemicals, along with more detailed information on the different types of fat, carbohydrates and the amino acid profile of the protein.
Calculate the nutritional value of your daily diet (including your calorie count) by using an online database. The United States Department of Agriculture maintains a nutritional value database called the National Nutrient Database for Standard Reference. Diet and weight loss sites such as Calorie Count include programs that will calculate the nutritional value of your diet and also offer tools to track your daily intakes.
You can also get an idea of the nutritional value of packaged foods by reading the Nutrient Facts labels when you shop at your local grocery store. Nutrient Facts labels must include information about calories, fats, carbohydrates, some vitamins and minerals and serving size. If you're not sure what all the words and letters on the label stand for, I can help. Here's a look at abbreviations used in nutrition.
