# Calculating Calories and Nutrients in Meals | Jean Mayer USDA Human Nutrition Research Center on Aging

## 1). Calculating Calories and Nutrients in Single Ingredient Meals

The calorie and nutrient contented of one ingredients and person foods can normally be found in the USDA ’ s National Nutrient Database. In accession, most packaged foods list data in the Nutrition Facts dialog box. Follow the steps below to find nutriment information for a one food or ingredient :
1. Go to the USDA National Nutrient Database.
2. search and select food token of interest. sometimes there are multiple options ( e.g. chicken breast with and without bark ; roasted, fried, etc. ) thus choose the choice that is the best match for the food you are using.
3. Input the amount of food and click “ put on changes. ” note that there are gram values for all provide unit measures, which is the lapp whole used on the Nutrition Facts label .
For example, if you want to know the calorie subject of 2 cups of a food item, adjust the numeral prize in the column titled “ cup ” to 2 .
other unit conversions may sometimes be necessity if the unit of interest is not an available option. For exemplar, if you want to know the calorie content of 8 oz of a food item but entirely the prize for 100 grams is available, then you will need to adjust the numeric prize in the column titled ‘ value per 100 grams ’ to 2.27 .
1 oz = 28.4 grams
8 oz = 227 grams ( 8 adam 28.4 grams )
227 grams/100 grams = 2.27 ( so you would need 2.27 times the 100 gram rate )

1. A useful conversion tool
2. Calorie information is the second row and is titled “Energy.” Other nutrients commonly reported are in the rows immediately following: protein, total fat, carbohydrate and total dietary fiber. Sodium is in the section titled “Minerals” and saturated fat, unsaturated fat and cholesterol are located in the section titled “Lipids.”

Calories, nutrients and weights displayed for each food are for the edible part of food ( for exemplar – without bones, etc. )

## 2). Calculating Calories for Recipes and Mixed Dishes

A lot of the foods we eat have more than one ingredient. For exercise, a chicken breast is rarely prepare plain and may include some type of fat used during cook, a sauce add subsequently, or early ingredients. Multi-ingredient recipes can be calculated by entering data for each individual ingredient into an MS Excel® spreadsheet that has been set up for this aim. The spreadsheet gives you the option to list how many servings the recipe makes and will calculate the calories and nutrients per serving. Follow the steps below to calculate the nutrition information for a multi-ingredient food or recipe .

1. Type the names and amounts of each ingredient into the spreadsheet.
2. Go to the USDA National Nutrient Database. Determine calories and nutrients for each individual ingredient in the correct quantity as described above.
3. Enter the data into the spreadsheet and it will add up values for the total recipe. When you enter the number of servings, the spreadsheet will determine calories and nutrients per serving.

## 3). Calculating Calories for Full Meals

typically a meal consists of several different foods, some of which may be recipes that contain multiple ingredients. An case would be a stir fry ( recipe with multiple ingredients ) with a side of rice ( single ingredient ). Calorie and alimentary values for meals can be calculated by entering the values for the individual ingredients and for the single serving assign of recipes into a downloadable MS Excel® spreadsheet that is set up for this purpose. Follow the steps below to calculate the nutrition information for a meal .

1. Type the names of the ingredients and the recipes, along with the amounts of each into the spreadsheet. Alternately, recipes may be copied over from the Recipe Calculator above.
2. Go to the USDA National Nutrient Database and look up the calories and nutrients for each individual ingredient in the correct amount.
3. Enter the information into the Meal Calculator spreadsheet including number of servings for each individual ingredient or recipe. The spreadsheet will then sum calories and nutrients giving you values for a single serving of the entire meal.

## Notes

The USDA database does contain some quick calculate meals, however, we recommend you calculate the alimentary information for your dishes as described above, in ordain to obtain the most accurate composition for your own recipes .
The more precise you can be with the exact food, amount, and servings per recipe, the more accurate the calories and food values will be. besides, be aware of often forget ingredients such as vegetable oil, butter, or broth used in cook .
The methods described above assume that all of the fat used in cook is consumed. For deep fry items, however, select the appropriate choice directly from the USDA database .
