Nutrition for Prepackaged items

For example you purchase pre-made  sandwiches. That sandwich has a label with nutrition information. You will need to enter the nutritional information in reciProfity's Custom Nutrition section (click the Main Menu/ Optimizer/ Custom Nutrition) 

BUT you will need to enter it with the 100 gram nutritionals as a custom item in the nutritional datababase.

How do you do this? 

The USDA  FoodData Central database contains the nutritional information for  the USDA Global Branded Food Products Database (Branded Foods).

Nutritional info in this database is already in 100 gram portions. Copy those nutrient amounts into the reciProfity Custom Nutrition fields.

If your ingredient is NOT in this database you can get the nutrients from the package label. Just remember that the USDA uses 100 gram portions for calculating nutritional information so you will need to insure that the info you put into Custom Nutrition is per 100 gram serving portions.

1. Find the weight of the item

2. Calculate the nutritionals at 100 grams.

If the sandwich weighs 200 grams, you would enter ½ of the nutritional amounts, ie 100 grams, into the database. Then reciProfity will calculate the full sandwich nutritionals once you create a sandwich recipe linking to that single item.
