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? 

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.
