Enter or edit nutrient values for a food

To specify the nutrient composition for a custom food, you can:

• Enter the nutrient values for the food from an external source.
• Base the nutrient analysis for the food on another item (by choosing a similar item from the data sources or from your own custom foods and recipes in the workspace).
• Set the nutrient values to zero or unknown.

You can also use a hybrid approach where you base the analysis for the food on another item, or set the values to zero or unknown, but also enter some nutrient values from another source.

To enter nutrient values for a food from an external source

1. Open the food.
2. On the Nutrients tab, in the Value column, enter the values for each nutrient per 100g (or,  optionally, enter another weight in the Value field for Weight (g)). 
3. Optional: Make notes about a nutrient in the Note column.
4. Click Save.

To base the analysis for a food on another item

1. Open the food.
2. On the Nutrients tab, in the Base analysis on dropdown list, select Other item.

4. Optional: For any nutrient for which you prefer to use data from another source, type the preferred value in the Value column.
5. Optional: Make notes about a nutrient in the Note column.
6. Click Save.
