Sometimes, the person can eat just some of the ingredients of the system food. For instance, a "hamburger" without "bun" or without "ketchup." And, In this case, the "hamburger" is not a recipe but the regular system food. The user who cannot find the "hamburger without bun" or the "hamburger with no ketchup" item in the suggestion list may want to log a negative "bun" or the negative "ketchup" item in addition to the regular "hamburger."
Instead of logging a negative food to your net diary, we advise creating new custom food based on authentic system item.
On the iPhone app, the user can remove the nutrition facts of some ingredient (ingredients) while Copying & Customizing the system food. The Copy & Customize > Remove Ingredient option is located at the bottom of the food entry screen. For example, it's possible to remove the nutrients of the "table salt" from "hummus" food.
While creating a copy of the original "hummus" item, the user has to give a distinctive new name (e.g., "my custom hummus w/o salt.")
The new item changes the nutrition facts after saving. Each new nutrient is equal to the nutrient of the original food minus the value of the same nutrient in the removed ingredient.
Alternatively, it's possible to remove (or change) the value of the particular nutrient of the Copied & Customized system food. In the "hummus" case, the user can choose the Copy & Customize > Update Nutrients option, change the Sodium value to "0," and tap the Next. Then, make the name of the new copy unique, tap the Save button, and log it to the meal.
The website do not support the Removing Ingredient option while using the "copy & customize" feature.
On the Android app, to Copy & Customize the system food is possible the same way it is on the iOS.
On the website, the Copy & Customize button is located on the top-right corner of the Edit Food Entry webpage.
On the iPhone app, Copying & Customizing the existing system food is possible in another way too. Instead of reducing the nutrition facts while removing the ingredient, the user can Add Ingredient (Ingredients.)
