How do you give a food more than one unit of measurement to choose from?

When I pick a food that's already listed a lot of times there's oz, g, different sizes, etc. When I add a food I end up with just one to choose from. Sometimes the amount I eat is a lot smaller than the serving size. How do I add more measurements?

I don't think you can-- those all seem to come from the USDA food database.

Adjust the serving size using decimal points - for example, if you eat two-thirds of a cup of yogurt, change the serving to .66.

It won't let me use decimals on my iPad but it let me on my phone. Thanks for the tip

Any ideas when decimals will be available on iphone/ipad app?

When I adjust my serving size using my iPad, the decimal I enter is automatically converted to an equivalent fraction. You may be in need of an update for your iPad or you could simply enter the amount in fraction form instead.

on a computer when you pull up the full nutritional info for a food underneath the info is a section that says who added that food to the database. There it asks "is the information inaccurate or incomplete? click here to edit"

At the top of that page there is another like where you can select to add a different serving size of the food. Some stuff, like candy, coming in bitsize, funsize, kingsize etc. It helps to have all the portion info under one.
