Include weight of food in Export Entries

It would be really nice if the "Export Food & Recipe Entries" feature included the weight of each food. It does currently have an "Amount" column, but if I logged it by volume or another serving name, such as "2 cups" or "1 bar", then it doesn't show how many grams it is.

I'm planning to try to test correlation between amounts of foods I eat to metrics in my life like hours of sleep, but currently I can't do that easily since there is no "grams of food" column.
