Our 3 year old daughter is allergic to soy, milk & peanuts. Feeding her is a challenge, but my husband and I are managing.
Are mono & diglycerides soy? I can’t seem to find an answer and was hoping you could help.

A good portion of mono and diglycerides are derived from soybean oil, so I would certainly exercise caution.
What are monoglycerides and diglycerides?
I’ve seen them on food labels but don’t know what they are or why they are in some foods.

Ah, yes. Nothing makes you want to reach for a dictionary more than reading a food label.
Monoglycerides and diglycerides are related to triglycerides (three fatty acid molecules bound to a glycerol molecule) — the basic unit of all dietary fats.
They consist of either one or two fatty acid molecules bound to a glycerol molecule and are mainly used as emulsifiers, thickeners, and binders in a variety of different foods.
Although they can be obtained from triglycerides, they are very easy to create synthetically.
“Non-natural” peanut butters, for instance, contain mono and/or diglycerides in order to prevent the oil from separating from the more paste-like crushed peanuts.
You will also often see them present in margarines and low-fat butter replacements.
While they pose no health risks (or benefits), individuals with soy allergies should exercise caution, since a large percentage of mono and diglycerides are derived from soybean oil.
