If you drink egg whites there are some things to consider.
There is a risk of salmonella with raw eggs. One can get pasturized liquid egg whites at the store and that mostly eliminates that problem. I did start drinking one container that had gone bad. Smell the eggs to double check that they are ok.
Raw egg whites have a protein called avidin. Avidin binds with biotin and if you drink raw egg whites you can get “egg white injury”. It is a problem of not enough biotin. There is a lot of biotin in the egg yolk. I suplement with a 1,000 mcg biotin pill if I drink any pasturized liquid egg white.
Pasturized eggs still have all the avidin in them. Cooking the egg whites denatures most but not all of the avidin.
Depending on what you consume, 35% of the liquid egg white is not digested for healthy people. If you add fat it slows the digestion process so more is digested.
One will have foul gas with drinking straight liquid egg whites. This is because it is not all digested. I do not have any problem when I drank straight liquid whole eggs.
One of the proteins in the egg white makes the “foam” when beaten. So do not pour liquid egg whites into a blender unless you really want foam. I found it best to: 1) mix my protein drink in the blender, 2) turn the blender off, 3) pour liquid egg whites into the blender and then 4) stir gently with a spoon.
