I have always had a liver that produces very little protein. As long as I can remember I've had to consume egg whites for that specific type of protein. It is a protein that the body utilizes better than most. Use to get the gallon size jar of egg white protein shake from the health food store back in the day. Not popular anymore because people focus on highest protein per serving instead of kind of protein. When I've raised chickens, ducks and turkeys I've taken the extra eggs (whites) and dehydrated raw and boiled. Great space saver. Gallon of whites yeilds about 2 cups of powder. Boiled whites around double that. Keep in tightly sealed jar away from light. They say it keeps for 2 years. I personally am still using jars I've had stored for 5 years. Powdered raw can be added to recipes where eggs are used. Whole egg to eggwhite conversion can be found online. Can also add oil to rehydrate for scrambled egg whites. Powdered boiled is what I use to make almond milk protein milkshake but use your imagination for other uses.
