Studies in people

-

How it’s made and used
-
Improving egg component use4
Egg yolk is used less than egg white, so scientists are finding new ways to use it in food.
The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted.
