After a longer workout (over one hour), a combination of carbohydrates and protein in a 4:1 ratio is recommended for recovery.
I have to admit I thought this was going to be a stupid article with worthless advice. But I have to admit that Dr. Melina Jampolis did a great job responding to this question.
Without knowing the details of the child, she listed some valid options of when to take a protein drink -vs- a recovery drink. Good advice for all of us.
But I was surprised that she didn’t dwell on the actual nutrition lifestyle. Maybe suggest that getting the protein from whole food sources verse the standard process foods would be a better start. But she is the one with the MD in her name.
