I agree with others- this isn't a thing to worry about. Way more important to watch overall calorie, protein, vegetable consumption overall.
The only special consideration I give to eating as it pertains to riding is- did I eat enough to feel ok for whatever length of ride I'm doing.

That said, if you can eat protein right after, there seems to be some benefit, so why not? But if you don't get it in, it's nothing to worry about.
