Absolutely.  Corn is stored in elevators and is the same year-round, but grass (and hay) are seasonal.

WalterB:

That's good advice.  (Unless you're trying to take your leucine while otherwise fasted...)

Yes.  I don't know any serious source that recommends less than 1.2g/kg/day for anyone active, and Olympic weightlifters in training can be in negative protein balance at 2g/kg/day!

I've seen the objection that "your body can only build X grams of muscle per day," but that's silly.  Amino acids in the blood aren't just raw materials: some are anabolic signals, particularly leucine.

That being said, chugging 200g+ of whey protein a day is likely to be counterproductive as well as expensive: whey is absorbed so quickly that it's probably not useful to consume more than one scoop at a time.  (Or less: I seem to get the same results from a 15-18g serving as a 30g serving.)  In contrast, it can take many hours to digest and absorb meat, so it's fine to eat a big steak.
