Milk guzzling

Sen said:I didn't say you were Ox, it was just an amusing note to end on, I meant no offense by it



(I FEEL) Saturated fats are not as bad as popular media would have you believe, I don't take sat-fats to be a negative anymore! BUUUT this topic can be very volatile as people hold VERY VERY different views on it.
-I agree totally on the Lactose views though! Milk is a great carb-source, IF you can tolerate them!


If you are the article reading type, this is a very interesting read regarding various saturated fats;

I won't push my views on anyone but I think it is a genuinely nice read, for those that like to read and have an opinion either way!
I wont say more on that topic, its like discussing politics with close friends! just don't do it! lol

The nitrogenous part will be lost in urine, so people who buy endless supplies of whey protein and over-consume above their demand are, literally pissing their money away. Knowing your demand however is quite a skill I'd imagine and would take trial and error

That's not enirely true though is it - we can store aminos. Also an increase in protein intake causes an upregulation of protein useage within the body IIRC. So all is not always wasted.

MattD90 said:
We cannot store amino acids! Excess beyond demand will always be deaminated and then either respired (C-skeleton) via TCA cycle intermediates, or stored as fat, with the excess nitrogen lost as urea.
Of course technically we can "store" amino acids as proteins, but I mean excess beyond our capable level of protein synthesis will always be broken down as above. There is no storage system for excess amino acids (!)

Doesn't the body 'hold' some amino acids within the system ( referred to as the 'amino acid pool' ?) for a period of time to allow for the combining of them from 'incomplete' protein sources?

MattD90 said:
Of course amino acids are constantly present in the blood after absorption from the intestines. But I wouldn't think of this as a "storage" because while it is technically an 'amino acid pool', it is not one we can add to over time by consuming excess amino acids (ie in dietary protein), unlike fat stores (and to some extent glycogen) which can. The amino acid content of the blood is finite and in cases of over-consumption of protein whereby input by far exceeds "need", ie rate of protein synthesis, energy status and so on, amino acids will ultimately be converted into other things.
