mammals drink the milk from our own species. we are the only species that drinks milk from other animals. and notice a quote i provided earlier that shows that a large amount of people are lactose intolerant. some races of homo sapiens are as much as 75+% intolerant.
in case you do not know that that means, Lactose intolerance is the inability to digest lactose. Lactose is a type of sugar found in milk and other dairy products.
from this link:
http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001321/
yes, that means that most homo sapiens cannot even digest the carbs that are in milk. notice how that link also states that babies body’s naturally produce the enzymes needed to metabolisse lactose. as adults we do not produce enough or any at all. that does not sound like something that is meant for us.

quality? you may not have seen that link i already provided that showed that human milk has less protein then cows milk. and i would think that human milk is what is meant for us to drink more so then another animals milk.

correct. so whats my point? or for that matter, your point?

The “key” to building muscle is not just calories. Your assumption is wrong. Muscle is made (mostly) of contractile proteins. If you do not have protein, you cannot build muscle. At all. It’s impossible. Sure, you may not need 300+ grams a day, but you do need a large amount.[/quote]

not just calories? lets look at this a few ways.
say we want to build muscle with protein intake. we can safely say that we can put on 10lbs of muscle in a year. that is 4,546 grams of muscle. which breaks down to 12.5gr/day of protein needed to have the building blocks for that muscle. as i have shown with science from earlier posts that i, at 190lbs, need 150gr a day and i add in 12grams for the building blocks i need 162gr/day. still far less then what bodybuilders say is required and even less then what the OP stated as a minimum to maintain muscle. the math does not add up at all.
and i agree that without enough protein you will not grow muscle. and you say you do not need 300gr/day but a large amount. can you provide evidence of what is needed? i have and it shows less then 1gr/lbs per day. which matches my statements of 150-162gr/day of protein as a good enough source to grow more muscle.

for those that like bodybuilding as a source of knowledge, i offer this link:
it states that nitrogen balance is an accurate way of measuring ones anabolic state. when you have positive nitrogen balance you can grow muscle. an early link i provided showed that a diet of 12-15% of total calories from protein or less then 1gr/day per pound of bodyweight was sufficient to produce a positive nitrogen balance.
it even goes on to state that total caloric intake is important. if you do not have enough total calories and protein is the main source of fuel it will use that and can lower nitrogen balance. this further backs up my statements.
6-
to further talk about nitrogen balance:
http://www.ajcn.org/content/2/6/405.short
that shows that protein is most important for nitrogen balance but a finding of 500 calories with 7-8% from protein is enough to maintain nitrogen balance.
so if 300gr/day of protein is needed to gain muscle that means that over 17,000 calories are needed for optimal muscle growth. you have also made the statement that other do it so it must be correct. lets ask those people if they eat 17k+ calories a day or if they can gain muscle on fewer calories. i am guessing that those people are gaining with 1/3 of that total caloric intake.

Certain ethnicities have a higher incidence of lactose intolerance because they did not traditionally have cows in that part of the world. So these people had no more use for the lactase enzyme, so it evolved its way out.
I know what lactose is. I described it in the post you are replying to.
No, that means for some ethnicities that did not traditionally have cows, the majority can not digest lactose.
Babies bodies naturally produce lactase (the enzyme) because we are mammals. If they never drink consume dairy after infancy, there is no need for the enzyme, and the body will stop producing it.

Yes, I know that human milk has a lower protein content than cow milk. Cow milk is still a quality protein source. The vast majority of people tout whey protein as being a quality protein source, and it is derived from cow milk.

Your point was that you don’t need very much protein to build muscle. You used vegan bodybuilders as an example because “they are probably bigger than me and you, and they eat much less protein” or something to that effect. When in fact, you have no idea how much protein they consume. So this example is useless.
4-
I’m not sure if you know this, but the body uses protein for a lot of other things than building muscle.
I did not say you don’t need 300 grams a day. I said you may not need that amount. Nobody can tell you how much protein you need per day to gain or maintain muscle.
I also don’t care what the studies you posted say, because as the OP pointed out, they are shitty studies. There is not much scientific research in building muscle, as it is a VERY low priority in the scientific community. Most of the small amount of studies that have been done are of poor quality.

A positive nitrogen balance does indeed mean that your body is an anabolic state, like you said. When your body is in positive nitrogen balance, you CAN build muscle. This in no way means that you ARE building muscle. If I drink a soda on an empty stomach, my body will be in anabolic state in a few minutes, because insulin will be released, causing glucose to be absorbed into the cells as well as being stored as glucagon. This is an anabolic process. Anabolic means that larger molecules are being synthesized from smaller ones. No muscle is being built in this soda example.
A positive nitrogen balance simply means that as a whole, the body is in an anabolic state. It does NOT mean that the body is currently increasing muscle mass. Thus, the amount of protein required to put the body into a positive nitrogen balance means nothing. The goal is not simply a positive nitrogen balance, but building muscle.
Again, most of the scientific studies on this subject are shitty.

I never said 300 grams a day was neccessary. To insuate that 17,000 calories a day is neccessary is asinine.
I never made the statement “that other do it so it must be correct”
Ask them, I’m not the one who said 17,000 calories a day was neccessary.
