I remember I used to read that there was no point eating more than about 30g of protein per meal, because the body couldn't use that much in one go and the body couldn't just "store" it to build muscle with it later. So what's the deal? Myth?

Eating over 30g of protein in one meal will make your kidneys explode. I thought you knew this?

I was reading about this the other day, and i cant remember what source it was but it was saying that your body will absorb around 95% of the protein you actually consume.

How much it actually uses im not too sure.

lol, not like that. I'm not worried about kidneys, just if your body can process it and put it to good use? there has to be a limit, specially if the body can't store the protein to use it for building muscle later.

Thats meant to be the most you can digest in a certain ammount of time before its stored as fat, I cant really remember.

yeah, that's what I've heard too. but I think I've heard people say there is no real scientific data to support this. I've never really looked into it, but now a days my protein content per meal gets pretty high so I figured I need to find out.

Numbers are actually around 60-70g from what I've read.

Is there any time limit on these guidelines? I eat very frequently so if I've just eaten 50g of protein when would this have passed through my system enough for me to eat a load more?

well if it is that much it's not a problem. I rarely get more than 70g protein each meal.

Mreik, while you're here. A question about cholesterol:
The body produces about 1g of cholesterol in the liver. If I eat a lot of cholesterol this will go down to compensate, correct? Now what if I eat like 3g of cholesterol a day? the body won't be able to regulate down enough to compensate.. am I missing something? or shouldn't I eat more than like 1-2g of cholesterol a day?

It would make sense that the body would do that wouldn't it? But it's actually not that simple:

"Obesity and dietary plant sterols were negatively associated with fractional absorption of dietary cholesterol in a random population of 63 middle-aged men. Absorbed dietary cholesterol increased linearly with the increase of dietary cholesterol intake. The higher the fractional and absolute absorption of dietary cholesterol the lower the rates of biliary secretion, fecal elimination, and cholesterol synthesis. The findings also revealed that high serum levels of total, LDL, and HDL cholesterol were associated with high cholesterol absorption and that of HDL cholesterol was associated also with low synthesis and fecal elimination of cholesterol. Thus, cholesterol absorption efficiency and absorbed dietary cholesterol significantly regulate cholesterol synthesis and elimination and are important determinants of within-population variation in the serum levels of total, LDL, and HDL cholesterol."

Cholesterol is still very poorly understood. Sure we know a few things it does, and we know an enzyme we can inhibit to lower levels. But even the medicine we use inhibits MANY other molecules such as cell anchoring molecules, which are of dire importance (why statin = myopathy). Anyways, IMO eat your normal diet (normally high in cholesterol) and go to your doctor after several weeks and have your levels tested. This is the only sure fire way to know for sure.
