Protein Effeciency Ratio

RONJON · Jan 27, 2009

There was a book sale at the library yesterday and I picked up an old VHS by Joe Weider from the early nineties. On the tape there is alot of talk about the "Protein Effeciency Ratio." According to the tape fish and eggs are more complete protein and absorbed better than ground beef and pork, chicken and turkey followed by protein from milk.

They advocate switching up your protein sources..but if fish is the best absorbed than why wouldn't it be better to use fish as the majority of your protein?

And as far as Protein in supplements..how much is actually "absorbed?"

I thought that maybe the perspective on this might be different nowadays...

ya its really intersting to see things like that because over the past 20 years the understanding of diet and how the body works has changed so much.
shit in china they still think that drinking cold water will make u fat. lOL

I have taken alot of culture based dietetics courses and its really intersting to see how far behind some countries are in the world of science and nutrition.

but as far as what that vhs showed it is somewhat politically correct. but the protein powder has changed so much over the years I think that may be overlooked a bit.

but if you look at it in terms of there BV values its pretty spot on (except for whey and milk).The BV or biological value of protein shows how much the body absorbs and utilizes of that protein. The higher the value the more completely the protein will be absorbed and used by the human body

whey and eggs are the highest at around a 100
milk is next with 85-90
fish 75-85
casein around 80
beef-75-80
chicken up to 79
soy 74
wheat- 69
legumes 50-60
all these can very based on alot of variables type of cut, type of fish etc etc etc.

I think the best option is to look at the list and use most of these in modertion. If you are using the top 5 consistantly and religiously you are making your requirments. other things to considers is what you are taking in while you eat these protein, fats, fiber etc alot of things may interupt with the body absorbgin it faster or slower or more efficently.

As per Lyle McDonald:

Protein Efficiency Ratio (PER): PER is a measure of the amount of weight gain (in grams) in rats compared to their protein intake. It’s always measured in young growing rats and, frankly, has about zero relevance to human physiology.

That's pretty much my opinion on the PER
