Bioavailability

Can some please expalin to me in dumb arse terms what this actually means.

Why is the protien that is locked in say two boild eggs (12%) better then a cooked can of baked beans (12%)

Or 2 cooked eggs opposed to 2 raw eggs??

(and no, Im not eating raw eggs again :shifty: )

true, i didnt know there was that much protein in beans :o .

whole eggs are a great source of protein as they also contain the best matching aminoacids to what the body needs. as you know cooking them helps increase the BA of the egg

Im googling about, but do you guys know if theres a chart somewhere that show what proteins in what foods are more bioavalable then others?

I found this site this morning.

As you may have guessed I have run out of protien shake, but i am still intrested and this stuff is quit handy too know.

The only thing Ive got till thursday is 400grams of prime mince beef, 3 boild eggs and 1 tin of baked beans.....LOL

Such is life I spose :roll:

I know eggs are good, but I thought whey had the best bioavailability? (The only people I've heard say eggs are better sell egg whites, so I've always been a little sceptical of that claim)

yea egg white is what they judge other proteins off, and whey is better in terms of bioavalibility. I must have made my post look confusing

best bioavalibility = whey

best biological value = whole egg

lol, mikey6 aka mike-311 i was wondering wat the black crow means in yr avatar?

Its a Raven, and it usually sits in the middle of my bussiness card. "Raven Protection"

No thats not all the food I have till thursday, but its the only protein rich food I have untill thursday (apart from some snags and lamb patties) and it sucks. So Ive got to make the most of it.

But its ok Ive scored a 30 tray of eggs, now what to do about tomorrow??...LOL

Im Not poor but my crediters are :x

u have your own bussiness?

well mikey6 aka mike-311 u could always nick a protein powder from a shop where u are working as security..... ud be the last theyd suspect... ud have to think of a way to conceal it though...

thanks mike-311 aka mikey6 but im ok.

i was just trying to help with a suggestion that u might have found helpful. or even better u could get one of yr mates to shop lift and u 'chase him' then come back to the shop and say to the shop keeper u lost him or he was too fast. then u got yrself a protein that way. that way u wouldnt technically be stealing, just plotting.

wat u think?

best bioavalibility = whey

best biological value = whole egg

You're getting your BV's crossed - BV means biological value which essentially is a measure of protein quality and the effect it has on supporting nitrogen retention in the body. Egg protein was coined the gold standard back in the 60's due to having a very good amino acid profile - then along came whey in the 80's/90's which blew it out of the water. Egg's are good but not as good as whey as far as BV goes:

Biological Values of Common Proteins

Protein Source BV

Whey Peptide Blends (Isolates/Hydrolysed Whey) 110-159

Whey Protein Concentrate 104

Whole Egg 100 i.e gold standard so they rated it 100

Cow’s Milk 91

Egg white (albumin) 88

Fish 83

Beef 80

Chicken 79

Casein 77

Soy 74

Rice 59

Wheat 54

Beans 49

It's not just the BV that makes whey protein good though - as mentioned the biological value provided by the growth factors and microfractions found in whey protein have huge benefits for your immune system that no other protein provides.

Pseudo - yes it appears the only people saying egg white is best are the people who make it. Make of that what you will.

There's benefits to all protein - different amino's, different absorption rates etc so your best bet is to aim for a combination. If you can get at least 50% of your protein from WPC and/or undenatured WPI's, and the rest from quality meats, dairy and eggs then you will probably get better results as far as muscle growth and recovery than someone that gets all there's from just eggs or meat.

And as far as getting protein from baked beans (man this is deja vu, I've been over this before for someone) they have a BV of 49, and you get at most 4.5g of protein per 100g. Compared to WPC at BV 104, with 77g protein per 100g, you pretty much have to eat 3.4kg of baked beans to get the same amount of usable protein that 100g of whey provides. I know which one I'd choose.

Ah. Cheers, Flex. I was talking about this with my training partner last night, but was a little fuzzy on the Why's.

3.4kg of baked beans would certainly produce an interesting result. In the interests of Science, someone should film it, and put the video on YouTube. (On second thoughts, they probably already have.) :D

thanks for that flex, so is whey no1 in terms of Biological Value as well as Bioavailability?

So have I got this right?

Bioavailability - how easily a protein is absorbed by your body

Biological value - how useful a protein is for your body

So theoretically you could have an easily-absorbed protein that does bugger-all, and vice versa.

Is that right, or am I completely confused? :P

Bioavailability applies to everything - vitamins, minerals, protein, creatine etc and relates to how easily absorbed it is by the body, BV Biological Value only applies to protein. The bioavailability is kind of measured by the BV Biological value of a protein - generally the lower the bioavailability of a protein the lower the biological value as it will have less impact on nitrogen levels. However a protein can have a high bioavailability and be absorbed easily but if it has a weak amino acid profile it will score a low BV. I think that some confusion has been caused with people misquoting bioavailability as BV.

I kind of made made my other post a little confusing when I said:

It's not just the BV that makes whey protein good though - as mentioned the biological value provided by the growth factors and microfractions found in whey protein have huge benefits for your immune system that no other protein provides.
so I'll rephrase it

"It's not just the BV that makes whey protein good though - the benefits provided by the growth factors and microfractions found in whey protein have huge benefits for your immune system that no other protein provides."

Because the BV was developed to relate to egg protein (egg at 100) the BV measurement is pretty confusing and, depending on what you read, there seems to be some confusion over what the measurements actually mean. There has been attempts to come up with new ways to measure protein quality - the PDCAA's - Protein digestabilty corrected amino acid score which takes into account of how well a protein is digested and how well it supplies the amino acid needs of an adult. This has some flaws though, and there is another score the PER - Protein efficiency ratio, however this doesn't seem to have really taken off when it comes to the sports nutrition industry.
