View Full Version : picky little Protein question

I have read in several Raw Resources that Cooked protein is reduced in half due to reduced digestibilty. My husband..says yeah..bet you can not prove that scientifically and it is just a thing we raw foodies say to further our "cause". So a 20 gram protein cooked only yiels 10 grams when digested, amino acids we are talking about I guess.
So I have been researching and I can find no scientific studies to back this.
Only think I found is:
From Bach Knudsen et al. [1988], protein utilization and digestibility are decreased by cooking in some varieties of sorghum. In contrast, protein digestibility of pearl millet and corn (maize) decreases only very little (not significantly) after cooking [Ejeta et al. 1987].
From Oste [1991], heating (above 100°C, or 212°F) decreases meat protein digestibility. Frying chickpeas, oven-heating winged beans, or roasting cereals at 200-280°C (392-536°F) reduces protein digestibility.
Seidler [1987] studied the effects of heating on the digestibility of the protein in hake, a type of fish. Fish meat heated for 10 minutes at 130°C (266°F), showed a 1.5% decrease in protein digestibility. Similar heating of hake meat in the presence of potato starch, soy oil, and salt caused a 6% decrease in amino acid content.
Anyone who is in the Know on this one ?

I do not understand what outcome you are wishing for here. The average person consumes far more protein than is good for them so it would be a good thing to reduce the levels so that would be an argument in favour of cooking and we do not want to get to that.

The average person consumes far more protein than is good for them I think this is the point to emphasize, not to dwell on what cooking does or does not do to the protein.
Alissa's point on this was very effective for me, that raw vegetables contain more than enough protein for the body's needs, and that typical cooked food diets contain way, way too much protein, causing disease by taxing the body with the constant need to keep eliminating it.

If your husband sees all the great Works going on in YOU, what other proof does he need??

I am not looking for any specific "outcome" other than a resoruce for a statement I have read many times. I am happy with my protein intake as I get plenty from greens so I do not ask for a self serving reason. I do not ask "where do I get my protein from ?" .
I am asking about this because my husbands question to me to as where do I get this info..? what proof do I have that I get more digestable amino acids (protein) from my greens per gram consumed because 1/2 of what he eats (beef) is lost in digestion ?
I can read it here and there but what is the resource for this ?
Seems like I am getting attacked for this question ? If so maybe one of the Mods can close this thread for me.
I am not question being Raw or any of that. I am a 100% Raw foodie.

She wants the resource to prove to her husband that it's true cooking takes away 50%.
She isnt advocating that cooking is ok.
And... I'm certainly not attacking you.
Ppl need to read ALL of an entry & not just a few words to make their decision on what something is about. Not pointing a finger, per say, but I wish more ppl would do this.
I would like to know though WHY you have to prove something to him that is so OBVIOUSLY proven by your experiences. Obviously, you've been right so far! 100% & all the info with it is correct!
L,
PLEASE do not feel bad...I think people misunderstood your point....
FOR ME, my hubby is a person who needs concete fact BEFORE he believes--he is more scientific like. ME, I will believe more on a faith feeling.
Anyways, I think I know what you are asking..IT IS NOT about NOT being raw ~~~it is about trying to prove your point that non-raw eating of meat does not yield one the protein amounts that is toted to. Am I close here?? I see that commercials boost that "4 oz chix yields 26 grams usable protein etc etc."
I think I get your idea...You want ammo to go to him with to lovingly prove your point. That cooked protein AIN"T all it has been cracked up to be.
I am the same way at times with my hubby...Facts work for him where more Faith and people's experiences work more for me.

Hi Rawfigure,
Thank you SO MUCH for your post!
This is EXACTLY the kind of information I am attracted to - the "science" behind the knowledge.
I wish I had more information like this. It feeds my mind, while the raw stuff feeds my body...
Hoping to see more of your posts with information like this on the board!
Here's some information from a book I'm reading:
There is a study by the University of Minnesota showing that women who eat very well done hamburgers have a 50% greater risk of breast cancer than women who eat their burgers rare or medium. (Steinmetz, KA; Potter, JD; Folsom AR. Vegetables, fruit, and cancer in the Iowa Womens Health Study. Cancer Res. 1993 Feb 1; 53(3):536-43
In other words, well done food inflicts massive damage to the genes.
Cooking foods at high temperatures causes the formation of gene-mutating heterocyclic amines and can lead to many types of cancer.
Even if you avoid hamburger, seemingly healthy foods can be carcinogenic by virtue of the way they are cooked: grilled salmon, for example.
This information supplied by Gary Null's book: "Power Aging"
I did read a reference to the cooked food reducing the amount of other nutrition from foods, but darned if I can find it. I'll keep looking. It's not in the Null book, btw.
Again, thanks for the post.

I checked on fitday.com and it tells me that 1 cup cooked beef has 30 grams of protien and 1 cup of raw beef has 40 grams of protien...maybe that will help you with your discussion :D
My hubby is exactly the same!

Excellent post. It helps to ease my residual fears as well as I push further into raw foodism (working toward 100%) and continue to push weights.

I think that it is my remark that is being seen as insensetive here and it was. I knew what you meant by your question and I did not respond correctly. You were looking for specific info and you got a lecture. Please believe that I do not mean to offend but dont anyone expect that this will make me keep my mouth shut. You can not get rid of a bad thing.

rawfigure,
Are your muscle still growing?
or are you having to add addtional protein to your shakes or smoothies?
I completely understand the question. My trainer continualy ask me or jokes with me,( you know it's the kinda jokes that they're saying to you outloud that they are concerned with your lack of protein intake, and your not eating enough food to grow big), your not growning enough muscles your still skinny!
My trainer when he was younger all through school up to his sophmore year was a vegetarian. But when his strength coach introduced him to meats and supplements he blew up,( he's all natural - no steriods). So that's he's proof. Plus I'm sure he has some documentation. But since I've been 100% raw I still get this on a regular bases as well. :rolleyes:

I would love to know the answer to this protein question as well! I have heard that you lose 1/2 the protein in cooking which sounds impressive, but if it is untrue then when it is discounted it will make raw seem less credible. If it isn't true then when answering someone's perfectly valid question about protein I can take a different tack and talk about great sources of plant based protein.
I am going to the person who told me this initially and hopefully hunt down the source of his statement.

Even if I found the staement to be unfounded by Science I would still not eat cooked food or cooked protein...but my husband would say " I told you so". :rolleyes: :rolleyes:
So PATH 301 I do want to answer your question but my work break is over back later.............
