New warning on excess protein in diet

The lack of references is a major issue for me.

And I thought that whole 'too much protein is bad for the kidneys' idea had been pretty conclusively debunked. Think the only group it IS bad for are those with already compromised kidney function.

I am sure @tim2000s can set us straight! :)

I agree, which is why I posted the aviso. The BBC is apparently running a crusade against high protein diets, there are several related articles, none of which have authors or references identified. I would however propose that those of us leading a mainly sedentary lifestyle shoud not consume more than the RDA (55 gms for men, 45 gms for women) since this will convert to glucose and negate our efforts to reduce bgl. This may be important for anyone on insulin, unless they are bolussing for it.
One BBC report makes the following reference
"The British Dietetic Association (BDA) says high levels of additional protein can cause side-effects, which can include nausea as well as kidney and liver damage"
 
Have you come across The China Study?

I read it a few years ago. Basically the whole book (by two docs) was an interpretation of many, many studies and seemed to link most major illnesses (cancer, etc) to an excess of protein.
It was followed by the usual detractors that follow any popularised book.

I found it absolutely fascinating, and it influenced my eating for a while.

The drawback, of course, is that if you are anywhere on the glucose tolerance spectrum, and you restrict both carbs and protein intake, what else is there? Basically green veg and fats.

So I totally take on board the idea that you can have too much protein. Absolutely. And I think I often eat more protein than I need for my fairly sedentary lifestyle. But at the mo, my blood glucose takes priority, with two portions of protein a day. And all those veg, and fat of course... :D

Given the utte bilge fed to me by some "Registered Dieticians" I would take anything to come from the BDA as requiring careful scrutiny & double checking before given any credibility, IMHO
 
Thanks for the tag guys. Can of worms this one...

There are multiple studies that show protein is bad for bone density and not bad for bone density. That it may or may not drive cancers and that essentially too much of it is both bad and good for you. In addition, there are studies that show higher protein diets can reduce the risk of CVD while there seems to be no link in normal people with higher protein and renal problems, although there may be a case for those with renal dysfunction to eat less.

The answer, as always, is "it depends". I rather like this paper http://home.exetel.com.au/surrealit...ssues of Dietary Protein Intake in Humans.pdf which, although it gets technical, arrives at the conclusion that 25% of energy intake per day from protein is safe and that in reality, more is also probably safe but there aren't many studies to say so either way.
 
I used to eat a LOT of protein but before T1 DX my BG was always high. Then I read The Rosedale Diet and reduced P to an amount I thought I could ever do (45g) and it actually made me feel better. I know as a T2 as well as T1 P raises me as much as carbs. I eat avocado for BF (no P) 2 0z lunch and 3 oz dinner and I am just fine. No muscle loss etc (thanks to insulin). I COULD eat much more because I love it but I find that quantity suitable and some veggies with fat is all I need. I don't think I could do high fat and high P due to digestion. I need to keep meals small so I guess it all balances me and my meals. Not too much of anything (though I still have an 80% fat diet)
 
As an adjunct to my previous post, my experience is that there is a point at which you start to excrete protein in urine if you eat it to excess. My personal threshold on that is about 210g per day, so I eat <200g per day to be sure. That's about 33% of my daily calories, but comes with the caveat that I am weight training 3x per week.
 
Also the LCHF diet isn't a high protein diet, it's a low carb, moderate protein and high fat. 15-20% protein is the norm. Unless, like tim, you have been advised to increase it.

Good point!

The number of times i seen that 'Atkins is a high protein diet' myth reproduced.
No, it isn't.
:)
 
If you read the bbc website, it is peddling, and scuse my French, ****. It talks about excess protein without contextualising it, other than "people generally eat 55% too much" and cross-infecting it with the processed foods are bad and not eating enough veg is also bad. It's really bad journalism and might be worth a complaint as it doesn't effectively put across any valid arguments and is using inference to create a scare story.
