Hello there,
It seems to be a new trend especially for fighters and other athletes.
Any scientific evidence, support or risks associated ?
Thanks !

Alkaline-type diets are generally fairly healthful with their inclusion of plenty of fruits and vegetables and their exclusion of overly refined and processed foods. However it is important to note that your blood and plasma will not be acidic to begin with since your body will do what it can to maintain a plasma pH of 7.35 - 7.45. Uninary pH can be altered via diet. What the body is doing to maintain pH is what matters. This is where the adherence to certain dietary practices come in to be protective but generally these are not so much issues unless your diet is unbalanced and deficient in things potassium and other minerals or you can't breath.
One study I know of has shown a possible link between the consumption of an alkaline diet and the retention of muscle mass as one ages : [url]http://www.ajcn.org/cgi/content/full/87/3/662[/url]
Some other in vitro studies and artificially induced acidosis have produced impaired protein synthesis, protein breakdown, lower plasma IGF-1 & GH, and higher cortisol. Again, the long-term effects really aren't clear.
But I suspect one main driving reason is not long-term health but how diet may or may not influence pH and subsequent exercise performance and perhaps bone health. The effects appear to be somwhat equivocal relating diet, pH, and exercise performance. Lack of CHO is probably just as important in the end results too. While it may have effects on plasma bicarbonate, ammonia, and pH in the short term study period, are they just transient and could they easily be ameliorated with some vegatables and adequate CHO intake?

You really couldn't have asked for a better first response than that.

Thanks for the links in page 4 of that thread.
Something to ponder.
Supposedly walnuts are very acidic.
Can someone explain to me why this is a problem when cutting or in any diet?
I have walnuts in about 4 meals per day since they are loaded with omega 3's, but wondering the negatives of the acid.
Also, can anything short of cutting back on the walnuts be done to counter any possible negatives of the acid in all the walnuts I am eating?

merged this with the thread 1 row downs titled 'Alkaline Diet'? ;)

sorry about that! Did not catch the gist of this thread.
OK, so, in reading the info above, high acidic foods MAY hurt protein synthesis if your body does not do a good job regulating your blood ph level.
So, for you experts out there:
Should I back off the walnuts?

You should be fine, some walnuts aren't going to tumble you over into a harmful state of acidosis

I think you should be tracking your total food intake.
Not just the benefits or negatives of one food type.

Yeah, excellent point. I kind of figured that out last night.
I started doing some research of alkaline foods vs acidic foods to make sure that my typical diet was not too far on the acidic side.
I think I am good.
This is a very interesting concept, and why I love the advanced nutrition section!
Thanks for all your help everyone!
Its just the urine ph that changes (not the blood ph).
For example, when the body is trying to maintain plasma K+ levels (for homeostasis) certain internal switches may go on that increase H+ or even NH4+ excretion (in the kidney) [b]to help retain K+.[/b]
In fact, transient lowering of plasma K+ (according to textbooks) is a signal for the kidney to start breaking down glutamine (as compensation). However something tells me that any [b]everyday[/b] compensation that is occuring is not really step-wise but rather "seamless" in reality.
Plasma K+ levels of course being important for nerve conduction, etc.
