diveoceanos,
Having done experiments with apnea diet since 1999, I can make some statements based on personal experiments as well as confirmation from many other freedivers.
Modifying diet does little or nothing to change your blood pH, but it can change the amount of buffers in your blood.
The simplest experiment that anyone can do, is to:
1. Try doing a breath-hold and measure the time of the first contraction
2. Mix 15g of baking soda (NaHCO3) into water and drink
3. Wait 45 minutes
4. Try another breath-hold and measure the time of the first contraction
The contraction will be dramatically delayed. You can then do a control experiment:
1. Try doing a breath-hold and measure the time of the first contraction
2. Drink water
3. Wait 45 minutes
4. Try another breath-hold and measure the time of the first contraction
Compare the results. It will be extremely obvious. This is not a method designed just for freediving -- sprinters and middle distance runners have been doing it for years.
