Blood pH

Human blood must stay near pH 7.365 for normal physiology. Nutritional ketosis preserves normal pH through buffering resources and low ketone levels. Excessive blood alkalinity causes calcium to be deposited in the wrong tissues rather than being properly utilized. Eating a healthy diet is the most reliable long-term correction for excessive blood alkalinity. DKA causes blood pH to fall to lethal levels when extreme ketones and absent insulin overwhelm buffering mechanisms. Starvation can mildly shift blood pH toward acidity because no food is consumed and buffering resources deplete. Misdirected calcium deposits driven by pH imbalance can manifest as kidney stones, arthritis, cataracts, and bone spurs. Tetany — a small, involuntary skin twitch — is a classic symptom of excessive blood alkalinity.
