Fear Acidic Exercise NOT Acidic Food

Many mistakenly blame food for shifting the body into an acidic state. Saying that cancer grows in an acidic environment (low pH), and hypothesizing that the consumption of highly acidic foods (like meat and cheese) promote cancer growth.

Even though most experiments show cancer growth at normal pH (7.4), and our body has a natural buffering system to handle highly acidic food.  Plus, any research supporting a correlation between cancer and pH focuses on increased acidity in blood and other fluids, and food is only capable of altering the acid or alkaline levels in our urine.

Interestingly, the same can’t be said for exercise.  Other than excessive free radical and cortisol accumulation, lactic acid is an unfortunate byproduct of exercise that elevates oxygen and acidity inside (and outside) muscle cells, and lowers pH.

“Although acids and bases are present in foods, the major threat to bodily fluid pH is acids formed in metabolic processes.”

Normally, the kidneys would regulate pH by excreting more or less bicarbonate, but this is an ineffective regulator during exercise. Resulting in extra stress on our cells, and producing pH disturbances that can lead to something more serious – like rhythmic disturbances of the heart.

Since the amount of lactate produced is based on exercise intensity and duration, and accumulation depends on a balance between production by the working muscles and removal by the liver and other tissues, continuous (aerobic) can pose a significant risk.

Running for a few minutes, drops our normal pH of 7.4 to 7.0, and continuing or repeating the same activity can lower it to 6.8 – which is considered the lowest tolerable survival pH.

Suggesting that if you’re worried about acidosis, that 2hr run you had yesterday morning should be a much bigger concern than any acidic meal.
