Dear Sir, Physical exercise produces lactic acid and oxalate. Lactic acid shares similarity to oxalate in structure, and inhibits the generation of oxalate. The build-up of insoluble and rigid oxalate salts such as calcium oxalate via energy metabolism is stressful to the cells. Acetic acid and ethanol share structural similarity to oxalate, reduce the risks of cardiovascular diseases and extend lifespan, perhaps by inhibiting the generation of oxalate. The ratio of lactic acid to oxalate is critical for heart health during exercise, and excess lactic acid helps dissolve rigid oxalate salts. Moderate exercise is beneficial to the cardiovascular system, and increased blood circulation during exercise allows anion traffic, helping dissolve insoluble salts. However, exercise should proceed with caution when symptoms of discomfort start to appear. Furthermore, weak organic acids produced from energy metabolism counteract the carcinogenic effects of strong acids such as hydrochloric acid. Physical exercise also diverts protons to the limbs for energy production and reduces stress in internal organs.
