Question

Diet fads change drastically every few months. In the early 2010s, people were acidifying their diets as a health movement, and after 2015, the push is to alkalinize your blood by eating certain vegetables, and even spending thousands of dollars to specially raise the pH of your drinking water. Why, physiologically, do you know that these fads to alter your body’s pH are a huge waste of money? Explain how the kidney is the main regulator of homeostatic blood pH, and how the respiratory system may help contribute to pH regulation as well.

Lungs maintain blood pH by retention or elimination of carbon dioxide by changing rate and volume of ventilation.
