What Is Normal Acidity For a Human Being?

Your body has a very small buffer zone to maintain normal acid-base balance in your blood. According to dietitian Mary Grosvenor, normal pH level in your blood must be between 7.35 to 7.45. Any level outside the normal range can be fatal.

  1. Definition

    • Acidosis is a condition when your blood has a pH level less than 7.35 and alkalosis is having a blood ph level greater than 7.45. To maintain normal pH balance, your body produces buffering agents, such as ammonia and bicarbonates, that keep your blood pH level within range.

    Symptoms

    • Symptoms of acidosis include severe headaches, diarrhea, vomiting, seizures and increased heart rate. Its counterpart, alkalosis, causes muscle weakness and cramps, elevated blood calcium levels and tetany. If left untreated, either condition can cause coma and death.

    Prevention

    • Physiologist Stuart Fox recommends you eat a variety of foods accompanied by plenty of water to maintain healthy blood pH levels . Avoid eating too much food that can change your pH level greatly, such as meats, coffee, eggs and fermented foods.
