The pH of different cellular compartments, body fluids, and organs is usually tightly regulated in a process called acid-base homeostasis.
The pH of blood is usually slightly basic with a value of pH 7.4. This value is often referred to as physiological pH in biology and medicine. Plaque can create a local acidic environment that can result in tooth decay by demineralisation.Enzymes and other proteins have an optimum pH range and can become inactivated or denatured outside this range. The most common disorder in acid-base homeostasis is acidosis, which means an acid overload in the body, generally defined by pH falling below 7.35.
Most of us never considered the pH level of our body or even that our body has a pH level. pH level is about the balance of acid and alkaline in the body. Disrupt that balance in both direction and health problems will result. The only truly acidic environment in the body is the digestive system where acid is required to break down food. The human body is constantly adjusting its PH level in order to keep balanced but in these days our diet consists predominantly of acid forming food. In this situation the body will try to neutralize the acid excess by using minerals such as calcium or magnesium. Calcium gets leeched from bone tissue to buffer acidity and magnesium is taken from cells and the cardiovascular system. The body will always seek to balance acidity and alkalinity at the expense of its own long term health. By eating a diet of 40% fruits and vegetables (all green foods are alkalizing) and the remaining percent meats, fats, whole grains, you can keep your pH level within normal. The result of too much acid in the body will kill friendly bacteria and the immune system becomes weakened as result of changes to the wall of the small intestine which impair its ability to absorb nutrients. The body needs more alkalizing food than acidifying foods. Also too much acid decreases the physical performance which limits muscle contraction and expansion during exercise For those who see the importance of pH balancing, Nature's Sunshine Green Zone and Chlorophyll offer powerful alkalizing potential in maintaining pH balance. Nature's Sunshine products have demonstrated a commitment to using only the finest raw materials available.
