Nourishing Your Body, Renewing Your Life
Welcome to Your Renewable Life
The pH (power of Hydrogen), which is commonly remembered from high school as acid or base (alkaline), is tightly controlled in the body.
In our digestive tract, particularly the stomach, the pH is very low (acidic). This is to break down food, activate enzymes, and increase the absorption of nutrients. The rest of our body, however, prefers a more alkaline environment. Since our system, the human body receives nourishment through the blood, this pH is tightly controlled between 7.35-7.45, slightly alkaline.
When the blood falls below this range and becomes too acidic for our system, our bones break down and release calcium to restore balance. On the other side of the coin, if our blood pH raises above 7.45 then the alkaline substance in the blood, calcium, is sent to our bones for storage and building of bone. This process keeps what is called Calcium Homeostasis in the body.
Calcium is used in several of our body processes, but our bones get first dibs. As you can imagine, it isn’t quite as simplistic as I explained in the previous paragraph. There are several other important co-factors that keep the harmony of proper calcium nourishment throughout. That said, most of us aren’t deficient in calcium, but many of us are missing one or more of the co-factors needed to achieve this calcium homeostasis optimally.
This post will be too long to go in-depth on all of these co-factors, but I do want to mention the role parathyroid hormone plays. Parathyroid hormone regulates the actions that our bones take in the building and breaking down process (uptake and release of calcium). PTH release is signaled when blood calcium levels fall. PTH then goes to the bone to control the pausing of osteoblasts (bone-building organisms) and the release of osteoclasts to break down bone and release calcium into the bloodstream.
One other co-factor I would like to mention in closing is the delicate balance of all minerals in our body. Calcium has the largest concentration in our bodies but works in harmony with other minerals. Namely, magnesium, potassium, and phosphorus among others. When these minerals are out of balance with calcium, and each other, it affects the uptake, or absorption, of all of them. If you are a soda drinker, you are likely getting too much phosphoric acid and this imbalance can show up in bone spurs or arthritis for example. Excess sugar consumption, depletes magnesium and other minerals as well, which inhibits the hundreds of processes they are needed for.
In closing, our bodies are beautiful, very complex systems. Their creation and endurance show the numerous fail-safes that are in place despite the stressors we place on them. With a little knowledge here and there, we can know better how to help our bodies achieve wellness rather than succumb to chronic illness.
