The acidic environment of the stomach is not only necessary for processing food, but it also helps to protect your body from pathogenic organisms or food antigens that shouldn’t be there. Interestingly, many people with acid reflux and heartburn — a condition conventional medicine blames on acid-containing foods like fruits and vegetables — actually have too little acid in their stomachs, a problem that’s compounded by medications like Pepcid and TUMS that increase alkalinity in the stomach. As food makes its way from your mouth to your stomach, the digestive tract becomes more acidic. Pepsin, the enzyme responsible for protein breakdown, needs an acidic environment and therefore gets released into the stomach, where pH is very low (about 2.0–1.5). Your small intestine is where most of the nutrients in your food get absorbed, and where the pH increases from 2.0 to 6.5 as the food travels from the stomach to the small and large intestines. Protein (particularly in the form of red meats), requires huge amounts of alkaline minerals for complete digestive processing. When the system goes looking for the alkalinity needed to offset the acid load, it looks first to the minerals currently in the digestive tract. If it fails to find alkaline nourishment there, it draws on the calcium, magnesium, phosphorus and potassium minerals stored in our bones. This is where the good greens and essential vitamins and minerals come in. When we eat a diet that is rich in nutrients, there’s no need to draw on the stored minerals in the bones. It’s when we don’t consume a nutrient-rich diet or worse when we over consume foods that promote acidity in the body that we start tapping our bone resources. In the short term, this isn’t an issue, but in the long run, it can have serious consequences, not just for our bone health but for our overall health.
