Alkalinity, referred to as pH, is the concentration of hydrogen ions in water, blood, etc… A pH of 7.0 on the scale is considered neutral, but a 7.4 pH is desirable for the human body.
You get alkaline by eating raw foods, fruits and vegetables. The acidic foods on the other hand are sugar, white flour, red meats, and processed foods. Stress can also cause your body to be acidic. A normal American diet is 80% acid and 20% alkaline; this is the opposite of a good diet. If you reverse those numbers you will be giving your body what it desires.
Your blood pH must operate in a narrow range for good health. The complex biochemical processes taking place constantly is an attempt to keep blood pH as near perfect as possible. If your body is not getting an adequate mineral intake from the foods you eat, you will have problems balancing your pH system. When the body is overly acidic it will leach calcium from the bones or teeth leading to osteoporosis and other health problems.
An easy way to get enough minerals to keep your body alkaline is by taking the only wheatgrass powder with the roots. Wheatgrass will assimilate into your blood stream in about 20 minutes. This is like getting a blood transfusion with every drink of wheatgrass.
All wheatgrass powders are not the same, be sure and get the only one that includes the roots.
