What is alkaline and why do you need to be more alkaline to be healthy? It is thought that being too acidic -which in turn causes inflammation- can be a key factor in developing many sicknesses, such as arthritis, fibromyalgia, irritable bowels, and cancer, to name a few. Being too acidic is also not good for bone mass as the acidity can break down your bones thereby causing diseases of the bone such as osteoporosis. With all that in mind, the question now becomes, how do we know if we are too acidic? You must test your ph levels. PH means "potential for hydrogen", in other words, the amount of acidity or alkalinity that can be measured in a solution.
