A surprising number and variety of physical problems and diseases can be caused by acidity. Today, the vast majority of the populace in industrialized nations suffers from problems caused by acidification, because both modern lifestyle and diet promote acidification of the body’s internal environment.

In general, the current standard diet is primarily composed of acidic or acidifying elements (proteins, cereals, sugars). Alkaline foods such as vegetables are eaten in much smaller quantities; their alkaline content is insufficient to neutralize surplus acids. Stimulants like tobacco, coffee, tea and alcohol are also extremely acidifying. Stress and physical activity (both insufficient or excessive amounts) also cause acidification.
