These are guidelines that health authorities are endorsing because fruits and vegetables contain a variety of vitamins and minerals that are necessary for health and well being. The modern diet is sparse in live nutrients from good soil.
Malnutrition is an ongoing problem.
Modern day diets are very acidic making it difficult for the body to reach a healthy ph balance. To correct our dietary deficiencies, the need for alkaline reactions to take place so a balance within our bodies is possible. There is a need for a diet rich in green leafy vegetables with phytonutrients in plants containing chlorophyll, which promotes photosynthesis, which in turn creates the oxygen we breathe, and the food we eat. These vital nutrients are essential for survival. The Food and Drug Administration has not evaluated these statements.
