Unfortunately there is a tendency to lace this vital fluid with a plethora of less desirable substances. Some contain up to 240 calories per 8-ounce serving. We can get our supply of carbohydrates in the foods we eat. We don't need them repeated in our beverages. I recommend distilled water as the main source of beverage.
Distilled water is devoid of micro-contaminates that are inherent in virtually are other sources.
We have many pathways to convert what we eat into what we need. The beauty of this is that even the most bizarre perversions of diet aren't overly harmful. Very little long-term research has focused on the whole of dietary intake. The Framingham study showed us that the earlier we correct our diet, the better our long-term prognosis will be. In other words, the earlier in life we start to take in balanced nutrition, the better off our later years will be in terms of health.
