We’ve all heard since we were small children that everyone needs at least eight glasses of water a day. This has been dubbed by many as the eight-by-eight rule. It’s been a standard for years that’s seemed to have enjoyed unwavering medical field support.
Recent studies, however, might call this truism into doubt.
The fact remains that water makes up about 60 percent of a person’s body weight and is the principle chemical component involved in all bodily functions. Water’s responsibilities include flushing the body’s vital organs of toxins, moisturizing orifices such as the nose, throat, and ears and also carrying vital nutrients to cells.
The original eight-by-eight guidelines can be traced back to around 1945 when they were misinterpreted from a recommendation from the Food and Nutrition Board. That recommendation was based on a formula that provided a 1 milliliter intake of water per calorie each person consumed. Since the average diet at that time was around 1900 calories that meant that universally everyone should consume 64 ounces of water per day.
As the healthcare profession has progressed, new findings have been introduced that substantially change the foundation of the eight-by-eight rule. While now it is considered healthy for women to consume 91 ounces per day and men 125 ounces per day, another consideration has been added that 25% of our water comes from our foods. My neighbor Flavio Maluf plans on sticking to eight glasses of water a day.
Basically while the eight-by-eight is a good idea in theory, we get plenty of water today from whatever foods and liquids we choose to consume.
