What would you guess is your most important nutrient? It’s WATER because your body cannot manufacture it! You can live much longer—maybe ten times longer—without food than without water. In general, the brain and body follow the same ratio as does planet Earth: 75% water, 25% solid matter. Muscle cells are 75% water, Overall the brain is 75% water but brain cells are 85% water. According to Mayo Clinic, the average adult loses more than 80 ounces (ten eight-ounce glasses of water every day through sweating, breathing, and waste elimination. The average adult drinks less than four eight-ounce glasses of water each day, which puts them six eight-ounce glasses in the hole. And that’s deady for your brain and body. When you are “in the hole” in terms of water intake, you risk the undesirable consequences of dehydration. More tomorrow.
