Many foods that we eat contain water to some extent and various fluids also add to the water intake of our body. Milk, fruits and vegetables are also rich sources of water. So, one should incorporate these foods to the diet as often as possible. Our body is made up mostly of water and approximately 85% of our brain, 80% of our blood and 70% of our muscle comprises of water. Moreover, every cell in our body needs water to live. So, one should make it a habit of drinking as much water as possible, preferably a minimum of 8-10 glasses regularly. The best part of water is that excess intake won’t increase the waistline, as its calorie count is absolutely zero.
