Water plays an important role in good brain functioning. Our bodies require water to hydrate the blood and tissues, lubricate our joints, regulate temperature, and moisten the lungs to allow for breathing. So those stiff joints may actually be a lack of proper hydration!
Our digestive system is too often underestimated, it breaks down the foods we eat into the nutrients our body needs. By neglecting our digestive health, our body will likely run into problems absorbing those nutrients.
