Experts believe that lemon water can help reduce the amount of uric acid in joints, which is one of the underlying causes of certain types of joint pain.
For example, according to Harvard Medical School, "an attack of gout occurs when excess uric acid is deposited in a joint and forms urate crystals that irritate the joint lining. White blood cells try to gobble up the crystals, but they are not equal to the task. The white blood cells are themselves damaged, releasing chemicals that cause inflammation, swelling, and pain."
Drinking lemon in water can also help to remove other metabolic and acidic wastes from the body. It will also help to alkalize the body and control the proliferation of unhealthy bacteria and viruses.
