It is no surprise that soda destroys our immune system. The high sugar level of soda can accelerate the releases of insulin and cortisol, which lowers the production of white blood cells and weaken the immune system. Excess sugar will be transformed into fat that hinders the absorption of nutrients and increases the burden of the digestive system.
