Sodas have no nutritional value, contain high amounts of phosphates, and tremendous amounts of white sugar and chemicals. They can easily deplete the body of nutrients and can cause weight gain and promote high levels of obesity. Sodas often contain artificial flavouring, colouring and sweeteners, all of which are highly cancer causing substances. Among artificial sweeteners, Saccharin is the greatest concern.
Research studies have linked it with cancer in lab animals as a cancer initiator and promoter. Another sweetener, Aspartame is widely used in soft drinks. Furthermore, research studies found it caused brain tumours in lab animals.
Sodas also happen to be quite acidic, and when packaged in aluminium cans, can leak fairly high amounts of aluminium. Aluminium itself has been connected with weakening the gastrointestinal tract and with Alzheimer’s disease, there are increased aluminium levels in the brain tissue.
