Diet Sodas - How Many Can We Drink?

Questions and anxieties about drinking too many diet sodas (containing aspartame) came up in our family recently. The main concern was whether it caused cancer. After some research into the scientific literature, the evidence, after 25 years of aspartame consumption in the world, is that the risk of a health hazard is vanishingly low within the FDA allowance (except if you are on a phenyalanine-restricted diet) and that lowering our energy intake by sucrose replacement helps in weight reduction and management. The safe number of diet sodas per day for an adult is much more than what we would normally want to drink.
