I consume an average of 2 or 3 cans per week. I do not believe that it will have an apprecaible effect on my health. I do always keep an open mind on issues though. It just so-happens to be that the evidence I see points to aspartame being safe. Can I prove this? No, of course not. Any individual who has any concept of the Nature of Science (NOS) will be able to indenitfy that there is indeed no such concept as proof. There is merely evidence from various sources that get mounded against one another. Do we have to consider bias in research? Certainly. Have I considered it at this point? To an exten yes. And based on what I have seen presented from both sides of the coin, I would contend that aspartame is indeed fine for consumption. The negative effects it may possess are negligble in the short term and long run. Is it healthy? No, I have yet to read anything to suggest that aspartame will yeild some sort of health benefit. This in its own might be enough for people to avoid its useage. However, for the overwhelming majority of people, consider the alternative. A 355ml can of traditional soda contains typically 35-45 grams of sugar. Whats worse? A pinch of aspartame or 6 tbsp of sugar?
