Avoid foods with Aspartame
Most people probably don’t know what Aspartame is. It’s a sweetener found in a lot of processed food and drink, candies and gum. There is a controversy around aspartame which is whether its chemicals, or byproducts are carcinogens, cancer-causing agents, from ingestion of the chemicals or the reaction and change in them that occurs during digestion. Read the Wikipedia entry on the Aspartame controversy, and please check the label on any goods that are sweetened without sugar. It’s probably Aspartame, or Splenda. Probably avoid both of them. Diet Coke would be the most popular product using it.
You don’t have to listen to me though. Research for yourself. I think you’ll find that interestingly products containing Aspartame aren’t anything remotely important in your nutrition anyway, so it’s very logical and easy to avoid them. Diet Soda? I mean come on. You want diet soda? It’s called water, or even tea. Add a little lemon if you like.
