Just as a neat little experiment for your own information.
Make a list of all the food commonly eaten by your family on a regular basis and then cut out all the processed stuff for about a month or 2 and see what results you experience.
Soda pop, white bread, margarine, canola oil, white sugar, condiments and sauces, fast foods, snack foods, deli meats and sausages, etc, that kind of stuff.
You can find good lists on the internet.
Replace with whole, fresh, made from scratch foods that are definitely good (and there are many lists available with a little searching around)
You have heard all the claims and nay-sayers, so the only way to really "know" is to do the experiment for yourself and see the results.
You found out that the aspartame was a real detriment to the health and now you "know"...you have only just started to take back your health.
