How to avoid aspartame
Check the labels of processed foods.
On the back of your food products, read the ingredients or " inactive ingredients " section. It is a small section underneath the " nutrition facts " section.
If you see either the word " aspartame " or " phenylalanine " then the product contains aspartame. Some products even have a warning that indicates people with phenylketonuria (pku) should avoid the product.
