My best suggestion: remove ALL diet sweeteners and food chemicals from your home, and return to a natural diet with a history of little to no harm to your child's health and safety. Also, insist that ALL diet soft drinks and flavored waters be removed from the public schools K-12. Talk to your children, and teach them which foods are real and healthy for them, and which foods are manmade, phony replicas of nutrition, resulting in damage to their growth and maturity. To your health! There you go. I think she has an agenda. Eating healthy is fine, just don't be a food Nazi.
