A recent study by a research team from Dartmouth's Geisel School of Medicine reveals that the TV Parental Guidelines rating system developed by the entertainment industry more than 20 years ago has been ineffective in helping parents identify shows that
contain content that might not be appropriate for children, including
tobacco and alcohol use — behaviors strongly associated with increased cancer risk.
From a health perspective, nutrient - free sugary cereals, candy bars
and any food products
containing high - fructose corn syrup may be imposing as much or more health externalities as
tobacco and alcohol products.
