Processed foods make up 50 percent of the current American diet. Though they are inexpensive and
convenient, especially when you are in a hurry and just
don't have time to make dinner from scratch, processed
foods are unhealthy and contribute to a variety of health
problems. A diet high in processed foods such as boxed
macaroni and cheese, which are yummy but really not
good for you, has been linked to both diabetes and obesity.
Processed foods are also sources of Butylated
hydroxytoluene (BHT) and Butylated hydroxyanisole (BHA),
two chemical additives that sound very scary and which
are known to cause cancer in humans.
