8. BHA and BHT
These are common preservatives found in foods like cereals, potato chips, chewing gums and vegetable oils. Adding BHA and BHT into foods keeps it from changing color or flavor and prevents it from becoming rancid. This happens as both BHT and BHA prevent oils in foods from oxidizing.
Both additives are oxidants that are believed to form cancer causing reactive compounds in the body. Continuous consumption has also been linked to affecting the neurological system of the brain by altering behavior.
