Certain food preservative such as BHA and BHT used for edible oils act as antioxidants.In India specially people feel it is bad to consume food that contains amounts of preservatives and deem to be unhealthy , but this is not exactly true..in maximum cases these producta are released into the market after passing through multiple screening tests and also only after Food Corporation gives it the allowance to be sold in market.As u know anything in excess leads to abrupt problems and health issues but when it is utilized under proper proportions it acts more as a boon that a bane.!
