Rubbish or junk foods do not provide our body with the essential nutrients, but harm our health as well as weakened our immune system. I won't explain further on this topic as it has written brilliantly by a Triond's writer, Judy Sheldon on her article entitled The Top Foods to Avoid.

This type of food contains very high proportion of “Triphenyl Sibing topiramate”, a carcinogenic substance that causes cancer. This chemical substance is found in the barbecue, grilled or roasted meats. When this chemical compound comes to contact with the stomach, and the gastric mucosa, the possibility of getting gastric cancer is always very high.
While in the process of grilling or roasting food, many processing environmental conditions are always unfavorable, as the meats might have contaminated with bacteria, parasites or might even uncooked thoroughly during the entire food handling process. A roasted meat is equivalent to the toxin of as much as 60 cigarettes.
