Earlier studies have shown the connection between junk food and various diseases. Recent study has shown that chips, which fall in junk food category, can help in fighting certain types of cancers like cancer of the esophagus, cancer of the stomach and breast cancer as well.

Fiona Hunter, a nutritionist said: "Free radicals are very unstable molecules which can cause damage within the body and are linked to several different types of cancer."

Research team found that a 175g serving of potato chips has a vitamin C content that is three times more than that of an apple and five more than that of grapes. Chips can also help people already suffering from the disease by decreasing the size of their tumors. Chips also contain a host of other nutrients including vitamins B1 and B6, fibre and iron.

Hunter said, "There's no such thing as a bad food. Chips can be part of a healthy, balanced diet. "

Research team said that this study doesn't mean that people can consume huge quantity of chips. Everything is good in limit.
