Potato chips are more often made from reconstituted potatoes than fresh ones, which is outwardly similar to washing powder. Rice or corn flour is first added to this. Acrylamide, a carcinogen, accumulates during the process of thermal processing of the potato chips. Some brands of potato chips have been found to contain amounts of this chemical that exceed safety levels (0.2 µg per kg) by 1,000%.
Advice: Potato chips made from whole potatoes contain more oil because they are fried, whereas those made from reconstituted potatoes are usually baked.
