Potato chips are fried in low quality, unhealthy, potentially rancid oil, are too salty, and don't contain much in the way of micronutrients. Imagine 3 weeks ago someone took some potatoes, cut 'em up, and fried them in the cheapest Wal Mart oil around. They used that oil for a while, too (don't worry, there's some potentially cancer-causing chemicals in the oil to stop it from tasting too bad when it gets old). Then they bagged those chips up and sent them your way.
Peanuts aren't the best choice as far as nuts go, anyway. You'd be better off with raw almonds or dry roasted cashews.
