Right, I was wrong. The best calorie/$ ratio is with a bottle of cooking oil. (7-9k calories/$) But you cannot eat that, so potato chips are a distant second (

Right, I was wrong. The best calorie/$ ratio is with a bottle of cooking oil. (7-9k calories/$) But you cannot eat that, so potato chips are a distant second (at least from the products I checked) And no, the calories in chips added by the oil offset the lesser amount of weight you buy per unit - at least in my locality. If I just look at calories per dollar, potato chips seem the most cost effective - at least as long as you take the cheapest ones Pure potatoes are somewhere around 200-500 calories per dollar, cheap potato chips are around 1000/dollar Pure noodles or rice might be even better, I didn't check those admittedly.
