Organic food is expensive. I decided to look up a few foods I commonly eat to determine which ones are more cost effective.

Organic spinach — $0.80/ounce, 7 calories/ounce = 9 calories/dollar

Organic zucchini (cooked) — 80 calories/pound, $1.99/pound = 40 calories/dollar

Organic carrots (raw) — 175 calories/pound, $1.29/pound = 135 calories/dollar

Organic apple — about 127 calories per apple, at $1.50/pound is $0.74/apple = 172 calories/dollar

Organic yogurt — 680 calories for $3.89 = 175 calories/dollar

Organic eggs — 840 calories for $3.70 = 227 calories/dollar

Organic milk — 1 gallon (2400 calories) for $6 = 400 calories/dollar

Organic peanut butter — 2700 calories for $5 = 540 calories/dollar

Organic beans (dried): 840 calories/pound, $1.39/pound = 600 calories/dollar

Peanut butter and beans are the winners for density. It turns out peanuts are legumes after all, so perhaps it’s no surprise that they are comparable. Greens are like eating water, calorically speaking.
