How Many Calories $1 Will Buy
A good illustration of one of the problems with the American diet: unhealthy food is often a lot cheaper than healthy food.
One dollar’s worth of Coke has 447 calories, while $1 of iceberg lettuce has just 16.5. To look at it another way, you would have to spend about $5 to buy 2,000 calories at McDonald’s, $19 to buy 2,000 calories worth of canned tuna and $60 to buy 2,000 calories worth of lettuce.
