I think some of your prices are quite low, but for comparison&#x27;s sake, I&#x27;ll just assume they are correct.  I pulled calorie counts from the USDA and from calorieking.com<p><pre><code>  1 pound dried pinto beans - 636 Calories, $1.00
  1 pound raw cabbage - 120 Calories, $0.50
  1 pound frozen spinach - 108 Calories, $1.40
  1 dozen large eggs - 840 Calories, $1.00
  1 pound chicken breast (with skin) - 780 Calories, $2.00

  Total: 2484 Calories, $5.90 or 421 Calories per dollar

</code></pre>
I went to Wal-Mart.com to find some junk food and grabbed a couple of the first items I saw that kept me to about $6 and had online availability (so I could get accurate pricing).  I pulled calorie counts from the Kellog website and walmart.com since I had exact branded items.<p><pre><code>  1 dozen limited edition frosted pumpkin pie pop tarts - 2400 Calories, $3.50
  13oz chips ahoy chocolate chip cookies - 1760 Calories, $2.50

  Total: 4160 Calories, $6.00 or 693 Calories per dollar

So assuming your prices are correct, you get 65% more food per dollar if buying name-brand junk food without even trying.  You could push these prices even lower if you buy generic.  You can also sub in a number of different &quot;junk food&quot; options and get similar results (e.g. chips look similar to the cookies, soda should work out in the same ballpark as well).<p>[1] <a href="http:&#x2F;&#x2F;www.walmart.com&#x2F;ip&#x2F;Kellogg-s-Pop-Tarts-Frosted-Pumpkin-Pie-Toaster-Pastries-16ct&#x2F;19890848" rel="nofollow">http:&#x2F;&#x2F;www.walmart.com&#x2F;ip&#x2F;Kellogg-s-Pop-Tarts-Frosted-Pumpki...</a>
