Healthy Foods for Under $1
I've never understood why folks will spend 20 minutes in line during the lunch rush for a "fast" food burger, when in the same amount of time they can run into the grocery store, grab an apple, a bottle of Odwalla, and a block of cheese or the like, for the same amount of money. It has to be the perceived convenience of not picking out the components and assembling them oneself, along with the perceived "value" of the dollar menu.
Maybe if the cost of a quad bypass was factored into the 99 cent burger, folks would figure it out.
There are some obvious things one can do to both save money and eat better. For under three bucks, you get a tub of oats that will make five to ten times the cereal that you would get in a three dollar box of Sugar Coated Choco Bombs. But the packaged cold cereal is much more convenient, and we've become the laziest consumers on the market. (For that matter, a three dollar tub of oats will make ten times the oatmeal as those individual packets of oatmeal from the same manufacturer that cost a little bit more — explain that one to me.)
Instead of big box cereals, buy these items in bulk and try this out.
