cost of healthy eating
Eating healthy costs $1.50 more per day only if your time has no value. Fresh food has to be prepared, and that takes time and effort. The true cost of fresh food has to factor in the value put into its preparation, and that's why so many people eat out.
Over the course of a year, $1.50/day more for eating a healthy diet would increase food costs for one person by about $550 per year.
