In a multinational meta analysis that was published recently in BMJ, Harvard medical school researchers compared the cost of healthy vs. unhealthy diets in 27 studies from 10 countries. Price differences varied according to food groups from which meats/proteins had the largest price difference costing an average of $0.29 more per serving than less healthy options. Other categories such as grains, dairy, and snacks/sweets also cost more for healthier options, at $0.03, $0.004, and $0.12 respectively. On average, the study concluded that a day’s worth of healthiest diet cost about $1.50 more than the least healthiest. What do you think of this research? Are you surprised by the amount of difference?
