The new dietary recommendations are aimed at fighting obesity rates.
Americans are urged to eat more foods containing potassium, dietary fiber, vitamin D and calcium. But that can add hundreds of dollars to the average person's grocery bill over a year.
However, it appears those consumers are getting the most nutritional bang for their bucks.
A survey of 2,000 adults in Washington State found that those who spend the most on food get the highest amounts of potassium, dietary fiber, vitamin D and calcium.
Those who spend the least, eat the most saturated fat and added sugar.
The study appears in the journal Health Affairs.
