Following a healthy diet runs about $1.50 more a day than junk food, study finds
By Brenda Goodman
FRIDAY, Dec. 6, 2013 (HealthDay News) -- Does it really cost more to stick to a healthy diet? The answer is yes, but not as much as many people think, according to a new study.
The research review combined the results of 27 studies from 10 different countries that compared the cost of healthy and unhealthy diets.
The verdict? A diet rich in fruits, vegetables, nuts and fish costs a person about $1.50 more per day -- or $550 per year -- compared to a diet high in processed grains and meats, fat, sugar and convenience foods.
By and large, protein drove the price increases. Researchers found that healthy proteins -- think a portion of boneless skinless chicken breast -- were 29 cents more expensive per serving compared to less healthy sources, like a fried chicken nugget.
The study was published online Dec. 5 in the journal BMJ Open.
"For many low-income families, this could be a genuine barrier to healthy eating," said study author Mayuree Rao. She is a junior research fellow in the department of epidemiology at the Harvard School of Public Health, in Boston.
For example, a family of four that is following the USDA's thrifty eating plan has a weekly food budget of about $128. An extra $1.50 for each person in the family a day adds up to $42 for the week, or about 30 percent of that family's total food tab.
Rao says it wouldn't be such a big difference for many middle-class families, though.
She said that "$1.50 is about the price of a cup of coffee and really just a drop in the bucket when you consider the billions of dollars spent every year on diet-related chronic diseases."
Researchers who weren't involved in the review had plenty to say about its findings.
"I am thinking that a mean difference in cost of $1.50 per person per day is very substantial," said Adam Drewnowski, director of the nutritional sciences program at the University of Washington, in Seattle. He has compared the cost of healthy versus unhealthy diets.
