In fact, carrots, onions, pinto beans, lettuce, mashed potatoes, bananas and orange juice are all less expensive per portion than soft drinks, ice cream, chocolate candy, French fries, sweet rolls and deep-fat fried chicken patties, the report says.
"We have all heard that eating a healthy diet is expensive, and people have used that as an excuse for not eating a healthy diet,. . .but healthy foods do not necessarily cost more than less healthy foods," says Andrea Carlson, an economist and co-author of the report from the U.S. Department of Agriculture's Economic Research Service.
"The price of potato chips is nearly twice as expensive as the price of carrots by portion size," she says.
Carlson and and her colleague Elizabeth Frazão gathered national pricing data on more than 4,000 foods and then ranked the foods by price based on calories, weight and portion size.
They placed the foods into the five food groups -- grains, dairy, protein, fruits and vegetables. They added a category for unhealthy foods, which included items that did not fit the other categories or were high in sugar, sodium and/or saturated fat such as cookies, candy, desserts, granola bars and many ready-to-eat cereals.
When using weight and portion size as the guide, many healthy foods were not any more costly than unhealthy ones, Carlson says. You can always find healthy foods that are cheap and healthy foods that are expensive. The same is true of less healthy foods, she says.
She says one of the best ways to think of food costs is to consider portion size: "How much do you have to pay to put something on your plate?"
Overall, the economists found:
• When considering portion size, the ranking from least to most expensive is: grains, dairy, vegetables, fruit, protein and less healthy foods. Protein and less healthy foods are very close in cost.
• Grains, such as bread, oatmeal, pasta and rice, are the cheapest foods no matter how you measure by portion, weight or calories.
• Protein, such as meat, chicken and fish, is the most expensive food by portion size, but there are low-cost proteins such as beans and eggs.
• When looking at price per portion, fruits and vegetables are lower in price overall than unhealthy foods. "Like every food group, there are cheap veggies and fruits, and pricey ones," Carlson says. "Cheap unhealthy foods and more expensive ones."
• When trying to eat a healthy diet based on the government's dietary guidelines, protein and vegetables are the most expensive recommendations to meet, followed by fruit, she says. One of the reasons: The vegetable recommendation has high amounts, about 2½ cups for someone eating a 2,000-calorie-a-day diet, and so it takes a lot of food to meet that goal, Carlson says.
Previous research has just looked at price per calories and found that healthy foods are more expensive, but Carlson says price per calorie is not a fair measure. For example, non-fat milk has a higher price per calorie than 2% milk but most health experts recommend drinking non-fat or 1% milk, she says. "Whole milk and skim milk are about the same price per gallon at the grocery store."
Another example: a half cup of broccoli has 27 calories, while a one-ounce bag of potato chips has 154 calories. To consume 100 calories of broccoli, one would have to eat almost two cups, and that is more than what most people normally eat in one sitting, she says.
Most people allocate only about of 20-25% of their food budget to fruits and vegetables, but the government recommends that it should be more like 40%, Carlson says.
Dawn Jackson Blatner, a registered dietitian in Chicago and author of The Flexitarian Diet, says the latest report "is great information to help bust the myth that it costs too much to eat healthy."
Cynthia Sass, a registered dietitian in New York City and author of S.A.S.S.! Yourself Slim, says, "Many of my clients are surprised to find that their grocery bills don't go up when they swap processed goods for fresh foods, especially when they buy in-season produce and they're eating ideal portions, meaning three ounces of cooked chicken, rather than six."
Just giving up soda to drink fresh-brewed hot or iced tea, or water with a wedge of in-season citrus fruit can be a huge cost savings, she says. "And many of the healthiest superfoods in the market are inexpensive, such as beans and brown rice."
Adam Drewnowski, director of the Nutritional Sciences Program at the University of Washington and lead author of a 2010 study that showed calorie-for-calorie junk food is more cost-effective than eating healthy, said he stands by his findings that a healthier diet generally costs more.
