SEATTLE — A healthy diet is expensive and could make it difficult for Americans to meet new U.S. nutritional guidelines, according to a study published today that says the government should do more to help consumers eat healthier.
An update of what used to be known as a food pyramid in 2010 had called on Americans to eat more foods containing potassium, dietary fiber, vitamin D and calcium.
Inexpensive ways to add these nutrients to a person’s diet include potatoes and beans for potassium and dietary fiber. But the study found introducing more potassium in a diet is likely to add $380 a year to the average consumer’s food costs, said the lead researcher of the study, which appears in the journal Health Affairs.
