There’s no getting around it: a healthy diet is more expensive than an unhealthy one. But that doesn’t mean your food choices should be limited to the dollar menu at your favorite fast food joint. Add some cheap superfoods to your diet and you’ll be making healthy choices that also fit within your grocery budget.
“You’ll get more bang for your buck,” says Angela Ginn, registered dietician nutritionist and spokesperson for the Academy of Nutrition and Dietetics. Superfood is just a catchy term that’s being thrown around to refer to foods that are “nutrient-rich” says Ginn.
Here’s are some cheap superfoods to add to that unhealthy diet of refined carbohydrates and processed meats you’ve got there, with average prices and Ginn’s rundown of the nutritional benefits for each.
