Yes, it is possible to improve your diet without increasing your spending.
Great news for anyone who wants to save money and eat healthier—in other words, pretty much all of us. A new study suggests that it really is possible to do both at once.
The secret? Cook more at home. Researchers at the University of Washington School of Public Health found that families who had this one thing in common tended to eat better without spending more on food than families who cooked less.
For the study, published in the American Journal of Preventive Medicine, researchers interviewed 437 adults living in and around Seattle, asking them what they ate in the last week and where. They also gathered information about participants’ income, employment, family size, and other demographics. Overall, they found that people who cooked more often met more of the federal guidelines for a healthy diet. And while home-cooked meals were associated with diets lower in calories, sugar, and fat, they weren’t associated with higher grocery bills.
Researchers are further analyzing participants’ diets to determine the best real-world strategies for eating healthy on a budget. “Not all fruits and vegetables are equally expensive,” says study co-author Anju Aggarwal, PhD, acting assistant professor of epidemiology. “So instead of buying the most expensive fruit, maybe you buy bananas and oranges. Maybe you start eating more whole grains, and you eat less fat and sugar.”
“As long as you know which food groups to pick from, how much to eat, and how to cook it, you can improve your diet without increasing your costs,” she adds.
