Somebody told me today that they can't eat right because eating healthy costs more. I hear it every month, usually from someone holding a 24-ounce energy drink. So let's settle it with evidence instead of feelings: does eating healthy cost more? For the way most people actually eat, no. It costs less.
This matters because "I can't afford it" is the most respectable excuse there is. Nobody argues with money. It shuts the conversation down, and it keeps good people stuck in a cycle of drive-thru lunches, afternoon crashes and weight that won't move, all while believing the healthy version is out of reach.
Below is what the research really says, including the one study that seems to say the opposite, where the money actually goes, a realistic week of spending side by side, and the psychology of why people always find money for what they truly want. Then a plan you can start this week.
- ›Junk food is only cheaper per calorie; per portion and per gram, grains, vegetables, fruit and dairy are cheaper than most protein foods and foods high in fat, sugar or salt.
- ›The best-known study found the healthiest diets cost about $1.50 more per day than the least healthy, which is less than one gas-station soda.
- ›Adults who cooked dinner at home most nights spent less on food per person than infrequent home cooks, $273 versus $330 a month, and ate a measurably better diet.
- ›The average U.S. household spends about $3,945 a year eating out, roughly $76 a week, so the money for healthy groceries usually already exists.
- ›Cut sweetened drinks first, cook dinner at home five nights a week, and build meals on beans, rice, oats, eggs, potatoes, frozen vegetables and fruit.
The Study Everyone Quotes, and What It Actually Found
If you search this question, you will find headlines saying healthy food really does cost more. They come from a 2013 Harvard-led meta-analysis in BMJ Open that pooled 27 studies from 10 wealthy countries. It found the healthiest diet patterns cost about $1.48 more per person per day than the least healthy ones, roughly $550 a year. That is real, and I'm not going to pretend it isn't.
But read the number again. A dollar and a half a day. That is one convenience-store soda, or half of a coffee-shop drink. The same study found that when diets were ranked by nutrients instead of food groups, the daily price difference between the healthiest and least healthy patterns was essentially zero: four cents. The gap people quote is smaller than the cost of the habits they're defending.
The other half of the story is how price gets measured. A USDA Economic Research Service report priced 4,439 foods three ways: per calorie, per edible gram and per average portion. Only per calorie did junk food come out cheaper. By weight or by the portion people actually eat, grains, vegetables, fruit and dairy were cheaper than most protein foods and foods high in saturated fat, added sugar or sodium.
That's the trick hiding inside "healthy costs more." Chips win if your goal is to buy as many calories as possible per dollar. Nobody's goal is that. Your goal is to feel full, have energy for training and stop gaining weight, and on those terms cheap calories are the most expensive food in the store.
The Grocery Math: Real Food Is Already Cheap
USDA ran the numbers on produce specifically. Using 2022 retail prices, its analysts found a person could meet the full daily fruit and vegetable recommendation for about $2.50 to $3.00 a day. Watermelon came in at 24 cents per cup equivalent, baked potatoes at 27 cents, onions at 43 cents and canned tomatoes at 58 cents. In USDA's 2023 data, dried pinto beans were the cheapest item of all 155 it tracked, at 23 cents.
The same analysis put another myth to bed: fresh is not always the expensive option, and frozen or canned is not always the cheap one. Neither won consistently. Frozen spinach, canned tomatoes and frozen mixed vegetables are every bit as useful in a weeknight meal as fresh, and they don't rot in your fridge before Friday.
Now compare that with the drive-thru. McDonald's own figure for a Big Mac meal was $9.29 nationally in 2024, before island pricing. That single lunch costs more than three full days of fruits and vegetables at USDA's estimate, and it leaves you hungry by 3 p.m.
There's also a hidden cost the per-calorie math never counts: how soon you're hungry again. Meals built on protein, fiber and water-rich food, like beans, eggs, vegetables and fruit, keep you full for hours. Chips, pastries and soda digest fast and send you back to the counter by mid-afternoon. When the cheap meal needs a second purchase two hours later, it was never the cheap meal.
Build your cart around the boring winners: dried or canned beans, rice, oats, eggs, potatoes, onions, bananas, frozen vegetables, canned tuna or salmon, and whatever local produce is in season. None of it is trendy. All of it is cheap, filling and exactly what fuels the work we do on Warrior Field.
Where the Money Actually Goes
Here is the part that should end the argument. According to the Bureau of Labor Statistics, the average U.S. household spent $6,224 on groceries in 2024, and another $3,945 eating out, about $76 every week, plus $643 on alcohol. USDA reports that more than half of all American food dollars now go to food away from home. The money for better groceries isn't missing. It's already being spent, just at the counter instead of the store.
A large USDA study of household grocery purchases (older, from 2011 receipts, but the pattern hasn't changed) found that more money went to soft drinks than to any other single item, about 5 percent of food dollars, and sweetened drinks as a group, including juices, energy drinks and sweet tea, made up nearly 10 percent. The first place most people's food budget leaks isn't kale. It's the drink cooler.
The best real-world evidence comes from a 2017 study in the American Journal of Preventive Medicine. Researchers in Seattle tracked 437 adults' cooking habits, diet quality and food spending. People who cooked dinner at home most nights ate a significantly healthier diet and spent less per person on food overall: $273 a month, against $330 for people who rarely cooked. Frequent restaurant eaters spent the most of anyone, $364 a month, and ate the worst.
Read that once more. Better diet, lower spending, and income didn't decide who cooked. The thing that predicted it was the habit, not the bank balance.
Meet Kai: The Week That Costs More Than Eating Well
Kai is a composite of people I've coached, not one person. He works full time, says he can't afford to eat healthy, and spends his week like this: a gas-station energy drink and chips on the way to work, a drive-thru combo for lunch, a soda and a snack to fight the 3 p.m. crash, and takeout twice a week when he's too tired to cook.
Price that honestly at Oahu prices and it adds up fast. Five lunch combos at about $11 is $55. Ten energy drinks and sodas at about $3 is $30. Snacks run $15. Two takeout dinners are another $40. That is about $140 a week, and it doesn't include breakfast, groceries or a single dinner he cooks himself. Your numbers will vary, but most people who track it are shocked.
Now look at USDA's own budget for eating well here. Its Hawaii Thrifty Food Plan, the government's cost estimate for a healthy diet on a tight budget, priced a family of four at $1,428.50 a month in May 2024. That works out to roughly $83 per person per week, for every meal, every day, in the most expensive food state in the country. Adults run a bit above that average, but not $140 above it.
Here is Kai's other week. On Sunday he spends about an hour cooking: a pot of rice, a pot of beans, a sheet pan of chicken thighs and frozen vegetables, and a dozen boiled eggs. He buys oats, bananas, canned tuna and a bag of apples for the week. That single grocery run covers breakfasts, packed lunches and most dinners, and it's exactly the kind of food USDA's budget plan is built on. He still grabs a plate lunch on Friday with the crew. He just stopped paying drive-thru prices five days a week for food that left him hungry.
Kai doesn't have a money problem. He has a spending pattern that costs more than eating well would, and leaves him tired, hungry and heavier. Swap the drinks for water, pack lunch from a Sunday batch cook four days out of five, and cook most dinners, and he eats better for less.
Why People Always Find the Money for What They Want
Economists have a name for what Kai is doing. Richard Thaler, who won a Nobel Prize for this work, called it mental accounting: people sort money into separate mental buckets and treat each one differently. Groceries come from the "bills" bucket, where every dollar hurts. The energy drink, the combo meal and the takeout come from the "I deserve this" bucket, where nobody counts. That's why the same person who balks at a $4 bag of spinach doesn't notice $30 a week in drinks.
Then there's present bias. In a classic 1998 experiment, Daniel Read and Barbara van Leeuwen found that people choosing a snack for next week leaned toward fruit, but people choosing in the moment, especially when hungry, reached for junk. We plan like healthy people and buy like hungry ones. The answer isn't more willpower at 3 p.m. It's deciding at the grocery store on Sunday, when you're fed and thinking clearly.
You can see the pattern everywhere. Americans spent about $105 billion on lottery tickets in 2024, according to Census data. People find money for the new phone, the streaming services and the game-day spread. That's not a criticism; it's proof. When something matters to us, we find the money. "It costs too much" usually means "it's not a priority yet."
To be fair, real barriers exist. Time is a cost. Cooking is a skill. Some neighborhoods have more drive-thrus than grocery stores. Those are reasons to make a plan, not reasons to quit, and every one of them is easier to solve than the health bill that comes from years of cheap calories.
How to Eat Well for Less, Starting This Week
Start with the drinks. Cutting sweetened beverages is the fastest, easiest money you'll ever save on food, and it removes a pile of empty sugar calories at the same time. Water costs you nothing.
Next, cook dinner at home five nights a week and make enough for tomorrow's lunch. One Sunday batch of rice, beans or chicken, and a sheet pan of vegetables covers most of the week. If you want ideas that still taste like home, read how to eat healthy in Hawaii without giving up plate lunch, and if you're over 50, make sure the plan covers how much protein you really need.
Plan your snacks before you're hungry: bananas, boiled eggs, a handful of nuts, yogurt. Our guide to what to eat before an evening workout has cheap options that keep the 3 p.m. crash away. Track one week of food spending, every receipt, and look at it honestly. The numbers will convince you faster than I can.

Frequently Asked Questions
- Is it really cheaper to eat healthy than to eat junk food?
- Per calorie, junk food is cheaper, and that is the only measure where the claim holds. Per portion actually eaten, USDA found grains, vegetables, fruit and dairy cost less than most snack and fast foods. And when researchers compared real spending, people who cooked at home most nights spent less per person than people who ate out often, while eating a better diet.
- What are the cheapest healthy foods to buy?
- Dried beans are the standout: USDA priced dried pinto beans at 23 cents per cup equivalent in 2023, the cheapest of 155 fruits and vegetables it tracked. Potatoes, onions, watermelon, apples, canned tomatoes, oats, rice, eggs and frozen vegetables are also consistently low-cost. Frozen and canned produce are just as nutritious as fresh for most uses.
- Why does healthy food seem more expensive at the store?
- Because people compare the wrong things: a $5 bag of salad against a $2 bag of chips, rather than the cost of a filling meal. Calorie-dense packaged food is cheap per calorie but leaves you hungry again in an hour. Price whole meals and weekly totals instead of single items, and the healthy cart usually wins.
- How can I eat healthy on a budget in Hawaii?
- Everything shipped to the islands costs more, chips and soda included, so the comparison still favors whole foods. Shop staples in bulk, lean on frozen vegetables, beans, rice, eggs and local produce in season, cook dinner at home most nights, and swap sweetened drinks for water. USDA's own budget plan shows a healthy Hawaii diet is achievable on a modest grocery budget.
