Eating More Plants Can Help Your Grocery Budget

Is Plant-based food more expensive?

My grocery bill is cheaper than some of my friends’. They complain about the cost of eggs and beef, but I haven’t bought either of those foods for years. I eat a whole food plant-based diet. People think my grocery bill is higher than the standard American diet. It’s a myth. According to a 2025 poll by the Physicians Committee for Responsible Medicine, many adults believe plant-based diets cost more than animal-based ways of eating even though this perception often doesn’t match reality.

I can testify that eating plants helps my budget. Last week I made mushroom meatballs with mushrooms I bought at Costco. I paid $3.99 for a big 24-ounce container of mushrooms, (about $2.66 per pound). At Walmart, the cheapest ground beef was $5.50 per pound for a 4.5lb tray. If I had made the meatballs out of ground beef, I would have paid $2.84 per pound more.

What is whole food-plant-based vs animal based?

Examples of foods in a whole food plant-based diet

Whole food plant-based foods include beans, lentils, peas, whole grains, potatoes, vegetables, fruits, nuts and seeds. It does NOT include expensive plant-based meats and specialty vegan products that can drive costs up. Animal-based foods include meat, deli meat, cheese, dairy, eggs, and processed convenience foods.

What the research says

There is substantial research on the topic of plant-based food prices vs animal-based food prices. According to a 2026 study published in a nutrition journal, whole food plant-based diets were generally less expensive than the standard omnivore diets in many countries. The review synthesized global evidence from 2000 to 2025 and found that affordability varies by income level and how much people rely on processed plant-based alternatives. Focusing on staple plant foods keeps costs lowest.

Research published in JAMA Network Open found that participants who switched to a vegan diet reduced their daily food costs by about $1.80, a 19% decrease from their regular eating habits. The biggest savings came from cutting out meat (nearly $2.90 per day), dairy ($0.50), and added fats ($0.50). While spending on vegetables, grains, and plant-based alternatives did increase slightly, those costs were more than offset by the reductions elsewhere. Over a year, that adds up to more than $650 in savings compare to a standard American eating pattern.

Meat and dairy prices are only going one direction

Meat prices are increasing

While it is true that the cost of food is increasing in general, it is increasing more for animal products than for whole food plant-based food. According to Pew Research data, the cost of meat, poultry, fish and eggs has seen the fastest inflation of any food category since January 2020, with prices up 36.4%. USDA Economic Research Service data shows the price of ground beef, once the budget-friendly staple of American cooking, is up more than 51% since February 2020.

Meanwhile, dried lentils, canned beans, oats, and rice have remained some of the most inflation-resistant foods in the grocery store. In 2026, tofu averages $2.75 to $3.50 per pound, compared to $4.50 to $6.00 for chicken breast and $6.50 to $9.00 for ground beef. A household of four that swaps meat for tofu just three times per week could save over $400 per year on protein alone.

Your grocery budget vs your medical bills

You can get all the nutrition you need without animal products. Switching to plant-based eating is like a long-term investment in your health. Whole food plant-based diets are associated with lower risk of cardiovascular disease and lower overall mortality. Fewer chronic conditions mean fewer medications, fewer copays, and less time off work for illness. Those are real costs most of us care about even if we don’t calculate them daily.

Canned beans	½ cup drained	$0.25–$0.40	~7–8 g	~$0.35–$0.55	High fiber, very convenient, low fat
Lentils (cooked)	½ cup cooked	~$0.15–$0.25	~9 g	~$0.20–$0.30	High fiber, folate, iron, no cholesterol
Firm tofu	3 oz (about 85 g)	~$0.50–$0.75	~9–10 g	~$0.50–$0.80	Iron, some calcium, low saturated fat
Ground beef (80% lean)	3 oz cooked	~$1.20–$2.00+	~21–23 g	~$0.60–$0.90+	Heme iron, B12, higher saturated fat, no fiber
Chicken breast	3 oz cooked	~$0.90–$1.50+	~21 g	~$0.45–$0.70+	Lean protein, no fiber, some B vitamins
Egg	1 large	~$0.20–$0.30	~6 g	~$0.35–$0.50	B12, choline, no fiber

Five practical ways to save money on a plant-based diet

Save money

Buy dry beans and lentils

Dry beans and lentils have a long shelf life. They are some of the most economical sources of protein. You can stock up when they are on sale to keep them on hand. It is easy to prep meals with dry beans and lentils because you can cook them ahead of time and use them across multiple meals.

Build meals around staples

Staple plant-based foods can be used in many ways for multiple meals. For example: rice and beans, lentil soup, oatmeal bowls, and baked potatoes can be used as side-dishes, soups, or the main course.

Use frozen produce

Frozen produce can be cheaper than fresh. Frozen produce is picked at the peak ripeness, so you don’t have to worry about whether it is ready to eat. You waste less because you only use what you need and keep the rest frozen. Frozen produce can be available year-round.

Shop seasonal produce

Find seasonal produce for your location, for example: Summer berries, Fall squash, Winter cabbage, and Spring greens. If there is a local farmer’s market, it is even better because it costs less to ship and distribute. Another way to eat seasonal produce is to grow your own fruits and vegetables. Start with a few potted plants.

Reduce food waste

Plant-based foods are useful for clearing leftovers creatively. Many parts of plants can be cooked down into vegetable stock. You can blend fruit and veggies into dressings, sauces and smoothies. Freeze extras for easy future meals.

Conclusion

Many affordable foods are some of the most nutritious. Plant-based foods like beans, lentils, grains, and vegetables are the foundation of one of the healthiest ways to eat. Even small shifts in this direction tend to pay off for your health and wallet.
