Unprocessed foods are available at regular grocery stores, farmers markets, farm-direct programs, and online retailers. The key is knowing where to look in each setting and how to tell whether a product is truly unprocessed or just marketed that way. Unprocessed and minimally processed foods include fresh fruits, vegetables, whole grains, raw nuts, eggs, plain meat and fish, and dried legumes.
Your Regular Grocery Store
The simplest answer is the store you already shop at. Most of the unprocessed food in a supermarket sits along the outer perimeter: the produce section, the meat and seafood counter, the dairy coolers, and the bakery (for fresh bread with short ingredient lists). The center aisles are where ultra-processed products concentrate. That doesn’t mean you should skip them entirely. Dried beans, rice, oats, plain frozen fruits and vegetables, raw nuts, and cooking oils like olive oil all live in the center aisles and qualify as unprocessed or minimally processed.
The challenge is that many products in the center aisles look simple but aren’t. A practical way to check: scan the ingredient list for substances you wouldn’t use in a home kitchen. High-fructose corn syrup, hydrogenated oils, hydrolyzed proteins, and any of the “cosmetic” additives (flavors, flavor enhancers, emulsifiers, sweeteners, thickeners, colors, gelling agents) are markers of ultra-processing. If you see those, the product has moved well beyond minimally processed, regardless of what the front label says.
Plain yogurt, block cheese, butter, whole chicken, frozen shrimp, canned tomatoes (just tomatoes and salt), and bags of dried lentils are all examples of items you can grab during a normal shopping trip. You don’t need a specialty store to eat mostly unprocessed food.
Farmers Markets and CSA Programs
Farmers markets are one of the best sources for unprocessed food because nearly everything sold there is whole produce, eggs, raw honey, or fresh meat. The USDA maintains a free, searchable Local Food Directory that lists farmers markets across the country. You can filter by zip code, product type, payment method, and whether the market accepts SNAP benefits. The same directory covers CSA (community supported agriculture) programs, which deliver a box of locally grown produce on a regular schedule, usually weekly, in exchange for a seasonal membership fee.
CSAs are especially useful if you want to build meals around whatever is fresh that week. You pay upfront for a share of the harvest, and the farm sends you what’s ripe. This pushes you toward seasonal eating almost automatically, and the produce is typically harvested within a day or two of delivery. The tradeoff is less control over exactly what you get.
Buying Meat and Dairy Directly From Farms
For unprocessed meat, buying directly from a ranch or farm gives you the most transparency about how the animal was raised. Many states have local beef directories (Iowa’s and the Northeast’s are well-known examples) where farms list their products for direct sale. You can often buy a quarter, half, or whole animal and have it butchered to your specifications, which brings the per-pound cost well below retail for comparable quality.
Small dairy farms in states that permit raw milk sales also sell directly to consumers, along with farm-made butter, cream, and fresh cheese. For anything you can’t source locally, online platforms like ButcherBox, US Wellness Meats, and similar services ship frozen, minimally processed cuts nationwide. Just verify that the products aren’t pre-marinated or injected with solutions, which adds processing.
Online Bulk and Specialty Retailers
If you’re looking for whole grains, dried legumes, raw nuts, seeds, and spices in larger quantities, online bulk retailers are often the most cost-effective option. Sites like Azure Standard, Thrive Market, and even Amazon’s grocery section carry 25-pound bags of dried beans, whole wheat berries, steel-cut oats, and similar staples. Buying in bulk makes sense for shelf-stable unprocessed foods because they last a long time. Dried rice and pasta keep for about two years in a cool, dry place. Whole grains in airtight containers last similarly.
For people who want to take whole grains a step further, home flour mills let you grind wheat berries, rye, or spelt into fresh flour on demand. According to researchers at the Tufts Food Lab, freshly milled whole grain flour offers the best nutrient profile because the vitamins and oils in the grain haven’t had time to degrade on a shelf. Home mills range from about $100 to $350 or more, and some work as attachments for a stand mixer you may already own.
Shopping Seasonally to Save Money
One common concern about unprocessed food is cost. A meta-analysis published in BMJ Open found that the healthiest dietary patterns cost about $1.50 more per day (roughly $550 per year) than the least healthy ones when standardized to 2,000 calories. That gap is real but smaller than many people assume, and it varies by food group. Healthier protein sources showed the biggest price difference at about $0.29 more per serving, while grains differed by only $0.03 per serving. Healthier dairy options were actually slightly cheaper.
Seasonal shopping is one of the most effective ways to close that gap. Fruits and vegetables cost less and taste better when they’re in peak season locally. The USDA’s Seasonal Produce Guide breaks availability down by season: summer brings the widest variety (berries, stone fruit, corn, tomatoes, zucchini, melons), while winter narrows the field to hardy options like root vegetables, citrus, cabbage, kale, and winter squash. Buying what’s abundant right now, rather than what was shipped from another hemisphere, consistently saves money.
Frozen fruits and vegetables are another budget-friendly option that counts as minimally processed. They’re typically flash-frozen at peak ripeness with no added ingredients, and they’re available year-round at a fraction of the cost of out-of-season fresh produce.
How to Spot Hidden Processing
Not everything marketed as “natural,” “whole,” or “simple” is actually unprocessed. Granola bars, flavored yogurts, veggie chips, and many packaged smoothies contain additives that place them firmly in the ultra-processed category. The ingredient list is your only reliable tool.
Look for these red flags:
- Substances rarely used in home cooking: high-fructose corn syrup, hydrogenated or interesterified oils, hydrolyzed proteins, maltodextrin, invert sugar
- Cosmetic additives: anything listed as a “flavor” or “natural flavor,” color additives, emulsifiers (like soy lecithin in products where it isn’t needed), thickeners (like carrageenan or xanthan gum), and sweeteners (like sucralose or acesulfame potassium)
A truly unprocessed or minimally processed food either has no ingredient list (an apple, a chicken breast) or a very short one where every item is a recognizable whole food. Canned black beans with water, beans, and salt? Minimally processed. Canned “bean soup” with modified food starch, natural flavors, and disodium inosinate? That’s ultra-processed.
Storing Unprocessed Foods at Home
Because unprocessed foods lack the preservatives that extend shelf life in packaged products, storage matters more. Fresh produce lasts anywhere from a few days (berries, leafy greens) to several weeks (root vegetables, apples, citrus) when refrigerated properly. Whole grains and dried legumes are the workhorses of an unprocessed pantry: stored in a cool, dry spot below 85°F, they keep for up to two years. Raw nuts and seeds last longest in the freezer, where their natural oils won’t go rancid.
Fresh meat and fish should be cooked or frozen within a couple of days of purchase. If you’re buying in bulk from a farm, most of it will come frozen already, which gives you months of flexibility. The biggest adjustment when shifting to unprocessed food isn’t finding it. It’s planning around shorter shelf lives and cooking more from scratch, which gets easier once your pantry is stocked with the dry staples that last.
