Canned, frozen, and packaged foods can deliver the same core nutrients as fresh produce at a fraction of the cost, according to nutrition guidance published by Self, which outlined seven strategies for building a healthy diet around shelf-stable groceries as food prices remain elevated.
The central obstacle is cost. "Groceries are a fortune," the source noted, a reality that has pushed shoppers toward cheaper, longer-lasting alternatives. Frozen and canned goods typically carry lower price tags than their fresh counterparts and stay usable for months, reducing the waste that erodes grocery budgets when fresh items spoil before they are eaten.
Dietitians point to shelf life as a practical advantage, not just a financial one. "You can keep them in your freezer for months, so that often gives people confidence," the source quoted, describing how longer storage windows let households buy in bulk and plan meals further ahead.
The most common barrier is the belief that processed means unhealthy. One nutrition professional called that "a big, big misconception," noting that freezing and canning preserve vitamins and minerals at harvest rather than stripping them out. Frozen produce is typically blanched and flash-frozen within hours of picking, which locks in nutrient content that fresh vegetables can lose during days of shipping and storage.
Sodium is the variable that matters most. Many brands now sell low-sodium or no-salt-added versions of canned beans, vegetables, and soups, and choosing those options keeps sodium intake in check without eliminating the convenience. Rinsing canned beans and vegetables under running water removes a meaningful share of the surface sodium before the food ever reaches a plate.
Packaged goods reward label reading. Comparing nutrition panels across brands for added sugar, saturated fat, and sodium lets shoppers separate products that carry real nutritional value from those that mostly deliver calories. Whole-grain packaged options, plain frozen vegetables without sauce, and canned fish packed in water are among the categories where the nutritional profile holds up well.
The guidance arrives as households continue adjusting to grocery costs that have climbed faster than overall inflation in recent years. The Bureau of Labor Statistics reported that food-at-home prices rose sharply through 2022 and 2023 before moderating, leaving many families searching for ways to stretch weekly budgets.
Building meals around a mix of fresh, frozen, and canned ingredients also hedges against supply disruptions and seasonal price swings. When fresh produce costs spike out of season, frozen and canned alternatives typically hold steadier prices, giving shoppers a consistent base for planning meals regardless of what the fresh aisle looks like that week.
