Are canned fruits and vegetables good for you?

Eating fruits and vegetables is an important part of a healthy diet. Fresh produce provides essential vitamins, minerals, fiber and antioxidants. However, fresh produce can be inconvenient, expensive and spoil quickly. For these reasons, many people rely on canned fruits and vegetables as an alternative. But are canned produce as nutritious as fresh?

The Pros of Canned Fruits and Vegetables

Canned fruits and vegetables offer several advantages over fresh:

  • Convenience – Canned produce is pre-washed, peeled, cut and ready to eat. This saves time spent preparing fresh produce.
  • Long shelf life – Canned produce can be stored for 1-2 years compared to only a few days for fresh.
  • Availability – Canned produce is available year round, while fresh varies by season.
  • Affordability – Canned produce is typically cheaper than fresh.
  • Food safety – The canning process kills bacteria and other pathogens, so canned produce is safe to eat without further cooking.

Nutrient Comparison of Fresh vs. Canned

Although canned produce is very convenient, there are some differences in nutrient content compared to fresh. Here is how the nutrient content of common canned fruits and vegetables compares to their fresh counterparts:

Produce Nutrient Fresh Canned
Peaches Vitamin C 10 mg 4 mg
Green beans Fiber 2.7 g 2.2 g
Sweet corn Folate 23 mcg 11 mcg
Carrots Vitamin A 210 mcg 110 mcg

As shown, levels of water-soluble vitamins like vitamin C and folate tend to be lower in canned produce compared to fresh. This is due to leaching into the canning liquid. However, canned produce still retains a good amount of these nutrients.

Levels of fat-soluble vitamins like vitamin A are better retained during the canning process. Canned produce may also contain comparable or even higher levels of certain minerals like iron and calcium versus fresh.

Tips for Getting the Most Nutrition from Canned Produce

Here are some tips to get the most nutritional value from canned fruits and vegetables:

  • Look for canned options with no added salt or sugar.
  • Rinse canned produce under running water to remove some sodium.
  • Opt for fruit canned in 100% juice rather than heavy syrup.
  • Choose vegetables with lower sodium like beans, tomatoes and mixed vegetables.
  • Include the liquid from vegetables to get back some water-soluble vitamins.
  • Enjoy a variety of different canned produce to get a mix of nutrients.

Potential Downsides of Canned Produce

Although canned produce offers many benefits, there are a few potential downsides to consider:

  • Higher sodium – Canning vegetables requires adding sodium to help stabilize texture and color. Canned veggies can contain over 10 times more sodium than fresh.
  • Presence of BPA – Some cans are lined with BPA plastic sealant, which may leach trace amounts of this potentially harmful chemical.
  • Higher price – Ounce for ounce, canned produce is often more expensive than fresh.
  • Textural changes – The high heat of canning alters the texture of produce, making it softer.
  • Loss of flavor – Some subtle flavors and aromas may degrade during prolonged high heat canning.

Canned vs. Frozen vs. Fresh

How do canned fruits and vegetables compare to frozen and fresh? Here is a quick comparison:

Form Pros Cons
  • Highest nutrients
  • Best taste and texture
  • Short shelf life
  • More prep work
  • Higher cost
  • Retains nutrients well
  • Easy to use
  • Lower cost than fresh
  • Requires freezer space
  • Can lose texture when thawed
  • Low cost
  • Long shelf stable
  • Provides some nutrients
  • Higher sodium
  • Lower nutrients than fresh
  • Softer texture

Each form has pros and cons. For maximum nutrients and taste, fresh is best. But frozen and canned offer more convenience at a lower cost.

The Bottom Line

Canned fruits and vegetables can be a nutritious pantry staple when fresh produce is unavailable. While fresh is highest in nutrients, canned produce retains a significant amount of vitamins, minerals and antioxidants after processing. Rinsing sodium and choosing options with no added sugar or salt enhances the nutrition of canned produce.

While moderate use is fine, variety is still important. Rotate use of fresh, frozen and canned produce for the best mix of convenience, affordability and nutrition in your diet.
