Canned Food Myths
The aordability of canned foods entices
many people to stock up on the essentials.
However, there are some people who still
harbor concerns about the safety of canned
foods. Getting to the truth about canned
foods can assuage some of those concerns
and help those on the fence stock up on
these budget-friendly staples.
Myth #1: Canned foods are not as healthy as fresh foods.
Fresh foods, once harvested, have a nite shelf life. Plus, once fruit or vegetables are picked, their vitamin
and mineral content decreases each day that they are not consumed. Many canned foods are picked and
processed on the same day, helping to retain nutrients at their peak and lock them in for many months.
Also, according to the Hy-Vee supermarket chain, sometimes canned foods are packed with additional
nutrients, such as increased lycopene in canned tomatoes.
Myth #2: Canned foods are full of preservatives.
The perception that canned foods are “processed” foods often leads people to believe they’re full of unsavory
ingredients. The term processing is used to describe any food that has been changed from its natural form. So
removing corn from a cob counts as processing, as is baking or boiling potatoes. Canned foods are preserved
by heating the items and sealing them under pressure. No other preservatives are needed to keep them fresh.
Myth #3: Can linings are dangerous.
There has been controversy concerning BPA-containing plastics for many years. Even though the Food
and Drug Administration, as well as other international food safety agencies, has evaluated the extensive
body of science and continue to arm BPA’s safety in food packaging, some manufacturers are voluntarily
moving away from it. Consumers can nd many foods packed in cans with non-BPA linings. However,
even foods packaged in BPA are considered safe for consumption.
Myth #4: Canned foods are full of sodium.
Some canned foods will contain salt as an added ingredient to improve taste and act as a freshness
preservative. But canned foods do not rank among the biggest oenders in regard to excessive amounts
of sodium. In 2012, the Centers for Disease Control and Prevention released a study that identied the
top 10 food categories that contribute to high sodium diets. Pizza, cured meats, cold cuts, and rolls made
the list, while canned foods did not.
Myth #5: Canned foods do not taste good.
Because foods are canned when they are at peak freshness and ripeness after harvest, they retain full avor
if properly stored.
Myth #6: All dented cans are unsafe.
Cans can become dented in transit. Drop a can and it will dent. But that doesn’t necessarily mean foods
inside dented cans are unsafe to eat. If a can is bulging or if the top or bottom of the can moves or makes a
popping sound, the seal has probably been broken or compromised by bacteria and should be thrown out.
Canned foods are safe and can make for valuable additions to any pantry.
