Some say that canned foods should be part of a balanced diet. This article describes what you need to know precisely about canned food. 

What is Canned Food?

Canning is a long-term process of food preservation by sealing it in sealed containers. Canning was first established at the end of the 18th century as a method to ensure a reliable supply of food for soldiers and sailors at the battle. The canning phase can differ slightly depending on the product, however, there are three key steps. These include the following: 

It’s processing. The food is sliced, diced, minced, bruised, boned, minced, or fried. 

  • Sealing. The food stored is packed in containers. 
  • It’s heating. Cans are warmed to destroy bacteria and to avoid oxidation
  • It helps food to be healthy and safe to consume for 1–5 years or longer. Popular packaged foods include fruit, vegetables, beans, soups, meat, and seafood.

It can include trace quantities of BPA 

BPA (bisphenol-A) is a compound that is sometimes used in packaged foods, including containers. Research shows that BPA in canned food can move from the can liner to the food it contains. One study studied 78 packaged food and found BPA in more than 90% of them.  In fact, a study has shown that consuming processed food is a primary cause of BPA  disclosure. In one research, participants who ate 1 serving of canned soup daily for 5 days reported more than 1,000 percent rise in BPA levels in their urine. While data is conflicting, some human researchers have associated BPA to health conditions such as heart disease, type 2 diabetes, and men’s sexual arousal.

It can contain harmful bacteria 

While it is relatively rare, canned foods that have not been prepared properly may include harmful bacteria known as Clostridium botulinum. Eating canned food can trigger botulism, a chronic disease that can lead to disability and death if remain unattended. Many cases of botulism originate from products that have not been prepared properly at home. Botulism from professionally canned foods is uncommon. It is essential that you never eat from containers that are billowing, wrecked, broken, or leaky.

Involve salt, sugar or added preservatives

 Salt, sugar, and additives can be applied during preparation and handling. Many canned foods can be high in sodium. Although this does not represent a health threat to most people, it may be troublesome for others, as well as those with hypertension. These can also include refined sugar, which may have adverse effects. Added glucose has been associated with a significantly increased risk of many illnesses, such as obesity, heart disease, and type 2 diabetes. A range of other synthetic or natural additives can also be included.


This is appropriate, however, if you eat the packaged food under regulation. Please don’t over-consume canned food as it could endanger you. Just take the prescribed amount of nutrients and don’t rely on canned food to live (unless it becomes everything you have). Strictly speaking, aim to keep yourself safe by buying new or organic food online or at your local supermarket.
