Canned sardines have been a staple in many cuisines around the world for centuries. These small, oily fish are packed with nutrients and are often considered a healthy addition to a balanced diet. However, with the growing awareness of processed foods and their potential health risks, many people are left wondering: are canned sardines considered processed food?
What Constitutes Processed Food?
Before we dive into the world of canned sardines, it’s essential to understand what constitutes processed food. The term “processed food” refers to any food that has been altered from its natural state through various methods, such as canning, freezing, dehydrating, or adding preservatives. These methods can enhance the food’s shelf life, texture, and flavor, but they can also lead to a loss of nutrients and an increase in unhealthy additives.
The degree of processing can vary greatly, and foods can be classified into different categories based on their level of processing. The NOVA classification system, developed by researchers at the University of Sydney, categorizes foods into four groups:
- Unprocessed or minimally processed foods: These are whole foods that have not been altered from their natural state, such as fruits, vegetables, and whole grains.
- Processed culinary ingredients: These are foods that have been altered through various methods, such as canning, freezing, or dehydrating, but are still recognizable as whole foods, such as canned beans or frozen vegetables.
- Processed foods: These are foods that have been significantly altered from their natural state and often contain added preservatives, flavor enhancers, or other unhealthy additives, such as packaged snack foods or sugary drinks.
- Ultra-processed foods: These are foods that have been highly processed and often contain a cocktail of unhealthy additives, such as artificial sweeteners, flavor enhancers, and preservatives, such as frozen pizzas or energy bars.
The Canning Process: How Sardines Go from Fresh to Canned
So, where do canned sardines fit into this classification system? To answer this question, let’s take a closer look at the canning process.
Canned sardines are made from fresh sardines that are caught, cleaned, and then processed through various stages:
Step 1: Catching and Cleaning
Fresh sardines are caught from the ocean and immediately cleaned and gutted to remove any impurities.
Step 2: Sorting and Grading
The sardines are then sorted and graded according to their size and quality.
Step 3: Canning
The sardines are packed into cans, which are then filled with a liquid, such as water, oil, or sauce.
Step 4: Heat Processing
The cans are then heated to a high temperature to kill off any bacteria and extend the shelf life of the sardines.
Step 5: Packaging and Distribution
The cans are then packaged and distributed to stores, where they can be purchased by consumers.
Are Canned Sardines Considered Processed Food?
Based on the NOVA classification system, canned sardines would fall into the category of processed culinary ingredients. While they have been altered from their natural state through the canning process, they are still recognizable as whole foods and do not contain any added preservatives or unhealthy additives.
However, it’s essential to note that not all canned sardines are created equal. Some brands may add extra salt, sugar, or other ingredients to enhance the flavor or texture of the sardines. These added ingredients can increase the processing level of the sardines and make them less healthy.

What are canned sardines and how are they made?
Canned sardines are small, oily fish that are typically caught, processed, and packed in airtight containers to preserve them for later consumption. The process of making canned sardines involves several steps, including cleaning, sorting, and packing the fish into cans, which are then sealed and heated to kill off any bacteria and extend the shelf life of the product.
The canning process itself is a form of preservation that allows the sardines to be stored for long periods of time without refrigeration. The fish are usually packed in a liquid, such as water or oil, which helps to keep them moist and flavorful. Some canned sardines may also contain added salt or other seasonings to enhance their flavor.
Are canned sardines considered a processed food?
Yes, canned sardines are considered a processed food. While they are made from a natural ingredient (the sardine fish), the canning process involves several steps that alter the food from its natural state. The fish are cleaned, sorted, and packed into cans, and the canning process itself involves heating the fish to high temperatures to kill off bacteria and extend shelf life.
However, it’s worth noting that not all processed foods are created equal. Canned sardines are generally considered a minimally processed food, meaning that they have undergone fewer changes from their natural state compared to other processed foods. Additionally, canned sardines are often lower in added preservatives and other unwanted ingredients compared to other processed foods.
