Processed foods are a daily part of modern life, but they’re often misunderstood.
Many people hear the word “processed” and immediately think “unhealthy,” but not all processed foods are created equal.
Here's what you should know to make smarter choices and understand what’s really on your plate.
Processed food is more than just junk
Food is considered processed if it's been altered in any way from its original state.

That includes simple actions like chopping, freezing, or cooking. So yes, even something as innocent as pre-washed salad mix counts as processed.
Food processing comes in different levels
There are different degrees of processing, from minimal to extreme.
The NOVA classification groups foods based on how much they’ve been altered and what has been added.
Group 1: Almost natural foods
Fresh berries, chopped veggies, and roasted nuts are Group 1 foods. They’ve only been slightly changed to make them easier to store or eat.

Group 2: Processed culinary ingredients
Butter, oil, sugar, and salt belong here. These are natural in origin but have been refined or pressed to make them easier to cook with.
Group 3: Foods with a few added ingredients
This includes canned fish, cheese, and fresh bread, items with added salt or oil that are ready to eat or use in other dishes.
Group 4: Ultra-processed food products
These are industrially produced items full of additives, flavor enhancers, and sweeteners. They barely resemble their original ingredients.
Some processing actually makes food healthier
Processes like pasteurization, fermentation, and freezing can extend shelf life, improve safety, or even boost nutrition in some cases. It’s not always a bad thing.

The supermarket is filled with ultra-processed choices
From breakfast cereal to microwave dinners, many products on the shelves fall into this highly processed category.
They’re designed to be convenient and tasty, but not always healthy.
Small snacks can be deceptively high in calories
It’s easy to underestimate how much you're consuming. Something that seems like a light treat may pack more calories than a whole serving of fresh vegetables.
Your body works harder to digest whole foods
Natural foods take more effort for your body to break down, which can help regulate appetite and metabolism.

Highly processed foods are digested faster, which may lead to overeating.
There may be a link between processed foods and cancer
Research has shown that diets high in ultra-processed foods may increase the risk of certain cancers.
This could be due to the additives, preservatives, or overall poor nutritional quality.
Processing removes natural nutrients
Many nutrients are lost during production.

While vitamins and minerals are often added back in later, the final product may still lack the full benefits of its original form.
Artificial ingredients change how food looks and tastes
Additives like flavor enhancers, colorings, and emulsifiers are often used to improve shelf life or appearance, but they may reduce the food’s nutritional value.
Processed foods are made to keep you eating
A carefully balanced mix of salt, sugar, and fat can make foods more appealing, and harder to stop eating. That’s by design, not coincidence.
Some processed foods can still be part of a healthy diet
Low-fat milk, whole-grain bread, and high-fiber cereals are examples of processed options that offer real nutritional value and can support a balanced diet.
Not all canned fruit is bad
Canned fruit stored in water or natural juice can be a convenient and healthy choice. Just avoid those packed in sugary syrups.
Reading labels makes a difference
Ingredient lists can be revealing. The fewer ingredients, and the more familiar they are, the better.
If most of the words sound like chemistry class, it’s probably best to skip it.
Fresh sections offer better choices
Stick to the fresh produce, meat, and dairy sections of the grocery store to find less processed, more wholesome options.
Unprocessed meats are usually healthier
Lean meats like chicken breasts or fish are typically better than processed alternatives like sausages, hot dogs, or bacon.
Home cooking gives you full control
When you make food from scratch, you know exactly what’s in it. That means fewer hidden sugars, less sodium, and better overall nutrition.
