If you’ve been keeping up with wellness trends, you’ve probably seen a lot of talk about processed foods and how harmful they can be. It’s true that a diet high in processed foods can lead to overeating. These foods often pack in extra salt, sugar, and additives, which aren’t great for your health.
However, not all processed foods are bad. It’s important to understand the different types and what to look for on labels when you’re shopping.
Researchers use the Nova classification system to break down foods into four categories:
Group 1: These are unprocessed or minimally processed foods. Think fresh vegetables, fruits, fish, and whole grains. They’re basically the foods you can eat as they are or with minor prep.
Group 2: These include culinary ingredients from Group 1, like oils and sugars. They’re used to enhance flavors in cooking.
Group 3: This category contains processed foods that have been preserved using traditional methods. Examples are canned vegetables and whole-grain breads. You could easily make these at home.
Group 4: These are ultra-processed foods made in factories, packed with additives, and often very tasty but lacking in nutritional value. Items like sugary cereals, frozen meals, and packaged snacks fall into this category.
The big concern with ultra-processed foods is how much of them people consume. In Australia, around 42% of total energy comes from these foods. They can be cheap and calorie-dense but often provide little nutrition—just empty calories.
Recent studies show that higher consumption is linked to poorer health outcomes. For instance, people who eat more ultra-processed foods have a 25% greater chance of kidney function decline and a higher risk of obesity, diabetes, and mental health issues like depression, according to a review of 122 studies.
Interestingly, not all ultra-processed foods are equal. Some products, like breakfast cereals with added nutrients, can be beneficial, while sugary drinks are often harmful. This complexity leads researchers to suggest careful monitoring of what we consume.
It’s worth noting that some processing can actually be good. For example, certain additives can enhance food safety and shelf life. The use of these food additives is regulated by Food Standards Australia and New Zealand (FSANZ) to ensure safety.
However, many people, including children, consume a lot of ultra-processed foods, which can lead to high levels of additives in their diets. Researchers have called for better public health messages regarding these foods. Concerns are being raised about how combinations of additives might increase health risks, particularly in conditions like type 2 diabetes, as highlighted in a study involving over 100,000 French adults found.
So, how do you choose processed foods wisely? Here are some pointers:
- Check the ingredient list. Fewer additives and recognizable ingredients are better.
- Look for products with higher Health Star Ratings. These indicate cleaner options.
- Consider how often you eat certain items. If they’re a regular part of your diet, take extra time to compare choices.
Remember, just because a food falls into Group 3 doesn’t guarantee it’s healthy. Some might still have high levels of salt, fat, or sugar. For more detailed insights, consider using an app like Open Food Facts to help assess food processing levels and nutritional content.
