What are ultra-processed foods?
Ultra-processed foods (UPFs) are industrial formulations of ingredients, often containing little or no whole foods. They are created using a series of industrial techniques and typically contain additives, preservatives, artificial flavors, and sweeteners not found in a home kitchen. The NOVA classification system categorizes foods into four groups based on the level of processing, with UPFs in the highest tier. Examples include soft drinks, sugary cereals, packaged snacks like chips and cookies, processed meats, and ready-to-eat meals. Even some products marketed as healthy, like certain protein bars or plant-based meat substitutes, can be ultra-processed due to their ingredients and manufacturing methods.
The health implications of frequent consumption
Regularly consuming a diet high in ultra-processed foods is associated with a wide range of adverse health outcomes. A high intake can increase the risk of obesity, cardiovascular diseases, certain cancers, and type 2 diabetes. Studies show an association between UPF consumption and mental health issues like depression and anxiety. The health impact is multifaceted, stemming not only from their high levels of added sugar, saturated fat, and sodium but also potentially from the processing itself and the presence of additives. The manufacturing processes can alter food structure, potentially affecting digestion, satiety, and gut microbiome health. These combined factors lead to a higher daily energy intake and lower nutrient density compared to whole-food diets.
How often can I eat ultra-processed food? The balancing act
There is no universally prescribed number for how often one can safely eat ultra-processed foods. Experts agree that occasional consumption is not the primary concern; rather, it is when these foods become a regular staple that the risks increase. Many health professionals suggest a guideline that focuses on overall dietary quality, such as an 85/15 rule, where 85% of your diet consists of nutrient-dense, minimally processed foods. The occasional treat is fine, but daily reliance on UPFs is problematic. One study found that people consuming an average of seven servings of ultra-processed food per day had a higher risk of adverse health outcomes than those with an average of three servings. The goal is to minimize, not necessarily eliminate, and to shift your dietary pattern towards more whole foods.
Practical guidelines for frequency
- Prioritize whole foods: Build your meals around unprocessed or minimally processed ingredients, such as fresh fruits, vegetables, whole grains, and lean proteins. By focusing on these foods, there will be naturally less room for UPFs.
- Make UPFs an occasional treat: Reserve your favorite ultra-processed snacks and desserts for infrequent, special occasions rather than daily habits. This helps to reframe them as indulgences rather than dietary staples.
- Focus on balance, not perfection: Instead of striving for a 100% UPF-free diet, which is unrealistic for many, aim for a sustainable pattern of reduction. Even small, consistent changes make a difference over time.
Making healthy swaps for ultra-processed foods
Making deliberate swaps can dramatically reduce your overall UPF intake. Here is a comparison of common ultra-processed items and their healthier counterparts:
| Ultra-Processed Food | Healthier Swap | Benefits of Swap |
|---|---|---|
| Sugary breakfast cereal | Porridge with fruit and nuts | Higher fiber, lower added sugar, better satiety |
| Packaged cookies/biscuits | Handful of nuts, seeds, or fresh fruit | More fiber, healthy fats, vitamins, and minerals |
| Flavored yogurt | Plain yogurt with fresh fruit or honey | Eliminates artificial sweeteners and high sugar content |
| Instant noodles | Whole-grain pasta with homemade tomato sauce | Higher fiber, lower sodium, better nutrient profile |
| Packaged ham/sausages | Cooked chicken, tuna, or homemade meatballs | Lower in nitrates, salt, and processed additives |
| Soda/Sweetened beverages | Water infused with lemon/cucumber or plain seltzer | Zero added sugar, better hydration |
Strategies to reduce ultra-processed food intake
Reducing your intake of ultra-processed foods is a process, not an overnight change. Starting with small, manageable steps can lead to lasting habits.
Start slowly: Pick one or two ultra-processed items you frequently consume and find a healthy swap for them. Once that change feels natural, tackle another item. This gradual approach is more sustainable than a complete, immediate overhaul.
Cook more at home: Home cooking gives you complete control over the ingredients. Batch cooking and meal prepping can save time on busy days, making it easier to resist convenient but less healthy UPF options. For recipe ideas and inspiration, exploring resources from reputable sources like the British Heart Foundation can be helpful.

Read and understand labels: Many processed foods have long ingredient lists with unfamiliar names. Look for shorter lists with ingredients you recognize. Check the nutritional information for high levels of added sugar, sodium, and saturated fat. This builds awareness and helps in making informed choices.
Plan your snacks: Have healthy, portable snacks readily available to avoid impulsive UPF purchases. Items like nuts, seeds, fruit, or pre-cut vegetables with hummus can satisfy cravings nutritiously.
Stay hydrated with water: Swapping sugary drinks for water or unsweetened alternatives is one of the most impactful changes you can make to reduce UPF intake.
Conclusion: Progress over perfection
While the science linking high ultra-processed food consumption to health issues is compelling, the occasional treat or convenience item is unlikely to have a major impact within an otherwise balanced, whole-food-rich diet. The key is to reduce overall reliance on these products by making mindful, gradual changes. By focusing on whole foods, cooking at home more often, and learning to identify UPFs, you can significantly improve your dietary quality and long-term health. Remember, it's about making steady progress toward a healthier eating pattern, not achieving a perfect, unattainable diet overnight.
