Defining Processed Food: A Matter of Degree
To understand if are meal kits processed food, it's crucial to first define what 'processed' means. The term is not a simple binary, but rather exists on a spectrum. The USDA broadly defines any food that has undergone changes from its natural state—including washing, chopping, freezing, or cooking—as processed. By this definition, all meal kits contain processed food, as their ingredients are at least minimally processed before packaging.
However, a more useful framework is the NOVA classification system, which differentiates between four levels of processing.
Levels of food processing
- Group 1: Unprocessed or minimally processed foods. These are whole foods like fresh vegetables, fruits, and lean meats. Minimal processing includes freezing, drying, or pasteurization. Many meal kits rely heavily on these ingredients.
- Group 2: Processed culinary ingredients. These are substances like oils, sugar, and salt, which are extracted from Group 1 foods. Meal kits often require you to add these to your home-cooked meal.
- Group 3: Processed foods. This group combines items from Groups 1 and 2 and includes simple products like canned vegetables, cheese, or freshly made bread.
- Group 4: Ultra-processed foods (UPFs). These are industrial formulations made mostly from substances derived from foods, with numerous additives, emulsifiers, flavorings, and preservatives. They are engineered for convenience and shelf-stability. Classic examples include sugary drinks, packaged cookies, and fast food.
Most traditional meal kits fall within the minimally to moderately processed categories, relying on fresh produce and meats. The extent to which they cross into the 'ultra-processed' category depends on the company and the specific recipe's ingredients.
The Role of Meal Kit Components in Processing
The level of processing in a meal kit is not uniform. It depends entirely on the components provided. For traditional kits where you do most of the cooking, you have more control over the final product.
How meal kits use processing
- Minimal Processing: Most meal kits provide fresh, pre-portioned vegetables, meats, and grains. These ingredients are minimally processed, involving only chopping, measuring, and packaging for freshness.
- Moderate Processing: Kits may include moderately processed items like canned beans or tomato sauce, or freshly made, simple sauces. These are generally not ultra-processed unless they contain many industrial additives.
- Higher Processing: Some kits include pre-made sauces, marinades, or seasoning packets that contain preservatives, artificial flavors, and added sugars or sodium. These are the components that push the meal towards the ultra-processed end of the spectrum.
- Ready-to-eat meals: Some services offer pre-cooked, 'heat-and-eat' meals, which are a different category from traditional meal kits. These are often a more reliable source of ultra-processed food, with specific examples like Factor Meals being flagged for having numerous additives.
Comparison: Traditional Meal Kits vs. Highly Processed Meals
| Feature | Traditional Meal Kits | Highly Processed/Ready-to-Eat Meals | Fast Food | Whole-Food Cooking |
|---|---|---|---|---|
| Processing Level | Minimal to Moderate | High to Ultra-Processed | High to Ultra-Processed | Minimal or None |
| Key Components | Fresh, raw ingredients; some prepared sauces | Pre-cooked components; sauces with additives | Highly formulated, reconstituted ingredients | Whole, fresh, or minimally altered foods |
| Ingredient Transparency | High; you can read the list and see the ingredients | Lower; complex ingredient lists with additives | Very low; often opaque with complex additives | High; you control every ingredient |
| Sodium Content | Variable; often can be controlled by adding less seasoning | Often very high due to preservatives | Often very high | Controlled by the cook |
| Additives | May contain some in pre-made sauces or seasoning | Contains numerous preservatives, emulsifiers, and flavorings | Contains numerous additives for preservation and flavor | None |
| Nutrient Retention | High, since most cooking happens at home | Lower, due to extensive industrial processing | Lower | High, as nutrients are preserved in whole foods |
How to Choose the Healthiest Meal Kit
Making informed choices can help you reap the convenience benefits of meal kits without compromising on a healthy diet. It's all about being a savvy consumer.
Tips for selecting healthy meal kits
- Read the ingredient lists. Check for the ingredients in sauces, marinades, and seasonings. If you see many unfamiliar names or a long list of additives, the meal is more processed.
- Focus on fresh ingredients. Look for services that emphasize and deliver primarily fresh, whole ingredients.
- Opt for simple recipes. Choose meals that require more hands-on cooking. Fewer pre-made components often mean less processing. Look for kits that provide just the fresh ingredients and a recipe, not pre-prepared sauces.
- Select low-sodium or 'clean' options. Many companies offer menu filters for dietary needs, including low-sodium or heart-healthy meals. Some services focus on using unrefined ingredients.
- Be cautious with ready-to-eat meals. If convenience is your priority, choose services specializing in fresh, whole-food-based ready meals, not those with complex, industrial ingredient lists.
- Customize your kits. If your kit includes a higher-sodium sauce, consider making your own simple version at home using fresh ingredients and less salt.
Conclusion: Navigating the Processing Spectrum
So, are meal kits processed food? The answer is yes, to some extent, but the critical distinction lies between minimal processing and ultra-processing. While meal kits inherently involve some level of processing (packaging, chopping), they are not inherently ultra-processed like fast food or sugary snacks. The key is to examine the specific components of each meal. By focusing on kits that provide mostly fresh, whole ingredients and simple recipes, you can enjoy the convenience of meal delivery while maintaining control over your nutritional intake. Ultimately, meal kits can be a tool to support healthier eating habits, provided you choose wisely and remain aware of what's in your food.

Keypoints
- Processing Varies: Meal kits range from minimally processed (freshly chopped ingredients) to including moderately or highly processed components like pre-made sauces.
- Not Always Ultra-Processed: Traditional meal kits, where you cook the meal yourself, are typically not ultra-processed, unlike many fast-food or frozen dinners.
- Ingredient Check is Key: The best way to assess a meal kit is to check the ingredient list for sauces and seasoning packets, which may contain high sodium, added sugars, and additives.
- Choose Wisely: Opting for meal kit services that emphasize whole, fresh ingredients and offer dietary customizations (like low-sodium) is a strategic way to eat healthier.
- Healthier Than Fast Food: For many people, meal kits represent a significant improvement over eating takeout or highly processed, ready-to-eat meals, encouraging more home cooking.
- Control is Possible: Cooking with a meal kit gives you more control over ingredients and preparation than most convenience foods, allowing you to limit processing and additives.
Faqs
Are all meal kits processed? Yes, technically all meal kits are processed to some degree, as their ingredients are washed, cut, and portioned. However, the term is broad and the level of processing varies significantly.
Are meal kits considered ultra-processed food (UPF)? No, most traditional meal kits are not considered ultra-processed. The ultra-processed classification is reserved for industrial formulations with many additives. However, kits containing sauces with numerous unfamiliar ingredients may lean toward higher processing.
How can I tell if my meal kit contains ultra-processed ingredients? Read the ingredients list carefully, especially for sauces, marinades, or seasoning packets. Look for unfamiliar additives, preservatives, or high fructose corn syrup. A very long ingredient list is also a red flag.
