Understanding the NOVA Classification System
To answer the question of whether baked beans count as ultra-processed food, it is essential to first understand the NOVA classification system. Developed by Brazilian scientists, this system categorizes foods based on the nature, extent, and purpose of their processing, rather than solely on nutritional content. The four categories are:
- Group 1: Unprocessed or Minimally Processed Foods. These are foods in their natural state, or those minimally altered to extend shelf life, such as fresh fruits, vegetables, grains, and frozen vegetables.
- Group 2: Processed Culinary Ingredients. These are substances like oils, fats, salt, and sugar derived from Group 1 foods. They are not meant to be eaten alone but are used for cooking and seasoning.
- Group 3: Processed Foods. Simple processed foods are made by adding Group 2 ingredients (salt, sugar, oil) to Group 1 foods. Examples include canned vegetables in brine, simple cheeses, and freshly baked bread with minimal ingredients.
- Group 4: Ultra-Processed Food and Drink Products. These are industrial formulations with multiple ingredients, including many additives not typically used in home cooking. They are designed to be convenient, highly palatable, and have a long shelf life. Examples include sugary cereals, packaged snacks, and soft drinks.
Why Canned Baked Beans Are Classified as UPF
Based on the NOVA system, most commercially produced canned baked beans fall squarely into the ultra-processed category. While they start with minimally processed beans and tomatoes (Group 1), their transformation involves a mix of ingredients and processes that move them far beyond simple processing.
- Multiple Ingredients: Standard recipes for canned baked beans often include more than five ingredients. Beyond the beans and tomatoes, a typical can will contain sugar, salt, and various additives, including modified starches, flavourings, and thickeners.
- Additives Not Used in Home Cooking: Ingredients like modified cornflour or spice extracts are common in commercial brands but are not part of typical home cooking. These are included to achieve a specific texture, flavour, and consistency that mass-produced products require.
- Industrial Formulation: The overall process, including large-scale cooking, canning, and sterilisation, is an industrial formulation designed for convenience, shelf life, and profit, which is the very definition of a NOVA Group 4 product.
The Nutritional Nuance: A "Healthier" UPF?
While the UPF label might sound alarming, the story of baked beans is more complex. Nutrition experts highlight that not all UPFs are created equal, and baked beans represent one of the better options.
- Nutrient-Dense Base: At their core, baked beans are legumes, which are packed with fibre and plant-based protein. A half-can of baked beans provides a significant portion of the recommended daily fibre intake.
- Hidden Concerns: The main drawback lies in the sauce, which is typically high in added sugar and salt. Many brands offer reduced-sugar and salt versions, making them a healthier choice. Rinsing canned beans can also significantly reduce their sodium content.
- Overall Diet: Baked beans are often a vehicle for adding legumes to the diet, and when paired with other whole foods like wholemeal toast, they provide a well-rounded, affordable, and convenient meal.
Comparing Commercial vs. Homemade Baked Beans
To illustrate the processing difference, consider the journey of commercial baked beans versus a homemade version from scratch. The table below outlines the key differences.
| Feature | Commercial Baked Beans | Homemade Baked Beans |
|---|---|---|
| NOVA Classification | Group 4 (Ultra-Processed) | Group 1 (Minimally Processed) |
| Ingredients | Beans, tomato puree, sugar, salt, modified starch, flavourings, sometimes preservatives | Dried beans, tomato paste, onions, garlic, natural sweeteners (e.g., maple syrup or molasses), spices |
| Processing Steps | Soaking, partial cooking, sauce preparation, canning, sterilisation, sealing. | Soaking, cooking, combining ingredients. |
| Added Sugar | Often high, but reduced-sugar options are available. | Controlled by the cook; can be significantly lower or use natural alternatives. |
| Added Salt | Often high, though low-salt versions exist. | Controlled by the cook, typically much lower. |
| Convenience | Ready to eat or heat instantly. | Requires advanced preparation, including soaking and cooking. |
Tips for Making a Healthier Choice
If you want to include baked beans in your diet while minimising the negatives associated with ultra-processed foods, here are some actionable tips:
- Read Labels Carefully: Choose brands that offer reduced-sugar and reduced-salt options. Compare the nutritional information on different cans to find the healthiest version.
- Rinse and Drain: If buying regular canned beans, drain and rinse them thoroughly to wash off a significant portion of the added sodium.
- Opt for Plain Canned Beans: Consider buying plain canned beans (like cannellini or haricot beans) and making your own tomato-based sauce at home. This allows full control over the amount of sugar, salt, and spices used.
- Batch Cook from Scratch: For the lowest level of processing, buy dried beans and make your own batch of baked beans. This requires more time but is the healthiest and freshest option.
- Mindful Consumption: Remember that even a healthier UPF should be part of a varied diet that includes plenty of minimally processed whole foods, such as fresh vegetables, fruits, and whole grains.
Conclusion
Yes, most commercially produced baked beans are classified as ultra-processed foods under the NOVA system because of their multiple additives and industrial processing. However, this label does not tell the whole story. The core ingredients provide valuable fibre and protein, which can be part of a healthy and balanced diet when consumed in moderation. By choosing reduced-sugar and salt varieties or making them from scratch, you can enjoy the nutritional benefits while mitigating the downsides of excessive processing. Ultimately, the context of your overall diet and the choices you make at the supermarket determine the health impact of this popular cupboard staple.
