Understanding the NOVA Classification System
To determine if store-bought hummus is ultra-processed, it's essential to first understand the NOVA classification system. Developed by researchers in Brazil, this system categorizes foods into four groups based on the extent and purpose of their processing, not their nutritional content alone. The four groups are:
- Group 1: Unprocessed or Minimally Processed Foods: Whole foods in their natural state or with minimal alterations like drying, crushing, or pasteurizing. Examples include fresh fruits, vegetables, nuts, and lentils.
- Group 2: Processed Culinary Ingredients: Ingredients derived from Group 1 foods that are used in food preparation, such as oils, flour, salt, and sugar.
- Group 3: Processed Foods: Relatively simple products made by adding Group 2 ingredients to Group 1 foods. Think canned vegetables, simple cheeses, and artisan bread.
- Group 4: Ultra-Processed Foods: Industrial formulations made with five or more ingredients, often including additives, preservatives, and substances not typically found in a home kitchen. These products are designed for convenience and a long shelf-life.
Based on this framework, commercially manufactured hummus containing additives and preservatives fits squarely into the fourth category. A traditional homemade hummus, made with chickpeas, tahini, lemon juice, garlic, and olive oil, would be a processed food (Group 3), or even a minimally processed food (Group 1) if the ingredients are fresh and unprocessed. The industrial additives are the key difference that pushes a product into the 'ultra-processed' category.
The Ingredients That Make Hummus Ultra-Processed
When you check the ingredient list on a tub of store-bought hummus, you'll often find more than just the basic components. Many commercial brands use a variety of additives to improve texture, preserve freshness, and reduce costs. These include:
- Preservatives: Ingredients like potassium sorbate or citric acid are added to extend the product's shelf life, preventing spoilage and keeping it safe for a longer period.
- Stabilizers and Emulsifiers: Ingredients such as guar gum or carrageenan are used to maintain a smooth, consistent texture and prevent the ingredients from separating over time.
- Industrial Oils: Some brands use lower-cost industrial oils, such as sunflower or canola oil, instead of or in addition to the traditional extra virgin olive oil.
- Thickeners and Flavorings: Modified starches and natural or artificial flavorings may be included to enhance taste and consistency.
Homemade vs. Store-Bought: A Comparison
The difference in processing levels leads to notable contrasts between homemade and store-bought hummus. While both can be nutritious, the health implications and overall quality differ.
| Feature | Homemade Hummus | Store-Bought Hummus |
|---|---|---|
| Ingredients | Whole, fresh ingredients like chickpeas, tahini, lemon, garlic, olive oil, and spices. | May contain industrial ingredients like preservatives, emulsifiers, modified starches, and cheaper oils. |
| Processing Level | Minimal. Blending and seasoning are the primary steps. | Ultra-processed, due to the industrial formulation and use of additives for stability and shelf life. |
| Nutritional Profile | Higher in fiber and often lower in sodium, without unnecessary additives. The type of oil used (e.g., extra virgin olive oil) is controlled by the maker. | Nutritional quality can vary significantly by brand. Some may have higher sodium content or added sugars. |
| Taste and Texture | Fresh, vibrant, and customizable. The texture is often creamier and lighter. | Can taste less fresh due to preservatives. Texture may be overly thick or pasty. |
| Shelf Life | Shorter, typically a week in the refrigerator. | Much longer, often two weeks or more, due to preservatives. |
| Cost | Often more cost-effective when made in larger batches from basic ingredients. | Can be more expensive per serving, but offers convenience. |
Can Ultra-Processed Foods Be Part of a Healthy Diet?
The ultra-processed classification isn't an automatic disqualification for a food item. While a high intake of ultra-processed foods is linked to negative health outcomes like obesity, heart disease, and diabetes, some items within the category still provide nutritional value. Wholemeal sliced bread and certain types of baked beans, for example, can be classified as ultra-processed but still contribute fiber and nutrients to a diet.
The key is nuance and moderation. Store-bought hummus, despite being ultra-processed, is still often a better choice than other highly processed snacks like potato chips or sugary cereals, as it provides a good source of fiber and protein from chickpeas. Nutritionist advice suggests focusing on a healthy, balanced diet rich in fruits, vegetables, and whole foods, and consuming ultra-processed items in smaller, less frequent amounts.

How to Make a Healthier Choice
To navigate the world of store-bought hummus, or to make your own, consider these options:
- Read the Label Carefully: Look for brands with the shortest ingredient list possible, ideally without preservatives like potassium sorbate or unfamiliar emulsifiers.
- Look for High-Quality Ingredients: Opt for brands that use extra virgin olive oil and simple, recognizable ingredients. Some organic brands may offer a less-processed option.
- Make It at Home: Making your own hummus is surprisingly easy and quick, taking only a few minutes with a food processor. This gives you complete control over the ingredients, allowing you to use high-quality, whole foods and avoid additives.
- Embellish Simple Hummus: If you want convenience, purchase a simpler store-bought variety and enhance it at home with fresh lemon juice, a drizzle of high-quality extra virgin olive oil, fresh herbs, or toasted spices.
Conclusion
So, is store-bought hummus ultra-processed? The answer, according to the widely used NOVA classification, is often yes. The industrial addition of preservatives, stabilizers, and alternative oils pushes many commercial varieties into this category. However, this doesn't render them unhealthy. They can still offer nutritional benefits, and for those with busy lifestyles, they provide a convenient source of protein and fiber. The best approach is to be an informed consumer, read labels, and consider homemade alternatives or minimally processed brands when possible. A balanced diet focused on whole foods remains the gold standard, with ultra-processed items used judiciously.
Frequently Asked Questions
How is ultra-processed different from just 'processed'?
'Processed' generally refers to any alteration of a food from its natural state, which includes simple actions like freezing or pasteurization. 'Ultra-processed' is a more specific term for industrial formulations containing many additives and substances not typically used in home cooking.
What are some examples of ultra-processed foods besides hummus?
Other common ultra-processed foods include soft drinks, packaged cookies, certain breakfast cereals, instant noodles, and many ready-to-eat meals.
Does organic store-bought hummus avoid the 'ultra-processed' label?
Not necessarily. While organic brands might use organic ingredients, they can still contain industrial additives and preservatives to extend shelf life, which would classify them as ultra-processed under the NOVA system.
Is homemade hummus always better for you?
Homemade hummus gives you full control over the ingredients, allowing you to avoid additives, regulate sodium, and use high-quality olive oil. This often results in a fresher, tastier, and potentially more nutritious product.
