Understanding Ultra-Processing and the NOVA Classification
To understand what alternative milk is not ultra-processed, it's essential to grasp the NOVA food classification system. Developed by researchers in Brazil, this system groups foods into four categories based on the nature, extent, and purpose of their processing.
The NOVA Categories
- NOVA 1: Unprocessed or Minimally Processed Foods: These are natural foods altered only to aid preservation or usability. Examples include fresh fruits, vegetables, grains, and nuts. Homemade almond milk made only from almonds and water falls into this category.
- NOVA 2: Processed Culinary Ingredients: These are substances like oils, sugar, and salt, which are not meant to be eaten on their own but are added to NOVA 1 foods to create dishes.
- NOVA 3: Processed Foods: Products made by adding NOVA 2 ingredients to NOVA 1 foods. Think canned vegetables, simple breads, or cheeses.
- NOVA 4: Ultra-Processed Foods: Formulations made mostly or entirely from substances derived from foods, such as protein isolates, hydrogenated oils, emulsifiers, sweeteners, and artificial flavors. Many popular alternative milks fall into this category due to the inclusion of these industrial additives.
How to Identify Non-Ultra-Processed Alternative Milks
When choosing a plant-based milk, the ingredient list is your best friend. A good rule of thumb is to look for a short list with ingredients you recognize from your own kitchen. The fewer ingredients, the better. Here’s what to look for:
Key Indicators of Minimal Processing
- Simple Ingredients: The best choices typically contain just water, the main nut/seed/grain (e.g., almonds, oats, soy), and sometimes a pinch of sea salt. Some may also include small amounts of a natural sweetener like dates.
- Unsweetened Varieties: Opt for products explicitly labeled "unsweetened" or "original unsweetened." Many sweetened versions contain high amounts of added sugars, pushing them into the ultra-processed category.
- Organic Options: Many organic alternative milks are less likely to contain synthetic additives. However, be aware that organic products, by law, cannot be fortified with vitamins and minerals.
Common Additives to Avoid
- Gums and Thickeners: Ingredients like xanthan gum, gellan gum, guar gum, and carrageenan are used to stabilize the product and prevent separation. While some are more benign than others, they are industrial additives and a key indicator of ultra-processing.
- Added Oils: Seed oils like rapeseed, sunflower, and canola oil are often added to enhance texture and creaminess. These oils are typically highly refined and high in inflammatory omega-6 fatty acids.
- "Natural Flavors": This is a broad, unregulated term that can hide a variety of complex, industrially created chemical additives.
- Isolated Proteins: Some newer plant milks, like pea milk, are made from extracted pea protein isolate, which is a key marker of ultra-processing.
Comparison: Homemade vs. Ultra-Processed Alternative Milk
| Feature | Homemade Alternative Milk | Ultra-Processed Alternative Milk |
|---|---|---|
| Ingredients | Whole nuts, seeds, or grains; water; salt; optional natural sweeteners (dates) | Added oils, gums, stabilizers (carrageenan, xanthan gum), lecithin, and natural flavors |
| Processing | Blending and straining. Minimal to no processing. | Industrial extraction, homogenization, emulsification, and pasteurization. Extensively processed. |
| Nutritional Profile | Contains whole-food nutrients and fiber (if unstrained). | May be fortified with vitamins and minerals, but often contains unhealthy additives. |
| Shelf Life | Short, typically 3-6 days refrigerated. | Long, sometimes lasting months in the cupboard. |
| Taste & Texture | Fresh, clean, and often thicker. Some natural separation occurs. | Homogenized, creamy, and can have a distinct, unnatural sweetness or flavor. |
Making Your Own Non-UPF Alternative Milk
The most reliable way to guarantee a non-ultra-processed alternative milk is to make it yourself. It's surprisingly simple and allows you to control every single ingredient.
Simple Homemade Almond Milk Recipe
- Ingredients:
- 1 cup raw almonds
- 4 cups filtered water
- Pinch of sea salt (optional)
- 1-2 dates (optional for sweetness)
- Instructions:
- Soak: Place almonds in a bowl and cover with water. Soak for at least 8 hours or overnight.
- Rinse: Drain and rinse the soaked almonds well.
- Blend: Add the almonds, 4 cups of filtered water, and optional salt and dates to a high-speed blender. Blend on high for 1-2 minutes until smooth and creamy.
- Strain: Pour the mixture through a nut milk bag or fine-mesh sieve lined with cheesecloth into a large bowl. Squeeze out all the liquid to extract the milk.
- Store: Transfer the almond milk to an airtight container and refrigerate for up to 4 days. Shake well before each use as natural separation will occur.
Conclusion: Choosing a Healthier Option
While the convenience of store-bought alternative milks is appealing, many fall into the ultra-processed category due to added oils, gums, and flavors. To find a true, non-ultra-processed option, prioritize products with minimal ingredients—ideally just the base ingredient, water, and salt. The simplest and most certain route to a non-UPF milk, however, is making it yourself at home. By reading labels and understanding what to avoid, you can make more informed choices for a healthier diet.
