Soy milk: how to choose a plant-based drink to suit your lifestyle

Soy milk appeals to people who want to reduce their intake of dairy products, fancy a change from traditional milk at breakfast or want to rediscover the taste of ready-to-drink Asian beverages. However, not all products are the same or meet the same needs. Between ‘less sugar’ recipes, flavoured versions and powdered formats, it is worth taking the time to read the label.

Common pitfalls when buying soy milk

1. Confusing ‘plant-based’ with ‘free from allergens’

A soy drink can replace cow’s milk in many recipes and everyday routines. However, it contains soya, an allergen that must be clearly shown on the packaging. Some products also contain milk powder, cereals containing gluten, sesame or nuts.

The product information for VitaMilch Soy Milk 300 ml, for example, lists both soya extract and whole milk powder. It is therefore not automatically suitable for someone looking for a strictly plant-based drink, even if its presentation describes it as a lactose-free alternative. Before ordering, always check the ingredients list and allergen declaration.

2. Relying solely on the ‘less sugar’ claim

‘Less sugar’ does not mean ‘sugar-free’. Vitasoy Soya Bean Milk with Less Sugar contains 2% added sugar, according to its ingredients list. It may be less sweet than a classic recipe, but that does not make it a drink with no added sugars.

For a reliable comparison, start by checking the nutritional table per 100 ml, then adjust the figures to the amount you actually drink. A 250 or 300 ml individual carton can easily contain more than twice the amount shown per 100 ml.

3. Overlooking format and storage

A ready-to-drink plant-based beverage in a small carton is particularly convenient at work, when travelling or for occasional consumption. The 1 L format is better suited to cereal, hot drinks and cooking, but the bottle will generally need to be kept in the fridge after opening.

Soy powder takes up less space and allows you to prepare only the amount you need. On the other hand, you need to check its composition, follow the recommended dosage, dissolve it thoroughly and store it correctly after opening. The best format is therefore above all the one that matches your consumption habits.

What to check on the label

Composition and soya content

Look at where soya appears in the ingredients list. Depending on the product, it may be present as an extract, powder or beans, with a percentage sometimes provided by the manufacturer. Flavoured recipes often also contain cocoa, sesame, cereals, sugar or various flavourings.

If you are looking for a plant-based drink that is high in protein, the nutritional table is generally more informative than the marketing claims. As an indication, the Vitasoy less-sugar version states 7 g of protein per 100 ml, according to the information published on its product page. Other soy drinks may show noticeably different values.

Sugars, fat and serving sizes

The sugar content can vary considerably between a plain soy drink, a flavoured recipe and a cereal-based version. Check the ‘carbohydrates’ and ‘of which sugars’ lines, as well as the ingredients list. Sugar, maltose syrup, fructose and maltodextrin are among the ingredients to look out for.

Flavoured soy drinks, such as Vitasoy’s chocolate version, are often more indulgent, but they are not intended for the same use as a less-sweet recipe. For everyday breakfast, a neutral-tasting drink will often be more versatile. For a break or snack, a cocoa or sesame version may be a better choice.

Allergens and regulatory information

In France and the European Union, allergens must be highlighted in the ingredients list. In particular, check for:

  • soya, naturally present in soy-based drinks and powders;
  • nuts, particularly in almond drinks;
  • gluten, in some cereal- or barley-based recipes;
  • milk, when the recipe contains milk powder or a dairy ingredient;
  • sesame, common in some flavoured Asian drinks.

The claims ‘organic’, ‘lactose-free’ and ‘plant-based’ should always be considered alongside the ingredients list and the information shown on the packaging. You can also compare almond milk, coconut milk and other lactose-free plant-based drinks, bearing in mind that they have different nutritional profiles and different uses in cooking.

Frequently asked questions about soy milk

Is soy milk suitable for people who are lactose intolerant?

A drink made exclusively from plant-based ingredients generally contains no lactose. However, some products may contain milk powder or other dairy-derived ingredients. Do not rely solely on the product name: check the ingredients list and allergens.

How should a soy drink be stored after opening?

Follow the manufacturer’s recommendations. Most cartons should be refrigerated after opening and consumed quickly, often within 24 to 48 hours. Small individual formats are a good way to reduce waste if you do not drink this type of beverage regularly.

Is soy milk powder cheaper to use?

It depends on the price of the pack, the number of portions it produces and the amount of water required. To compare it with a pack of ready-to-drink soy beverages, calculate the price per 100 ml prepared, taking into account the recommended dosage and whether individual sachets are included. Powder is often more convenient for storage and transport, while cartons remain unbeatable when simplicity is the priority.
