Soy Milk Buying Guide: How to Choose the Right Option

With plant-based drink aisles growing longer by the day, it can be hard to know where to start. Whether due to lactose intolerance, a vegan diet, or simply the search for a more digestible milk alternative, soy milk stands out as a top-tier option. Rich in plant-based protein and incredibly versatile, it now comes in a multitude of varieties.

This guide is here to help you navigate the options. As the Head of Product Recommendations at Joybuy, my role is to give you the keys to choosing the soy drink that truly fits your tastes and lifestyle—all without the marketing jargon.

How to Choose the Right Soy Drink

A few simple criteria are all you need to find the perfect product.

1. Read the Ingredient List Carefully

The composition of a soy drink varies enormously from one brand to another. Your first step: check the sugar content. If you're mindful of this, opt for a low-sugar soy milk option. Also, be sure to check for additives, flavourings, or added oils. As a general rule, a short ingredient list is a good sign.

2. Consider How You'll Use It

Not all soy drinks are created equal, depending on their intended use.

• For drinking straight or with cereal: A classic, plain, or lightly sweetened soy drink will do the trick perfectly. A multigrain soy drink will offer a richer texture and a more complete nutritional profile, ideal for a breakfast that keeps you full.
• For cooking and baking: An unsweetened version with a neutral taste is essential to avoid altering the flavour of your savoury dishes or cakes.
• For smoothies: Most varieties will work, but a protein-fortified drink will make your smoothie even more nourishing.

3. Check the Protein Content

One of the major advantages of soy milk is its high content of plant-based protein. This is what sets it apart from many other plant-based drinks, such as those made from almonds or rice. If this is a key criterion for you, compare the labels: a good soy drink typically contains between 2 and 4 grams of protein per 100 ml.

Soy Milk: Your Questions, Our Answers

Is soy milk a good alternative to cow's milk?

Yes, it's an excellent milk alternative for several reasons. Naturally lactose-free, it is very easy to digest for those with an intolerance. It also boasts a significant content of complete plant-based protein. However, be aware that their nutritional profiles differ: cow's milk is naturally rich in calcium, whereas soy drinks often need to be fortified to provide an equivalent amount. The final choice depends on your needs and tastes.

How should I store soy drink after opening it?

Once the carton is opened, a soy drink must be kept in the refrigerator. It is recommended to consume it within 24 to 72 hours, following the manufacturer's instructions on the packaging. Remember to close the cap tightly to preserve its freshness.

Can you cook with soy milk?

Absolutely! Soy drink is a true Swiss Army knife in the kitchen. Unsweetened versions are ideal for savoury dishes (soups, purées, sauces...). Sweetened versions are perfect for desserts, crêpes, custards, and cakes. Its protein content even allows it to curdle slightly, which is a real bonus for the texture of certain recipes.
