What Is Plant-Based Milk?

Simply put, plant-based milk is a liquid made by blending water with various plant ingredients.

These can be nuts, seeds, grains, or legumes.

After blending, the mixture is usually strained to remove solids, leaving behind a creamy, milk-like beverage.

Unlike dairy milk, plant-based milk doesn’t come from cows, goats, or other animals.

This makes it naturally lactose-free and often easier to digest for many people.

But the differences go beyond just digestion—they also include environmental impact, taste, and nutrition.

Popular Types of Plant-Based Milk

There’s a huge variety of plant-based milks, each with its own flavour, texture, and nutritional profile.

Almond milk is light, low in calories, and slightly nutty, making it perfect for smoothies, coffee, and cereal.

Soy milk has been around for centuries and is high in protein, often fortified with vitamins like B12 and calcium, making it nutritionally closer to dairy milk.

Oat milk has skyrocketed in popularity recently, especially in coffee shops, thanks to its naturally sweet flavour, creamy texture, and frothing ability.

Coconut milk is rich and tropical, ideal for curries and desserts, though it’s higher in fat.

Rice milk is sweet and thin, often recommended for people with multiple allergies, but it’s low in protein.

Other varieties like hemp milk, cashew milk, flax milk, and pea protein milk offer unique flavours, textures, and nutritional benefits, giving you plenty of options to explore.

Nutritional Comparison: Plant-Based Milk vs. Dairy Milk

When it comes to nutrition, plant-based milks vary widely.

Dairy milk is naturally rich in protein, calcium, and vitamin B12, and contains saturated fats that some people try to limit.

Cow’s milk has about eight grams of protein per cup, along with roughly 12 grams of carbohydrates, most of which come from natural sugars like lactose.

It’s also a good source of calcium and vitamin D if fortified, but it can be difficult to digest for those who are lactose intolerant.

Plant-based milks, on the other hand, have a much wider range of nutrients depending on the type.

Soy milk is closest to dairy in protein content, also containing roughly seven grams per cup, and many brands are fortified with calcium and vitamins.

Almond milk is low in calories and fat but contains only one gram of protein per cup unless fortified, while oat milk has slightly more carbohydrates, a naturally sweet taste, and around three grams of protein per cup.

Coconut milk is high in saturated fats and low in protein, whereas rice milk is naturally sweet but very low in protein and can be higher in sugar.

Fortified plant-based milks help close some nutritional gaps with dairy, but protein intake may still be lower unless you choose soy, pea, or other protein-rich varieties.

The key takeaway? If you’re swapping dairy for plant-based milk, consider your nutritional goals.

For protein and calcium, soy or pea protein milk is best.

For fewer calories, almond milk wins. For creamy coffee froth, oat milk takes the crown.

Health Benefits of Plant-Based Milk

Switching to plant-based milk can have several advantages.

It’s naturally lactose-free, which makes it easier on the stomach and can prevent bloating and discomfort for those sensitive to dairy.

Some plant-based milks, like almond and rice milk, are lower in calories and fat than cow’s milk, supporting weight management, while coconut milk, higher in fat, can provide satiety and flavour.

Certain varieties like soy and almond milk are low in saturated fat and cholesterol, which supports heart health.

Fortified plant-based milks also provide calcium, vitamin D, and vitamin B12, bridging the nutritional gap with dairy milk.

Beyond personal health, plant-based milk is generally more environmentally friendly than dairy, using less water, producing fewer greenhouse gases, and requiring less land.

Potential Drawbacks of Plant-Based Milk

While plant-based milks have benefits, there are also some things to keep in mind.

Protein content varies widely; almond and rice milk are low in protein, which may not be ideal if milk is a key protein source in your diet.

Flavoured varieties often contain added sugar, so unsweetened options are usually best.

Nut-based milks can trigger allergies, and plant-based milk is often more expensive than dairy.

Finally, some homemade or unfortified milks may lack essential vitamins, so it’s worth checking labels or considering fortified versions.

How to Choose the Right Plant-Based Milk

Choosing the best plant-based milk depends on your preferences, dietary needs, and how you plan to use it.

For drinking or coffee, oat and soy milk work best because of their creamy texture and frothing ability.

For cooking, coconut or cashew milk adds richness to curries, soups, and desserts.

For protein, soy milk or pea protein milk offers the most per serving.

If you’re aiming for low calories, unsweetened almond milk is light and versatile.

For allergies, rice milk or hemp milk is generally safer.

Tips for Using Plant-Based Milk

Plant-based milk is extremely versatile.

Substitute it in smoothies and shakes, froth it for lattes, replace dairy milk in baking, pour it over cereal or oatmeal, or use it in cooking for creamy sauces and curries.

Homemade plant-based milk is easy to make: soak nuts, seeds, or grains overnight, blend with fresh water, strain, and optionally add salt, sweetener, or vanilla.

Homemade milk is fresher, chemical-free, and customisable, and can even be more cost-effective over time.

Storage and Shelf Life

Most store-bought plant-based milks are pasteurised and can last for several weeks unopened.

Once opened, refrigerate and consume within 5–7 days.

Homemade milks are more perishable and should be used within 3–5 days.

Always shake before use, as separation is natural.
