Plant milks are nothing new. Often derided as a modern fad, in fact plant milks have been around for hundreds of years, all over the world. Medieval monks drank almond milk on fast days. The earliest recipe for soy milk goes back to possibly the 1st century AD. Polynesian peoples may have been drinking coconut milk for 5,000 years.
Why are plant milks so popular?
Plant Milks are certainly going through something of a popularity boom. This is for a few reasons. They are suitable for vegetarians and vegans, meaning many places like cafes and schools / universities choose plant milks so everyone can drink them. They are also popular among people with lactose intolerance.
Where dairy based milks all tend to be similar in taste and profile, plant milks have a wide choice of flavours and uses. They also often have a lower environmental impact than dairy milk.

Plant milks don’t have the same nutritional profile as dairy milk but some offer close matches in terms of protein for example.. Many plant milks are fortified with:
- Calcium

- Vitamin D
- Iodine (in some cases)
Make sure to check labels to compare the nutritional benefits.
The environmental impacts of different plant milks[i]
One criticisms made against plant milks is that they have an environmental cost. This is true of all foods – plant milk is no exception. However, different plant milks have different environmental impacts. Generally, plant milks require fewer resources than dairy milk.
Different milks have different average greenhouse gas emissions and average water uses associated with them.

These figures show that plant milks on average generate a third of the greenhouse gases that dairy does – or less. They also use less water. Plant milks are overall a more sustainable choice than dairy for these reasons.
According to Our World in Data[ii],
‘Cow’s milk has significantly higher impacts than the plant-based alternatives across all metrics. It causes around three times as much greenhouse gas emissions; uses around ten times as much land; two to twenty times as much freshwater; and creates much higher levels of eutrophication.
If you want to reduce the environmental footprint of your diet, switching to plant-based alternatives is a good option.’
What’s the Best Plant Milk for You?
There is no single “best” plant milk. We all have different tastes and preferences – and different milks fulfil different roles better.
If your desire to avoid dairy milks is based on your health, then checking nutrition and fortification can help you choose the option that fits your lifestyle. For example, unsweetened plant milks are low in sugar.
Trying several types of milk is often the best way to find a favourite – so give a few a go and make sure to try them in your tea!
