Everything you need to know about potato milk
Long gone are the days when vegans or anyone with a dairy allergy would struggle to find suitable milk alternatives for their morning brew.
Now, there’s a whole range of options out there – from the well-established likes of almond, oat and soy milk, to the more left field variations, including cashew, hemp... and the latest arrival on the market: potato milk.
Sure, it might not sound quite as glamorous or exotic as macadamia nut milk, but it’s set to be the next big thing – Waitrose included potato milk in its annual Food & Drink Report as one of the top trends of 2022, saying: “Low in sugar and saturated fat, it’s set to dominate coffee shop menus in the coming months.”
So what actually is potato milk? It’s “the diluted starches from potato”, explains Sophie Medlin, dietitian and founder of City Dietitians (citydietitians.co.uk).
“It looks like milk because of the starchy nature of the potatoes, but it is actually just starchy water with some stabilisers.”
The health benefits
On its own, Medlin says “there are no benefits to drinking potato milk” – what you need to find is a product that’s been “fortified with calcium, vitamin D, B vitamins and iron”.
Plant-based nutritionist Rohini Bajekal (plantbasedhealth professionals.com) also says fortified milks are beneficial in being “low in saturated fat and allergen-friendly”.
So how does it compare to other milks? While Medlin calls cow’s milk a “power player” in the nutrition stakes, Bajekal suggests it’s “unnecessary within a healthy balanced diet” – but potatoes might not come out on top in the plant-based world.
Medlin adds: “I generally favour fortified soya milk for its amino acid profile or a nut-based milk, as they contain more protein compared to milks made from starches like rice, oats and potatoes.”
Bajekal is a big fan of soya alternatives, saying: “Unlike potato milk, soya milk is also far higher in protein.”
The environmental benefits
Swedish brand DUG (dugdrinks.com) says there are a whole lot of environmental benefits to the drink, suggesting its potato milk has a 75% lower climate footprint than dairy milk, as well as “twice as efficient as growing oats in terms of land use”, while also using 56 times less water to grow compared to almonds.
How you can drink it
Potato milk is becoming more widely available to buy – DUG is now available in Waitrose – and at £1.80, it’s pretty much on a par with the price of other non-dairy alternatives, which tend to be more expensive than cow’s milk.
Alternatively, you can make your own – although this won’t be fortified, so is unlikely to have many health benefits. It’s also more laborious than popping to the shops, but ultimately pretty easy – all you have to do is boil potatoes until soft, blend with water until you have the right consistency – at this point you can add flavourings or a sweetener as desired – then strain through a muslin cloth.
