Seed oils are undoubtedly the worst offender in plant-based milks. These oils are added to create a ‘creaminess’ and to ensure the milk doesn’t separate. Unfortunately, rather than using a healthy oil like olive oil to do this, the large majority of companies use cheap seed oils like sunflower (rapeseed) or canola oil.
Research has suggested seed oils are fuelling the rise in colon cancer in young people[1]. A recent study from the University of California found that seed oils drive inflammation, damage DNA, and interfere with the natural repair mechanisms that prevent the formation of tumours.
We also know that seed oils contain a high proportion of omega-6 fatty acids. While we need some omega-6 in our diet, when we consume excess omega-6 fats, and insufficient omega-3, it propels our body into a state of low-grade inflammation which has been linked to many chronic diseases including type 2 diabetes and cancer.
Dipotassium Phosphate is often used as a preservative and flavour-enhancer. A swift Google search assures you it’s ‘considered safe by the FDA’ but further digging shows links to intestinal inflammation [2] and anecdotal accounts of allergies. Convenient to overlook - but better to avoid.
Many commercial plant-based milks are fortified with vitamins in their cheaper, less easily absorbable forms. These include calcium carbonate as well as Vitamin D2 and cyanocobalamin B12 - the latter two are man-made synthetic forms of these vitamins which are a lot harder for the body to assimilate.

‘Barista’ plant-based milks are ubiquitous at cafes and they all contain seed oils. I’ve recently taken to ordering an ‘ice-long black’ when out or occasionally adding a ‘dash’ of oat milk. When it comes to kids, unless they are lactose intolerant, it's actually better for them to have a dairy-milk babycino. If they are intolerant, you might like to try something like an iced peppermint tea – a bit grown-up and no nasties.
