Not long ago, ordering coffee with regular cow’s milk was considered almost passé in certain circles. But the wellness narrative is shifting. As Anastasia Yavorska writes in her blog on Vogue UA, the uncomfortable truth about plant-based milk is surfacing — and cow’s milk is reclaiming its reputation.
French biochemist Jessie Inchauspé, known as the Glucose Goddess, sums it up: “Plant-based milk was positioned as cleaner, lighter, more modern and therefore automatically healthier. But from a metabolic standpoint, that is far from always true.”
Research shows cow’s milk causes significantly fewer glucose spikes than oat or rice milk — the two most popular plant-based variants. Cereal-based drinks are made from starch, which converts rapidly to sugar in the bloodstream. The fat in whole cow’s milk acts as a natural buffer, slowing glucose absorption and extending satiety. When the fat was removed in the low-fat trend of the 1980s and 90s, lactose began entering the bloodstream far faster — the opposite of the intended effect.
Whole cow’s milk delivers around 7g of protein per large glass, supports metabolic stability without sugar spikes, and has a low glycaemic index. Fermented dairy products — plain unsweetened yoghurt and kefir — add prebiotic benefits for gut health.
For plant-based drinkers, the advice is to read labels carefully: only nuts or grains and water, no stabilisers, thickeners or added sugars. Oat and rice milk are best consumed after fibre- and protein-rich meals to blunt their glycaemic impact.
The return of whole cow’s milk to health-conscious diets is not a step back — it is evidence that modern wellness culture is learning to distinguish what merely seems healthy from what the science actually supports.
