What's In Your Food · Reformulation · The takeover
People say Dairy Milk isn’t what it was. Some of that is true. The bar is smaller, and there is palm and shea fat in it. But the story usually told — an American takeover that broke a promise and swapped the milk for palm oil — gets the most shareable parts wrong. Here is what the record shows, and what it means for your health, which is less than you might think.
The UK Dairy Milk ingredients list, from Cadbury’s own site, reads: milk, sugar, cocoa butter, cocoa mass, vegetable fats (palm, shea), emulsifiers (E442, E476), flavourings.
So yes, there is palm fat in it. But the law sets a hard limit. Milk chocolate sold in Britain may contain vegetable fats other than cocoa butter at no more than 5% of the total weight (the Cocoa and Chocolate Products Regulations 2003, from EU Directive 2000/36/EC). British chocolate’s use of vegetable fat was the reason for a long-running fight with other European countries over whether it could be called chocolate at all. It was a British habit long before Kraft arrived. The fat in Dairy Milk is still mostly cocoa butter and milk fat.
The famous palm-oil backlash was in Australia and New Zealand in 2009, under Cadbury’s own management, the year before Kraft bought it. Cadbury reversed it within months. That makes it a story about consumer pressure working, not about a new owner.
Cadbury announced in 2007 that Somerdale would close and production would move to Poland. What Kraft did wrong was to say, during the bid, that it believed it could keep the factory open, without knowing enough to say so. The Takeover Panel found the statements were not made to the required standard and criticised Kraft. That is a real failing, and a different one from “Kraft closed a British factory to move it to Poland”.
The clearest change is shrinkflation. Bars got smaller at similar prices: Toblerone’s wider gaps in 2016, the 200g Dairy Milk becoming 180g in 2022, and a rounder chunk shape in the early 2010s that took weight out. None of that is hidden, but it is easy to miss, and the price per 100g on the shelf label is the only reliable way to see it.
Whether the taste changed is harder. Many people say it did, and Mondelez says its recipes are high quality. I have not found a published before-and-after analysis of the recipe, so I cannot tell you which is right.
Less than the internet suggests. Palm oil is roughly 45% palmitic acid. Cocoa butter is about a quarter palmitic acid and a third stearic acid. In controlled feeding trials, palmitic acid raises LDL cholesterol more than stearic acid does (Mensink et al., 2003, a meta-analysis of 60 trials). So swapping cocoa butter for palm fat is, in principle, a small step in the wrong direction.
But the cap is 5% of the bar, shared with shea. In a 45g bar that is at most about 2g of non-cocoa vegetable fat, of which only part is palmitic acid. Next to the sugar, which is the first ingredient after milk, the fat swap is a rounding error. If Dairy Milk is a problem for your health, it is the sugar and the amount you eat, not the palm fat.
You are not imagining that Dairy Milk has changed. The bar is smaller and the label has palm fat on it. But the version of the story that travels best — broken promise, American owners, milk swapped for palm oil — gets the most shareable parts wrong.
