Study Links Plant-Based Dairy Swaps to Iodine Deficiency

The problem is that plant-based products have very little iodine unless companies add it. The body uses iodine to help children grow and to support the brain. In the UK, dairy gives children about half of their iodine. But companies do not have to add vitamins and minerals to plant-based products. The researchers looked at many plant-based milks, yoghurts and cheeses. Only 12% had added iodine.

If people stopped eating dairy completely, 80% of teenage girls would not get enough iodine. The researchers want a new rule that makes companies add iodine. Some brands, like Alpro and some Oatly drinks, already do this. A UK dietitian, Nichola Ludlam-Raine, said people who switch are not always at risk, because their whole diet matters. She told shoppers to check the label.
