There is a warning for parents around the world; vegan diets for infants are dangerous.
A new study by the UCL Great Ormond Street Institute of Child Health in the UK and the Children's Memorial Health Institute in Poland compared infants on a vegan diets and those who were omnivores.
It found that vegan kids might have slightly lower levels of cholesterol and body fat, but on average they were three centimetres shorter, had weaker bones and were three times more likely to be B12 deficient.
One of the co-authors of the study is professor Jonathan Wells who told Mike Hosking each diet comes with health risk and reward.
“Whatever you eat there some benefits and there are some risks and those benefits and risks aren’t just manifesting now, they’re distributed over the life course.”
