Putting children on strict vegan diets is "unethical" and could harm their development, a US scientist has argued. Lindsay Allen, of the US Agricultural Research Service, attacked parents who insisted their children lived by the maxim "meat is murder".
Animal source foods have some nutrients not found anywhere else, she told a Washington science conference.
The Vegan Society dismissed the claims, saying its research showed vegans were often healthier than meat eaters.
Professor Allen said: "There have been sufficient studies clearly showing that when women avoid all animal foods, their babies are born small, they grow very slowly and they are developmentally retarded, possibly permanently."
"If you're talking about feeding young children, pregnant women and lactating women, I would go as far as to say it is unethical to withhold these foods [animal source foods] during that period of life."
She was especially critical of parents who imposed a vegan lifestyle on their children, denying them milk, cheese, butter and meat.
"There's absolutely no question that it's unethical for parents to bring up their children as strict vegans," she told the annual meeting of the American Association for the Advancement of Science (AAAS).
She said the damage to a child began while it was growing in the womb and continued once it had been born.
However, the claims have been dismissed by the Vegan Society in the UK.
In a statement, it said increasing numbers of people were opting for a plant-based diet.
Kostana Azmi, the chief executive officer, said: "The vegan diet can provide you with more energy, nutrition, and is bursting with goodness."
She said plant sources were sometimes a safer, and cheaper source of nutrients.
For instance, animal sources of omega-3 oils, needed for the development of the brain and nervous system, were often contaminated with pollutants, such as mercury in fish.
In addition, the vegan diet was often a healthier alternative. She said dairy and meat products were rich in saturated fat, while plant based diets were low in it.
The society does recommend that vegans supplement their diet with vitamin B-12 pills.

Bonnie - I have been saying this forever. I believe putting children on strict vegan diets may be causing their children permamnent physical, mental, and emotional damage. There is no possible way that a child can develop properly as a vegan. I have seen it too many times in my practice.
