Farmers For Action said the vegan promotion did not highlight ‘just how many worms and soil microbes lose their lives during soil preparation to grow the vegetables your veganism requires’.
Farmers For Action (FFA) Northern Ireland have written a letter to the Vegan Society to be ‘held account’ on their propaganda.
FFA UK NI co-ordinator William Taylor questioned the society with ‘grave concerns’ about young people becoming vegans early in life and falling short of the ‘natural necessary nutrients’ required during their growing years.
He said the youngsters should be able to learn the full facts and consequences for their bodies in order to make the right decision about what to eat.
It came as vegan group Go Vegan World said it would not support any animal welfare campaign as it would not be in line with its ethos.
The letter said: “Farmers For Action UK NI are most concerned about the high profile veganism message being put out across the UK.
“Particularly in relation to its effect on growing school children and young people who very much need their full intake of calcium, iron and other essential natural nutrients for them to grow and develop.
“These youngsters must be told all of the facts and not the selected few, thus the question FFA would like your organisation to answer.
“Whilst FFA fully supports all sectors of farmers across the UK, we feel that your organisation must explain how your promotion does not highlight to these same growing school children and young people just how many worms and soil microbes lose their lives during soil preparation to grow the vegetables your veganism requires – this is the real world.
“Our question is simply this: Will your advertising in future and definition of veganism clearly state in equal size print that worms and soil microbes will die in the process of growing the vegetables required for veganism?”
