From Matthew Stevens, Sydney, Australia
While the gradual shift to a more sustainable, plant-based diet globally is a good thing, I feel some concern at the news that UK company Moolec has created soya beans with 25 per cent pig protein (8 July, p 17).
I am one of the rare but growing number of people with mammalian meat allergy (caused by an allergic reaction to a sugar molecule on the surface of nearly all mammalian cells, which is triggered by an aberrant response to tick bites). So I would want either to know that such products had eliminated this sugar epitope or to be warned if foods contained it, so I could avoid them. Safe recourse to plant proteins could become more difficult.
