A vegan diet is a valid way of life for those that choose to adopt it, and it has its place for consideration like other diets. Whether it is better than other diets is a moot point, and when there are claims that it will cure Diabetes or cancer then my hackles rise. Those of us here in the Forum must realise that we have a special and biassed interest in diets, and that this colours our thinking in a way that often opposes what may be quite applicable to the general public at large. For the BDA to take up promotion of veganism is not an evil, but it needs to be offered rather than pushed as a cure all for obesity. It is just another tool that will suit some but not all.
It seems to be perfectly possible to be vegan, and still adopt the principles of an LC diet and even LCHF so we should be able to accept it here as a viable tool as well. When the WFPB brigade start making claims fot their way if life being of special benefit to a diabetic, then I will resist with vigour since there is absolutely no recognised scientific basis for their HCVLF diet working, and it is IMHO quite dangerous for T2D to adopt as a way of life at the extreme level they propose,
I personally will not be using a vegan diet, but certainly my LC diet has a significant increase in vegetable foods and healthy oils etc, so I am not anti-vegetarian. But a purist macrobiotic diet is another matter.
