I caught the end of this at lunch time and was unimpressed by what I heard. Now I have read the entire segment I am still unimpressed, and seriously hoping that they start this after I'm dead. I have no dairy in my diet as I cannot digest it, so the dairy thing doesn't bother me. However nearly all fresh fruit or vegetables triggers my IBS, so my diet is very limited. The last few years thanks to loads of exercise and an unhealthy diet I am actually feeling the best I have been since I was a teenager could eat anything.
My Mum however found it most amusing as she is a livelong vegetarian, not through ideology but because she never liked the taste or texture of meat (she dislikes fake meat just as much). As a child (born 1947) she was informed she wouldn't be able to have babies, or live a long healthy life because of her lack of meat. I suppose you could say she's proven them wrong!
I'm afraid I have no plans on changing my diet (nor does my Mum). I'm sure if we wait a while someone will produce another diet.
