Well, you have your opinion and that's absolutely fine. All I can say is that with 25 years experience in the NHS, several of which have been spent in clinical research, I can see that what she says makes absolute sense.
Tbh, she's simply taking the evidence that's out there and pulling it together to present the findings in a coherent way. These aren't her ideas that she's presenting but other people's. The evidence is out there that the advice we've been fed (no pun intended) about what we should be eating is seriously flawed. A doctor said to me fairly recently that type 2 diabetes will bring down the health service and I wholeheartedly agree. Unfortunately though, with the likes of the British sugar industry and Kelloggs sponsoring the dietetics advice, its a battle.
