I have just heard James Whale interviewing a nutrition specialist - who said that recent studies show absolutely no link between fat and heart problems. She did say that it mattered what you cooked in fat and what sort of fat but didn't elaborate further.
James Whale mentioned that last time she had been on his show , a cardiologist had rung in to say that she was peddling seriously harmful misinformation and that fats were really bad. She replied that obviously, he wasn't reading up to date studies, papers etc.
I was delighted - the more I hear this sort of thing the better I feel about the whole "movement"!!
