1 the risk of diseases such -----
3 Q. Might prevent or reduce the risk?
4 A. They are not saying ----.
6 Q. An example of that is the one we were reading before, the
7 US National Academy. "It is important to remember that
8 although diet is an important contributory factor to these
9 diseases". Would you say that is a bit strong or that is
10 an important contributory factor?
11 A. I think, certainly as far as coronary artery disease
12 is concerned, diet is important.
14 Q. But it says "to these diseases", so presumably all those
16 A. Well, you know, I would agree with some of it but not
17 as far as cancer is concerned, because I do not believe we
18 have the evidence to support that.
20 Q. So would you say therefore that that statement ----?
21 A. They are talking about obesity and we know the
22 influence that obesity has on the outlook of patients with
23 cancer, so in that sense it is important.
25 Q. So you can say that diet is linked to cancer through
26 obesity but not necessarily through other ----?
27 A. There is a linkage, but not necessarily in terms of
30 Q. Right.
31 A. I mean, it seems logical to assume that aspects of our
32 diet are involved in the causation of certain illnesses.
34 Q. Yes.
35 A. But my argument ----.
37 Q. Including cancer?
38 A. Including cancer, but my argument is we do not have
39 the scientific evidence to support that at the moment. We
40 have conflicting evidence, some of which suggests that
41 there is a relationship between certain items in the diet
42 and cancer, and equally convincing evidence from other
43 studies which fail to demonstrate that. As anything in
44 medicine, one has to have consistency of finding and
45 reproduceability of the studies before one can say, "yes,
46 there is a definite linkage here".
48 Q. I am going to come later on to seeing whether these
49 recommendations and your position is right or not right.
50 What I am trying to look at is the advice that is being
51 given or recommendations that are being given by bodies.
52 A. I have already agreed that the advice that is being
53 given is very sensible in the light of our current
56 MR. JUSTICE BELL: Is there a specific reason why you are not
57 asking the witness to look at this document?
59 MR. MORRIS: I will show it to him in a minute. I just wanted
60 to not colour any possible professional response.
