4 MS. STEEL: Is that in the references?
5 A. Yes, it is in the references cited here. It is fair
6 to say those figures have been discussed and quoted
7 numerous times in the research literature since that time.

9 MR. MORRIS: When we looked at the Grey Book -- this was read
10 out -- which is the British Dietary Reference Values for
11 Food and Energy?
12 A. Yes, I have it in front of me.
13
14 Q. On page 52, under the section on cancer, very first line,
15 it is called Dietary fat and aetiology of cancer. People
16 do not need to go to this now. I will just read it out.
17 "Dietary fat and aetiology of cancer. A number of
18 mechanisms whereby fat could be involved in cancer
19 promotion has been suggested". Then it went through
20 them. Is promotion of cancer considered to come under the
21 heading of causation?
22 A. Yes.
23
24 Q. So if something is promotive then it can be termed
25 "causal"?
26 A. Yes, if the cancer is not promoted, if the growth of
27 the cancer cell is not promoted, the cancer never
28 manifests and would never be diagnosed.
29
30 Q. Also Mr. Rampton drew the court's attention to the World
31 Health Organisation 1990 report on chronic diseases,
32 page 92. Again I do not think you have to get it out, but
33 I will just read out what he read out it was under the
34 heading of 4.1.3: "Intakes of saturated fatty acids".
35 The first paragraph in that section goes: "These fatty
36 acids", meaning saturated fatty acids, "may also be
37 specifically involved in promoting cancers", my emphasis,
38 "particularly of the colon and breast, although the
39 evidence remains inconsistent. The main justification for
40 limiting saturated fatty acid intake should therefore be
41 the prevention of coronary heart disease". Now I will
42 just ask you that stress was put upon that, but that does
43 not, in your opinion, refer to total fat or fat in
44 general? When it says: "The main justification for
45 limiting saturated fatty acid intake should therefore be
46 the prevention of coronary heart disease"?
47 A. You are quite correct.
48
49 Q. It does not follow, therefore, that is the main
50 justification for limiting fat?
51 A. You are quite correct and -----
52
53 Q. It is, is it not, that saturated fatty acids is the main
54 implication for coronary heart disease?
55 A. That is an extremely important distinction because the
56 saturated fat is the portion which stimulates the liver to
57 manufacture increasing amounts of cholesterol; yes, you
58 are quite correct. The emphasis is somewhat different
59 when it comes to cancer.
