1 A. No, but I do know that exercise is -----
2
3 Q. That is a bit lighthearted. These are quite serious
4 considerations, are they not, Professor Campbell, when one
5 is looking at the possible causes of degenerative disease
6 via, perhaps, the route of obesity or high serum
7 cholesterol level?
8 A. I do not know that exercise promotes a lowering of
9 total cholesterol. It may, in fact, actually increase the
10 amount of so-called good cholesterol; there is some
11 evidence of that. But I draw my conclusions on exercise,
12 primarily on the basis of a large number of studies that
13 have specifically isolated the effect of exercise compared
14 to diet. Exercise is certainly helpful; there is no
15 question about that. There is some modest reduction of
16 cancer risk, particularly of cancer of the colon; but with
17 the other cancers, I am not sure that this much has been
18 shown.

22 MR. RAMPTON: My Lord, yes.

25
26 MR. RAMPTON: Professor Campbell, I hope you have open in front
27 of you your paper about the Chinese project, the 1994
28 paper. Have you?
29 A. Yes, I do.
30
31 Q. Could I ask you to look at the bottom of the right-hand
32 column on the second page, which is page 1154S?
33 A. Yes.
34
35 Q. It is not a complete paragraph; it is the one which begins
36 "Junshi Chen". Do you see that one?
37 A. Yes, I do.
38
39 Q. I will not read it out. I am sure you are very familiar
40 with it, anyway. But am I right that what, in fact, you
41 did, at that stage at least, was to measure diet as at
42 1983/84 ---
43 A. Yes.
44
45 Q. -- and make a correlation of those measurements with
46 mortality rates for 1973 to 1975?
47 A. Yes.
48
49 Q. These being degenerative diseases of long to longish
50 gestation?
51 A. Yes.
52
53 Q. In effect, what you have had to assume -- and I am not for
54 the moment questioning the assumption -- but, in effect,
55 what you have had to assume is that the diets which were
56 measured in 1983/84 were similar to, if not the same as,
57 the diets which were being eaten in the 1950s?
58 A. Yes.
59
60 Q. Is that right?
