Day 269 - 25 Jun 96 - Page 25
1 I will be happy to discuss in court areas where the
2 evidence of Dr. Arnott and Professor Naismith's evidence
3 appears to conflict with mine.
4
5 Dr. Arnott's evidence:
6 I do not suggest that the common denominator between cancer
7 and heart disease is the adhesion to an antherosclerotic
8 plaque. My hypothesis is that the inducement of cell
9 adhesion which occurs in metastasis and in thrombosis is
10 common to both death from heart disease and the spread of
11 cancer. I stand by this hypothesis and there is now direct
12 evidence as mentioned above to support it. (Cancer cells
13 will migrate through the blood stream or the lymphatic
14 circulation but to take root and grow in another location
15 they have to adhere to the cell wall.
16
17 Thrombosis results from the adhesion and aggregation of
18 platelets and other blood cells to the vascular lining.
19 Both conditions are encouraged by high fat, high saturated
20 fat diets and both are suppressed by the same protective
21 conditions.
22
23 A new study in the New England Journal of Medicine is
24 quoted where no relationship is found when several, small
25 studies were pooled for analysis. There was no distinction
26 given in the paper of the omega 6 or omega 3 fatty acids.
27 Yet they have the opposite effects on cancer development.
28 The British Nutrition Task Force on Unsaturated Fatty Acids
29 describes enough evidence on this subject already in 1992
30 so it should have been taken into account.
31
32 In essence, linoleic acid is required for the growth of the
33 cancer cell up to about 4% of the dietary energy so in this
34 range it acts as an apparent cancer promoter. Arachidonic
35 acid and other long chain omega 6 polyunsaturated fatty
36 acids protect against auto-immune disease and increase
37 super oxide defense activities."
38
39 I cannot say this one.
40 A. Eicosapentaenoic acid.
41
42 Q. All right. "Protects against the --"
43 A. Cachexia.
44
45 Q. Maybe you should read it for me.

47 MR. JUSTICE BELL: Do not worry because the stenographer has a
48 copy of the original statement.
49
50 MS. STEEL: "...of cancer and in general the omega 3 fatty acids
51 appear to protective. The paper quoted by Dr. Arnott
52 refers to polyunsaturated fatty acids as though all of
53 these fatty acids were the same.
54
55 As I mentioned in my previous evidence, cancer research is
56 about the place cardiovascular research was at in 1953.
57 That is observing epidemiological evidence which, despite
58 what Dr. Arnott says, and despite its difficulties, is none
59 the less strong. Research workers in the cardio-vascular
60 field are now testing out the different effects of the
