     1        recognised that fried meat contains carcinogenic
     2        heterocyclic amines.

     4   MR JUSTICE BELL:  I will not try and get that down.  Give me the
     5        reference for it.

     7   MS. STEEL:   Day 34, page 38.  It is H-E-T-E-R-O-C-Y-C-L-I-C and
     8        another word, A-M-I-N-E-S.

    10        The author of the report considered that a preference for
    11        brown meat can be related to colorectal cancer.
    12        Dr. Barnard also referred to the National Cancer Institute
    13        booklet which stated that considerable evidence linked a
    14        high fat diet to a high incidence of colon cancer.  Day 34,
    15        page 41.  And in a National Research Council publication in
    16        1982 it was accepted that experimental evidence was
    17        suggestive for a causal link between high fat intake and
    18        cancer.  That was day 34, page 46.
    19
    20        Dr. Barnard agreed with the conclusions of the World Health
    21        Organisation report in 1990.  I will not go through them
    22        again, because we have been through them about three times
    23        with all the various other witnesses who agreed with the
    24        conclusions, but the reference for that is day 34, pages 49
    25        to 52.
    26
    27        In cross-examination, Dr. Barnard stated that 35 to 50
    28        percent of all cancers were due to diet, and that was
    29        responsible for more cancer deaths than genetics.  That was
    30        day 35, page 10.  He agreed that there was a role for diet
    31        in both initiation and promotion of cancer though he
    32        thought that promotion was probably more decisive, but, I
    33        mean, that does not particularly matter to us anyway.  That
    34        was day 35, page 14.  That was colon cancer.
    35
    36        Dr. Barnard's interpretation of the document from the
    37        National Cancer Institute in 1991 was that there was
    38        abundant evidence to lead to the conclusion that a diet
    39        high in fat and meat, low in fibre, contributes to a risk
    40        of colon cancer, and the document asserts a cause and
    41        effect relationship, the only uncertainty being the sort of
    42        exact mechanism of how diet increased the risk.  He
    43        believed that he was supported by the Surgeon General's
    44        interpretation -----
    45
    46   MR. JUSTICE BELL:   Do you have a reference for that?
    47
    48   MS. STEEL:   Sorry, day 35, page 18.
    49
    50   MR JUSTICE BELL:  Yes.
    51
    52   MS. STEEL:   He believed he was supported by the Surgeon
    53        General's interpretation of the same document.  That was
    54        day 35, page 19, and he refers to that report saying that
    55        the best estimate for factors for cancer under diet, the
    56        best estimate, was 35 percent.  When he was cross-examined
    57        about the use of the words such as 'may' and 'might' in
    58        relation to the strength of the link between diet and
    59        cancer, Dr. Barnard used as an analogy the research on
    60        smoking and lung cancer and said that smoking may cause
