     1        situation in any respect.  Because what we are looking at
     2        is the contribution the saturated fats might make in some
     3        to the risk of heart disease.  I think that what one is
     4        saying here is that a single meal will provide a certain
     5        amount of saturated fats and can you, from that, say if
     6        there is a risk associated with either 35 or 70%, can you
     7        say what contribution that might make?  Whether or not it
     8        meets the daily recommendations of this committee or not is
     9        immaterial.
    10
    11   Q.   I think I can make a suggestion, Professor Crawford, in
    12        view of the fact that you have said in your latest paper
    13        that you calculate that the McDonald's meal will contribute
    14        7th or at least 14th of the week's saturated fat intake?
    15        A.   Yes.
    16
    17   Q.   If I can make a suggestion, If you multiply 28 grammes (it
    18        is actually 28.33) by 7 and it is daily intake, you get a
    19        figure of 198, just over?
    20        A.   Yes.
    21
    22   Q.   6.32 grammes, which is the contribution made by this
    23        McDonald's meal that week, is 3 per cent of the total for
    24        that week?
    25        A.   Yes.
    26
    27   Q.   Even if your recommendation is down to 5 per cent, it is
    28        still only a 6 per cent contribution?
    29        A.  Yes but, the point you have to understand is that all
    30        the evidence indicates that these factors are additive.
    31
    32   Q.   You cannot sensibly propose can you, and I must lock horns
    33        with you over this, that a McDonald's meal could
    34        conceivably make a seventh or a fourteenth contribution
    35        towards the weekly saturated fat recommendation?
    36        A.   I am not talking about saturated fat recommendation.
    37        I am talking about the total saturated fat intake and these
    38        are two different phenomenon.  They are two different
    39        animals completely.  The recommendation is what the
    40        committee comes up with.  What you eat in practice is a
    41        totally different phenomenon and what I am saying in the
    42        general framework of what people eat, this is going to make
    43        contribution of X per cent, to their either weekly or daily
    44        intake of saturate fats and therefore based on the
    45        relationships which Ancel Keyes and others have produced
    46        and I am only saying -- I am not trying to make a major
    47        issue out of this as an absolutely accurate and precise
    48        statement because I have said already that if you really
    49        wanted to get into the numbers game, it is going to require
    50        a very large research programme to do it.  But if you want
    51        to look at what people do in practice, then the
    52        contribution within the population of those that are at
    53        risk to mortality from heart disease is in that population,
    54        this is the contributions that you are going to likely find
    55        in practice.  These are very different to recommendations.
    56
    57   Q.   Can you think of any fat that does not contain saturated
    58        fatty acids?
    59        A.   Yes.  I mean, I cannot think of any fat which contains
    60        absolutely no saturated fatty acid, but I can think of
