     1   MR. RAMPTON:  Sorry, cariogenicity.  That is mind set brought
              about by the circumstances of this case.  I apologise.
     2        Cariogenicity.
 
     3   MR. JUSTICE BELL:   In other words, a tendency to rot?
              A.  Yes.
     4
         MR. RAMPTON:  This is really all about dental caries and the
     5        need perhaps for fluoridation, is it not?  "iii: Non-milk
              extrinsic sugars may favour the consumption of food
     6        energy, and in predisposed individuals may have
              undesirable metabolic effects, but are not directly
     7        related to the development of cardiovascular disease,
              essential hypertension, diabetes mellitus or behavioural
     8        abnormalities"
              A.  Yes.
     9
         Q.   That, Professor Wheelock, appears to the layman as a
    10        fairly definite sort of statement.  To the scientist does
              that seem to be categorical as statement?  They say "are
    11        not directly related to development of ----"
              A.  Again, I would accept that as a fair assessment of the
    12        situation.
 
    13   Q.   "iv.  For the obese consumption of non-milk extrinsic
              sugars should be restricted  as part of a general
    14        reduction of dietary energy.  For non- obese adults,
              consumption of non- milk extrinsic sugars up to about 30
    15        per cent of food energy does not carry special metabolic
              risks.
    16
               "v.  Extreme intakes of sucrose above about 200 grammes a
    17        day or about 30 per cent of food energy, may be associated
              in normal adults with elevations of cholesterol, blood
    18        glucose and insulin concentrations all of which may be
              undesirable?
    19        A.  That is getting on for half a pound of sugar.
 
    20   Q.   I was going to ask you: How much ---- Americans would call
              it 'candy'- or boxes of chocolate ---- would one have to
    21        eat to get up to that sort of level.
              A.  200 grammes is getting on for half a pound.
    22
         Q.   That is half pound of sugar in its neat form?
    23        A.  Exactly.  So, I suppose, I mean, some sweets are
              pretty 100 per cent sugar.  If you really gorge yourself
    24        on those then you probably would have a problem under this
              clause.
    25
         Q.   "5.6  Dietary Reference Values 
    26 
               "5.6.1  The Panel did not recommend that intake of 
    27        intrinsic or milk sugars be limited.  They can usefully
              contribute, with starch, to energy requirements not met by
    28        other restricted dietary components".  I do not have to
              ask you anything about that.
    29
         MR. JUSTICE BELL:   Do they have a value in quick energy
    30        replacement?
              A.  Yes, a small amount, something sweet, in the afternoon
