         MR. RAMPTON:  My Lord, yes.  The actual excluded group is
     2        non-milk extrinsic sugar; is that not right?
              A.  Yes, that is right.
     3
         Q.   Non-milk.  I was wrong in suggesting honey, you were
     4        uncertain and his Lordship has corrected it?
              A.  Absolutely.
     5
         MR. JUSTICE BELL:  That is 553.  Yes, thank you.
     6
         MR. RAMPTON:  Yes.  May we now turn, Professor Wheelock, to
     7        fibre, but before I do that, there is a question his
              Lordship raised yesterday which I wonder if you can answer
     8        which is this:  Where one sees what are variously called
              recommended daily allowances or ADIs which are acceptable
     9        daily intakes, or DRVs, for a certain quantity of a
              substance per day, is one looking at a diet over a week or
    10        a year or a lifetime?  What is one actually looking at
              when one sees that recommended figure on a daily basis?
    11        A.  It is impossible to be absolutely categoric, but what
              I could say is that we are not just looking at one day in
    12        isolation.  It is more likely to be over a week or over a
              month.
    13
         Q.   Take a week.  If I have, let us say, in excess of my DRV
    14        for saturated fat in one day, can I balance that by eating
              less than my DRV in the next day or two?
    15        A.  In my view, yes.
 
    16   Q.   Can we then go to dietary fibre, page 61 of this grey
              volume, chapter 4, described by the learned gentlemen as
    17        non-starch polysaccharides.  I will read the
              introduction:  "In considering the nutritional role of
    18        what is known as 'dietary fibre' the Panel was hindered in
              making a sound scientific assessment of the literature
    19        because of imprecision in its terminology.  Over the years
              a variety of both of definitions and of analytical
    20        techniques has been used which are not necessarily
              comparable.  The Panel supported the proposition by others
    21        that the term 'dietary fibre' should become obsolete and
              decided for reasons given below, that specific evidence in
    22        relation to dietary non-starch polysaccharides (NSP) would
              be reviewed.  NSP are the major fraction of 'dietary
    23        fibre' whatever definition is used, are chemically
              identifiable and can be measured with reasonable
    24        precision.  Where possible the physical properties of NSP
              have also been taken been taken into account."
    25
              Then if you drop your eye down to the bottom of 4.2.1 you 
    26        see the sentence:  "Non-starch polysaccharides are the 
              main component of the plant cell wall and the best single 
    27        index of the dietary fibre concept".  Professor Wheelock,
              as an expression of the state of learning in 1991, do you
    28        agree with those observations?
              A.  Yes, I do.
    29
         Q.   Thank you.  Then can we turn over the page where we see a
    30        table, page 62, table 4.1, and we see where we might find
              which kinds of polysaccharides, do we not?
