     1   MR. MORRIS:  So when we say it is lower 1600 mg ---- What does
              the RNI in that case -----
     2
         MR. JUSTICE BELL:   Although I do not want to be unhelpful,
     3        basically you have to reserve your cross-examination for
              the end.
     4
         MR. MORRIS:  I understand that.
     5
         MR. JUSTICE BELL:   Otherwise it becomes scrappy when it says
     6         'enough or more than enough', 'more than enough' is not
              pejorative in that as I understand it in that definition,
     7        in order to be confident of getting enough, you may well
              in fact take on board more than you need?
     8        A.  That is right.
 
     9   Q.   So there is no suggestion that the RNI is too much?
              A.  No.
    10
         Q.   As I understand it.
    11        A.  No, that would be my understanding as well.
 
    12   MR. RAMPTON:  Of course, I take it that the need will vary from
              person to person?
    13        A.  Absolutely.
 
    14   Q.   You must not regard this as a figure setting statement?
              A.  Again, it will also depend on the circumstances
    15        because if you are in a particularly hot climate then the
              salt loss would be greater so the requirement would be
    16        greater.
 
    17   MR. JUSTICE BELL:   Can I just ask this last question then we
              will break off until two o'clock.  25.4 deals with
    18        excretion as well as intake.  With salt is excretion
              related in part to intake? What I am really getting at is:
    19        Does the body have a mechanism for excreting more salt if
              too much salt is taken in?
    20        A.  Yes.  Again, that would be my understanding of how it
              works. I am not an expert in this particular field, but
    21        certainly if the kidneys are functioning all right, they
              will get rid of the excess.

    23                              (Short Adjournment)
 
    24                                           2.00 p.m..
 
    25   MR. JUSTICE BELL:  As a matter of general interest perhaps,
              more than specific interest, I notice from (vi) glossary 
    26        of terms that honey is extrinsic sugar as, indeed, is 
              lactose; (vi) the beginning of that glossary, table sugar 
    27        obviously, because the lactose is not within the cell wall
              of the food.  That is the technical distinction, is it?
    28        A.  That is right, but the lactose is not included in the
              recommendations for extrinsic sugars.  It talks about
    29        non-milk.
 
    30   MR. JUSTICE BELL:  There is a specific reference in the
              paragraph.
