Day 040 - 21 Oct 94 - Page 31
1 reason now, Dr. Millstone.
2 A. Because I believe that for reasons that I think
3 I outlined either yesterday or the day before, conceivably
4 both, I believe there are very serious shortcomings in
5 those studies which report estimates of the frequency of
6 adverse reactions to food additives.
7
8 I would estimate that and I have seen some evidence
9 particularly from a Dr. Ward at the University of Surrey,
10 suggesting that something in the order of 80 per cent of
11 people who show intolerance to additives, also show
12 intolerance to some foods.
13
14 Therefore, if one is to properly estimate the true
15 incidence of adverse reactions, acute adverse reactions, to
16 additives, it is necessary to put them on an elimination
17 diet which excludes not merely -- prior to their challenge
18 -- the additives to which they may react adversely, but
19 also foods to which they may react adversely. My reading
20 of particularly the Young and Lessof study (upon which the
21 Department of Health and the Ministry of Ag. Fish and Food
22 place considerable reliance) is that they fail to take that
23 elementary, methodological precaution.
24
25 Therefore, I believe that the signal was lost in the noise
26 and that they, therefore, significantly underestimate the
27 true incidence. I have also indicated in answer to
28 previous questions that other studies which have attempted
29 to estimate the incidence of intolerance to additives have
30 been flawed for a variety of reasons, including
31 systematically excluding from their sample precisely the
32 kinds of people most likely to suffer intolerance, such as
33 young children or people who have been diagnosed as
34 suffering from allergies.
35
36 I was given to understand by his Lordship that I would be
37 invited, or given an opportunity, to prepare another
38 document on the question of the incidence -- estimates of
39 the incidence of these reactions, and I would be able and
40 willing to do so and can there spell out my reasons in some
41 detail, itemising the particular studies involved.
42
43 MR. RAMPTON: If you are going to do that, Dr. Millstone, turn
44 over the page, please, to the section headed: "Tracking
45 down the problem". Do you have that?
46 A. Yes.
47
48 Q. That section has three columns, the first column has two
49 black blobs. Under the second blob it says: "You may be
50 asked to avoid a single suspect food for a few weeks. In
51 theory, any food can cause allergy, but several studies
52 show that by far the most common culprits are milk, eggs,
53 fish, shellfish, nuts and wheat".
54
55 Can you, please, if you are going to inform us of your
56 views about incidence, comparative incidence, lay hands on
57 as many such studies as you are able? That is a request,
58 not a question.
59 A. Yes, I can do that, but I would say that the only
60 studies that I have made a point of gathering are studies
