APPENDIX IV: RELATED FOODS
The relevance of food relationships to food sensitivity is explained on p255. Briefly, a person who is sensitive to one plant food (eg oranges) may react badly to other foods from related plants (eg lemons and grapefruit). The same also goes for foods from animal sources?
In the past, a great deal of emphasis has been placed on ‘food families’ – by those treating food intolerance. These doctors have automatically looked at the taxonomic family of plants and animals to predict when cross-reactions are likely to occur.
But the family is just one sort of group in taxonomy – the science of biological classification. A closer look at the cross-reactions shown by patients suggests that the family is not always the most relevant group to consider. Sometimes we need to consider higher or lower levels of classification. The over-emphasis on food families can create problems. For example, it can lead food-sensitive people to eat too much of some potentially troublesome foods (eg fish) while avoiding many plant foods unecessarily.
