The barefoot runners showed shortening and rising of the arch, indicating increased muscle tone, while the group who ran in shoes had lengthening of their arches. Dr. Feingold first called attention to the presence of salicylates in foods when he treated hyperactivity in children by removing salicylates from their diet. His elimination diet was based on analyses performed at the turn of the century, with methods less accurate than those used today. Because of the current interest in the relationship of salicylates to asthma, Australian researchers analyzed over 300 foods for salicylate content. They report that most fruits contain salicylate, with raisins and prunes containing the most.
Most berries contain significant amounts.
Dried fruits, because of the removal of water, contain relatively high levels when compared with fresh. Bamboo shoots, celery, cabbage, lettuce, dried beans, lentils and dried peas contain low levels of salicylates, as do fresh tomatoes. Curry powder, paprika, thyme, dill powder, tumeric and oregano contain high levels of salicylates. Teas are high in salicylates. Carob and legumes have only small amounts.
