Read the following passage and blacken the letter A, B, C, or D on your answer sheet to indicate
the correct answer to each of the questions.
Scientists do not yet thoroughly understand just how the body of an individual becomes sensitive to a
substance that is harmless or even wholesome for the average person. Milk, wheat, and egg, for
example, rank among the most healthful and widely used foods. Yet these foods can cause persons
sensitive to them to suffer greatly. At first, the body of the individual is not harmed by coming into
contact with the substance. After
a varying interval of time, usually longer than a few weeks, the body
becomes sensitive to it, and an allergy has begun to develop. Sometimes it's hard
to figure out if you
have a food allergy, since it can show up so many different ways.
Your symptoms could be caused by many other problems. You may have rashes, hives, joint pains
mimicking arthritis, headaches, irritability, or depression. The most common
food allergies are to
milk, eggs, seafood, wheat, nuts, seeds, chocolate, oranges, and tomatoes. Many of these allergies will
not develop if these foods are not fed to an infant until her or his intestines mature at around seven
months. Breast milk also tends to be protective. Migraines can be
set off by foods containing
tyramine, phenathylamine, monosodium glutamate, or sodium nitrate.
Common foods which contain
these are chocolate, aged cheeses, sour cream, red wine, pickled herring, chicken livers, avocados,
ripe bananas, cured meats, many Oriental and prepared foods (read the labels!).
Some people have been successful in treating their migraines with supplements of B-vitamins,
particularly B6 and niacin. Children who are hyperactive may benefit from eliminating
food additives,
especially colorings, and foods high in salicylates from their diets. A few of
these are almonds, green
peppers, peaches, tea, grapes. This is the diet made popular by Benjamin Feingold, who has written
the book ―Why your Child is Hyperactive‖. Other researchers have had mixed
results when testing
whether the diet is effective.
