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. Line 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, phenethylamine, 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 30 Hyperactive. Other researchers have had
mixed results when testing whether the diet is effective.

Reading Comprehension Passage 4
Lichens, of which more than
twenty thousand
species have been named, are complex associations
between certain algae. The lichen itself is not
an organism: rather it is the morphological and biochemical
product of the association. Neither a fungus
nor an alga alone can produce lichen.
The intimate relationship
between these two
living components of lichen was once erroneously
though to represent mutualism. In mutual relationships,
both participants benefit. With lichens, however,
it appears the fungus actually parasitizes the algae.
This is one of the conclusions drawn from experiments
in which the two components of lichens were separated
and grown apart.
In nature, lichen fungi may encounter and
grow around saveral kinds of algae. Some types of
algae the fungi may kill; other types it may reject.
Lichen algae are autotrophic, meaning they make their
own food through photosynthesis. Lichen fungi are
heterotrophic, meaning they depend upon the algae
within the lichen to supply their food. Up to ninety
percent of than food made by the green alga cell is
transferred to the fungus. What, if anything, the fungus
contributes to the association is not well understood.
Lichens are hardly. The grow in many
habitats
and are often pioneers in hostile environments
where few other organisms can flourish.
They have been known to grow
endolithically, having been discovered thriving inside
of rocks in Antartica. Lichen help reduce erosion by
stabilizing soil. Saveral kinds of insects glue lichens to
their exoskeletons for camouflage.
Many species of birds use lichens as building
materials for nests. Human have used lichens for
dyes and antibiotics.
