Pear
Pyrus communis
The pear is European and
Asiatic in origin, centering most probably on the region of the
Caucasus, and has been cultivated since well before recorded history.
It is thought that it was spread by the migration of the Aryans
through Europe and India and the remains of wild pears
have been found at Mesolithic sites.
The pear was considered to be
a superior fruit by the Ancients, who much preferred it to the apple.
The Romans raised its cultivation to an art form. In 300BC, Theophrastes
describes pear growing in detail and Pliny
the Elder, the Roman Encyclopaedist lists more pears
than apples in his works. The Chinese, too, held the pear
above the apple. At the time of the Sung Dynasty, (1279AD), there was
just one variety of apple known to the Chinese, but many pears,
and it is the Chinese who claim to have introduced the fruit into
India. Cultivation of different strains was so successful that by the
height of the Medici 200 varieties were available and records from
the Royal Horticultural Society at Kew had
identified more than 700 by 1842.
The pear was included in the
Westward part of the Columbian Exchange, with seeds being shipped out
to the new colony at Massachusetts in 1629. Because they were grown
from seeds, they took on new characteristic in their new environment,
creating quite distinctive American strains.
Pear breeding was at its
height in Western Europe by the 18th century and by 1849 the first
Doyenne de Comice made its appearance on the banks of the Loire in France.
Nutritionally, the pear is
useful for potassium intake, which helps to regulate blood pressure
levels and are a good source of insoluble fibre, which helps regulate
bowel action and may protect against certain forms of cancer. Pear
is also a source of soluble fibre, pectin, and one fruit yields
around 10% of the recommended daily intake for vitamin C. At 40
kcalories per 100g or 70 for the average pear,
it is an ideal snack for weightwatchers - sweet with fructose for
easily utilized energy intake - but still only 38 on the Glycaemic
Index. Dried pears also contain iron and
even higher concentrations of potassium.
Pears are also amongst the
least allergenic of foodstuffs, and so are popular for use in
weaning, exclusion and invalid diets. |
