Sweet Fruit
Pears are fruits produced and consumed around the world, growing on a tree and harvested in the Northern Hemisphere in late summer into October.
The pear tree and shrub are a species of genus Pyrus, in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees.
The tree is medium-sized and native to coastal and mildly temperate regions of Europe, North Africa, and Asia. Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture.
About 3000 known varieties of pears are grown worldwide, which vary in both shape and taste. The fruit is consumed fresh, canned, as juice, or dried.
The pear is native to coastal and mildly temperate regions of the Old World, from Western Europe and North Africa east across Asia. It is a medium-sized tree, reaching 10–17 m (33–56 ft) tall, often with a tall, narrow crown; a few species are shrubby.
The leaves are alternately arranged, simple, 2–12 cm (1–4+1⁄2 in) long, glossy green on some species, densely silvery-hairy in some others; leaf shape varies from broad oval to narrow lanceolate. Most pears are deciduous, but one or two species in Southeast Asia are evergreen. Most are cold-hardy, withstanding temperatures as low as −25 to −40 °C (−13 to −40 °F) in winter, except for the evergreen species, which only tolerate temperatures down to about −15 °C (5 °F).
We naturally have sugar in the bloodstream that provides energy to every body cell. Healthy levels of this sugar, glucose, are maintained by insulin, a hormone secreted when blood sugar rises too high. Type 2 diabetes happens when your body doesn’t make enough insulin or your body’s cells don’t respond normally to insulin, called insulin resistance. This causes high blood sugar and immediately starts to starve cells of energy. Over time, high blood sugar damages sensitive tissues, such as those in the extremities, eyes, and kidneys.
Sometimes people think that since fruit naturally contains sugar, eating fruit is not appropriate for managing diabetes. This is not true! Fruit is full of vitamins, minerals, water, and fiber – all important nutrients – and most fruits are considered low GI foods. Indeed, foods high in fiber, such as pears, taste sweet without having the deleterious effect of spiking blood sugar.
Pears come in many different varieties. Bartlett, Bosc, and D’Anjou pears are among the most popular, but around 100 types are grown worldwide.
Pears offer many beneficial plant compounds that give these fruits their different hues. For instance, anthocyanins lend a ruby-red hue to some pears. These compounds may improve heart health and strengthen blood vessels.
Though specific research on pear anthocyanins is needed, numerous population studies suggest that a high intake of anthocyanin-rich foods like berries is associated with a reduced risk of heart disease. Pears with green skin feature lutein and zeaxanthin, two compounds necessary to keep your vision sharp, especially as you age.
Again, many of these beneficial plant compounds are concentrated in the skin.
