Carbohydrates
Bosc pears are carbohydrate-rich, as each medium, 179-gram pear contains about 29 grams of carbohydrates. That amount is twice what a slice of bread provides, so Bosc pears can be a good source of pre-exercise energy. Carbohydrates are your body's primary source of fuel.
Fiber
Bosc pears are rich in one particular type of carbohydrate -- dietary fiber. Each medium pear contains about 5.5 grams of this nutrient, which is essential for overall health and can be helpful for dieting. Dietary fiber provides feelings of fullness and also keeps your blood sugar levels stable, promotes healthy digestion and may aid in cholesterol management.
Protein
Bosc pears are not a good source of protein, because a medium pear provides just .64 grams of this nutrient. Your body uses protein to build and repair vital tissues and cells, so consuming adequate amounts is essential.
Minerals and Vitamins
Bosc pears are not particularly robust sources of vitamins and minerals. However, each medium pear does contain 5 milligrams of vitamin C, 18 milligrams of calcium and 218 milligrams of potassium.
