Fresh fruits such as pears, peaches and pineapples offer lots of nutritional value. As part of a well-balanced diet, they provide the nutrients your body needes to function, and might even fight disease. Women that are 19 to 30 years of age should eat about 2 cups of fruit per day while women that are 31 and over should consume 1 ½ cups per day, according to USDA MyPlate dietary guidelines.
Calories and Fat
Like most fruits, peaches, pears and pineapples are naturally low in calories and fat. One medium peach contains 60 calories, and one serving of pineapple -- two 3-inch slices -- contains 50 calories. Pears contain more calories than peaches and pineapples, with 100 calories per medium pear. None of these fruits contain a significant amount of fat.
Pears have a higher total carbohydrate content than peaches and pineapples, and they provide significantly more dietary fiber. One medium pear contains 26 grams of carbohydrates, including 6 grams of dietary fiber and 16 grams of sugar. One medium peach contains 15 grams of carbohydrates, including 2 grams of dietary fiber and 13 grams of sugar. One serving of pineapple contains 13 grams of carbohydrates, including 1 gram of dietary fiber and 10 grams of sugar. Dietary fiber plays an important role in digestive health and helps to provide a lasting feeling of fullness. The Harvard School of Public Health recommends that adults get at least 20 to 30 grams of fiber per day.
Peaches, pears and pineapples all provide some vitamin C, but pineapples have significantly more than peaches and pears. One serving of pineapple provides 50 percent of the recommended daily vitamin C intake, while one medium peach has only 15 percent. One medium pear provides only 10 percent. This vitamin C boosts collagen production -- a process that keeps your tissues strong -- and plays a role in brain health.
Peaches contain more potassium than pears and pineapples, with 230 milligrams per serving. One medium pear provides 190 milligrams of potassium, and one serving of pineapple has 120 milligrams. Getting enough potassium in your diet nourishes your nerves and muscles -- it allows nerve cells to communicate with each other, as well as send signals to your muscle fibers. It also regulates your blood pressure and promotes cardiovascular health.
