Are pineapples high in calories?
Brennan J. Robertson's Response
Pineapples are one of the most popular tropical fruits. Native to South America, pineapples contain approximately 74 calories per cup. The bulk of the calories found in pineapple are attributed to carbohydrates, or more specifically fructose (a sugar found in all fruits). As carbohydrates affect insulin levels in the blood, it is important to note that according to the glycemic index the carbohydrates in pineapple have a medium effect on blood sugar levels.
The good news is that pineapple has a high nutritional value (it is an excellent source of vitamin C and manganese and it is a good source of vitamin B1, vitamin B2, copper, and dietary fibre). Therefore, even with a moderate glycemic index it can be part of a healthy diet. Pineapple has minimal fat and sodium and no cholesterol. Some studies suggest that it may be a digestive aid, and a natural anti-inflammatory agent. Further findings suggest pineapples provide antioxidant protection, immune support, and protection against macular degeneration. Additionally, eating more fruit in general is associated with improved insulin sensitivity, better glycemic control, and a reduced risk of cancer and cardiovascular disease.
