Glycemic Index of Lentils

Lentils are the unsung heroes of the nutrition world. Inexpensive and versatile, lentils are rich in protein and fiber but low in fat. They are relatively low in calories and a good source of vitamins and minerals. As a low glycemic index, or GI, food, lentils are also an ideal source of slow-burning energy that may have additional benefits to human health, says the University of Sydney, Australia 1.

Glycemic Index

The glycemic index, or GI, is a ranking of carbohydrate-rich foods on a scale of 0 to 100 according to the degree they influence blood glucose levels after consumption 1. High GI foods have a score of 70 or greater and cause a quick rise in blood glucose. Low GI foods are ranked 55 or lower due to their slower release of energy. A diet based on low glycemic index foods may help with weight control and heart health, says a 2007 Cochrane Intervention Review.

Lentils can be bought dried or canned. Supermarkets sell lentils but an ethnic market or health-food store may have a greater selection from which to choose. Dried lentils are sold in prepackaged bags or in the bulk-bin area. Once purchased, dried lentils keep indefinitely in an airtight container if kept in a cool, dry place. Canned lentils are more convenient because they do not require any cooking before use, but they contain more sodium than their dried counterparts.
