Glycemic index of grain amaranth, wheat and rice in NIDDM subjects

1997

A:PS

Three men and 3 women (40-50 years old) with non-insulin dependent diabetes (NIDDM), attending the out-patient department of Osmania General Hospital, Hyderabad, India, received 1 of 5 meals containing 50 g carbohydrate equivalent; rice (control), wheat roti (unleavened bread), amaranth + wheat roti (25:75), amaranth + wheat roti (50:50) and popped amaranth + milk, all with vegetable curry. Postprandial blood glucose was determined at 1, 2 and 3 h after the meal. The glycaemic index (GI) of amaranth-wheat (25:75), wheat, rice, amaranth-wheat (50:50) and popped amaranth in milk was 65.6, 65.7, 69.2, 75.5 and 97.3%, respectively. It is concluded that 25:75 amaranth-wheat, wheat and rice have a low GI, 50:50 amaranth-wheat has a medium GI, and popped amaranth in milk has a high GI. Amaranth alone cannot be suggested for use by NIDDM patients, but its partial substitution for wheat flour can increase the amino acids, Ca and Fe content of foods.
