To assess the hypoglycemic effect of the nopal Opuntia streptacantha
Lemaire (O. streptacantha Lem.), three groups of patients with
non-insulin-dependent diabetes mellitus (NIDDM) were studied. Group one (16
patients) ingested 500 g of broiled nopal stems. Group 2 (10 patients)
received only 400 ml of water as a control test. Three tests were performed
on group 3 (6 patients): one with nopal, a second with water, and a third
with ingestion of 500 g broiled squash. Serum glucose and insulin levels
were measured at 0, 60, 120, and 180 min. After the intake of O.
streptacantha Lem., serum glucose and serum insulin levels decreased
significantly in groups 1 and 3, whereas no similar changes were noticed in
group 2. The mean reduction of glucose reached 17.6 +/- 2.2% of basal
values at 180 min in group 1 and 16.2 +/- 1.8% in group 3; the reduction of
serum insulin at 180 min reached 50.2 +/- 8.0% in group 1 and 40.3 +/-
12.4% in group 3. This study shows that the stems of O. streptacantha Lem.
cause a hypoglycemic effect in patients with NIDDM. The mechanism of this
effect is unknown, but an increased insulin sensitivity is suggested.
