Lime-treated corn husks lower plasma LDL-cholesterol in normal and hypercholesterolemic adult men from the Northern part of Mexico

Lime treated corn husks (LTCH), a by product of tortilla manufacturing containing 5% of soluble fiber was assessed for its potential hypocholesterolemic properties in a free living population from the Northern part of Mexico. The fiber intake of participants was increased by supplementing their diet with cookies containig 45% LTCH. Normal subjects (n = 11) with plasma cholesterol less than 220 mg/dL and hypercholesterolemic individuals (n = 12) with plasma cholesterol higher than 220 mg/dL participated in the study. A decrease of 11-15% total and 25% LDL cholesterol was observed after 6 weeks of supplementation resulting in an overall improved LDL/HDL ratio 40 to 50% lower(P <0.01)in both normal and hypercholesterolemic subjects. Both groups consumed equal amounts of LTCH per week and individuals had an excellent compliance and good acceptability of the product. Neither group changed their dietary habits during the time of the experiment as determined by three day dietary records. We conclude that LTCH supplements are suitable to increase fiber intake and reduce plasma LDL cholesterol in healthy and hypercholesterolemic subjects in this population.
