Almond Consumption May Lower 24-Hour Insulin Secretion in

Hyperlipidemic Men and Women

Reference: " Effect of almonds on insulin secretion and insulin

resistance in nondiabetic hyperlipidemic subjects: a randomized

controlled crossover trial, " DJ, Singer W, et al, Metabolism,

2008 57(7): 882-887. (Address: Faculty of Medicine, Department of

Nutritional Sciences, University of Toronto, Toronto, Ontario, Canada

M5S 3E2 ).

Summary: In a randomized, crossover study involving 27 hyperlipidemic

men and women, results indicate that consumption of almonds may reduce

24-hour insulin secretion. Using a crossover design, the subjects were

randomized to consume full-dose almonds (73 g/d), half-dose almonds +

half-dose muffins, and full-dose muffins, each for one month. After

adjusting for urinary creatinine output, 24-hour urinary C-peptide

output (marker of 24-hour insulin secretion) significantly reduced after

the full-dose and half-dose almonds intervention, compared with the

control intervention (full-dose muffins). Thus, the authors of this

study conclude, " reductions in 24-hour insulin secretion appear to be a

further metabolic advantage of nuts that in the longer term may help to

explain the association of nut consumption with reduced CHD risk. "
