Chickpeas may influence fatty acid and fiber intake in an ad libitum diet, leading to small improvements in serum lipid profile and glycemic control

Optimal replacement macronutrient/s for dietary saturated fat to reduce cardiovascular disease risk remains controversial. Chickpeas are rich in dietary fiber and polyunsaturated fatty acids. This exploratory study, conducted from September 2004 to May 2005, assessed the effect of incorporating chickpeas in the ad libitum diet of 45 free-living adults. Participants consumed a minimum of 728 g of canned, drained chickpeas per week (the amount in four 300-g cans) as part of their habitual diet for 12 weeks (chickpea phase), followed by 4 weeks of habitual diet without chickpeas (usual phase). In the chickpea phase, mean dietary fiber intake was 6.77 g/day more and mean polyunsaturated fatty acid consumption (as a percentage of total fat) was 2.66% more (both P<0.001), causing the polyunsaturated to saturated fatty acids ratio to change from 0.39 to 0.47 (P=0.045). Serum total cholesterol and low-density lipoprotein cholesterol were 7.7 mg/dL (0.20 mmol/L) and 7.3 mg/dL (0.19 mmol/L) less, respectively, after the chickpea phase (P
