To evaluate changes in serum fatty acids, metabolic profile and inflammation markers after a dietary intervention of 15g of walnuts and 15g of almonds for 8 weeks in obese subjects,
Patients and Methods:
We studied a total of 48 sedentary obese grade I subjects (13 men and 35 women). Anthropometric measures, body composition, serum glucose, lipid profile, insulin, lipocalina-2, high sensitivity C-reactive protein (hsCRP), adiponectin, and fatty acids profile were analyzed at the baseline and after dietary intervention.
The adiponectin (30.4%, p = 0.007), and lipocalin-2 concentrations (17.9%, p = 0.014), and total Polyunsaturated Fatty Acids (PUFAs) percentage (1.6% p = 0.040) significantly increased after the intervention; particularly the eicosapentaenoic acid and docosahexaenoic acid percentages were increased marginally. A significant decrease in saturated fatty acids levels (3%, p = 0.001), in particular the C:14, C:16, in total cholesterol (6.7%, p = 0.01), LDL (11.4%, p = 0.002) levels, and in all adiposity measures (weight, waist circumference, hip circumference, BMI and fat mass, p < 0.0001) was found. The effect size was large for all adiposity measures, except for BMI as well as for adiponectin which was moderate.
The intake of almonds and walnuts to short-time may improve significantly the metabolic profile and decrease adiposity.
