glucagon-like-peptide-2 and Metabolic-Syndrome

A multifunctional diet (MFD) was previously shown to reduce blood lipids, CRP and blood pressure in a 4-week intervention under weight-maintenance conditions. Here, MFD effects were evaluated in an 8-week intervention with no restriction for weight changes.. Healthy subjects consumed MFD (23 subjects) or a control diet (CD) devoid of the functional components (24 subjects) in a "free-living" randomized controlled experiment. MFD included several functional concepts: low-glycemic-impact meals, antioxidant-rich foods, oily fish, viscous dietary fibers, soybean and whole barley kernel products, almonds and plant stanols. Measured outcomes were fasting blood values of lipids, glucose, insulin, GGT, CRP, HbA1c, PAI-1, GLP-1, GLP-2, body weight, blood pressure and breath hydrogen.. At baseline, participants were 51-72 years old, with BMI between 25 and 34 and fasting glycemia  ≤ 6.1 mmol/L. Consumption of both diets resulted in similar weight loss after 8 weeks (-4 %; P  <  0.001). Compared to baseline, consumption of MFD reduced total serum cholesterol (-26 %; P  <  0.0001), LDL cholesterol (-35 %; P  <  0.0001), triglycerides (-16 %; P  < 0.05), LDL/HDL (-27 %; P  <  0.0001) and ApoB/ApoA1 (-15 %; P  <  0.0001). There were important net differences between diets, which remained significant after adjustment for body weight. Reduced systolic blood pressure, circulating GGT, HbA1c and insulin concentrations were observed with both MFD and CD with no difference between diets. The Reynolds cardiovascular risk score was decreased by 36 % (P  <  0.0001) with MFD. MFD increased breath hydrogen levels (120 %; P  <  0.05).. Consumption of MFD decreased blood lipids and improved several other aspects of the cardiometabolic risk profile. This effect was not dependent on weight loss.
