Abstract
Objective: To assess effectiveness of active dietary education program including flaxseed oil intake in improving MetS.
Methods: Subjects were 18 specific health examination patients, (males 4, females 5)of whom 9 were assigned to an intervention group, IG (Active Program), and the remaining 9 (all males) to a control group, CG (e-mail Program). We conducted the intervention from November 2009 - March 2010 with a clinical examination and dietary survey of the groups at baseline and 2 and 4 months after intervention. Dietary intake was 1,800±150 kcal/day with flaxseed oil (ALA, 2.14g/day) until 2 months after intervention and without until 4 months, and exercise. The IG received 8 sessions of lectures/cooking instruction. The CG received information 4 times by e-mail.
Results: After 2 months, in the IG, there were significant decreases in CW and SBP (p<0.05 each) and DBP and numbers of MetS risk factors (p<0.01 each) compared with the CG. The IG had significant decrease in lauric acid (p<0.05) and there were significant decreases in total energy, protein and carbohydrate intake (p<0.05 each) and an increase in soybean energy intake (p<0.05). After 4 months, the IG had significant decreases in SBP (p<0.05) and DBP (p<0.01) compared with CG; In the IG, there were significant decreases in lauric acid (p<0.01) and palmitic acid (p<0.05), and increases in oleic acid, DHA and DTA (p<0.05 each). There were also significant decreases in total energy and carbohydrate intake (p<0.05 each).
Conclusion: Our dietary education program including flaxseed oil intake was effective in improving MetS.
