Detailed Description:

Metabolic syndrome (MetS), a constellation of metabolic abnormalities including central obesity, dyslipidemia, elevated blood pressure and hyperglycemia, is associated with the development of type 2 diabetes and CVD. It has become one of the major public health challenges in China due to rapidly nutrition transition and the nature of obesity epidemic. Treatment of MetS in China is very important for the prevention of the epidemic of its consequences (such as CVD and type 2 diabetes).

Compelling evidence from recent human studies has demonstrated that diet and lifestyle modifications are effective means in MetS management. Flaxseed is a complex food source containing high amounts of alpha-linolenic acid (ALA) - an omega-3 fatty acid - as well as fiber, lignan precursors and other substances that may have an impact on our health. Therefore, the aim of this study is to investigate the effect of flaxseed supplementation on the management of MetS in adult Chinese men and women in a randomized, controlled clinical trial. A total of 200 participants with MetS (defined by IDF criteria) will be randomly assigned to a flaxseed-supplemented diet (30 grams/day) or an isocaloric control diet for 12 weeks. Effects of flaxseed supplementation will be evaluated by measuring metabolic profile (BMI, blood pressure, total cholesterol, triglyceride, LDL-C and HDL-C, fasting glucose and insulin, HbA1C), inflammatory markers (CRP and IL-6), markers of endothelial function (E-selectin, ICAM-1 and VCAM-1), and fatty acid profile.


Ages Eligible for Study:   35 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The International Diabetes Federation (IDF) criteria for the diagnosis of the MetS will be used. MetS will be defined with central obesity (defined as waist circumference ≥ 80 cm for women or ≥ 90 cm for men) plus any two of the following four factors:

    • Raised triglycerides level: ≥ 150 mg/dL (1.7 mmol/L), or specific treatment for this lipid abnormality;
    • Reduced HDL cholesterol: < 40 mg/dL (1.0 mmol/L) in males and < 50 mg/dL (1.3 mmol/L) in females, or specific treatment for this lipid abnormality;
    • Elevated blood pressure (BP): systolic BP ≥ 130 or diastolic BP ≥ 85 mm Hg, or treatment of previously diagnosed hypertension;
    • Increased fasting plasma glucose (FPG): ≥ 100 mg/dL (5.6 mmol/L), or previously diagnosed type 2 diabetes.
  • Being able to comply with the specified feeding conditions
  • Being able to eat flaxseeds
  • Being between the ages of 35 and 60 years

Exclusion Criteria:

  • Pregnancy or lactation
  • Use of insulin
  • Severe kidney disease
  • Cardiovascular diseases, stroke, cancer and psychological disorders
  • Flaxseed allergies or frequently eating flaxseeds or sesame (>90 grams/week)
  • Drug or alcohol abuse.
