About this trial

This is an interventional prevention trial for Metabolic Syndrome focused on measuring flaxseed, lignans, inflammation, Nutrition, enterolactone, enterodiol

Eligibility Criteria

20 Years - 60 Years (Adult)MaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Work in the manufacturing company in the city of Itu-SP.
  • Have at least three of the following cardiovascular risk factors: waist circumference ≥ 90 cm; overweight or obese characterized by BMI ≥ 25 kg/m²; fasting total cholesterol ≥ 200 mg/dL, LDL- cholesterol ≥ 130 mg/dL and HDL-cholesterol < 40 mg/dL, triglycerides ≥ 150 mg/dL; glycemia ≥100 mg/dL; and hypertension characterized by systolic blood pressure ≥140 mm/Hg and/or diastolic blood pressure ≥ 90 mm/Hg.

Flaxssed and low carb group

Arm Description

In the group with 11 volunteers, the control group did no change in normal food intake.

In this group with 14 volunteers, they received 50% carbohydrate, 31% fat, 19% protein and 60 g of flaxseed powder / day during the period of study.

In this group with 13 volunteers, they received 35% carbohydrate, 46% fat, 19% protein and 60g of raw rice powder / day during the period of study.

In this group with 14 volunteers, they received 32% carbohydrate, 47% fat, 21% protein and 60 g of flaxseed powder / day during the period of study.

Outcomes

Primary Outcome Measures

Inflammatory markers and hormones blood levels
For detection of insulin by chemiluminescence, we used the IMMULITE 1000® SYSTEMS - SIEMENS MEDICAL SOLUTIONS DIAGNOSTICS (SIEMENS) (Los Angeles, USA). The determination of ultra-sensitive CRP (C-reactive protein) by immunoturbidimetric assay was performed with the COBAS® MIRAPLUS - ROCHE (USA). The Tumor Necrosis Factor (TNF-α), leptin, and adiponectin were measured by enzyme immunoassay method, using kits of LINCOPLEX-LUMINEX®, manufactured by Millipore Corporation (USA). Determination of 8-Iso-Prostaglandin F2a (serum isoprostane) was performed by enzyme immunoassay with ASSAYS® DESIGNS kit, Inco, USA.

Secondary Outcome Measures

Blood lipid profile
The determination of total cholesterol, high density lipoprotein (HDL-c), triglyceride, glucose and uric acid was performed by enzymatic method, with HITACHI® 912 - ROCHE (Japan). The reagent used for measurement of total cholesterol and triglyceride was CHOD-PAP, ROCHE (Japan); for HDL-c: Bioclin K071 (Japan); for glucose: GOD-PAD (Roche) (Japan); and for uric acid was Uric Acid Plus (URICASE) (Japan). To determine the values of low density lipoprotein (LDL-c) the Friedewald Formula was used.

Intervention Name(s)
Flaxseed or rice raw powder ingestion
Intervention Description
The experimental groups received isocaloric diets and different proportions of carbohydrates, and the introduction of 60g of brown flaxseed or rice raw powder. Flaxseed and raw rice were crushed weekly by minimal particle type mill and appropriate sieves for fine grinding grain with a degree to 250 mm/micrometers. After crushing flaxseed and raw rice, they were weighed in semi-analytical balance. The addition of flaxseed or raw rice powder was made in the collation (40 g added to milk) and lunch (20 g added to baked beans). The volunteers received flaxseed or rice raw powder, portioned to be used for 42 days, including the weekends.
