Outcome Measures

Primary Outcomes (1)

  • 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.

    After 12-hour fast, in the first and 42th day of intervention

Secondary Outcomes (1)

  • Blood lipid profile

    After 12-hour fast, in the first and 42th day of intervention

Study Arms (4)

Control group

NO INTERVENTION

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

Flaxseed group

EXPERIMENTAL

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.

Other: Flaxseed or rice raw powder ingestion

Rice and low carb group

EXPERIMENTAL

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.

Other: Flaxseed or rice raw powder ingestion

Flaxssed and low carb group

EXPERIMENTAL

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.

Other: Flaxseed or rice raw powder ingestion

Interventions

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.
