Subgroup analyses showed that using whole flaxseed in doses ≥30 g d-1 , longer-term interventions ( ≥12 weeks ) and studies including participants with higher BMI ( ≥ 27 kg m-2 ) had positive effects on body composition  .
Whole flaxseed is a good choice for weight management particularly for weight reduction in overweight and obese participants
Flaxseed consumption may be inversely associated with obesity ; however , findings of available r and omized controlled trials ( RCTs ) are conflicting .
The present study aim ed to systematic ally review and analyse RCTs assessing the effects of flaxseed consumption on body weight and body composition .
Omega-3 fatty acids and lipoprotein associated phospholipase A2 in healthy older adult males and females
Purpose Lipoprotein associated phospholipase A2 ( Lp-PLA2 ) is a novel inflammatory factor that has been independently associated with stroke and cardiovascular disease ( CVD ) . Omega-3 fats have been implicated in reducing inflammation associated with CVD . The aim of this study was to determine if an 8-week isocaloric diet supplemented with eicosapentaenoic acid ( EPA ) and docosahexaenoic ( DHA ) in the form of fish oil or α-linolenic acid ( ALA ) in the form of flaxseed oil would alter Lp-PLA2 among healthy adults ages 50 years and older . Methods Fifty-nine healthy adults ( ~75 % female , average age 61 years ) were r and omized to one of three groups with equal amounts of total fat intake . All capsules contained ~1 g of fat . The control group ( n = 19 ) consumed olive oil capsules ( ~11 g/day ) ; the ALA group ( n = 20 ) consumed flaxseed oil capsules ( ~11 g/day ) and the EPA/DHA group ( n = 20 ) consumed fish oil capsules ( ~2 g/day + 9 g/day of olive oil ) . Fasting blood sample s were obtained before and after the 8-week intervention for determination of Lp-PLA2 mass and activity as well as lipid values . Results We did not find any significant changes in Lp-PLA2 mass or activity after the intervention in any of the groups ; however , change in oxidized LDL was associated with change in Lp-PLA2 mass ( r = 0.37 , p < 0.01 ) . ConclusionS upplementing the diet with omega-3 fatty acids for 8-weeks did not influence Lp-PLA2 activity or mass among older adults ; altering oxidized LDL may be necessary to see changes in Lp-PLA2 levels
