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 .
Effect of flaxseed on blood lipid level in hyperlipidemic patients.
INTRODUCTION Hyperlipidemia is one of the most important risk factors of ischemic heart disease . Previous studies showed that flaxseed has the potential to improve lipid profiles . In this study we investigated the effects of flaxseed powder intake on lipid profiles of patients with hyperlipidemia . MATERIAL S AND METHODS This study was a r and omized controlled clinical trial . Seventy patients with hyperlipidemia participated in the research . After detailed diet and lifestyle education , blood sample s were collected from the participants . Patients with hyperlipidemia were r and omly divided in to two intervention and control groups . The intervention group received 30 g of raw flaxseed powder every day for 40 days . Serum lipids were measured again in two groups after that time . Activity and food intakes of two groups were recorded . RESULTS In the intervention group , weight and body mass index were considerably reduced . Total cholesterol was reduced in the intervention group and increased in the control group , both of which were significant . Low density lipoprotein significantly increased in the control group and reduced in intervention group ; also , triglyceride was increased in the control group and reduced in the intervention group , which were significant Table 1 . CONCLUSION Based on the findings obtained in this research , flaxseed powder intake desirably reduced serum lipids . The differences between two groups on the basis of analysis of covariance test were significant . In all cases except for the HDL-c , this is an effective intervention . Therefore , flaxseed may be regarded as a useful therapeutic food for reducing hyperlipidemia
