The flaxseed role as cholesterol reducing agent and weight loss
Abstract
Flaxseed (Linum usitatissimum L.) is widely used by the population as a functional food, because it is rich in linolenic acid, lignans, and dietary fibers, which are related to cholesterol control, increasing satiety and consequently weight loss, and reducing the incidence of various diseases, including cardiovascular disease. The aim of this study was to evaluate the effects of daily intake of ground golden flaxseed on lipid and anthropometric profile; and to apply a questionnaire to assess the implications of this on the health of volunteers. For this purpose, 20 volunteers were instructed to ingest 20g of ground golden flaxseed, daily, for 60 days. Total cholesterol, LDL, HDL, triglycerides and BMI were determined before and after the flaxseed supplementation. For the biochemical parameters, no significant differences were observed in the established period. Nevertheless, it was found significant BMI reduction in 10% of the volunteers after 60 days of seeds ingestion. Supplementation with flaxseed was well accepted by the participants, who reported the benefits, such as intestinal regulation (75%), energy source (25%), weight loss (15%) and reduction of PMS or menopause symptoms (54%). Possibly the flaxseeds administration for a longer time, combined with physical activity and a diet rich in polyunsaturated fatty acids might reduce triglycerides and cholesterol.
