To investigate whether supplementation with iodine-reduced kelp (Laminaria japonica<\/em>) powder decreases body fat composition in overweight Japanese subjects, a randomized, double-blind, placebo-controlled intervention study was conducted in 50 Japanese subjects with body mass index (BMI) \u226525 and <30 kg\/m2<\/sup>. Subjects were randomly assigned to consume thirty tablets\/d (10 tablets orally, 3 times\/d) containing either iodine-reduced kelp powder (test, 6 g kelp powder corresponding to 3 g alginate\/d) or kelp-free powder (placebo) for 8 weeks. <\/p>\n\n\n\n Anthropometric measurements, blood lipids, and serum thyroid hormone levels were obtained before and after the trial. <\/p>\n\n\n\n Body fat percentage was significantly decreased in male subjects from the test group compared with the placebo group. <\/p>\n\n\n\n The same tendency was observed for body weight (p<\/em>\u00a0= 0.065) and BMI (p<\/em>\u00a0= 0.072) in male subjects. No significant changes in anthropometric measurements or visceral fat area were observed in female subjects. <\/p>\n\n\n\n Serum thyroid hormone concentrations did not increase after 1.03 mg\/d of iodine supplementation through kelp intake. The intake of iodine-reduced kelp powder led to significant and safe reductions in body fat percentage in overweight male subjects. <\/p>\n\n\n\n The consumption of kelp high in alginate may contribute to preventing obesity without influencing thyroid function in Japanese subjects with a relatively high intake of iodine from seaweed.<\/strong><\/p>\n\n\n\n Keywords: <\/strong>alginate; body fat percentage; iodine; kelp; thyroid hormone.<\/p>\n\n\n\n Source : https:\/\/pubmed.ncbi.nlm.nih.gov\/34206160\/<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Seiichiro Aoe et al.
