Omega-3 Metabolic Syndrome

B エビデンス 少なくとも1件のランダム化試験がこれを支持しており、おおむね一貫した結果が得られています。

Systematic review of 44 RCTs found omega-3 significantly reduces triglycerides by 15-30% and reduces waist circumference by 0.81 cm. Fish oil combined with exercise produces greater body fat reduction than either alone. Benefits include PPAR-gamma activation and anti-inflammatory effects.
