Effect of Dietary Supplemental Fish Oil in Alleviating Health Hazards Associated With Air Pollution

Participants of this randomized double-blind placebo-controlled trial include 70 healthy Chinese adults. The investigators randomly assign participants to two parallel groups at baseline using a random-number table. Compliance is determined by directly observed supplement intake. Participants in fish oil group are assigned to receive 2.5 g/day in divided doses. Each capsule contains 60% n-3 PUFA \[24% docosahexanoic acid (C22:6 n-3 DHA) and 36% eicosapentaenoic acid (C20:5 n-3 EPA)\].

Participants of this randomized double-blind placebo-controlled trial include 70 healthy Chinese adults. The investigators randomly assign participants to two parallel groups at baseline using a random-number table. Compliance is determined by directly observed supplement intake. Participants in sunflower seed oil group receive 2.5 g/day in divided doses, and the capsules are identical as the fish oil capsules.
