Fish Oil Supplementation
This group receive 2.5 g/day (two 1.25-g capsules daily) of fish oil (marine-derived n-3 PUFA) for 4 consecutive months.
Fish oil supplementation: 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 \[24% docosahexanoic acid (C22:6 n-3 DHA) and 36% eicosapentaenoic acid (C20:5 n-3 EPA)\].

Sunflower Seed Oil Supplementation
This group receive 2.5 g/day (two 1.25-g capsules daily) of placebo (sunflower seed oil) for 4 consecutive months.
Sunflower seed oil supplementation: 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. Each capsule containes 14.4% palmitic acid (C16:0), 16.0% oleic acid (C18:1 n-9), and 57.6% linoleic acid (C18:2 n-6).

Timeframe: Blood samples are obtained at the end of each round of 4 follow-ups with an interval of 2 weeks in the last 2 months of intervention.Peripheral blood samples (5 ml) were drawn, separated into serum, and stored at -80 ℃ within 30 minutes. We also measure GSH-Px. The values in the following Outcome Measure Data Table refer to the means of measurements at 4 follow-ups.

Fish Oil Supplementation
n=34 Participants
This group receive 2.5 g/day (two 1.25-g capsules daily) of fish oil (marine-derived n-3 PUFA) for 4 consecutive months.
Fish oil supplementation: 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 \[24% docosahexanoic acid (C22:6 n-3 DHA) and 36% eicosapentaenoic acid (C20:5 n-3 EPA)\].

Sunflower Seed Oil Supplementation
n=31 Participants
This group receive 2.5 g/day (two 1.25-g capsules daily) of placebo (sunflower seed oil) for 4 consecutive months.
Sunflower seed oil supplementation: 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. Each capsule containes 14.4% palmitic acid (C16:0), 16.0% oleic acid (C18:1 n-9), and 57.6% linoleic acid (C18:2 n-6).

Timeframe: Blood pressure are measured at the end of each round of 4 follow-ups with an interval of 2 weeks in the last 2 months of intervention.After sitting in a quiet room for at least 5 min, participants had their left upper arm blood pressure measured by trained technicians using an electronic sphygmomanometer at least three times with 3-min minimum intervals between measurements. The second and third sets of readings were averaged to obtain systolic BP (SBP) and diastolic BP (DBP). If the differences among the three measurements were bigger than 5 mmHg, a new round of measurements was arranged. The values in the following Outcome Measure Data Table refer to the means of measurements at 4 follow-ups.
