NCT01857167

Brief Summary

This study is to examine the change of fasting insulin, glucose, insulin sensitivity and related traits in response to the six month treatment of omega-3 fatty acids, including fish oil and flaxseed oil, in Chinese type 2 diabetic patients. Corn oil, rich in omega-6 fatty acids, will be selected as a controlled oil. The investigators hypothesize that omega-3 fatty acids could improve insulin sensitivity and glucose metabolism in Chinese type 2 diabetic patients.

Outcome Measures

Primary Outcomes (1)

  • insulin resistance

    180 days

Study Arms (3)

Fish Oil Supplementation

EXPERIMENTAL

Patients will receive fish oil capsules, at a dose of 4g/day. Each 1g capsule will contain 300mg of EPA and 200mg of DHA.

Dietary Supplement: Fish Oil Supplementation

Flaxseed Oil Supplementation

EXPERIMENTAL

Patients will receive flaxseed oil capsule, at a dose of 4g/day. Each 1g capsule will contain 630mg of ALA

Dietary Supplement: Flaxseed Oil Supplementation

Placebo Supplementation

PLACEBO COMPARATOR

Patients will receive corn oil in the capsules at the same dose as fish oil. The corn oil will appear identical in size and color to the fish oil.

Dietary Supplement: placebo
