Health Impact of Fish Oil
A new research on correlation between the health of obese patients and diet which includes taking fish oil has been recently conducted in the University of Western Australia. The released study suggests that weigh-loss diet which includes regular fish oil intake can reduce blood pressure, lower triglyceride levels and increase HDL2 (good) cholesterol levels. It does all this while also improving glucose tolerance.
The research included observation of 63 overweight men and women who has been undergoing hypertension treatment. The patients were randomly assigned to four groups. The first group was prescribed to include fish meal which consisted of turbot, tuna, sardines or salmon fish into their diet daily. The second group had usual calorie-restricted diet; the third one consumed calorie-restricted diet along with a daily fish meal; and the fourth one was a control group. Before and after 16 weeks of the experiment participants had their blood pressure, fatty acid profile, glucose tolerance and cholesterol levels measured for changes.
At the end of the experiment it has been determined that both calorie-restricted diets achieved an average weight loss of 12 lb (5.6 kg) in the first 12 weeks. No significant weight loss was noticed in the control group and oily fish meal only group. For people in the calorie-restricted group blood pressures levels decreased by 5.5 mm Hg (systolic) and 2.2 mm Hg (diastolic), while for those in the third group who consumed the calorie-restricted diet with fish oil numbers decreased by 13.0 mm Hg and 9.3 mm Hg respectively, which results in twice the benefit. Additionally, the combination of fish oil intake with weight loss diet improved glucose and insulin metabolism considerably. It also shown 38% reduction in triglyceride levels and 24% increase in HDL2 cholesterol for people in that group.
Conclusively, the combination of weight loss diet that consists of calorie-restricted meals with daily fish oil consumption significantly reduces the risk of cardiovascular disease among obese people…
