Fish oils reduce hunger in overweight and obese volunteers on a weight loss diet - From the Department of Physiology and Nutrition at University of Navarra in Pamplona, Spain comes the news that long chain omega-3 fatty acids (fish oils) are considered nutritional factors with a potential to modulate food intake. Thus, the aim of the current study was to determine whether appetite could be affected by long chain fatty acids when included in a calorie-restricted diet to treat overweight or obesity.
A new study involving hypertriglyceridemic men has found that the fish oil docosahexaenoic acid (DHA) may decrease a specific blood cholesterol (called remnant-like particle-cholesterol (RLP-C) and increase the RBC omega-3 index, thereby improving cardiovascular health.
Plasma remnant-like particle-cholesterol (RLP-C) and the RBC (n-3) index are novel risk factors for cardiovascular disease.
Hypertriglyceridemic men aged 39–66 years, participated in a randomized, placebo-controlled, parallel study.
They received no supplements for 8 days and then received either 7.5 g/d DHA oil (3 g DHA/d) or olive oil (placebo) for the last 90 days.
Fasting blood samples were collected on study days: 0 (baseline), 45 (mid-intervention), 84, and 91 (end-intervention).
Continued supplementation with DHA between d 45 and 91 further increased the RBC (n-3) index (162%) and plasma EPA:AA (137%) compared with baseline values.
