The epidemic character of depressive disorders has prompted further research into dietary habits that could make an etiological contribution. One clear change in the diet of the population in developed countries has been the replacement of omega-3 polyunsaturated fatty acids by saturated fats and trans-fats as well as by omega-6 polyunsaturated fatty acids. Omega-3 and omega-6 fatty acids are e...

Summary) When these problems start to have an adverse impact on school performance and behaviour, the child may be diagnosed with attention deficit hyperactivity disorder (ADHD). Research has established that omega3 fatty acids are crucial for healthy infant brain development, and researchers are also finding that omega-3 deficiencies might be related to a range of mental health problems includ...

Transgenic mice (named "Omega mice") were engineered to carry both optimized fat-1 and fat-2 genes from the roundworm Caenorhabditis elegans and are capable of producing essential omega-6 and omega-3 fatty acids from saturated fats or carbohydrates. When maintained on a high-saturated fat diet lacking essential fatty acids or a high-carbohydrate, no-fat diet, the Omega mice exhibit high tissue ...

High insulin levels in obese people are considered as a risk factor to induce breast carcinogenesis. And consumption of fish oils which mainly contain omega-3 fatty acids is associated with a reduced risk of breast cancer. However, whether omega-3 free fatty acids (FFAs) modulate insulin signaling pathway to prevent breast cancer is poorly understood. The current study tested the hypothesis tha...

Greater amounts of physical activity (PA) and omega-3 fatty acids have both been independently associated with better cognitive performance. Because of the overlapping biological effects of omega-3 fatty acids and PA, fatty acid intake may modify the effects of PA on neurocognitive function. The present study tested this hypothesis by examining whether the ratio of serum omega-6 to omega-3 fatt...

What are Omega-3 Fatty Acids and Why are They Helpful? Omega-3 fatty acids have become quite popular because of the many positive effects on human health. Omega-3 fatty acids benefit both healthy people as well as those with cardiovascular disease. Omega-3 fatty acids are thought to improve heart health by lowering triglycerides, raising good cholesterol (HDL, or high density lipoprotein), thin...

As for saturated and monounsaturated fatty acids, the omega-6 and omega-3 polyunsaturated fatty acids (PUFA) are chemically linked to fat structures known as triglycerides in the various foods and oils that are consumed. The natural triglyceride or fat structure consists of a 3-carbon glycerol backbone onto which 3 long-chain fatty acids of varying types and structures are linked or 'esterified...

BACKGROUND Physical exercise and healthy dietary habits are recommended to prevent breast cancer. DISCUSSION Increased intake of omega-3 fatty acids associated with decreased omega-6 - resulting in higher omega-3 to omega-6 ratio compared with Western-type diet - is inversely associated with breast cancer risk. The modernized Mediterranean diet with high omega-3 to omega-6 ratio, high fiber a...

We have remodeled canola seeds to accumulate the omega-3 fatty acid, stearidonic acid (SDA). In doing so, we have demonstrated the feasibility of developing a land-based source of functional omega-3 fatty acids on a large scale. Land-based omega-3 fatty acids represent a sustainable source of omega-3 fatty acids that can be produced on large acreages and delivered to consumers in a wide variety...
