● Polyunsaturated Faty Acids are essential fatty acids.

Answer 2

Answer:

Linoleic acid (LA), an omega-6 fatty acid, and α-linolenic acid (ALA), an omega-3 fatty acid, are considered essential fatty acids because they cannot be synthesized by humans. (More information)

The long-chain omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), can be synthesized from ALA, but due to low conversion efficiency, it is recommended to consume foods rich in EPA and DHA. (More information)

Both omega-6 and omega-3 fatty acids are important structural components of cell membranes, serve as precursors to bioactive lipid mediators, and provide a source of energy. Long-chain omega-3 polyunsaturated fatty acids (PUFA in particular exert anti-inflammatory effects; it is recommended to increase their presence in the diet. (More information)

Both dietary intake and endogenous metabolism influence whole body status of essential fatty acids. Genetic polymorphisms in fatty acid synthesizing enzymes can have a significant impact on fatty acid concentrations in the body. (More information)

DHA supplementation during pregnancy may reduce the risks of early premature birth (birth before 34 weeks' gestation) and very low birth weight (<1.5 kg [<3 pounds 5 ounces]). (More information)

DHA is important for visual and neurological development. However, supplementation with long-chain during pregnancy or early infancy appears to have no significant effect on children's visual acuity, neurodevelopment, and physical growth. (More information)

Replacing saturated fat in the diet with omega-6 lowers total blood cholesterol; yet, randomized controlled trials have failed to demonstrate cardiovascular benefits in healthy people and people at risk for or with type 2 diabetes mellitus. Long-chain omega-3 PUFA supplementation may be useful to reduce mortality in patients with prevalent coronary heart disease (CHD) and in those with heart failure without preserved ventricular function. (More information)

Increasing EPA and DHA intake may benefit individuals with type 2 diabetes mellitus, especially those with elevated serum triglycerides. However, evidence from large-scale randomized trials is insufficient to support the use of omega-3 PUFA supplements for cardiovascular disease prevention in those with type 2 diabetes.

Observational studies have found fish intake to be associated with lower risks of cognitive deterioration and Alzheimer’s disease, but it is not yet clear whether supplementation with marine-derived omega-3 PUFA can help prevent cognitive decline. (More information)

Several omega-3 formulations have been approved by the US Food and Drug Administration for the indication of treating severe hypertriglyceridemia. (More information)

Although omega-3 PUFA deficiency may not be uncommon in neurodevelopmental and neuropsychiatric disorders, there is little evidence to suggest that supplementation may be a beneficial adjunct in the management of affected individuals. (More information)

The Food and Nutrition Board of the US Institute of Medicine (now the National Academy of Medicine) established adequate intakes (AI) for omega-6 and omega-3 fatty acids. (More information
