Omega-3 fatty acids. What consumers need to know

The general public is increasingly aware of the health benefits associated with consumption of omega-3 fatty acids. While evidence of health benefits continues to mount, the underlying science is complex. Omega-3 fatty acids vary in their physiological efficacy. Consumers are typically unaware of differences in the efficacy of different omega-3 fatty acids and this lack of knowledge can result in consumers being misled within the marketplace. There is a need for consumers to be educated about the distinctions between omega-3 fatty acids. In the interim consumers remain at risk of purchasing premium fortified products and supplements that will not correspond to their desired health outcomes. This paper summarises the current understanding of fatty acid physiological metabolism and interaction for the purpose of highlighting this complex and multifaceted concern.

Seafood: nutritional gold for seniors.

Objectives To conduct a systematic review of published evidence around seafood, health and seniors. Method Data sources reviewing included: Proquest; PubMed; Science Direct; Taylor and Francis; Cochran Collaboration; Web of Knowledge and Web of Science. Key search terms included seniors, ageing, fish, seafood, protein, health and various lifestyle conditions Results A diet high in marine source Omega-3 poly unsaturated fatty acids affords particular benefits for seniors in a reduced risk of all cause mortality, with the strongest evidence around coronary heart disease and ischemic stroke. Other benefits include reduced inflammation associated with arthritis and delay to onset and slowed progression of dementia and Alzheimer’s disease. Conclusion There is increasing evidence to support the regular seafood consumption (particularly oily fish) as being protective against a number of aged-related health conditions. Seniors should be encouraged to consume 3500mg- 4000mg of marine source Omega-3 PUFAs each week.
