What is the primary health benefit associated with omega-3 fatty acids?

The primary health benefit associated with omega-3 fatty acids is improved cognitive function. Omega-3 fatty acids, particularly those found in fish oil—like EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—are essential for brain health and development. They play a crucial role in maintaining the structure and function of brain cells. Research has shown that adequate intake of omega-3s is linked to better cognitive performance, including improvements in memory and mood, and may also help reduce the risk of cognitive decline and dementia as individuals age.

This benefit is supported by numerous studies suggesting that omega-3 fatty acids can enhance neuroplasticity, promote the production of neuroprotective factors, and reduce inflammation in the brain. These effects combine to support overall cognitive health.

The other options highlight aspects that do not represent primary benefits of omega-3 fatty acids. For instance, increased risk of heart disease contradicts the well-documented cardiovascular benefits of omega-3s, while weight gain and reduced skin sensitivity are not direct health benefits associated with these fatty acids and do not reflect the substantial amount of evidence favoring omega-3s for cognitive enhancement and overall health.
