Optimizing Brain Health with DHA, B Vitamins and Lifestyle
In recent years the spotlight has shifted to the critical roles played by B vitamins and DHA (omega-3) in brain health and preventing cognitive decline. Studies collectively indicate a connection between the levels of B vitamins and omega-3 and their influence on cognitive decline and brain atrophy. To put it simply, it’s likely that both are necessary for DHA to be effectively integrated into neuronal membranes for optimal functionality.
In the 2020 Lancet Commission report, an extensive examination of dementia was conducted with an aim to determine the preventable proportion of this condition. Their estimation concluded that 40% of dementia cases could be prevented, considering various risk factors like physical activity, body composition, diet quality, smoking, hearing loss (which can be seen as a reduction in cognitive demand), and educational status.
It’s worth noting that this estimate might be conservative, as certain factors like sleep and nutrient status, especially homocysteine levels, were not factored in. Some experts suggest that these factors alone could contribute to a population attributable risk of approximately 20%.
In this article we delve into the mechanisms by which B vitamins, in tandem with omega-3, impact heart and brain health, as well as strategies for harnessing their benefits.
