In the UK, one in 14 people over 65 will develop dementia, with that figure rising to one in six once we’re over 80. It’s fair to say it’s the disease many people fear the most. But this podcast makes it clear that cognitive decline is not a natural or inevitable part of ageing.

Dr. Tommy Wood has a biochemistry degree from the University of Cambridge, a medical degree from the University of Oxford and a PhD in physiology and neuroscience from the University of Oslo.

Mindsip insights from this episode:

Beware of medications that deplete vitamin B12 absorption

Widely prescribed medications such as Metformin and proton pump inhibitors for acid reflux can impair the body's ability to absorb vitamin B12.

Understand fat's role in human baby brain development

Unlike other mammals, human babies are born with fat, which serves as a critical storage depot for the omega-3 fatty acid DHA to fuel their rapidly growing brains.

Prioritize seafood for cognitive benefits despite mercury risks

Studies suggest that even with a high mercury burden from eating a lot of seafood, the cognitive benefits from the omega-3s appear to outweigh the risks.

Challenge normalization of weakness; strengthen grip strength standards

Instead of addressing why population-level grip strength is declining, some have proposed simply lowering the 'normal' range, effectively normalizing weakness.

Question standard blood ranges for optimal health

Standard 'normal' ranges for blood tests are often based on an average population that is already sick, meaning 'normal' isn't necessarily optimal for health.

Ensure adequate omega-3s to maximize B vitamin benefits for brain health

The brain-protective benefits of B vitamin supplementation are most significant in individuals who also have adequate levels of long-chain omega-3s like EPA and DHA.

Aim for optimal B12 levels to enhance cognitive function

For optimal cognitive function, some experts recommend treating serum B12 levels that are below 600, even if they fall within the standard 'normal' lab range.

Challenge unethical treatment of aging humans in society

Socially isolating humans or removing cognitive stimulus is a common practice for the elderly, yet it's considered unethical to do to lab animals without a very good reason.
