What should you be doing in your 20s, 30s and 40s if you want a healthy brain at 80?
This week, we’re joined by registered dietitian and cognitive health expert Barbie Boules to talk about what we actually know about protecting our brains as we age and why brain health deserves our attention long before we start worrying about dementia.
Barbie has been a registered dietitian for over 25 years, and her work has become increasingly focused on women’s health, healthy aging and cognitive health. After her mom was diagnosed with Alzheimer’s disease, the conversation around dementia prevention and protecting cognitive function also became deeply personal for her.
We talk about the connection between cardiovascular health and brain health, including cholesterol, ApoB, Lp(a), blood pressure, insulin resistance and body composition, and why many of the things we do to protect our hearts may also matter for our brains.
We also get into brain fog and normal forgetfulness, social media and our shrinking attention spans, multitasking, AI and whether outsourcing our thinking could have consequences for cognitive health.
Then, of course, we talk nutrition: the MIND diet, berries, leafy greens, whole grains, fatty fish, coffee, alcohol, creatine and supplements. Plus, Barbie breaks down what we actually know about menopause and cognition, including the viral claim that your brain starts to “eat itself” when estrogen declines.
In this episode, we cover:
• How early brain health and cognitive decline should be on our radar
• Normal forgetfulness vs. changes worth paying attention to
• Modifiable risk factors for dementia and cognitive decline
• The connection between cholesterol, metabolic health and brain health
• Whether social media, multitasking and AI are changing how we use our brains
• The MIND diet and what to eat for long-term brain health
• Coffee, alcohol, creatine and supplements for cognitive health
• Menopause, estrogen and the female brain
• Cognitive reserve and why protecting your brain involves more than doing Sudoku
• The realistic habits you can start now to support a healthier brain later
If you’ve ever wondered how to keep your brain healthy as you age, whether brain fog is something to worry about, or what actually matters for reducing your risk of cognitive decline, this episode is for you.
