EP 74: How to Protect Your Brain as You Age: 3 Practical Brain Health Habits
“Your brain is supplied by arteries, and we want to protect our blood vessels because they are our brain’s lifeline.”
— Dr. Daniel Kessler
Brain health is becoming one of the biggest concerns for people as they age. In conversations with the community on Amelia Island, more than 90% of people surveyed said their number one concern is brain health.
That concern isn’t limited to one town or region. It’s something people everywhere are thinking about more and more as they notice changes in memory, focus, and cognitive performance.
So the real question becomes:
What can people actually do to take care of their brain as they age?
In this episode of the Nassau Health Foods Organic Living Podcast, Dr. Kessler shares practical guidance rooted in his experience working with patients and studying brain health. The message is simple: start with the basics that support the brain every day.
Why Brain Health Is Connected to Vascular Health
One of the most important ideas discussed in the conversation is something many people don’t immediately associate with the brain:
Vascular health.
The brain depends heavily on blood supply. In fact, the brain uses about 20% of the body’s blood supply.
That means the condition of your blood vessels directly impacts how well your brain functions.
When blood vessels become inflamed or stiff, or when someone has uncontrolled high blood pressure, the brain can be one of the first organs affected.
This is why protecting the health of your arteries is considered essential for maintaining cognitive function.
Dr. Kessler describes blood vessels as the brain’s lifeline, emphasizing that brain health is closely tied to how well those vessels are functioning.
Understanding Pathways That Can Affect Brain Health
The discussion also references research from Dr. Dale Bredesen, who has studied cognitive decline and Alzheimer’s disease extensively.
One of the key ideas shared is that cognitive decline can develop through multiple pathways. Among those mentioned in the conversation are:
- Inflammation
- Blood sugar regulation issues
- Environmental toxins
For example, some patients with Alzheimer’s disease have been described as having what is sometimes called type 3 diabetes, referring to the relationship between blood sugar regulation and the brain.
Environmental toxins can also play a role. As the environment becomes more toxic, substances entering the body can potentially impact the brain through the bloodstream.
Because of this complexity, brain health often requires looking at multiple factors rather than assuming a single cause.
Three Practical Brain Health Tips
While the science of cognitive health can be complex, the podcast conversation focuses on three foundational habits that anyone can begin working on.
These habits support the systems that keep the brain functioning properly.
Tip #1: Know Your Blood Pressure
The first recommendation is simple but important:
Know your numbers.
High blood pressure can develop silently, meaning people may have elevated levels without realizing it.
Tracking blood pressure regularly can help people identify whether their levels are within a healthy range.
A simple home blood pressure monitor can be used to measure readings over several days or weeks and calculate an average.
Typical readings discussed in the conversation are around:
- 120 for the top number
- 70–80 for the bottom number
Another factor tied to blood pressure is stress.
When people experience stress or anger, their blood pressure may rise. That’s why simple actions like taking a moment to breathe and calm down can make a difference.
The key point is that blood pressure is often overlooked until it becomes a problem.
But for brain health, it’s something worth monitoring early.
Tip #2: Feed Your Brain With Intention
The second tip focuses on nutrition.
Many people have heard the phrase “food is medicine.”
But the conversation expands on this idea by emphasizing that we should also feed the brain intentionally.
Nutrition affects how the brain functions because the brain has very high metabolic demands.
One practical suggestion discussed is to eat a variety of colorful foods.
The example given is the colors of a rainbow:
- Red
- Orange
- Yellow
- Green
- Blue
- Indigo
- Violet
Eating a wide range of colors can help provide nutrient-dense foods that support the body.
But brain health is not just about what we eat.
It’s also about how we eat.
Dr. Kessler encourages people to slow down and eat with intention, such as:
- Sitting down with friends or family
- Having conversations during meals
- Putting away phones
These simple habits can help people reconnect with food and community.
Engaging with others also stimulates the brain, which supports cognitive activity.
Even simple interactions—like starting a conversation with someone—can help keep the brain engaged.
Tip #3: Prioritize Sleep
The third foundational habit is sleep.
Sleep plays a critical role in maintaining brain health.
During sleep, the brain:
- Restores itself
- Detoxifies
- Maintains neural connections
One important chemical mentioned in the discussion is brain-derived neurotrophic factor (BDNF).
BDNF is associated with the brain’s ability to maintain and grow connections between neurons.
When sleep is disrupted, the brain’s ability to maintain these connections may be affected.
Sleep is also connected to several other health factors, including:
- Blood pressure
- Stress levels
- Blood sugar regulation
Because of this, sleep is not considered optional.
Instead, it’s described as a biological necessity.
Practical sleep recommendations discussed include:
- Going to bed before midnight
- Maintaining a consistent sleep schedule
- Keeping the bedroom cool
- Reducing screen time before sleep
The goal is to allow the brain the time it needs to complete its natural restoration cycle.
The Brain’s Ability to Adapt: Neuroplasticity
One of the most hopeful ideas discussed in the episode is neuroplasticity.
Neuroplasticity refers to the brain’s ability to:
- Build new pathways
- Strengthen connections
- Adapt over time
This means the brain is not simply a fixed organ that declines as people age.
Instead, it can continue to change and respond to lifestyle factors.
Learning new things, moving the body, improving sleep, and maintaining healthy habits all send signals to the brain that support these adaptive processes.
The conversation emphasizes that this ability exists at many ages.
People in their 40s, 60s, or even 80s can still benefit from supporting the brain’s ability to adapt.
A Patient Story: Addressing Root Causes
To illustrate how multiple factors can influence cognitive health, Dr. Kessler shares a story about a patient.
The patient was an executive in his early 60s who began experiencing significant cognitive challenges.
These included:
- Difficulty performing executive tasks
- Forgetting names
- Struggling with numbers
- Losing the ability to run his company effectively
The approach taken with the patient involved looking at several potential contributing factors.
First, the basics were evaluated:
- Blood pressure
- Nutrition
- Blood sugar
- Sleep
Sleep apnea was discovered and addressed.
Blood sugar issues were also identified.
Another discovery was that the patient had worked in a building with mold exposure.
Testing revealed elevated levels of certain mold-related toxins.
Once these issues were addressed through medical and nutritional support, the patient experienced major improvements.
After approximately six months, the patient reportedly regained full executive function.
He was also able to discontinue medications that had previously been prescribed for mood-related issues.
The story highlights how multiple factors can contribute to cognitive symptoms.
Addressing those factors may lead to improvements.
Why Early Awareness Matters
One of the central messages of the episode is that early signs of cognitive change should not be dismissed.
It can be tempting to assume that memory changes are simply part of aging.
But ignoring these changes may prevent people from identifying underlying factors that could be addressed.
Instead, the conversation encourages people to:
- Talk to someone knowledgeable
- Look into potential contributing factors
- Focus on foundational health habits
Starting with the basics—blood pressure, nutrition, and sleep—can be a powerful first step.
From there, additional factors can be explored if needed.
Taking Control of Your Brain Health
A final message from the conversation is about empowerment.
People have more control over their daily habits than they might realize.
Examples include:
- Choosing what to eat
- Deciding when to go to sleep
- Selecting the people they spend time with
These everyday choices can play a meaningful role in supporting brain health.
The encouraging takeaway is that many aspects of brain health are influenced by actions people can take today.
