Best Practices for Maintaining Brain Health

We often think of brain health as something to consider only when signs of cognitive decline begin. But the truth is, the most effective time to protect and nourish your brain is long before symptoms arise—especially during midlife. This stage of life brings a unique window of opportunity to lay the foundation for sharp thinking, emotional balance, and lasting vitality as we age.

Your brain is the command center of your entire being—impacting memory, focus, mood, decision-making, and even relationships. Yet, many of us are unaware of the silent processes already underway that can either support or sabotage brain health over time.

More than 6 million Americans are currently living with Alzheimer’s disease—a number projected to double by 2050 if preventive strategies are not implemented. Genetics, particularly carrying the APOE4 allele, can significantly increase an individual’s risk of developing late-onset Alzheimer’s. However, genetic risk is not destiny.

In fact, research from the fields of epigenetics and lifestyle medicine reveals that up to 40% of dementia cases may be preventable through modifiable lifestyle factors such as nutrition, movement, sleep, and toxin exposure.

So why wait until symptoms appear?

The Foundations of Brain Health

Mindset and Mental Resilience

When it comes to preserving brain health, your mindset matters more than you might think. Scientific studies show that a positive, growth-oriented mindset not only enhances emotional well-being but can also reduce the risk of cognitive decline. This is especially important during midlife, when stress, life transitions, and high-demand careers can wear down mental reserves.

One of the brain’s most remarkable qualities is its neuroplasticity—its ability to rewire and regenerate in response to experiences and habits. This means your brain is constantly reshaping itself based on how you think, what you believe, and how you respond to challenges.

At Caring for the Body, PLLC, we guide our patients in developing daily mental wellness rituals that strengthen brain pathways and reduce stress-related damage. These simple yet powerful tools include:

  • Journaling to process emotions and clarify intentions
  • Gratitude practices to shift perspective and boost resilience
  • Positive affirmations to challenge limiting beliefs and foster hope

Nutrition for Cognitive Function

Food is not just fuel—it’s information for your brain. Every bite you take influences inflammation, blood sugar balance, and neurotransmitter production.

A nutrient-dense, anti-inflammatory diet is one of the most powerful strategies to protect against cognitive decline. Key brain-supportive foods include:

  • Omega-3-rich fats from wild salmon, walnuts, and flaxseeds
  • Dark leafy greens like kale and spinach, high in folate and antioxidants
  • Berries, rich in flavonoids that support memory and neuroplasticity
  • Avocados, olive oil, and coconut for healthy fats that support cell membranes

Equally important is what you avoid. Highly processed foods, artificial sweeteners, excessive sugar, and trans fats contribute to systemic inflammation and insulin resistance—two major contributors to cognitive decline.

For those who carry the APOE4 gene variant, dietary choices are even more critical. APOE4-positive individuals may be more sensitive to saturated fats and blood sugar swings. In these cases, we help tailor a precision nutrition plan that supports detox pathways, mitochondrial function, and brain longevity—without relying on guesswork.

Movement and Exercise

Physical movement is one of the most underutilized (yet highly effective) brain optimization tools.

Regular aerobic and resistance training have been shown to promote neurogenesis, the growth of new brain cells, particularly in the hippocampus—the area responsible for memory and learning. In fact, exercise increases BDNF (brain-derived neurotrophic factor), a key protein that supports neural plasticity and repair.

We encourage our patients—especially in midlife—to reframe movement not as punishment, but as medicine. Beneficial activities include:

  • HIIT (High Intensity Interval Training) to boost blood flow and oxygenation
  • Yoga and stretching to regulate the nervous system and improve mobility
  • Walking in nature to reduce cortisol and support cardiovascular health

Detoxification and Environmental Protection

Avoiding Brain Toxins

When it comes to maintaining optimal brain health, one of the most overlooked yet critical strategies is reducing your exposure to environmental toxins. From the air we breathe to the food we eat and the products we use daily, we are constantly interacting with substances that can silently damage brain tissue, accelerate aging, and disrupt neurochemical balance.

Some of the most concerning brain toxins include:

  • Heavy metals like mercury, lead, and aluminum, which have been linked to memory loss and neurological diseases.
  • Mold toxins (mycotoxins), often found in water-damaged homes and buildings, which can cause brain fog, fatigue, and mood changes.
  • Plastics and endocrine-disrupting chemicals (such as BPA and phthalates) that interfere with hormonal regulation crucial for brain function.
  • Pesticides and herbicides, commonly present in non-organic produce, which are neurotoxic and contribute to inflammation.

Protecting your brain starts with making intentional choices in your environment. At Caring for the Body, PLLC, we help patients create a "low-toxin lifestyle" by assessing potential sources of exposure and recommending practical upgrades to improve:

  • Air quality (through HEPA filters and avoiding synthetic fragrances)
  • Water purity (using high-quality filtration systems)
  • Food sourcing (prioritizing organic, whole-food nutrition and reducing packaged products)

Detox Strategies

True detoxification isn’t about a trendy juice cleanse—it’s about supporting your body’s innate ability to process and eliminate toxins safely and effectively. In our clinic, we focus on gentle, sustainable protocols that align with your unique biology and health status.

Some of the most effective brain-friendly detox tools include:

  • Infrared sauna therapy, which promotes sweating and improves circulation to aid toxin elimination.
  • Binders like activated charcoal, chlorella, or specific supplement formulations (e.g., GI Detox, IgG Shield), which help capture and remove toxins through the GI tract.
  • Liver support nutrients (such as glutathione precursors, milk thistle, and sulforaphane) to enhance phase I and II detox pathways.
  • Gut repair protocols, since a healthy microbiome is essential for filtering neurotoxins and maintaining the blood-brain barrier.

But detox isn’t just physical—it’s also emotional and mental.

Modern life is full of chronic stressors and mental clutter that act as invisible toxins to your brain. Constant exposure to negative news, social media comparison, and high-pressure environments keeps your nervous system in a state of chronic fight-or-flight.

We guide our patients to implement a personalized emotional detox, which may include:

  • Setting digital boundaries and limiting exposure to distressing media
  • Releasing toxic relationships and redefining personal space
  • Creating quiet time for reflection, prayer, or meditation

Sleep, Stress & Spiritual Renewal

Sleep Hygiene

Your brain’s most powerful repair mechanism activates while you sleep. During deep, restorative sleep, the glymphatic system—a specialized waste clearance system in the brain—flushes out toxins, including beta-amyloid, a protein linked to Alzheimer’s disease. Without adequate sleep, this cleansing process is impaired, leading to inflammation, memory issues, and accelerated cognitive aging.

At Caring for the Body, PLLC, we emphasize sleep as non-negotiable medicine for the brain. Optimizing sleep hygiene can significantly improve mood, focus, and long-term brain resilience.

Tools we recommend:

  • The Oura Ring to track sleep cycles, readiness, and recovery metrics.
  • A Sleep Hygiene Checklist, including:
    • Consistent sleep/wake times (even on weekends)
    • No screens 1–2 hours before bed
    • Cooling the bedroom to 65–68°F
    • Limiting caffeine and alcohol
    • Gentle evening routines (e.g., stretching, herbal teas, magnesium)

Stress Resilience

Modern life demands a lot of our mental bandwidth. Chronic stress triggers persistent surges of cortisol, a hormone that—when unregulated—can shrink the hippocampus, impair memory, and reduce executive function. Over time, this wears down brain health and contributes to mood disorders, burnout, and even dementia risk.

Building stress resilience is not about eliminating stress entirely—it’s about learning to recover from it quickly and gracefully.

We guide our patients in cultivating daily rhythms of rest and renewal, including:

  • Prayer and meditation to center the mind and nourish the spirit
  • Breathwork to regulate the nervous system and improve heart rate variability
  • Nature therapy—a walk in the woods or sunlight on your face can calm the brain and elevate mood
  • Mindset practices to reframe stress as a challenge, not a threat

Spiritual Connection

In our practice, we believe that caring for the soul is essential for nourishing the mind. Spiritual well-being is deeply intertwined with emotional resilience and cognitive health.

A sense of meaning, purpose, and belonging can be protective against cognitive decline and depression. Research even shows that faith-based practices are associated with lower cortisol levels, improved immune function, and enhanced neural connectivity in areas related to empathy, reflection, and hope.

Dr. Libert integrates faith-inspired guidance into care for those who desire it, creating space for:

  • Reflective prayer and scripture as tools for inner peace
  • Connection with a faith community for emotional support
  • Exploring spiritual gifts and purpose, especially in the second half of life
