Introduction

In this episode of "Am I Doing It Wrong?", hosts Raj Panjabi Johnson and Noah Michelson delve into the intricacies of brain health. Recognizing that the brain often goes overlooked in daily wellness routines, they bring in Dr. Rita Achary, a seasoned neurologist specializing in preventative neurology, to shed light on maintaining a healthy brain through various means including nutrition, lifestyle choices, and more.

What Defines a Healthy Brain?

Dr. Rita Achary opens the discussion by explaining that a healthy brain is not just about cognitive abilities but also about the brain's role in controlling every aspect of our bodies. She emphasizes the brain's connectivity through nerves and its dynamic nature throughout different life stages.

Dr. Rita Achary [04:13]: "The brain does a lot of work throughout our lifetimes. We start off when we're born, our brains aren't even completely formed... As we age, different things happen."

Raj and Noah express their newfound understanding of the brain’s complexity, especially in relation to aging.

Brain Development and Aging

Dr. Achary discusses the brain's development, highlighting that it continues to mature well into our late 20s and early 30s. She explains the natural slowing of cognitive processes as the brain accumulates more memories and experiences, likening the brain to a hard drive that slows down as it fills up.

Dr. Rita Achary [06:23]: "If we think about the brain as a hard drive, the more you store on it, it's going to be just a little bit slower."

The hosts reflect on societal perceptions of aging, advocating for a healthier perspective that views cognitive slowing as a natural process rather than a negative decline.

Nutrition and Brain Health

Dr. Achary underscores the critical role of nutrition in maintaining brain health. She introduces the concept of high calorie malnutrition, where individuals consume excessive calories from processed foods but lack essential micronutrients.

Importance of Micronutrients

She shares compelling anecdotes, such as a patient with scurvy, to illustrate the consequences of micronutrient deficiencies.

Dr. Rita Achary [11:54]: "We suffer in the United States from something called high calorie malnutrition. We are drowning in a sea of calories but malnourished in a sea of calories."

Issues with Modern Diets

The discussion highlights the importance of a balanced diet rich in vitamins and minerals, advocating for whole foods over processed alternatives.

Dr. Rita Achary [13:59]: "For brain health, you need a completely balanced diet. We don't make vitamins and minerals; we store a little bit of some but not enough."

Supplements: Are They Effective?

When questioned about the efficacy of brain supplements like Prevagen, Dr. Achary is skeptical, emphasizing that nootropics often lack substantial benefits beyond common stimulants like caffeine.

Dr. Rita Achary [17:21]: "They don’t help you. The Wellness Industrial Complex tries to sell us the idea that... but we are not smarter than our bodies."

She reminisces about her grandfather, a physician who relied on diet and minimal medication to treat patients, contrasting it with the over-reliance on pharmaceuticals today.

Impact of Alcohol and Cannabis on the Brain

The conversation shifts to substances like alcohol and cannabis, examining their effects on brain health.

Alcohol Consumption

Dr. Achary acknowledges the historical and cultural significance of alcohol but warns against excessive consumption, citing studies linking regular drinking to hippocampal shrinkage.

Dr. Rita Achary [24:06]: "If you do one drink a day for a year, your hippocampus starts to shrink."

She recommends moderation and periodic abstinence to allow the body to recover.

Cannabis Use

Discussing cannabis, Dr. Achary points out the lack of comprehensive studies on its long-term effects. She notes potential negative impacts on memory and increased rates of psychosis among heavy users.

Dr. Rita Achary [26:58]: "Cannabis is excellent at extracting all of the heavy metals from the soil... but regular use is really not great for the brain."

She emphasizes the need for cautious and informed use, drawing parallels with medicinal applications like Epidiolex.

Other Dietary Concerns: Salt and Sugar

Dr. Achary addresses common dietary pitfalls related to salt and sugar intake.

Salt and Iodine Deficiency

She explains the critical role of iodine in brain development and thyroid function, lamenting the shift from iodized to gourmet salts leading to widespread iodine deficiency.

Dr. Rita Achary [29:28]: "We have now all using kosher salt, diamond salt, Himalayan salt... I'm discovering iodine deficiency."

Sugar Intake

On sugar, Dr. Achary advises minimizing refined sugars, advocating for natural sweeteners like honey and maple syrup. She highlights the brain's significant investment in taste and smell and the importance of training palates to accept less sweetness.

Dr. Rita Achary [34:44]: "The less refined sugar is, the better it is for us... If you can eat a little bit less sweet, you can train your palate."

The Role of Exercise

Exercise emerges as a cornerstone of brain health. Dr. Achary recommends at least 30 minutes of continuous, mild to moderate activity daily, citing studies that link regular exercise to significantly reduced risks of memory disorders.

Dr. Rita Achary [36:31]: "30 minutes of sustained activity reduces your risk of developing memory disorder by 30%... one hour reduces it by 70%."

The hosts resonate with the simplicity and profound benefits of activities like walking, underscoring that intense gym sessions aren't necessary for cognitive benefits.

Yoga, Meditation, and Mindfulness

Exploring mind-body practices, Dr. Achary validates the scientific underpinnings of yoga and meditation, previously dismissed as "woo woo" by many.

Dr. Rita Achary [41:23]: "Yoga, meditation... the biological basis is now supported by MRI data."

She explains how these practices enhance neural activity, improve coordination, boost blood flow, and calm regions of the brain associated with anxiety and depression.

The Importance of Sleep and Rest

Dr. Achary emphasizes that sleep is essential for brain maintenance, comparing it to librarians reshelving books in a vast library. She details how adequate sleep facilitates memory consolidation and the clearance of amyloid proteins linked to Alzheimer's.

Dr. Rita Achary [43:41]: "Sleep is the time of the brain where everything gets organized... If you don't sleep, you can't remember, you can't learn."

Additionally, she distinguishes between sleep and rest, advocating for deliberate periods of downtime to rejuvenate the brain and body.

Key Takeaways

At the episode's conclusion, the hosts summarize the essential insights shared by Dr. Achary:

1. Brain as a Hard Drive: As the brain accumulates more memories and experiences with age, cognitive processing may slow down, which is a natural and healthy phenomenon.

2. Balanced Nutrition Over Supplements: Prioritize a well-rounded diet rich in macro and micronutrients for optimal brain health, rather than relying on supplements.

3. Maintain Iodine Intake: Keep a container of iodized salt in the kitchen to prevent iodine deficiency, crucial for thyroid and brain health.

4. Consistent Exercise: Engage in at least 30 minutes of continuous, mild to moderate exercise daily to significantly reduce the risk of memory disorders.

5. Prioritize Sleep and Rest: Ensure adequate sleep and incorporate regular periods of rest to support brain function and overall well-being.

Noah Michelson [47:38]: "Skip the supplements. The best nutrition for brain health is, surprise, a well-rounded diet filled with macro and micronutrients."

Conclusion

The episode wraps up with a reflection on personal practices related to brain health. Raj acknowledges the need to diversify his diet further, while Noah commits to improving his rest habits. Both hosts underscore the profound impact of the episode's insights on their understanding and approach to maintaining a healthy brain.

Noah Michelson [48:17]: "My mind was blown several times in this episode, but actually, I don't think I've been doing it that wrong."

The hosts encourage listeners to apply these strategies to enhance their brain health and invite them to share their experiences via email.
