Scene: Dr. Kovac’s Clinic – A conversation about diet and memory

Dr. Kovac sits across from Francisco, Joe’s friend from the Café Algarve community, holding a clipboard.

Dr. Kovac:
“Francisco, the brain is like a garden. If the soil is poisoned, the flowers cannot grow. But if you feed it properly, it can recover surprising strength.”

He slides a piece of paper across the desk.

Dr. Kovac’s Brain-Support Diet

Morning

• 🍏 Green apples – rich in polyphenols that support brain cells
• 🥝 Kiwi – vitamin C and antioxidants that help protect neurons

Midday

• 🐟 Sardines – packed with omega-3 fatty acids (DHA), which the brain uses for memory and repair
• 🌰 Walnuts – contain healthy fats and polyphenols linked to cognitive support

Snack

• 🍈 Dried jackfruit – fiber and micronutrients for energy and gut health (the gut influences brain chemistry)

Dessert

• 🫐 Blueberry pie (in moderation) – blueberries are one of the most studied fruits for memory support because of their anthocyanins.

Drinks

• 💧 Spring water from the cooler – hydration is essential for brain function
• 🌱 Basil seed drink – provides fiber and minerals
• 🍍🥥 Pineapple and coconut drink – electrolytes and natural sugars for energy

Dr. Kovac leans back.

Dr. Kovac:
“There have been writers like Eustace Mullins who argued that aluminum cookware contributed to memory diseases like Alzheimer’s disease. His claims are controversial, but the concern about metals in the brain did inspire scientists to study environmental factors.”

He taps the diet sheet again.

Dr. Kovac:
“Modern research doesn’t prove aluminum pots caused Alzheimer’s, but we do know antioxidants, omega-3 fats, hydration, and whole foods support the brain. This diet is about reducing inflammation and feeding your neurons what they need to rebuild connections.”

Francisco smiles.

Francisco:
“So the cure is… sardines and blueberry pie?”

Dr. Kovac laughs.

Dr. Kovac:
“Not a cure, my friend. But it’s a good start for keeping the mind sharp.”

Cilantro (Coriandrum sativum, also called coriander or Chinese parsley) is frequently promoted in alternative health circles as a natural chelator that binds and helps eliminate aluminum and other heavy metals (such as lead, mercury, cadmium, or arsenic) from the body.

This web page, written by a certified holistic nutritionist, presents a list of 10 natural remedies it claims can prevent, treat, and even reverse dementia and Alzheimer’s disease. The article frames these as safer and more effective alternatives to pharmaceutical medications, which it says carry significant health risks.

The ten recommended remedies, in the author’s order of importance, are:

1. Coconut Oil: Promoted as a “magic bullet” due to its ketones, which are described as a powerful brain food that can rebuild nerve linings and improve brain communication.
2. Cinnamon Extract: The article cites research suggesting Alzheimer’s is a form of “type III diabetes” and claims cinnamon extract can help regulate brain insulin activity and prevent the formation of neurofibrillary tangles.
3. Vitamins B, D, and E: It asserts that B vitamins can slow brain shrinkage, vitamin D protects brain cells and helps regenerate neurons, and vitamin E can ease memory loss.
4. Mineral Supplements: The article describes minerals as the “sparks of life” necessary for the brain’s electrical function, recommending liquid colloidal minerals and transdermal magnesium.
5. Omega-3’s: These are said to prevent brain cell damage and lower the risk of developing dementia, with krill oil highlighted as a top source.
6. Build-Up the Immune System: It claims that boosting the immune system can help by keeping the brain’s microglial cells healthy so they can clear out bacteria, viruses, and dangerous deposits.
7. Chlorella and Borax (Boron): These are recommended for chelation, or flushing out heavy metals like mercury and aluminum from the brain and nervous system, which the article identifies as a major cause of dementia.
8. Cholesterol: The article argues that cholesterol is vital for the brain, which is 75% cholesterol by weight, and that statin drugs are dangerous because they deplete the brain of this essential nutrient.
9. Foods to Avoid and Eat: It advises avoiding foods like margarine, refined sugars, gluten, trans fats, and processed dairy, while recommending filtered water, green tea, turmeric, probiotics, and whole foods.
10. Stay Active (Physically and Mentally): It states that both mental stimulation (like puzzles) and physical exercise (especially weight training) are crucial for delaying, improving, and even reversing dementia.

The author concludes that these remedies can produce results within 3-6 months, though a full recovery may take at least 12 months, and recommends a consistent, daily application of these recommendations.

What is 40 Hz?

40 Hz means 40 cycles per second. In neuroscience, it falls within the gamma-frequency range, a pattern of brain activity associated with attention, perception, learning, and coordination between brain regions.

Researchers are studying whether rhythmic light flashes, sounds, or combined audiovisual stimulation at 40 Hz can encourage the brain to produce more gamma activity—a process called neural entrainment. Human studies show that 40 Hz stimulation can produce measurable brain responses, but that is not the same as proving that it “heals” the brain. (NIH)

Why people connect it with brain healing

Much of the interest comes from Alzheimer’s research:

• In mouse studies, 40 Hz light and sound stimulation was associated with reduced amyloid and tau-related pathology and increased activity of microglia, immune cells that help clear cellular debris. (NIH)
• Small human feasibility studies have found that 40 Hz stimulation can be tolerated and can synchronize some brain activity. However, these studies were small and were mainly designed to test safety and feasibility—not to prove a cure. (NIH)
• Some newer studies report possible changes in brain structure or cognition, but systematic reviews conclude that meaningful improvements in cognition and daily functioning remain uncertain. (NIH)
• The National Institute on Aging lists 40 Hz approaches as an area still being studied in clinical trials, rather than an established treatment. (NIH)
