Can Brain Food, Mathematics, and Mental Exercise Help Preserve Intelligence for Life?

 

Feeding the Brain and Exercising the Mind

Can Brain Food, Mathematics, and Mental Exercise Help Preserve Intelligence for Life?


by: lim ju boo -  lin ru wu (ζž— 如 ζ­¦)


My brother-in-law, Er. Ong Geok Soo, a senior structural engineer working in Singapore in our WhatsApp chat group is constantly teasing me about my drinking goat's brain soup and eating cow's brain - about the lengthy articles I write in this blog he pretended he could not understand, and that it is too late now for him to follow me by eating pig's brain or drinking goat's brain soup. 

Consumption of whether cow's or goat's brains too has their health benefits. 

Let me tell my story that's  not too complicated for my brother-in-law to follow and understand.  

 In my younger days as a child, my mother often prepared steamed brain soup with medicinal herbs for me. Later, during my early working years, I regularly visited a small Indian food shop behind a Chettiar money lender’s shop in Jalan Lebuh Ampang (Ampang Street) in Kuala Lumpur where I enjoyed goat’s brain cooked with eggs and curry for lunch, and I did this almost everyday for years.

Interestingly, despite consuming foods that many people fear because of their high cholesterol content, whether brains and eggs—my blood cholesterol levels were never elevated when I asked my colleagues at the Institute for Medical Research where we worked together to analyse my blood. The reasons why foods rich in cholesterol do elevate blood cholesterol as most people would have thought, involve quite a bit of biochemistry, and I don't think I should write and explain them, else this will deviate from what I intend to write here.   

This personal experience led me to a lifelong question: can eating animal brains, eggs, and other so-called “brain foods” actually improve intelligence, memory, and learning power, especially when consumed during childhood when the brain is still developing?

At the same time, another equally important question arises: does “using the brain” through mathematics, problem-solving, and games like chess strengthen intelligence and memory in the same way physical exercise strengthens muscles?

Modern science suggests that the answer to both questions is yes, but with an important distinction. Nutrition helps build and maintain the brain, while mental exercise trains and strengthens it. Together, they form one of the most powerful combinations for lifelong cognitive health.

Many traditional cultures believed that eating certain organs nourished the same organ in the human body. Liver was eaten for liver strength, bone broth for bones, and brains for intelligence. While this may sound like folklore, neuroscience reveals that there is some scientific truth behind it.

Animal brains, whether from goats, cows, or other animals and eggs are exceptionally rich in nutrients essential for brain function, particularly choline, cholesterol, phospholipids, and omega-3 fatty acids such as DHA. These are not merely food; they are fundamental building materials for the brain itself.

One of the most important nutrients found in eggs and brain tissue is choline. Choline is the precursor for acetylcholine, one of the brain’s most important neurotransmitters. Acetylcholine plays a major role in memory formation, concentration, attention, learning, muscle control, and communication between nerve cells. Without sufficient choline, the brain struggles to form and transmit signals efficiently.

Choline is also essential for building cell membranes and for myelination, the process by which nerve fibers are insulated so that electrical signals travel faster and more efficiently. In simple terms, choline helps both the hardware and the wiring of the brain. This is one reason eggs are often called one of nature’s best brain foods.

Cholesterol is another misunderstood but essential brain nutrient. Many people fear cholesterol, but the brain tells a different story. In fact, the human brain contains about twenty-five percent of the body’s total cholesterol. This is because cholesterol is vital for maintaining the structure of neurons, building synapses between nerve cells, supporting synaptic plasticity, producing hormones, and insulating nerves.

Synaptic plasticity is especially important because it represents the brain’s ability to adapt, learn, and form new memories. Without cholesterol, the brain cannot function properly. This does not mean excessive dietary cholesterol is always beneficial, but it reminds us that cholesterol itself is not the enemy, it is an essential biological necessity.

Animal brains also contain valuable compounds such as phosphatidylserine and DHA. Phosphatidylserine is a phospholipid important for maintaining healthy brain cell membranes and improving communication between neurons. DHA, a major omega-3 fatty acid found in brain tissue, supports memory, mood, cognitive development, and protection against age-related decline. These substances help preserve the fluidity and function of brain cells, much like good oil keeps an engine running smoothly.

The first one thousand days of life, from conception to about two years of age, represent the most critical window for brain development. During this period, nutrients like choline and DHA have their greatest lifelong impact. They support the rapid growth of the hippocampus, which is the brain’s memory center, and they help form neural pathways that influence long-term learning capacity, language development, attention span, and emotional regulation.

Studies have shown that children who receive sufficient animal-sourced foods such as eggs, milk, and meat often demonstrate improved cognitive scores, better school performance, larger head circumferences which are markers of healthy brain growth—and stronger verbal and performance IQ scores. This does not mean these foods create genius, but rather that they provide the necessary construction materials for a developing brain. A strong house needs good bricks that my brother-in-law, as a structural engineer will agree, and  a strong and intelligent brain needs good nutrition that all nutritionists too concur. 

However, eating goat’s brain does not magically transfer the goat’s intelligence to a person. It simply provides nutrients that support brain development and maintenance. It is similar to giving a carpenter high-quality tools; it does not automatically make him a master craftsman, but it gives him the best chance to perform well. Nutrition creates potential; practice develops ability.

This brings us to the second half of intelligence about exercising the brain.

A well-fed brain still needs training. This is where mathematics, chess, logic puzzles, reading, and deep thinking become essential. Just as muscles weaken without use, the brain also declines when left unstimulated.

Mental activity strengthens the brain through a remarkable process called neuroplasticity. Neuroplasticity is the brain’s ability to reorganize itself by forming new neural connections throughout life. In short, the brain rewires itself according to how we use it.

Mathematics, that has always been one of my pet subjects since a young child is one of the best forms of cognitive exercise. It demands logical reasoning, abstraction, memory, concentration, pattern recognition, and step-by-step problem solving. When solving mathematics problems, the prefrontal cortex—the area responsible for working memory and logical thinking, is highly activated.

Consistent mathematical practice improves working memory, cognitive flexibility, analytical thinking, attention span, and problem-solving ability. Some studies even suggest that regular mathematical engagement can increase gray matter density in certain brain regions. In simple terms, mathematics strengthens the “thinking muscles” of the brain.

Revisiting old school mathematics textbooks later in life - as I sometimes do - for fun,  can be surprisingly powerful. Trying once again to solve equations we learned in our youth forces the brain to retrieve forgotten pathways, much like reopening old roads that had become overgrown. This is not merely nostalgia—it is mental rehabilitation.

Chess provides another excellent form of mental exercise and is often called “calisthenics for the mind.” It requires planning ahead, remembering previous moves, predicting future possibilities, visual pattern recognition, and concentration under pressure.

Chess players often demonstrate stronger working memory and improved pattern recognition. Some studies also show improved auditory memory and slower cognitive decline in older adults who regularly engage in strategic games. Chess teaches the brain to think before acting, a valuable skill both on and off the chessboard.

Can these habits help prevent Alzheimer’s disease? Perhaps not completely prevent it, but they may certainly help reduce the risk and delay its onset.

Regular mental exercise helps build what scientists call cognitive reserve. This means the brain develops extra neural pathways that help compensate when aging or disease begins to damage brain tissue. Activities such as mathematics, chess, reading, learning languages, music, writing - just like I do now, puzzles, and social engagement even as I actively do in  my WhatsApp chat - all of which I normally occupy my time, can help delay the onset of dementia symptoms and reduce the severity of cognitive decline.

Even in old age, the brain still responds to challenge. It is never too late to teach an old brain new tricks.

The most powerful approach is not food alone - such as eating cow's, goat's or pig's or even monkey's brain - as Chinese do with monkeys,  or drinking goat's  soup - as my brother-in-law constantly make fun of me - which he said is too late for him to follow me now -  or mental exercise alone, but both working together

Imagine a student who eats nutritious meals rich in eggs, fish, and healthy proteins while regularly studying mathematics and developing disciplined thinking. Or imagine an elderly person who revisits old textbooks, solves forgotten school day's maths equations, plays chess, reads deeply, and maintains strong social connections. This combination nourishes the brain biologically and strengthens it functionally.

It supports memory, clarity, resilience, and dignity in aging. Perhaps it may even help reduce the fear of senility, dementia, and the devastating condition known as Alzheimer’s disease.

We spend great effort maintaining our cars, houses, and finances. Yet the most valuable organ we possess is our brains — the very seat of memory, intellect, thought, identity, and wisdom. It deserves both proper nutrition and regular exercise.

Perhaps our elders were wiser than we realized when they insisted on eggs for breakfast, brain soup for strength, and discipline in mathematics. Maybe they understood something modern science is only now explaining:

You, as my blog articles reader - do not only become what you eat.

You also become what you repeatedly think.

Feed the brain.

Exercise the mind.

Protect the memory.

And perhaps, in doing so, protect the person like you and me. 

I hope this is a nourishing thought for our brains - even right now,  and simple to understand that would be worth my time and effort enjoying writing here.

Two Paralleled Worlds


 

Two Worlds: One of Humans, One of Animals


by lim ju boo

 

Imagine, dear friend, that the Earth is divided into two parallel worlds.

Both worlds receive the same sunlight from the same faithful sun. Both have rivers flowing, rain falling, oceans breathing, forests growing, mountains standing, and fertile soil waiting to nourish life.

But there is one great difference.

In the first world, there are only humans.

In the second world, there are only animals.

No humans exist there.

Let us walk through both worlds and see what becomes of them.

 

World One: The Kingdom of Humans Alone

At first, this world appears magnificent.

Cities rise rapidly. Towers of glass and steel stretch toward the heavens. Roads spread like veins across the land. Machines roar. Factories breathe smoke. Ships cross the oceans. Aircraft cut through the skies.

Humans, gifted with intelligence, ambition, and invention, quickly transform the landscape.

Forests are cut for timber and land development.

Mountains are broken for minerals and metals.

Rivers are dammed and redirected.

Oil is pumped from the deep earth.

Coal is burned.

Gas is extracted.

Concrete replaces soil.

Plastic replaces wood.

Steel replaces stone.

The human world becomes efficient, productive, and powerful.

Food is no longer hunted, it is manufactured.

Animals are absent, so humans create artificial systems for pollination, pest control, and ecological balance, often at enormous cost.

The silence of birds is replaced by engines.

The songs of insects are replaced by electricity.

The night sky dims beneath artificial lights.

For a while, humans celebrate their triumph.

They call it progress.

They call it civilization.

But slowly, invisible cracks begin to appear.

Without animals, ecosystems collapse.

No bees mean poor pollination.

No worms mean poor soil renewal.

No birds mean uncontrolled insect populations.

No predators mean ecological imbalance.

The food chain breaks.

The soil weakens.

The rivers become sick.

The oceans fill with waste.

Air becomes harder to breathe.

Climate becomes unstable.

Floods become stronger.

Droughts become longer.

Storms become angrier.

And then comes the cruel truth:

Humans were not masters of nature.

They were only one thread in a great living tapestry.

As resources shrink, humans compete.

Competition becomes conflict.

Conflict becomes war.

Weapons evolve faster than wisdom.

Missiles replace dialogue.

Drones replace diplomacy.

The same intelligence that built cities now perfects destruction.

Eventually, the world of humans begins to consume itself.

Not because humans were evil—

but because intelligence without restraint becomes hunger without end.

This world may survive for centuries, perhaps millennia.

But unless humans rediscover humility, stewardship, and balance, their own brilliance may become the architect of their downfall.

Their greatest enemy was never nature.

It was themselves.

 

World Two: The Kingdom of Animals Alone

Now let us step into the second world.

There are no cities.

No factories.

No roads.

No banks.

No governments.

No wars.

No machines.

Only life.

The forests stand ancient and undisturbed.

Rivers run clear like crystal veins.

The oceans pulse with fish and whales.

Birds fill the skies.

Insects hum their endless work.

Predators hunt.

Herbivores graze.

Scavengers clean.

Worms rebuild the soil.

Fungi quietly recycle death into life.

Nothing is wasted.

Nothing is manufactured.

Nothing is hoarded.

Animals kill, yes—but only for food, survival, or defense.

A lion does not kill ten zebras for entertainment.

A wolf does not poison a river for profit.

An elephant does not destroy a forest to build a palace.

Nature operates with severe simplicity.

Life feeds life.

Death feeds life.

Balance governs all.

There is suffering, certainly.

There is hunger.

There is disease.

There is competition.

But there is no greed.

There is no ambition to dominate the entire planet.

There is no ideology.

There is no nuclear weapon.

There is no pollution made for convenience.

The Earth heals itself continuously.

Fallen trees become homes.

Dead animals become nourishment.

Waste becomes renewal.

The system is imperfect, but it is self-correcting.

This world could continue not for centuries—

but for millions of years.

As long as the sun shines, rain falls, and plants grow, life continues.

Not peacefully, perhaps—

but sustainably.

Not comfortably—

but truthfully.

 

The Great Lesson

The irony is profound.

The creature with the highest intelligence became the greatest danger to its own home.

The creatures with no universities, no philosophy, and no technology preserve balance far better.

Animals live within nature.

Humans often try to live above it.

That is the difference.

The tragedy is not that humans are powerful.

The tragedy is that humans often mistake power for wisdom.

Yet there is still hope.

Because humans also possess something extraordinary:

the ability to reflect,

to repent,

to choose,

and to change.

A tiger cannot become moral.

A human can.

A whale cannot write laws to protect the ocean.

A human can.

A bird cannot plant a forest for the future.

A human can.

Thus humans are not merely the most destructive creatures—

they are also the only creatures capable of consciously becoming guardians.

The same hand that destroys can also heal.

The same mind that invents weapons can invent peace.

The same species that wounds the Earth can also restore it.

 

Perhaps the Creator did not give humans dominion to dominate—

but responsibility to protect.

If humans forget this, World One will end in ashes.

If humans remember this, World One may yet become as beautiful as World Two.

And perhaps that choice—

more than intelligence itself—

is what truly defines humanity.

"And God said, Let us make man in our own image, after our likeness: and let them have dominion over the fish of the sea, and over the fowls of the air, and over the cattle, and over every creeping thing that creepth upon the earth"

(Genesis 1:26) 

This verse represents the creation of humanity on the sixth day, emphasizing a unique relationship between God, humans and all creatures on earth for human survival by granting humans consciousness and reasoning and

sacrificing animals only for food

From Fire to Fallout: The Ascent, Burden and Fall of Homo sapiens


 https://scientificlogic.blogspot.com/2026/04/from-fire-to-fallout-ascent-burden-and.html 


Humans today no longer reflect the perfect, unblemished image of God as they did when first created, a purity lost when the serpent deceived Eve in the Garden of Eden.  

In my closing thought, let me refer to this verb Jesus predicted in His Sermon on the Mount:

"The meek shall inherit the earth"

(Matthew 5:5)

When humans destroys themselves as the last to appear, but the first to disappear from the surface of this earth through their own greed, technology and weapons of mass destruction, the meeker, humbler, and more primitive creatures that were the first to evolve or created to colonize this planet, they shall once again regain their inheritance of their only home. 

Jesus also said:  

"Blessed are the barren, and the wombs that never bore"

(Luke 23:29).  


Wasn't not Jesus right?  


Suppose, dear friends and readers, if you were to chose between these two contrasting worlds - in a Garden of Eden among animals, or in concrete jungle 


among only humans with no  animal around, which world would you chose to stay?  Write me your opinion and comments to  share. Thank you.

When the Wells Run Dry: Energy and Motion Are Crippled, the Humble Bicycle Takes Over

 

When the Wells Run Dry: Energy and  Motion Are Crippled, the Humble Bicycle Takes Over.

I have written several articles concerning about how the closure of the Straits of Hormuz affects the global flow and prices of oil. I have written about the rise and fall of mankind. I have also written the bicycle as mankind greatest invention. The last article I wrote was what will happen when the last drop of oil runs dry. Here are the links:

https://scientificlogic.blogspot.com/2026/04/from-fire-to-fallout-ascent-burden-and.html


https://scientificlogic.blogspot.com/2026/04/the-bicycle-is-greatest-invention-ever.html

 

https://scientificlogic.blogspot.com/2026/04/when-last-drop-runs-dry-quiet.html

 

Let me go back to the bicycle  as our greatest of inventions when we face a crisis. 

There are moments in history when humanity is quietly advised to reconsider its path, and others when circumstances compel it to do so. The rising cost of petrol in recent times, exacerbated by tensions in the Middle East and the vulnerability of the Strait of Hormuz belongs to the latter. It is not merely a fluctuation in price; it is a reminder of how deeply our civilization depends on a resource that is finite, fragile, and unevenly distributed.

For more than a century, oil has been the unseen force behind modern life. It moves our vehicles, sustains global trade, and forms the basis of countless materials that surround us. Yet oil is not a gift that renews itself within human timescales. It is the compressed residue of ancient life, accumulated over millions of years and consumed within a few generations. When supply is threatened, as it is now, the illusion of permanence dissolves quickly.

Nowhere is this dependence more evident than in transportation. Our cities are designed for cars, our distances defined by speed, and our habits shaped by the assumption that fuel will always be available. But what happens when that assumption begins to fail?

To answer this, it is helpful to step back and examine a simple yet profound comparison between the motorcar and the bicycle.

A litre of petrol contains an astonishing amount of energy, approximately 34 million joules. In a typical car, this single litre can carry a person about 12 to 15 kilometres, depending on efficiency and driving conditions. At first glance, this seems impressive. Yet the internal combustion engine is inherently inefficient; much of that energy is lost as heat, noise, and friction. Only a fraction is converted into useful motion.

In contrast, the human body, though far less powerful, is remarkably efficient when paired with a bicycle. A person cycling at a moderate pace expends roughly 100 to 150 watts of power. Over the course of an hour, this translates to about 400,000 to 500,000 joules of energy. With this modest expenditure, a cyclist can travel 15 to 20 kilometres.

If we compare these figures carefully, a striking truth emerges. The energy contained in a single litre of petrol is enough, in principle, to propel a bicycle hundreds of kilometres if it could be converted with similar efficiency. Instead, when used in a car, it moves a much heavier machine only a fraction of that distance.

The bicycle, therefore, is not merely a simple device; it is one of the most efficient energy converters ever devised. It transforms human metabolic energy into motion with minimal loss, extending our natural capacity many times over. In terms of energy per kilometre per person, it far surpasses the automobile.

This comparison is not intended to diminish the usefulness of cars, which have undoubtedly transformed society. Rather, it highlights the imbalance that has developed. We have come to rely on a system that consumes immense energy for relatively modest gains in mobility, while overlooking alternatives that are elegant, efficient, and sustainable.

Before the age of oil, movement was slower, but it was also more balanced. People walked, cycled, or relied on simple mechanical and animal-powered systems. Distances were meaningful, and communities were often more localized. Today, while we cannot and should not abandon the advantages of modernity, we may need to recover some of that balance.

The bicycle offers a compelling path forward. It is accessible, affordable, and independent of fossil fuels. In urban environments, it can often rival or even surpass cars in efficiency and speed, especially when congestion is considered. For longer distances, it can be integrated with public transport systems, forming a hybrid model of mobility that is both practical and sustainable.

Beyond human-powered transport, we must also look to the natural forces that surround us. The wind that turns turbines, the sunlight that falls freely upon the Earth, and the flowing water that descends from higher ground, all represent sources of energy that do not diminish with use.

These renewable energies may not yet fully replace fossil fuels, but they offer a direction, one that is not constrained by depletion or geopolitics. Unlike oil, they are not concentrated in a few regions of the world; they are distributed, abundant, and continuously replenished.

The present crisis, therefore, is more than an economic challenge. It is an invitation to rethink our assumptions about energy, mobility, and progress itself. Must we always move faster, farther, and with greater consumption? Or can we learn to move wisely, efficiently, and within the limits of what the Earth can sustain?

In the quiet turning of a bicycle wheel, there is a lesson. It reminds us that progress need not always be complex, that power need not always be vast, and that sometimes the most enduring solutions are those that is in line closely with the natural capacities of the human body and the rhythms of the world around us.

When the wells of oil one day run dry, and that day will surely come—it may not be the most advanced machines that carry us forward, but the simplest ones, guided by deeper understanding.

And perhaps, to my gentle readers, that is not a step backward, but a step toward wisdom.
