The last period of my life is the best. >> These three Nobel Prize-winning scientists lived past 100 years of age. What's their secret?
Their discoveries revealed how brain cells survive, how human cells respond to nutrients, and how the brain stays adaptable for life. In today's video, we will connect the science of Dr Rita Levy Montalchini, Dr Edmund H. Fischer, and Dr torstston visel to everyday foods that support these same longevity pathways showing how protecting the brain at the cellular level may be one of the most powerful ways to stay biologically young.
Dr Rita Levy Montalchini, the molecule that keeps the brain alive. Dr Rita Levy Montalchini lived to 103 years old and won the 1986 Nobel Prize in Physiology or Medicine for her discovery of nerve growth factor, a molecule essential for the survival, repair, and resilience of brain cells. Her work showed that neurons are not simply born and lost, but actively maintained by biological signals that protect them from degeneration.
This discovery fundamentally changed how scientists understand brain aging, revealing that cognitive decline is not inevitable, but strongly influenced by whether the brain receives the signals it needs to stay alive and adaptable over time. Dr Levi Montalchini's discovery of nerve growth factor helps explain why certain foods are especially powerful for brain longevity. One quick thing before we move on.
I send a short email a few days after each video to help these ideas stick in your daily routine. That's through long life notes. The link is below if you want to join.
Three foods stand out notably for supporting neuronal survival and repair. The first is fatty fish rich in omega-3 fatty acids such as DHA. Research published on PubMed and in journals such as the Journal of Neuroscience shows that DHA helps maintain neuronal membrane integrity and supports neuroprotective signaling in aging brains, enhancing pathways linked to nerve growth factor and long-term synaptic health.
The second is berries, particularly blueberries. Studies reported in the journal of agricultural and food chemistry and nutrients show that berry polyphenols modulate neurotrophic factors involved in memory and neuron survival while reducing oxidative stress that interferes with NGF signaling. Human studies also show that blueberry intake can improve brain blood flow and cognitive performance in older adults, reinforcing their role in brain resilience.
The third is extra virgin olive oil. Research published in Frontiers in Aging Neuroscience and indexed on PubMed has found that olive oil polyphenols protect neurons from inflammation and oxidative damage while increasing levels of nerve growth factor and brain derived neurotrophic factor in the brain. Together, these foods create an internal environment where nerve growth factor can do what Dr Rita discovered it was meant to do.
Keep neurons alive, adaptable, and resilient with age. Dr Rita Levi Montalchini's extraordinary longevity was shaped by a lifestyle that closely resembled the traditional Mediterranean way of living she grew up with in Italy. She ate simply and modestly, favoring vegetables, olive oil, legumes, and fish while avoiding excess calories and heavy processing.
This style of eating naturally supports nerve growth factor activity by reducing inflammation and oxidative stress that damage neurons over time. She also remained mentally active well into her late 90s, often saying that the brain thrives when it is continuously used and challenged. Rather than chasing anti-aging trends, she lived by restraint, purpose, and intellectual curiosity.
Her life mirrored her science. Brain cells remain resilient not through extremes, but through steady nourishment, stimulation, and protection over decades. Dr Edmund H.
Fischer, the on andoff switches of life. Dr Edmund H. Fischer lived to 101 years old and won the 1992 Nobel Prize in Physiology or Medicine for discovering reversible protein phosphorilation, the process that allows cells to switch vital functions on and off.
His work showed that cells are not static but constantly adjusting in response to nutrients, energy levels, and environmental signals. This changed how scientists understand aging, revealing that decline is often driven not by simple wear and tear, but by breakdowns in cellular communication. In the brain, these molecular switches are essential for memory, learning, and long-term neuronal survival.
Since Dr Fischer's discovery, researchers have shown that these cellular switches are deeply influenced by diet. As the brain ages, phosphorilation patterns become less precise, disrupting communication between neurons. Studies show that nutrition can shape these patterns.
Diets that reduce metabolic stress help preserve healthy signaling, while poor dietary patterns accelerate dysfunction. Nutrients such as omega-3 fatty acids influence key growth and repair pathways in the brain, helping neurons respond appropriately to stress and maintain synaptic structure. In contrast, diets high in refined sugar and processed fats push these signaling systems out of balance.
In this way, modern research continues to confirm Fischer's insight. What we eat directly affects how long brain cells remain responsive, adaptable, and alive. While foods like extravirgin olive oil, fatty fish, and berries broadly support brain health, the cellular signaling systems Dr Fiser discovered rely especially on nutrients that regulate enzymes and metabolic balance.
Three foods stand out here. The first is eggs, a rich source of choline, B vitamins, and highquality protein. Choline is essential for producing acetylcholine, a neurotransmitter deeply involved in memory and learning.
While B vitamins support the enzyme activity that allows neurons to switch signals on and off, research published in journals such as the American Journal of Clinical Nutrition and Nutrients shows that adequate choline intake supports neurotransmitter synthesis and enzymedriven cellular signaling, helping preserve synaptic function as the brain ages. The second is leafy greens, including spinach, arugula, and kale. Long-term studies reported in neurology and the Journal of Nutrition have found that people who regularly consume leafy greens experience significantly slower cognitive decline.
These vegetables are rich in folate and magnesium, nutrients that play key roles in phosphorilation reactions and cellular communication, helping brain cells respond properly to metabolic and environmental signals. The third is legumes such as lentils, chickpeas, and beans. Research published in journals like the Journal of Gerontology and Diabetes Care shows that legumerich diets improve blood sugar control and reduce metabolic stress, two factors that strongly influence enzyme regulation in the brain by stabilizing glucose and insulin signaling.
Legumes help protect nutrient-sensitive phosphorilation pathways that are critical for long-term neuronal health. Together, these foods support the precise cellular switching system that Dr Fischer helped uncover allowing neurons to stay responsive, adaptable, and resilient well into old age. Dr Torsten Visel, how sensory experience keeps the brain young.
Dr Torstston Visel lived past 100 years of age and won the 1981 Nobel Prize in physiology or medicine for his groundbreaking discoveries on how sensory experience shapes the brain. Through his work on visual processing and neural development, Visel showed that the brain is not hardwired at birth, but remains plastic and responsive to stimulation throughout life. His research revealed that neurons strengthen, reorganize, or weaken based on sensory input, especially vision, laying the foundation for modern understanding of brain plasticity.
This work fundamentally changed how scientists think about aging, demonstrating that sensory engagement is not just important for perception, but essential for maintaining healthy neural circuits, cognitive function, and long-term brain resilience. In interviews given at a very advanced age, Dr Torstston Visel reveals a powerful pattern behind his extraordinary longevity. In his Nobel Prize interview, he speaks repeatedly about lifelong curiosity and how the brain remains flexible and capable of learning well into old age, a principle that mirrors his own life.
In later profiles, including a nature Q&A, he emphasizes deep engagement, passion for meaningful work, and focusing energy on what truly matters rather than chasing distractions. Even after turning 100, he continues to contribute to science through mentoring and supporting education as highlighted by the Nobel Prize Museum. Together, these moments paint a clear picture.
Sustained mental engagement, curiosity, and purpose may be some of the most natural ways to preserve brain vitality across a very long life. When it comes to preserving brain plasticity and sensory health, a different set of foods stands out. Dark chocolate, especially high cacao varieties, is rich in flavonols that enhance cerebral blood flow and support activity dependent synaptic plasticity in visual and sensory regions of the brain.
Human studies show that cocolavinols improve neurovvascular coupling, a key requirement for keeping sensory circuits responsive as we age. Mushrooms, particularly varieties like lion's mane and shiakei, contain bioactive compounds that support nerve regeneration and myelination, processes closely linked to sensory signal transmission and cortical plasticity. Research suggests that herones and arerinos in mushrooms stimulate pathways involved in neuronal growth and connectivity.
Green tea adds another powerful layer to sensorydriven brain plasticity. Rich in kakans such as EGCG, green tea has been shown to enhance synaptic signaling, protect neurons from oxidative stress, and improve attentional processing in the brain. Importantly, green tea supports neurovvascular coupling, allowing active sensory regions to receive blood flow precisely when they are stimulated.
This helps preserve the brain's ability to respond to visual, auditory, and environmental input, reinforcing the kind of experience dependent plasticity that Dr Torstston Vel's work helped uncover. Together, the lives and discoveries of these three Nobel Prize winners show that protecting the brain's ability to adapt, communicate, and repair may be one of the most powerful ways to stay mentally sharp and biologically young well into old page.
