BDNF and Brain Health: How Lifestyle, Nutrition & Movement Support Cognitive Resilience
BDNF and Brain Health: How Lifestyle, Nutrition and Movement Support Learning, Memory & Cognitive Resilience

When people think about brain health, they often focus on memory.
But optimal brain function involves much more than remembering names or where you left your keys.
Healthy brain function influences:
-
Learning
-
Focus
-
Memory
-
Mood
-
Adaptability
-
Long-term cognitive health
One of the most researched factors involved in these processes is a protein called Brain-Derived Neurotrophic Factor (BDNF).
Often referred to as the brain's "growth factor," BDNF plays an important role in the brain's ability to adapt, learn and respond to life's challenges.
Researchers continue to investigate how lifestyle factors such as exercise, sleep, nutrition and stress management influence BDNF and overall brain health.
What Is BDNF?
BDNF stands for Brain-Derived Neurotrophic Factor.
It is a naturally occurring protein found throughout the brain and nervous system.
BDNF is involved in:
-
Supporting neuron survival
-
Promoting communication between brain cells
-
Supporting learning and memory processes
-
Neuroplasticity
Because of these functions, BDNF is often described as one of the key proteins involved in maintaining a healthy and adaptable brain.
What Is Neuroplasticity?
For many years scientists believed the adult brain was largely fixed.
We now know that the brain remains adaptable throughout life.
This adaptability is known as neuroplasticity.
Neuroplasticity refers to the brain's ability to:
-
Learn new skills
-
Form new neural connections
-
Adapt to experiences
-
Reorganise itself throughout life
BDNF is considered one of the important factors involved in these processes.
This means that many aspects of brain health may be influenced by daily lifestyle habits.
Why Brain Health Matters
Brain health influences far more than memory.
It affects:
-
Productivity
-
Mood
-
Decision-making
-
Concentration
-
Emotional wellbeing
-
Quality of life
Researchers continue to investigate how nutrition, movement and lifestyle habits contribute to maintaining cognitive function throughout life.
Factors That Influence Brain Health
Many lifestyle factors are associated with brain function and cognitive wellbeing.
These include:
-
Physical activity
-
Sleep quality
-
Nutrition
-
Social connection
-
Stress management
Rather than relying on a single nutrient or supplement, modern brain health research increasingly focuses on the interaction between these systems.
Exercise: One of the Most Studied Lifestyle Factors
Physical activity is one of the most researched lifestyle strategies associated with brain health.
Researchers continue to investigate the relationship between exercise and BDNF production.
Activities may include:
-
Walking
-
Cycling
-
Swimming
-
Resistance training
-
Interval training
Regular movement contributes to overall health and wellbeing and is often included in brain-health recommendations.
Sleep and Brain Function
Sleep is one of the most important yet often overlooked aspects of brain health.
During sleep, the brain continues numerous processes involved in:
-
Memory consolidation
-
Learning
-
Recovery
-
Neural communication
Poor sleep is associated with reduced cognitive performance, reduced concentration and impaired learning.
Prioritising sleep remains one of the most effective lifestyle strategies for long-term brain health.
Nutrition and Brain Health
The brain requires a continuous supply of nutrients to function optimally.
Balanced dietary patterns that emphasise:
-
Vegetables
-
Fruit
-
Fibre-rich foods
-
Healthy fats
-
Quality protein sources
are commonly associated with overall health and wellbeing.
Researchers continue to investigate how dietary quality influences cognitive function across the lifespan.
The Gut–Brain Connection
The gut and brain communicate through a complex network known as the gut–brain axis.
Researchers continue to investigate how the gut microbiome influences:
-
Immune activity
-
Brain function
-
Mood
-
Overall wellbeing
This growing field highlights the interconnected nature of human health.
Rather than viewing the brain in isolation, modern science increasingly recognises the importance of supporting the entire system.
Where Bone Broth Fits
Bone broth is a traditional whole food that provides protein together with collagen-derived amino acids.
A serve of Broth & Co Bone Broth provides approximately 5g of naturally occurring protein.
Bone broth naturally contains:
-
Glycine
-
Proline
-
Hydroxyproline
-
Glutamine
These amino acids contribute to the distinctive nutritional profile of collagen-rich foods.
At Broth & Co, bone broth is used as a convenient whole-food option that can contribute to:
-
Daily protein intake
-
Dietary variety
-
Digestive wellbeing
-
Healthy ageing nutrition
-
Active lifestyle nutrition

The Broth & Co Clinical Study
Broth & Co Bone Broth Powder is supported by a published clinical study.
The study investigated daily bone broth consumption over eight weeks and evaluated markers associated with intestinal permeability and digestive wellbeing.
One of the outcomes measured was the mannitol:lactulose ratio, a recognised research marker used in the assessment of gut barrier function.
Participants demonstrated improvements in this marker during the study, together with improvements in digestive wellbeing outcomes.
These findings contribute to growing interest in how nutrient-dense foods may fit within broader digestive health strategies.
Chronic Stress and Cognitive Wellbeing
Stress is a normal part of life.
However, prolonged stress may influence numerous systems throughout the body including:
-
Sleep
-
Mood
-
Recovery
-
Physical health
-
Cognitive wellbeing
Strategies that may support resilience include:
-
Physical activity
-
Time outdoors
-
Mindfulness practices
-
Social connection
-
Adequate sleep
Small, consistent habits often have the greatest long-term impact.
Metabolic Health and the Brain
The brain is an energy-demanding organ.
Researchers continue to investigate the relationship between:
-
Physical activity
-
Cognitive function
This is one reason balanced nutrition, adequate protein intake and regular movement are often recommended as part of broader wellbeing strategies.
