The Science of Inflammaging: How Diet, Movement & Gut Health Influence Healthy Ageing
The Science of Inflammaging: How Diet, Movement & Gut Health Influence Healthy Ageing
We often think of ageing as something that simply happens over time.
However, scientists now understand that ageing is influenced by many interconnected biological processes.
One of the most widely discussed is a concept known as inflammaging.
Inflammaging describes the low-grade, chronic inflammation that can gradually develop as we age.
Unlike the short-term inflammation that helps the body heal after injury or infection, inflammaging occurs at a much lower level and may persist for years.
Researchers believe this process is influenced by many factors, including:
• Diet
• Physical activity
• Sleep
• Body composition
• Gut health
• The microbiome
• Environmental exposures
The encouraging news is that many of these factors are influenced by everyday habits.
What Is Inflammaging?
The term inflammaging combines two words:
Inflammation + Ageing
It describes the gradual increase in inflammatory activity that can occur as people get older.
Scientists believe inflammaging is one of several biological processes associated with ageing and may influence many aspects of long-term health.
Importantly, inflammaging is not considered a disease.
Instead, it is viewed as part of the complex interaction between the immune system, metabolism, lifestyle and environment over time.

Inflammation Isn't Always Bad
The word inflammation often carries negative connotations.
In reality, inflammation is an essential part of normal health.
Acute inflammation helps the body:
• Respond to infection
• Repair damaged tissues
• Recover after exercise
• Heal wounds
Without inflammation, the body would struggle to defend itself.
The goal is not to eliminate inflammation altogether.
The goal is maintaining balance.

Why Does Inflammaging Occur?
Researchers believe inflammaging develops through multiple pathways rather than a single cause.
Contributors may include:
Changes in Immune Function
The immune system changes throughout life, influencing how the body responds to challenges.
Reduced Physical Activity
Less movement often leads to declines in muscle mass and metabolic health.
Changes in Body Composition
Excess visceral fat may contribute to inflammatory activity.
Poor Sleep
Sleep is increasingly recognised as a major regulator of immune and metabolic health.
Highly Processed Dietary Patterns
Diets lacking nutrient diversity may negatively influence the microbiome and metabolic wellbeing.
Changes in the Gut Microbiome
The composition of the microbiome naturally evolves throughout life.
Together, these factors can contribute to the biological environment associated with inflammaging.

The Gut Microbiome and Inflammaging
One of the most exciting areas of healthy ageing research involves the gut microbiome.
The trillions of microorganisms living within the digestive tract interact with:
• The immune system
• Metabolism
• The gut barrier
• The brain
• Nutrient metabolism
Researchers increasingly recognise that microbiome diversity may play an important role in healthy ageing.
Dietary patterns rich in:
✔ Vegetables
✔ Fruit
✔ Legumes
✔ Whole grains
✔ Herbs and spices
tend to support greater dietary diversity and help nourish beneficial microbes.
Rather than focusing solely on probiotics, many experts now believe that feeding the microbiome through diverse plant foods may be equally important.

Muscle: The Forgotten Organ of Healthy Ageing
When people think about healthy ageing, they often focus on wrinkles or bone health.
Yet muscle may be one of the most important tissues to protect throughout life.
Muscle helps support:
• Strength
• Mobility
• Balance
• Physical independence
• Metabolic health
• Glucose regulation
Because muscle is metabolically active, maintaining muscle mass becomes increasingly important as we age.
This is why nutrition experts frequently emphasise:
✔ Adequate protein intake
✔ Resistance training
✔ Regular movement
✔ Recovery
Building muscle isn't only about athletes.
It supports function, resilience and quality of life throughout adulthood.

Mitochondria, Energy and Ageing
Mitochondria are often referred to as the body's cellular powerhouses.
They help convert nutrients into usable energy and support countless biological functions.
Researchers are increasingly exploring how mitochondrial health may influence:
• Energy production
• Physical performance
• Cognitive function
• Healthy ageing
This growing field highlights the importance of lifestyle habits that support overall cellular health.
Nutrition, exercise, sleep and metabolic health all influence mitochondrial function.

Foods Associated with Healthy Ageing
There is no single anti-ageing food.
Instead, healthy ageing is generally associated with dietary patterns rich in nutrient-dense whole foods.
Colourful Vegetables
Provide fibre, vitamins and plant compounds.
Fruit
Contributes antioxidants and dietary diversity.
Legumes
Provide fibre and plant protein.
Herbs and Spices
Add flavour and naturally occurring plant compounds.
Omega-3 Rich Foods
Commonly included in healthy dietary patterns.
Quality Protein
Supports muscle maintenance and recovery.
Fermented Foods
Can contribute to microbiome diversity.
Bone Broth
Provides protein and collagen-derived amino acids.
These foods are often found in dietary patterns such as the Mediterranean Diet, which is frequently associated with healthy ageing and metabolic wellbeing.

Where Bone Broth Fits
Bone broth is not a magic solution for ageing.
However, it can be incorporated into a nutrient-dense dietary pattern.
Bone broth naturally provides:
• Protein
• Glycine
• Proline
• Hydroxyproline
• Glutamine-containing proteins
It also serves as a versatile base for vegetable-rich meals and soups.
Using bone broth in meals that contain colourful vegetables, legumes, herbs and spices can help create nutrient-dense eating patterns that support overall wellbeing.

Practical Habits That May Support Healthy Ageing
The strongest healthy ageing strategies are often the simplest.
Move Daily
Walking, gardening and regular activity all contribute.
Build and Maintain Muscle
Resistance training supports strength and function.
Eat More Plants
Aim for variety and colour.
Prioritise Protein
Protein supports muscle and recovery.
Sleep Well
Sleep plays an important role in immune and metabolic health.
Manage Stress
Long-term stress can affect multiple body systems.
Stay Connected
Social connection is increasingly recognised as a pillar of healthy ageing.

Healthy Ageing Is Built Daily
One of the most important lessons from inflammaging research is that healthy ageing is rarely determined by a single nutrient, supplement or habit.
Instead, it reflects the cumulative effect of daily choices made over many years.
Nutrition, movement, sleep, muscle mass, metabolic health and gut health all work together to influence long-term wellbeing.
The goal is not perfection.
It is consistency.
Final Thoughts
Inflammaging is one of the most fascinating concepts in modern healthy ageing research.
While scientists continue to investigate the biological mechanisms involved, the practical takeaways remain remarkably simple.
A lifestyle built around:
✔ Nutrient-dense foods
✔ Diverse plant foods
✔ Quality protein
✔ Movement
✔ Sleep
✔ Gut health
may help support healthy ageing and overall wellbeing.
At Broth & Co, we believe these foundations remain the most powerful tools available for long-term health.
By focusing on real food, movement, recovery and consistency, healthy ageing becomes something we actively support every day—not something we simply hope for in the future.
