An Introduction to Gut Health & Nutrition – 5 Must See Articles

Author: Megan Jones (Adv.Dip.NutMed, BHsc.NutMed)


Addressing our gut seems to be the latest health advice when it comes to improving our overall vitality and wellbeing. And, we would say, for very good reason! Weighing in at around 2kg, and even bigger than the average human brain, our gut microbiome, located within our gastrointestinal tract, has been found to do a lot more than just digest the food we eat.1 In fact, our digestive health has the power to impact all areas of our health, from our brain health and mood, to immunity, inflammation and allergies, and even our metabolism and our ability to maintain a healthy weight.2


Here in our latest blog series on gut health we explore the fascinating world within, uncovering the secrets and science behind nurturing a happy and healthy gut. 


Our five-part blog series includes:



Trusting your gut - understanding the link between gut health & nutrition.


Our gut microbiome is a diverse and dynamic ecosystem of bacteria, fungi, and other microbes, playing a pivotal role in maintaining our health.3 Differences in its composition and therefore function are associated with a variety of chronic diseases, ranging from gastrointestinal inflammatory and metabolic conditions to neurological, cardiovascular, and respiratory illnesses.4


While our gut and brain engage in constant chemical messaging and conversation through the ‘gut-brain axis’,5 this intricate network of communication influences not only our digestion but also our mood, stress levels, and cognitive function as well.6 Our intestines are primary producers of serotonin, which literally means a happy gut makes a happy you!7 It is clear to see why our gut is often referred to as our ‘second brain’!8


Did you know?: Research tells us that our diets and even the environment we live in (both internally and externally) both strongly influence the state of our gut health, through shaping the gut microbiota that inhabit our microbiome.9


It has also been reported that maintenance of a healthy gut microbiota, via nutrition and use of food supplements like Nuzest’s Good Green Vitality, could lead to the reduction of the lifestyle-related metabolic conditions and disease.10

The Gut Connection: How to Improve Your Digestion and Gut Health in 6 Steps


Whilst we cannot use one specific measure for gut health, we do know that smooth and efficient digestion - which is the process through which our body breaks down food, absorbs nutrients, and eliminates waste - plays a key role in our health and well-being.11 By maintaining a healthy gut, we enhance our digestion, ensuring optimal nutrient absorption, nutrient production and the right balance of gut bacteria. Good digestion is arguably the foundation of good health!12


Find out which six steps we recommend to improving your digestion and gut health.



Does Gut Health Affect Your Immune System? | Do These 6 Things


Did you know that over 70% of our immune system resides in our gut?13 A flourishing gut microbiome is key when it comes to immune cell production, a reduction in inflammation, and helping to keep allergies and autoimmune conditions at bay.14


The foods we eat affect the diversity and composition of bacteria in our gut, which in turn affects the immune cells and even the integrity of our gut wall lining, which can determine how susceptible we are to illness.2


Find out which six things we recommend when it comes to gut health and your immune system now!



The Link Between Gut Health & Allergies Plus 5 Top Tips to Help


With so many immune cells residing in our gastrointestinal system, it may not be so surprising to learn that gut health plays a crucial role in the development of allergies.15 A balanced and diverse gut microbiome can not only support and regulate the immune system, but also reduce the likelihood of developing allergies by promoting immune tolerance to harmless substances – think pollen, animal fur or grass.16 In fact, an imbalanced gut microbiome can lead to both increased inflammation and a higher risk of allergic reactions as the immune system becomes more reactive to allergens.17


If you suffer from allergies or if you know someone who does, click here to understand more on the science and the ‘why’ behind these pesky immune reactions!



Probiotics vs. Prebiotics


Despite sounding similar in name, and both playing important roles in restoring the normal gut flora while helping the good bacteria flourish, probiotics and prebiotics both serve very different functions and work in very different ways within our gut.18


If you are curious to find out more about how these live organisms and non-digestible fibres help our gastrointestinal systems to thrive, read on.


This concludes out gut health blog series! Join us next quarter where we’ll be talking about all things healthy ageing.
