What is Gut Health
Gut health doesn't have a clear definition and can mean different things to different people. Here, we define gut health as the well-being of the gut microbiome, which includes everything from your mouth to your colon. This means it involves major organs like the stomach, small intestines, and large intestines, as well as tiny organisms like bacteria and fungi. We've heard the phrase "listen to your gut" for years. Thanks to scientists, this saying now has a literal meaning. Yes, science deserves the credit!
Why do we bother?
Gut health can have impacts on both our physiological and psychological health.
Gut health can have significant physiological impacts across various aspects of our well-being. A healthy gut contributes to:
Efficient digestive function: allowing the body to effectively break down and absorb nutrients
Supporting the immune system: helping to defend against harmful pathogens
Metabolic health: influencing how our bodies manage energy and maintain a healthy weight
Cardiovascular health: as the gut microbiome can impact inflammation and cholesterol levels
Bone health: aiding in the absorption of essential minerals like calcium
Except for the significant impacts on physiological aspects, gut health also has profound psychological impacts.
Mood regulation: producing neurotransmitters like serotonin, dopamine, and GABA, which are essential for mood regulation and mental health; helping to modulate the body's response to stress and reducing the risk of anxiety and depression.
Cognitive functions: Reducing neuroinflammation, benefiting functions such as memory and learning.
Mental health issues: gut health is associated with conditions such as anxiety, depression, and even conditions like autism spectrum disorder (ASD).
The Gut-Brain Connection
The gut-brain connection, often referred to as the gut-brain axis, highlights the intricate communication between our gut and brain. This axis involves the bidirectional flow of signals that influence both digestive and mental functions. The gut microbiota play a crucial role in producing key neurotransmitters that affect our mental state and behaviour. For instance, serotonin, often dubbed the "happy hormone," is primarily produced in the gut and is essential for mood regulation. With serotonin, we are able to constantly feel good! Melatonin, which allows us to sleep well, also has its production linked to gut health. Sweet dreams are gifts from our gut! Dopamine, known for driving motivation and reward, is influenced by gut microbiota. Additionally, epinephrine, or adrenaline, prepares our body for stress and danger, reinforcing the fight-or-flight response. It definitely has the credit for getting us through school exams, presentations, and big events.
What Makes a healthy gut?
A vegan diet can be particularly beneficial for gut health due to its diversity and inclusion of probiotic foods. The wide range of plant-based foods consumed in a vegan diet promotes a diverse gut microbiome, which is essential for a healthy digestive system. The high fibre content in fruits, vegetables, whole grains, nuts, and seeds acts as prebiotics, nourishing beneficial gut bacteria and enhancing their growth. Probiotic foods, which include fermented plant-based foods such as sauerkraut, kimchi, miso, and kombucha, aiding in digestion and improving the balance of the gut microbiota. The combination of diverse, fibre-rich foods and probiotic-rich options in a vegan diet fosters a thriving gut environment, promoting better digestion, enhanced nutrient absorption, and overall gut health.
What Else?
Except for diet, scientists found that other factors could also have major impacts on our gut health, including regular exercise, adequate sleep, mindfulness practice, taking supplements, and so on. There are countless methods for promoting gut health, and one major fact is that we are willing to pay attention and get started! Be aware of your own feelings and be creative to find the way that is most suitable for you in a sustainable way.
Where to Start:
When working towards better gut health, it's important to do it in stages and start small. There is no standard for "the right way of living"; we are always on a journey of exploring and improving. Focus on easy swaps and choose one or two items from the list that are practical for your current lifestyle. By making gradual changes, you can steadily build habits that contribute to long-term health and well-being.
o Increase your fibre intake gradually
o Make sure you chew well and eat slowly
o Use spices like turmeric, cumin, ginger, and black pepper…
o Drink plenty of water
o Read the food labels
o Practice with a community
Do it with Faith and Understanding
Our body itself is already the best physician, no matter the circumstances. We should have faith in this wonderful and free healing system. Trust yourself and your body's ability to heal. Do not let perfection be the enemy of good. "There are no extra brownie points for following the pyramid down to a tee – consistently good is better than occasionally perfect!" By maintaining consistent and healthy habits, you support your body's natural ability to thrive.
