Our digestive system is home to trillions of microbes, which play a vital role in maintaining our overall health. The microbes in our body help break down food, extract vitamins and minerals, and protect us from harmful pathogens.
In recent years, the relationship between the gut microbiome and various illnesses and diseases has been more closely studied and investigated.
This relationship is further explored in the Netflix documentary, ‘Hack Your Health’. This article highlights five important points from the series and helps you better understand how your gut health affects the rest of your mind and body.
1. Everyone has a distinct set of ‘microbial memories’
Every individual’s microbiome is as unique and distinctive as a fingerprint. It is made up of a myriad of personal choices and life encounters. Factors ranging from dietary preferences, travel destinations, exercise routines, stress levels, pets, and even childhood experiences play a significant role in shaping and changing one’s microbiome.
A common misconception is that our gut microbiome is solely affected by the foods we consume. However, in actuality, it is a complex interplay of lifestyle choices that intricately shape our microbial communities.
2. The gut microbiome plays a part in managing weight gain and loss
The gut microbiome, comprising trillions of bacteria living in our intestines, has a significant influence on various aspects of our metabolism and overall health.
One primary aspect is its role in metabolic processes, primarily in how efficiently the body metabolises and stores fats. Certain types of gut bacteria can impact weight gain and loss by affecting the breakdown and absorption of dietary fats, as well as regulating energy expenditure.
Additionally, specific gut bacteria produce short-chain fatty acids (SCFAs), which are crucial in appetite regulation. This is done by influencing the production of hormones that signal hunger and satiety. Therefore, the composition of the gut microbiome can influence our eating behaviours and contribute to appetite control.
It is important to note that the microbiome plays a vital role in nutrient absorption. By breaking down complex carbohydrates, proteins, and fats, gut bacteria aid in the digestion process and facilitate the absorption of essential nutrients, including vitamins and minerals. This not only ensures optimal nutrient intake, but it also impacts an individual’s energy and weight management. The reverse is also true; an imbalance in the gut microbiome can adversely affect one’s health. Imbalanced gut bacteria can trigger chronic low-grade inflammation throughout the body.
This is associated with various metabolic disorders, including insulin resistance. Insulin resistance impairs the body’s ability to regulate blood sugar levels effectively and can lead to weight gain and obesity over time.
3. Each person’s microbiomes can react differently to the same food
Our gut’s microbiome plays a crucial role in the digestive process, contributing to individualised responses to food intake. As mentioned, no two microbiomes are alike (much like a fingerprint), and even when two people consume the same food, their bodies may react differently due to their unique microbial compositions.
The Netflix documentary illustrates this concept through the stories of four different individuals living with distinct food-related issues. As they each consume an apple, their digestive processes vary, affecting the extraction of nutrients and calories from the fruit.
It is important to note that an individual’s metabolic response to a meal, such as fluctuations in blood sugar levels, is closely linked to weight management and can be influenced by the microbiome.
In other words, your microbial composition can help you understand why one person may experience obesity while the other does not, even when they follow similar dietary patterns.
4. People with depression-like symptoms often lack specific bacteria in their gut.
Research has shown a significant link between one’s gut bacteria and specific symptoms resembling depression. It highlights the role of microbial-produced chemicals in influencing brain chemistry.
A study using mice as models compared the microbiomes of individuals exhibiting depression-like symptoms with those of healthy counterparts. Notably, the mice that had gut microbes sourced from healthy individuals displayed more alert and curious behaviours.
In comparison, those with microbiomes from depressed individuals manifested signs of stress, anxiety, and depression. Further investigation revealed alterations in serotonin-related chemicals within both the gut and brain of the depressed mice.
However, when these mice were supplemented with the deficient bacteria, their mood showed a notable improvement. While the depression didn’t completely disappear, it significantly decreased, indicating the potential of targeted microbial interventions in aiding depressive symptoms.
5. Counting calories or avoiding ‘bad’ foods does not create a healthy gut
The aim should be creating a positive relationship with food and adopting a well-rounded diet and lifestyle, as opposed to resorting to restrictive eating habits. Individuals should attempt to promote dietary diversity. This can be done by consuming a wide range of nutrient-rich foods.
Additionally, prioritising whole, nutrient-dense foods over calorie restriction is essential for nourishing both the body and the gut’s microbiome. We should also aim to integrate pre and probiotic-rich foods into one’s diet to further enhance gut health.
Conclusion
Essentially, the Netflix documentary highlights various important factors and links between the gut’s microbiome and how it affects our overall health. By better understanding your gut’s microbiome, you will be able to take the necessary steps towards being the healthiest version of yourself.
