The gut microbiome is an exciting area in medical research, linked to everything from metabolic to mental health.
The microbiome is the community of microorganisms that exist in our bodies, covering us from head to toe, with the colon being the most densely concentrated area.
The genetic material of these microbes is referred to as the microbiome, and they have 200 times more genetic material than humans.
We are less than 1% human in terms of DNA, with about 38 trillion microbes in the colon alone, making us a superorganism.
The gut microbiome consists mainly of bacteria, but also includes fungi, yeasts, and archaea, with the gut microbiome being the most complex and interesting due to its interaction with the food we eat.
From an evolutionary perspective, humans have coexisted and co-evolved with microbes from the very beginning, relying on them for survival and thriving.
The gut microbiome plays a central role in human health, supporting digestion, metabolism, immunity, hormone balance, mood, brain health, and genetic expression.
The microbiome was not recognized as an essential organ until about 20 years ago due to limitations in studying anaerobic microbes and making assumptions about their significance.
Manipulation of the gut microbiome can have powerful effects on the body, such as in autoimmune conditions like lupus or Crohn's disease, where dysbiosis occurs - a loss of balance within the microbiome, with an increase in bad microbes and damage to the intestinal lining.
Studies show that fecal transplants in combination with cancer therapy lead to better outcomes, while antibiotics can harm the microbiome and worsen cancer therapy.
The over-utilization of antibiotics is a problem, leading to negative effects on the gut microbiome and creating resistance to antibiotics. Antibiotics should be reserved for situations where they are truly needed.
Studies show that the gut microbiome plays a crucial role in body shape and metabolism, challenging the calories in calories out paradigm.
The baby starts forming its microbiome before birth, and exposure to microbes begins when the barrier separating the external world from the baby is removed.
Breast milk contains human milk oligosaccharides, which act as prebiotics, fueling the developing gut microbiome in newborns.
Breastfeeding enhances specific species of microbes, and the introduction of solid food accelerates the variety of species within the child's microbiome.
The formative years from birth to age two to three are critical for microbiome development, and factors like cesarean section, bottle feeding, and antibiotics during this time can lead to increased likelihood of metabolic diseases and immune-mediated issues later in life.
The gut microbiome is forgiving and wants to have a healthy relationship with you, reflecting your environment, including nutrition, sleep, exercise, and relationships with others.
Changes in diet can lead to changes in the gut microbiome in less than 24 hours, showing its malleability.
Research shows that people share more microbes with their spouse than with their siblings, emphasizing the impact of close relationships on gut microbiome.
Partners who feel emotionally connected share more microbes together than distant partners. Social creatures share microbes through normal human behavior like kissing or handshakes.
Stress can disturb the gut microbiome, leading to digestive symptoms. Unsettled issues or trauma can trigger stress response, hindering overall well-being.
Three key dietary tips for gut health: increase plant food consumption, eat a wider variety of plants, and consume more fermented foods.
The gut microbiome is a crucial organ, with scientific evidence showing its impact on weight, development, and overall health.
Factors beyond food, such as sleep, exercise, and social interactions, also influence the gut microbiome and overall well-being.
Nature has decided that we are the best version of ourselves as superorganisms when we have a healthy relationship with our gut microbiome. We really knew nothing about this relationship until very recently. But now we are finally empowered with a new knowledge and new science that is transforming our ability to nurture that relationship and bring out the best in all of us.
