The age-old adage “you are what you eat” holds profound truth. Nearly every molecule in your body is absorbed from what you eat and drink. Your food choices are directly linked to your physical, emotional and social health. And scientists are learning that your gut health and the microbial communities within you have a significant role to play in orchestrating these processes.
The gut microbiome takes the components of food that you cannot digest, like fiber and phytonutrients, and transforms them into signals that regulate how hungry you are, how strong your immune system is, and even how you’re thinking and feeling. It’s as though the communities in your gut microbiome are an orchestra for your health, and you conduct their symphony through food.
I am a gastroenterologist who has spent over 20 years studying how food affects the gut microbiome and overall health. The research is increasingly clear: A gut-friendly approach to nutrition is important for happy and healthy communities both inside and out of your body.
Communities within and without
The fascinating research on the gut microbiome takes us on a journey into the depths of the intestine, where trillions of microorganisms blur the lines between other and self.
The term holobiont describes the combined lives of the microbiome and its vessel, working symbiotically to support each other’s well-being. This relationship is represented at its extreme in the intestines of termites and cows, where microbes transform uniform, low-nutrient diets of wood or grass into complete nutrition replete with vitamins and other essential nutrients for health.
When people eat certain foods, like those rich in fiber, they too harbor similar relationships with their microbiomes. You provide your microbes with food and a safe place to live, and they in turn fortify your diet with vital molecules such as vitamins, short-chain fatty acids and neurotransmitters that are key for regulating your metabolism, immunity and mood.
