How dietary fibre improves memory and concentration.
Right now your digestive tract, especially your intestines, is colonized by a large magnitude of microorganisms, of which gut bacteria have the bigger portion. We have evolved to have an intimate, symbiotic relationship with these microbes which have actively participated in shaping our evolution.
90% of all known human illnesses can be traced back to an unhealthy digestive system. So we can say for sure that just as disease begins in the gut, so too does health and wellness.
Our intestinal bacteria participate in a wide variety of physiologic actions, including improving your immune system function , detoxification, neurotransmitter and vitamin production such as vitamin B12 that’s essential for iron absorption which protects us from iron deficiency anemia, nutrient absorption, signalling us when hungry or full, and utilizing carbohydrates and fat in our diet.
All of these important processes factor greatly into whether or not we experience allergies, asthma, attention deficit hyperactivity disorder, cancer, diabetes, or dementia. These intestinal bacteria affect our mood, libido, metabolism, immunity, and even the clarity of our thoughts. They also help us determine why were thin or obese, energetic or tired.
Recently published scientific reports have outlined the multiple ways in which brain functioning is influenced by what goes on in the gut. Good gut bacteria are capable of producing important brain chemicals like BDNF, GABA, and glutamate. It’s not only the brain which produces these important chemicals as it was thought before advancements of science in human microbiome.
BDNF( brain derived neurotrophic factor) is involved in neurogenesis which is the formation of new neurons and also protects existing neurons, ensuring their survival and encouraging connections between them. This is essential for thinking, learning, and higher levels of brain function. It is important to note that these good bacteria actually feed on dietary fibre with prebiotics and may be destroyed by junk foods especially in children which has adverse effect on their performance in school.
GABA ( Gamma Amino butyric acid )is an important amino acid chemical messenger in your brain that calms down nerve activity by inhibiting transmissions and controlling increased nerve stimulation. In other words, GABA returns the nervous system to a more stable state so that you can concentrate without anxiety and stress.
Glutamate, yet another vital neuronal chemical messenger that is produced by the gut bacteria, is involved to a larger extent in normal brain function, including cognition, learning, and memory. It’s abundant in a healthy brain. Many cases of neurological challenges, from anxiety and behavioral deficits to depression, Attention deficit and mood disorders and Alzheimer’s disease, have been attributed to a lack of GABA and glutamate.
Fill your kitchen with Prebiotics which are a form of dietary fibre found in leafy vegetables, garlic, onions and fibrous fruits like mangoes and bananas. They feed the good bacteria in your intestines with nutrients like short-chain fatty acids such as butyrate, acetate, and propionate and in turn your gut bacteria reward you with a healthy brain.
