Functions of the brain depend on the transmission of signals between different types of neurons and glial cells, which are mediated by excitatory and inhibitory neurotransmitters. These are glutamate, acetylcholine, and dopamine as well as inhibitory neurotransmitters such as γ-aminobutyric acid (GABA), glycine, and serotonin.
Neurotransmitters are responsible for movement, emotion, learning, and memory. Imbalances of these neurotransmitters can lead to neurological and psychological disorders such as autism spectrum disorder, anxiety disorders, depressive disorders, etc.
Little did you know that these neurotransmitters depend on the bacteria inside our gut!
Microbes in our gut mediate communication among the metabolic, peripheral immune, and central nervous systems via the gut-brain axis.
Certain bacteria in the gut produce enzymes that can facilitate the synthesis of neurotransmitters. These neurotransmitter precursors can pass through the blood-brain barrier to enter the brain where they participate in the cycles of various neurotransmitters
Lactobacillus, bacillus and bifidobacterium are all gut bacteria which contribute to the synthesis of neurotransmitters like dopamine, serotonin and GABA
Changes in dietary habits and environment can lead to changes in gut microbial composition, which subsequently affect neurotransmitter synthesis.
So your cognitive function, and emotional well-being, in the long run, are all going to depend on what you eat.
There are two ways in which you can optimize the good bacteria in your gut and facilitate the optimum functioning of your brain.
One is consuming the right nutrients which will nourish your neurons. The antioxidants in leafy greens and cruciferous vegetables (broccoli, cabbage, and turnips) may be especially protective. Vegetables including beets, broccoli, Brussels sprouts, cauliflower, eggplant, kale, red bell peppers, romaine lettuce, and spinach are good choices. This along with other essential nutrients like omega-3 fatty acids is also equally important.
The second way to promote more good bacteria in the gut is to avoid foods that facilitate inflammation. These mainly include avoiding refined carbs and sugars and unhealthy fats( saturated abs trans fats).
Every aspect of your health revolves around what you eat! Get your food in line for the better!
