Green Bananas

Overview

Green (unripe) bananas provide resistant starch, a prebiotic fiber that supports gut microbiome diversity and SCFA production, particularly butyrate. Prebiotic fibres including resistant starch (cooled potatoes, green bananas) support butyrate production and gut barrier integrity.

Substances

4 substances in this food

Acetate

Most abundant SCFA supporting gut barrier integrity and immune regulation

Butyrate

Key SCFA supporting mitochondrial function, gut barrier integrity, and neuroinflammation reduction

Potassium

Electrolyte for nerve transmission, muscle function, and blood pressure regulation

Propionate

SCFA supporting neuroinflammation reduction, blood-brain barrier protection, and neurotransmitter regulation

Preparation Notes

• Consume while still green/unripe for resistant starch
• Can be cooked to increase resistant starch
• Supports gut microbiome diversity
• Part of prebiotic fiber strategy

Biological Target	Substance	Contribution Level	Therapeutic Areas	Mechanism of Action
Gut–Brain Axis & Enteric Nervous System (ENS)	Acetate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses; promotes synthesis of key neurotransmitters such as dopamine and serotonin
Gut–Brain Axis & Enteric Nervous System (ENS)	Butyrate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses; promotes synthesis of key neurotransmitters such as dopamine and serotonin
Gut–Brain Axis & Enteric Nervous System (ENS)	Propionate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses
Inflammation & Oxidative Stress	Acetate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports immune regulation and anti-inflammatory processes
Inflammation & Oxidative Stress	Butyrate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Has anti-inflammatory effects, potentially reducing neuroinflammation; deficiencies linked to many neurological disorders including ADHD
Inflammation & Oxidative Stress	Propionate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Helps reduce neuroinflammation and protects the blood-brain barrier; enhances cognitive function
Mitochondrial Function & Bioenergetics	Butyrate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports mitochondrial function, enhancing brain energy metabolism; aids in reducing cholesterol and neuroinflammation
Neurotransmitter Regulation	Potassium	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Critical for membrane potential, nerve signaling, and neuronal excitability; adequate intake balances sodium effects
Neurotransmitter Regulation	Propionate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Stimulates secretion of norepinephrine and may influence dopamine regulation; promotes synthesis of key neurotransmitters
