Barley

Overview

Barley provides beta-glucan prebiotic fiber and whole grain nutrients, supporting gut microbiome diversity and stable glucose release. Beta-glucans: Oats, barley, mushrooms. Whole grains (including... grains like barley and oats) support gut health and stable glucose release. Chickpeas: Combine with grains like barley or oats for amino acid complementarity.

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

Magnesium

Enzymatic cofactor (>300 reactions); neurotransmitters; mitochondria; redox balance

Propionate

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

Preparation Notes

• Soak before cooking to reduce phytates and improve mineral bioavailability
• Part of whole grain diversity strategy
• Supports gut microbiome via beta-glucans; beta-glucans support Bifidobacterium, Akkermansia; ↑ butyrate production; improved gut barrier
• Pair with legumes for complete amino acid profile; combine with legumes like chickpeas for amino acid complementarity

Biological Target Matrix

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
Metabolic & Neuroendocrine Stress (HPA Axis & ANS)	Magnesium	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Helps manage stress responses; combined with vitamin D reduced behavioral problems; synergy with zinc and omega-3s reported
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
Mitochondrial Function & Bioenergetics	Magnesium	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports enzymes involved in glycolysis and the Krebs cycle (processes that generate ATP from glucose); binds to ATP and all triphosphates in cells to activate them
Neurotransmitter Regulation	Magnesium	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Broad cofactor for neurotransmitter synthesis and receptor modulation (e.g., NMDA, GABA); functions as an NMDA receptor antagonist and GABA receptor modulator; assists enzymes involved in synthesis of dopamine and serotonin
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
