Recipe nutrition
Figures are still calculated from USDA-based nutrient data on each food page (per 100 g). For this recipe we have not yet added ingredient weights, so the table adds one full “100 g” slice of each linked food, not the grams actually used (which would misrepresent small amounts like herbs, spices, or oil). When portion sizes are added for the recipe, the same panels are multiplied by the real amounts—so the maths can be precise for every ingredient.
Aggregate %RDA uses adult reference intakes and the summed food-level values shown above.
* Protein is shown as a range, benchmarked to 1.2 g/kg/day using a 50-100 kg reference adult range.
Biological Target Matrix
Gut–Brain Axis & Enteric Nervous System (ENS)
| Substance | Contribution Level | Foods | Mechanism of Action |
|---|---|---|---|
| Choline | Contextual / minor contributor | Choline is metabolised by gut bacteria; some strains (e.g. Lactobacillus) can produce acetylcholine. Microbial choline metabolism (e.g. trimethylamine) shows inter-individual variability and may influence host metabolism and gut–brain signalling. |
Inflammation & Oxidative Stress
| Substance | Contribution Level | Foods | Mechanism of Action |
|---|---|---|---|
| Choline | Contextual / minor contributor | Choline-derived betaine supports homocysteine remethylation; elevated homocysteine is linked to oxidative stress and inflammatory signalling. Phosphatidylcholine supports membrane integrity and cell signalling in immune and redox contexts. |
Metabolic & Neuroendocrine Stress (HPA Axis & ANS)
| Substance | Contribution Level | Foods | Mechanism of Action |
|---|---|---|---|
| Choline | Contextual / minor contributor | Choline supports hepatic VLDL assembly and lipid export; methyl donors (choline, betaine) may influence adenosine metabolism and HPA axis activity. Adequate choline status supports metabolic stability and stress physiology. | |
| Magnesium | Contextual / minor contributor | Helps manage stress responses; combined with vitamin D reduced behavioral problems; synergy with zinc and omega-3s reported | |
| Vitamin C (Ascorbate) | Contextual / minor contributor | Supports stress response through antioxidant and neurochemical effects |
Methylation & One-Carbon Metabolism
| Substance | Contribution Level | Foods | Mechanism of Action |
|---|---|---|---|
| Choline | Contextual / minor contributor | Precursor to trimethylglycine (TMG/betaine), a dietary methyl donor that helps recycle homocysteine to methionine via an alternative pathway; supports one-carbon metabolism alongside folate, riboflavin, and B12; influences methylation dynamics relevant to MTHFR and COMT activity | |
| Methionine | Contextual / minor contributor | Essential amino acid that forms S-adenosylmethionine (SAMe), the universal methyl donor for neurotransmitter synthesis and membrane phospholipid methylation | |
| Vitamin B2 (Riboflavin) | Contextual / minor contributor | FAD acts as a critical cofactor for MTHFR, linking riboflavin to homocysteine recycling and methylation capacity | |
| Vitamin B6 (Pyridoxine → PLP) | Contextual / minor contributor | Essential cofactor in remethylation of homocysteine to methionine, which is converted to S-adenosylmethionine (SAMe); works with B2, folate, and B12 | |
| Vitamin B9 (Folate; 5-MTHF) | Contextual / minor contributor | Essential cofactor in remethylation of homocysteine to methionine, which is converted to S-adenosylmethionine (SAMe); SAMe fuels synthesis of dopamine, norepinephrine, and serotonin and drives phospholipid methylation in neuronal membranes | |
| Zinc | Contextual / minor contributor | Deficiencies in vitamins and minerals essential for methylation, such as folate, vitamin B12, and zinc, are correlated to ADHD symptoms; supplementing these micronutrients has shown potential in supporting methylation and reducing symptom severity |
Mitochondrial Function & Bioenergetics
| Substance | Contribution Level | Foods | Mechanism of Action |
|---|---|---|---|
| Choline | Contextual / minor contributor | Phosphatidylcholine and other choline-containing phospholipids support mitochondrial membrane integrity and energy metabolism; choline-derived betaine contributes to one-carbon status that can influence mitochondrial resilience |
Neurotransmitter Regulation
| Substance | Contribution Level | Foods | Mechanism of Action |
|---|---|---|---|
| Choline | Contextual / minor contributor | Essential precursor for acetylcholine synthesis, supporting memory, learning, and neuroplasticity; supports membrane phospholipid biosynthesis (PC) which is critical for membrane fluidity and neurotransmitter receptor function; phospholipid methylation (PLM) alters membrane structure, facilitating faster neuronal recovery and influencing ion channel behavior in gamma oscillations linked to attention and cognition | |
| Copper | Contextual / minor contributor | Cofactor in dopamine β-hydroxylase, supporting catecholamine synthesis; supports norepinephrine synthesis | |
| Iron | Contextual / minor contributor | Essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to dopamine; critical for catecholamine synthesis | |
| Magnesium | Contextual / minor contributor | 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 | |
| Phenylalanine | Contextual / minor contributor | Essential amino acid that converts to tyrosine and supports catecholamine synthesis (dopamine, norepinephrine); participates in LAT1 competition at the blood-brain barrier | |
| Potassium | Contextual / minor contributor | Critical for membrane potential, nerve signaling, and neuronal excitability; adequate intake balances sodium effects | |
| Tryptophan | Contextual / minor contributor | Precursor for serotonin and melatonin; brain entry competes at LAT1 with other large neutral amino acids (LNAAs); carbohydrate-rich, low-protein meals raise the plasma tryptophan:LNAA ratio because insulin pushes competing LNAAs out to muscles; can feed NAD+ synthesis via the kynurenine pathway | |
| Vitamin B6 (Pyridoxine → PLP) | Contextual / minor contributor | Cofactor for synthesis of dopamine, serotonin, GABA, and glutamate; supports rate-limiting steps in catecholamine synthesis; requires PDXK activation with magnesium and ATP support | |
| Vitamin B9 (Folate; 5-MTHF) | Contextual / minor contributor | Supports neurotransmitter synthesis through methylation; cofactor for dopamine synthesis alongside iron, B6, and omega-3s | |
| Vitamin C (Ascorbate) | Contextual / minor contributor | Supports norepinephrine synthesis; transported in brain via SVCT2 | |
| Zinc | Contextual / minor contributor | Important for DNA synthesis, cell division, and neurotransmitter regulation, particularly in modulating dopamine—a key neurotransmitter implicated in ADHD; acts as an allosteric modulator of the GABA receptor; supports glutamate regulation |
