Your labs, gently informing what's on the plate.

ApoB

Strong cardio-metabolic signal. If elevated, down-rank saturated-fat-heavy meals, butter-forward recipes, coconut oil, fatty processed meats and ultra-processed foods. Prefer soluble fiber, beans, lentils, oats, olive oil, nuts, seeds, fish, lean proteins, and Mediterranean-style meals.

LDL-C

Similar to ApoB, with ApoB treated as the stronger signal when both exist. High LDL-C pushes toward higher-fiber, lower saturated-fat recipes.

HDL-C

Low HDL-C can support more activity, protein and fiber, but it's never chased alone — interpreted with triglycerides, ApoB, glucose, insulin and lifestyle.

Triglycerides

If elevated, reduce sugary sauces, refined carbs, desserts, alcohol-heavy pairings and high-glycemic meals. Prefer protein-forward, fiber-rich meals with slower carbs.

TG / HDL ratio

Useful metabolic signal. Higher ratio pushes toward lower glycemic load, fewer refined carbs, higher protein, more fiber, and post-meal walking suggestions.

LDL-C / ApoB ratio

Helps infer particle pattern. Used cautiously — never optimize toward 'low calorie but refined' meals.

Fasting glucose

If elevated, reduce high-glycemic recipes and sugary drinks. Prefer protein, fiber, vinegar / acidic dressings, slower carbs and balanced plates.

HbA1c

Longer-term glycemic signal. If elevated, prioritize lower-glycemic meal templates, carb quality, fiber, protein, and consistent meal timing.

Fasting insulin

Key early metabolic signal. If elevated, reduce refined carbs and snacking, increase protein and fiber, and prefer satiating meals.

Fructosamine

Shorter-term glycemic signal than HbA1c. If elevated, push lower glycemic load and protein / fiber pairing with carbs.

Uric acid

If high, limit beer / alcohol, sugary drinks and very high-purine foods like organ meats and some seafood. Never auto-bans all meat.

hs-CRP

If elevated, favor anti-inflammatory meals: colorful plants, omega-3 fish, olive oil, nuts, herbs / spices, fermented foods if tolerated. Down-rank ultra-processed and high-sugar meals.

Vitamin D (25-OH)

If low, prefer fatty fish, eggs, fortified foods and (where relevant) mushrooms. Adds a sunlight / lifestyle reminder. Never doses supplements without clinician input.

Vitamin B12

If low or borderline, prefer B12-rich foods like fish, eggs, dairy if tolerated, meat, or fortified foods for plant-based users. Pairs with methylation and homocysteine context.

Folate / RBC folate

If low, prefer folate-rich foods: leafy greens, legumes, asparagus, avocado, citrus, beets. Used alongside homocysteine, B12 and methylation markers.

Homocysteine

One of the most useful methylation-adjacent markers. If elevated, favor folate, B12, B6, choline and betaine-supportive foods, plus a clinician-review prompt. Never overreact to MTHFR without homocysteine.

Ferritin

If low, prefer iron-rich foods with vitamin C pairings, plus B12 / folate context. If high, do not blindly push red meat — consider inflammation / liver context and clinician review.

Iron / TIBC / Transferrin saturation

Distinguishes low iron availability from high iron load. Critical context before recommending more red meat or iron-heavy foods.

Magnesium / RBC magnesium

If low, prefer pumpkin seeds, nuts, legumes, leafy greens, cacao and whole grains if tolerated.

TSH

Thyroid screening. If abnormal, avoid extreme calorie restriction; favor protein adequacy, iodine / selenium awareness, and clinician review.

Free T3

Energy / metabolic context. Low Free T3 makes the assistant cautious about aggressive dieting or chronic under-eating.

Free T4

Completes thyroid context with TSH and Free T3 — used for confidence, never for medical claims.

Total testosterone

Drives protein adequacy, strength-training support meals, and zinc / selenium / healthy fat coverage. Never makes hormone-treatment claims.

Free testosterone

Interpreted with SHBG, age, sex and symptoms.

Estradiol

Used carefully by sex / age / cycle context. Can influence meal timing, fiber, alcohol moderation and hormone-supportive nutrition.

Progesterone

Cycle-phase aware. Never makes strong claims; can influence cravings, magnesium-rich foods and stable blood sugar meals.

SHBG

Helps interpret sex hormone patterns and metabolic context.

Hemoglobin

Low values raise priority for protein, iron-rich foods, B12 / folate context and clinician review.

Hematocrit

Used with hemoglobin, hydration and iron markers. Not over-interpreted alone.

Albumin

General nutrition / protein status. Low albumin triggers caution and clinician review rather than 'eat more protein.'

Creatinine

Kidney / muscle / hydration context. Used with eGFR before recommending high-protein meal plans.

eGFR

If reduced, avoids aggressive protein, potassium, phosphorus or sodium recommendations without clinician oversight.

GGT

Liver / oxidative stress / alcohol signal. If elevated, down-rank alcohol, fried foods, high-sugar meals and ultra-processed foods.

ALP

Liver / bile / bone context. Used with AST, ALT, GGT, bilirubin and vitamin D — never alone.

AST

Liver / muscle context. If elevated alongside ALT / GGT, down-rank alcohol and ultra-processed / high-sugar meals.

ALT

Liver fat / metabolic context. If elevated, prefer weight-loss-friendly, high-fiber, lower-sugar, higher-protein meals.

Sodium

If abnormal — or BP / kidney context — adjust salt-heavy processed foods, broths, sauces and cured meats.

Potassium

If kidney function is normal and potassium is low, favor potassium-rich whole foods. If kidney function is reduced or potassium is high, high-potassium guidance needs clinician review.

Non-HDL-C

Supports lipid scoring alongside ApoB and LDL-C.

Total cholesterol

Supporting lipid context only.

ApoA1

Lipoprotein balance context. Supporting cardio signal.

ApoB / ApoA1 ratio

Cardio risk pattern signal.

Lp(a)

Genetic-like cardio risk. Diet has limited effect; used to intensify heart-healthy defaults, never to promise lowering Lp(a) with food.

LDL-P / Small LDL-P / LDL size

Particle pattern. High small LDL-P pushes toward lower refined carbs and higher fiber.

HDL-P / HDL size

Supporting lipid context. Never optimized for in isolation.

VLDL-C / Remnant cholesterol

Triglyceride / remnant signal. Down-rank sugary or alcohol-heavy meals.

C-Peptide

Insulin secretion context. Supports lower glycemic load and higher-satiety meals when high.

HOMA-IR

Insulin resistance signal. Strong driver of lower glycemic load, higher protein and fiber, and fewer snacky recipes.

1,5-Anhydroglucitol

Optional post-meal glucose-spike marker. Tunes spike-sensitive recipes.

ESR

General inflammation context, used alongside hs-CRP.

ANA / RF / Anti-CCP

Autoimmune screening context. Never auto-generates restrictive autoimmune diets — flags clinician review.

IgA / IgG / IgM / IgE

Immune / allergy context. IgE may support allergy review, but food bans only come from confirmed allergy, user history, or clinician input.

MMA (methylmalonic acid)

Functional B12 marker. Strengthens B12-pathway recommendations.

Omega-3 Index / Omega 6:3 ratio

Drives fatty fish, seafood, flax / chia / walnuts, olive oil, and moderation of seed-oil-heavy processed foods.

Zinc / Copper / Selenium

Mineral adequacy. Drives nuts, seeds, legumes, seafood, eggs and Brazil nuts where appropriate.

Vitamin A / E / B6 (PLP) / Iodine

Micronutrient-aware suggestions. Used cautiously — especially iodine and fat-soluble vitamins.

Reverse T3

Optional stress / energy context. Soft signal only.

TPO / Tg antibodies

Autoimmune thyroid context. Never auto-bans gluten or dairy without diagnosis, symptoms, or clinician direction.

DHEA-S / AM cortisol / Cortisol:DHEA-S

Stress / recovery context. Influences caffeine timing, stable blood sugar meals, breakfast protein and sleep-supportive meals.

LH / FSH / AMH / Prolactin

Fertility / endocrine context. Used for summaries and clinician-review prompts only — never as recipe hard rules.

IGF-1

Protein / energy / metabolic context. Never over-interpreted in isolation.

WBC + differential

Immune / inflammation / allergy context. Eosinophils may support allergy investigation but never auto-ban foods.

RBC / MCV / MCH / MCHC / RDW

Pattern-matches possible B12, folate or iron issues; influences nutrient-prioritized meals.

Platelets / MPV

Inflammation / clotting context. Useful for risk-aware summaries, not stand-alone diet rules.

NLR / PLR / LMR / SII

Optional calculated immune-balance scores. Soft context only.

BUN / BUN:Creatinine

Protein / hydration context. Tunes protein intensity and hydration prompts.

Cystatin C

Refined kidney function marker — strengthens kidney-safe meal guidance.

Chloride / CO2 / Bicarbonate

Electrolyte and acid-base context.

Calcium / Phosphorus

Mineral balance for kidney, bone, vitamin D and electrolyte-sensitive meal planning.

Globulin / A:G ratio / Total protein

Protein / nutrition / liver / inflammation context.

Total + Direct bilirubin

Liver / bile context. Used alongside ALT / AST / GGT / ALP.

LDH

General tissue turnover. Soft supporting signal.

Mercury

If high, down-rank high-mercury fish and prefer low-mercury seafood.

Lead

Clinician-review flag. Supports calcium / iron / vitamin C adequacy — never implies food 'detoxes' lead.

Arsenic

Rice / seafood / water context. If high, diversify grains away from frequent rice-heavy meals.

Cadmium

Clinician-review flag. No detox claims.

Urine albumin / creatinine ratio

Kidney / metabolic risk. If abnormal, recipe engine avoids aggressive protein, sodium, potassium or phosphorus suggestions without clinician guidance.

Urinalysis / microalbumin

Supporting kidney signal.

Ketones

Diet context — useful when the user is intentionally low-carb or keto.

Urine pH / specific gravity

Hydration / kidney stone context. Soft signal only.
