WikiBiomeThe human microbiome encyclopediaAn alphabetical index of analyses in the public WikiBiome knowledge base.
A synthesis of how dietary heavy metal exposure varies across the human lifespan, highlighting that the same metals present different risks at different developmental stages due to changing absorption rates, detoxification capacity, dietary patterns, and organ vulnerabi…
This page identifies the contradictions and clinical dilemmas that become visible only when the 236 source pages in this wiki are read together. Each paradox describes a situation where evidence-based dietary or supplementation advice -- advice that is correct for most …
This page synthesizes findings across 1,426 source pages to map the relationships between metals and disease. Where individual source pages document a single study's findings, this page identifies the patterns that emerge when those findings are laid side by side. ADVER…
An analysis of which microbial taxa appear across multiple disease signatures in this knowledge base, what metal dependencies they share, and what the taxonomic overlap reveals about shared pathogenic mechanisms. This analysis covers the 13 disease signatures currently …
Vitamin C (ascorbate) is broadly protective: it reduces nickel absorption from food (acting as a competitive inhibitor in the GI tract), is the most commonly recommended adjunct to low-nickel diets zirwas 2009 dietary nickel dermatitis, and is a critical cofactor for DN…
While Cr(III) deficiency may contribute to glucose intolerance, supplementation trials have produced inconsistent results. The disconnect between mechanistic plausibility and clinical trial evidence suggests that Cr supplementation may only benefit the subset of patient…
Copper is elevated in the blood/serum of nearly every disease state examined in this wiki: | Disease | Cu Direction | Evidence | |---|---|---| | PCOS | Elevated | SMD = 0.51, p < 0.0001 (meta-analysis of 9 studies) | | Breast cancer | Elevated | SMD 2.44 in plasma/serum…
Fish is the primary dietary source of methylmercury (MeHg) -- a potent neurotoxin that crosses the blood-brain barrier, depletes glutathione, and can increase amyloid-beta production and tau phosphorylation mercury. MeHg is 95-100% absorbed in the intestinal tract. An e…
Celiac patients achieve serological remission on a gluten-free diet (GFD), confirming that the diet is working at the immunological level. Yet a subset develops NEW or WORSENING gastrointestinal and extraintestinal symptoms on prolonged GFD. The cause: gluten-free subst…
Lei et al. (2018) demonstrated that hydrogen sulfide promotes endometrial stromal cell proliferation via NF-kB activation. CBS and CSE (H2S-producing enzymes) are overexpressed in ectopic endometrium. NF-kB is also activated by nickel exposure in allergic contact mucosi…
Iron deficiency is common and clinically significant across multiple conditions: postpartum anemia increases PPD risk 1.89-fold (RR = 1.887), low ferritin (<1 ug) increases PPD risk 3.98-fold azami 2019 anemia ppd meta analysis, iron deficiency impairs thyroid peroxidas…
Restricting dietary nickel has clear benefits for nickel-sensitive individuals: it resolves SNAS symptoms, improves Ni ACM, and even enhances H. pylori eradication. Campanale et al. (2014) found that adding a nickel-free diet to standard triple therapy increased H. pylo…
Anti-inflammatory and plant-forward diets are the standard nutritional recommendation for endometriosis, PCOS, rheumatoid arthritis, and IBD. These diets emphasize legumes, whole grains, nuts, seeds, dark chocolate, and cruciferous vegetables -- precisely the foods with…
Probiotics protect the gut barrier from heavy metal toxicity. Zhai et al. (2016) demonstrated that L. plantarum CCFM8610 protected intestinal epithelial cells from cadmium through a four-part mechanism: metal sequestration in the gut lumen, alleviation of oxidative stre…
Zinc deficiency is a consistent finding in breast cancer, and Zn plays key roles in immunity (T cell differentiation), p53 activation, and SOD cofactor function. Yet supplementation data are limited, and in the Sister Study, zinc showed a dose-related positive associati…
Zinc is depleted in nearly every disease state examined in this wiki -- cancer (breast, prostate, lung, pancreatic, esophageal, colorectal), type 2 diabetes, PCOS, autism, postpartum depression, and IBD. Zinc supplementation is generally beneficial: it reduces PPD risk …
Could counter Zn depletion, but excess Zn promotes A-beta aggregation in plaques doroszkiewicz 2023 common trace metals alzheimers parkinsons.
