Protein Powder and Acne: Why It Happens, Which Types Are Worst & What to Switch To
Whey protein is one of the most consistently reported acne triggers — for specific reasons. Here's the mechanism, which other gym factors matter, and what to switch to.
Vitamin B & Acne: Which B Vitamins Trigger Breakouts, Which Help & Why B12 Is Different

Gut Health & Acne: The Gut-Skin Axis, LPS Translocation & What Actually Helps
The gut-skin axis is real — intestinal permeability allows LPS from gut bacteria to trigger the same TLR4 inflammatory cascade driving acne. Here's what the evidence shows and what to do about it
Bananas & Eczema: Nutrients, Histamine Liberation & the Latex-Fruit Syndrome Explained
Bananas contain vitamin B6, resistant starch, and potassium that support eczema from the inside — but latex-fruit syndrome and histamine liberation create specific risks for a subset. Here's how to tell which applies to you
Hormonal Acne Diet: The IGF-1 Mechanism, Foods That Raise Androgens & What Actually Helps
High-glycaemic foods and dairy raise IGF-1 and activate mTORC1 — the same androgen-stimulating pathway driving hormonal acne. Here's what to eat, what to avoid, and why spearmint and DIM specifically address the hormonal dimension
Turmeric for Acne: The Curcumin NF-κB Mechanism, the Bioavailability Problem & What the Evidence Shows

Collagen & Psoriasis: The MMP Breakdown Mechanism, Type II for Psoriatic Arthritis & What the Evidence Shows
Psoriatic inflammation accelerates collagen breakdown through MMP-1 and MMP-3 enzymes. Type I collagen supports dermal repair; Type II is specifically relevant to psoriatic arthritis. Here's what the evidence shows for each.
