Food, gut & metabolism
Fermented food, probiotics, the microbiome, family food, and supplements with a narrower use than the label suggests.
Current evidence
Fermented food, gut immunity, the Stanford diet trial and home-fermentation safety. What a jar of sauerkraut can do and which claims the studies do not support.
Microbe counts, gut immunity, serotonin, probiotics and food targets. The microbiome numbers that became too easy to repeat.
What EPA and DHA do, where prescription evidence applies, why Omega-3 Index targets are not universal, and how product, dose, meals, medicines, pregnancy, and age change the decision.
Sleep, movement, food and family routines for children aged 6 to 12. What the evidence supports without turning childhood into medical arithmetic.
