Nutrition & Diet

Microbiome reports can aid nutrition planning, but variable methods and incomplete validation mean they are best used as hypotheses, not prescriptions.

A practical, cautious look at seafood in a longevity diet: what helps, what does not, who should limit intake, and how much uncertainty remains.

A low-FODMAP plan can calm IBS symptoms when used briefly and deliberately, but evidence supports a phased, personal approach — not long-term strict avoidance.

Choline matters for liver, brain and cell health after 50, but evidence supports food-level adequacy, not high-dose capsules or egg evangelism.

Nuts can support a heart-healthier diet when they replace less useful snacks, but the evidence favours modest portions over miracle claims overall.

Magnesium-rich foods can help fill a common nutrition gap after 50, but the evidence supports a steady food pattern, not miracle claims or quick fixes.

Iron deficiency after 50 needs a better plate, not panic supplements. Here is what food can do, what absorption blocks, and when to see a clinician.

Cruciferous vegetables deserve their healthy reputation, but the evidence supports a practical food habit, not detox claims or longevity shortcuts.

Legumes look ordinary, but evidence links beans, lentils and chickpeas with better cardiometabolic health. The useful weekly dose is modest.

Prebiotics feed helpful gut bacteria, yet food sources still beat powders in the evidence. Onions, beans, oats, and chicory outperform most branded supplements.
