About the expert
Focus: Practical nutrition, metabolic health, evidence translation
Why this matters
Practicing physician (Germany) and health educator working in a complementary-medicine setting, who translates research into practical, patient-friendly guidance. At his strongest he is unusually careful, separating laboratory from human evidence and steering people toward proven conventional treatment when it matters, as in his nail-fungus explainer. He runs a supplement shop and promotes his own books, so product-related suggestions carry a commercial interest, even where his general medical explanations are sound.

Selz: How oat preparation shapes the cholesterol and blood sugar benefit
Oats are among the most rigorously studied foods for cardiovascular and metabolic health, with an EFSA health claim for beta-glucan-driven cholesterol reduction at 3 grams daily. The episode walks through the mechanism (gel formation in the gut, bile-acid binding, LDL-receptor upregulation, short-chain fatty acid production) and pushes back on the recent online narrative that oats cause weight gain or are full of anti-nutrients. The practical message centers on form: steel-cut, rolled, oat bran, and overnight oats deliver the benefit more reliably than instant varieties.

Nail fungus: what actually works?
Nail fungus is a slow infection under the nail, and the damaged nail has to grow out over months, so even a working treatment doesn't make the nail look normal right away. First it is worth confirming it really is fungus, since trauma and other nail problems look similar. Prescription antifungal medicines work best, topical ones for milder cases and terbinafine tablets for stubborn ones; natural oils have limited evidence; and kitchen cures like vinegar or garlic lack good evidence that they work. For people with diabetes, it deserves extra attention.
