Rice is for peasants. There’s a reason the Mongols beat the Chinese civilization. Fresh beef actually has a surprising amount of iodine. A few clams or sardines a week will cover it as well. Most nutritional deficiencies in history were from people eating plants and not meat. The ONLY sea vegetable I suggest to EVER eat as a chef, geographer and avid fisherman who knows how polluted the oceans are and Asian sourcing really works, should come from Maine. There’s a specific brand that should be easy to find online. Plus it supports American fisherman and sustaining some of the best ocean America controls. A lot of nori sheets used in sushi comes from polluted water which may even be radioactive. But no matter how much idodine you ingest, fluoridated water will hijack you anyways.

Cabbage... Found the Russian.

Ferment the cabbage first. Fermented cabbage is gtg.

Brassicas literally are bad for your thyroid. Look it up. Brassicas and almonds literally poison your thyroid. Not making this up.

It’s not healthy. More like it’s not that unhealthy. If you look at nutritional density by the numbers in actual data tables of all foods….red meat is almost all you need. Eggs. Shellfish or small oily fish. Plants are nothing compared to animals foods. Like nothing. Most humans that ever lived in time never ate cabbage and were far healthier and fit specimens. There’s a reason Northern Europeans and Central Asians average heights and IQs are larger than most of the planet. Agriculture came much later to them. All that crap we hear is mostly marketing and propaganda. Throughout most of history urbanized people could not reliably get meat into cities until the last hundred years so people became riddled with disease living shorter biological lives living off plants.
