Lecithin is usually from Soy so maybe look in the soy foods section … AND “salt substitute” (potassium iodide) is usually marketed as “low sodium salt” or “sodium free salt” for people who have problems with high sodium amounts. I’ve typically seen it large supermarkets right next to the normal salt… just in a different color container.
The online calculator is awesome for ‘normal’ whole food too. I’ve been on a mixed soylent/no soylent diet for a few weeks now. The experiment continues.
I’d like to revive the idea of having a soylent achievement wall at the space! Little tags/plaques. “Member survived on powder diet for a week. Unlocked the Bland Palate achievement”
