Once you get a kiln and smelter you can make a cauldron out of tin. Plant carrot seeds and make carrot soup. Or you can use blueberries and raspberries to make queen's jam. Stamina foods are usually more plant based and health foods are usually meat based. Don't forget to upgrade the cauldron when you get turnips in the swamp.

Also Valheim Plus will let you tweak stamina. Get the newer "fixed" version of it.
