diAmonds and gems seem redundent.
Also, there are balance issues with adding a billion individual fruits if you make them all grant happiness or health. And why the hate for Papaya and Mangos, eh? Or Kiwi. Grapefruit.. Oranges... It's a slippery slope.
Also where are your nuts? Other then the Haze-nut. Hazelnut. Winery for Currants but not for Pears or Apples? What about for Plums?
And where's the pickeling improvement? How about the drying hut for dried fruits? The smoke pit for smoked meats?
Hens? Why not chickens? And what about Ox?
I think it's MamMoths, btw... Pheasent and Rabbits? Don't you think these are all potentially covered by *Game*? 'cept for Camels.
Rather then Papyrus, you should go for Reeds.
The only serious addition I might point out would be Platinum (other then one's I think have already been suggested).
Really, though it's a question of where you draw the line, and what abstractions you want to use. Tropical Fruit, Citrus Fruits, Tree Fruits (apples, pears, etc.), Berries...
Anyway...
