Greetings, Paula! While we have no rating for reindeer or tysk elk, I feel quite confident recommending them as "Neutral" for your type -- and I suspect this rating will apply to all members of the "Bambi" family you may encounter there in the Finnish woodlands! :-D

About wild duck, I am less sanguine. Duck, goose, grouse, partridge and quail are all avoids for Bs, which tells me that unlisted birdies are better considered "avoids" in your case. Pheasant, however, is fine for you, albeit rarer than ducks of all kinds, sorry to say!

Vaccinium vitis idaea (lingonberry) shares its small family Ericacea and genus Vaccinium with blueberries (including bilberries and whortleberries) and cranberries. My opinion is: eat them with gusto! Considering their relatives, they are likely Neutral for you, and might even be Beneficial.

Well, frankly, I had no idea rowan tree berries were edible at all... shame on me, and thank you for improving my education! I've always found the tree magnificently beautiful, and as it turns out, Sorbus aucuparia (European mountain ash, or "rowan") bears tasty fruit. You type Bs have much to be envied for, but for the moment I'll single out your magnificent fruit list. Rowan belongs to a huge family of plants (Rosaceae) of which not one is an avoid for you... so as to rowan berries, be my guest and call 'em "Neutral!" Hey - how do they taste? :->

Thanks for writing!!
