Can somebody elaborate on the nutritional / health differences between the two, if any?

If Shandong better? If yes, why? What are these called in English?

Yes I know menglembu is better. Shandong is bigger and a bit softer.

I'm just wondering if that's it, or there are health/nutritional benefits to eating the Shandong one.

Funny enough I always hated Shandong but recently eaten it and it's not as bad (or just a sign of growing up).

I say walnut too.
