Actually, Huge Samoans is largely a western phenomenon, After visiting Fiji, Solomon Islands, Samoa, Tonga and Vanuatu I have found that the average pacific islander is slightly smaller than the average white person. On one trip I was given a fairly decent explanation from a local young guy. After they leave the islands and go to large western populations, they eat tons of milk, eggs and dairy (which is in relatively small supply locally). These items are generally more expensive items on the islands, but in a city they can often be very cheap, at least comparatively.
