I hate to bring race and racism into this, but one reason why I laugh at many racists, especially European racists, is how they claim they love their own national culture but do jack shit to have ANYTHING to do with its pre-colonial cuisine. Take British cuisine for example. While obviously people in medieval England (even the richest people at the time) had far fewer options than most people in the UK today, but they still used many herbs and plants for seasonings that are only being rediscovered by reenactors in recent years, and they are actually quite good.

More than just culture, the dangers of over-reliance on a handful of crops and cultivars is also dangerous. The Irish potato famine happened in the 1840s due to Irish potato crops just being a few kinds instead of the hundreds of varieties that you would find in South America. The result of this is that a blight that would have had a negligible effect in South America absolutely devastated Ireland. More recently in the 20th century, we have a near complete destruction of the Gros Michel banana in the 1950s. When you go to your typical supermarket, the bananas you see there are more than likely going to be Cavendish Bananas, which were considered inferior to Gros Michel in the past, but due to disease rendering Gros Michel bananas commercially nonviable they were chosen because they were all we got...

and the same shit could happen at any time to the Cavendish banana, too.
