Jerusalem artichokes are also known as sunroot, sunchoke, earth apple and topinambour, according to Wikipedia. They can be eaten by guinea pigs, but this should be considered a special, rare treat only. This is because they have high sugar, low vitamin C, and a not-so-great calcium-phosphorous ratio. So you'll only want to feed this one in small portions 1-2 times per month.
