heads up on cherimoyas--may be toxic, not a joke
A local grower told me that he heard that cherimoyas contain a toxic chemical called annonacin which can cause serious neurological damage, and a condition called "atypical Parkinsons" disease. Understandably, I was sceptical, but there are at least two articles on the subject published in very reputable scientific journals. The researchers have even identified the specific problem, which occurs in the mitochondrias of some nerve cells. This grower claimed to know someone who ate alot of cherimoyas and got very seriously ill, and apparently there is evidence that, in regions of the world where cherimoyas and other members of the Annona family (e.g. custard apple, guanabana, sugar apple) are grown, there is a signifant problem in those populations with dementia that can be traced to consumption of cherimoyas and similar fruits.
Just a heads up, folks. I doubt the California Cherimoya Association will be happy about this, but facts are facts. Before you go and eat alot of cherimoyas, I'd check this out for yourself.
