France consumes around 40-60 thousand tons of escargots per year. However, it does not appear that all these snails are helping with memories. France and Italy are and have been for many years the top countries with dementia. Could be also the effect of wine and cheese. Blessed with the large pool of escargot eaters, France is in a unique position to conduct further memory and snail studies.https://www.pssru.ac.uk/pub/dp2418.pdf
