Subject: 126'th update on fly longevity experiments
This is the 126'th update of my fly longevity experiments. Average
temperature was 21.3 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 125 days.
Here I retest white kidney beans, and take a look at another type of
banana called plantain.
White kidney beans at the 8% level have repeatedly extended maximum
survival in the past, and this run repeats this. The 4% level had no
effect, but the 12% level had one fly, that "by chance", lived almost
twice as long as any of the control flies. At 122 days, which is just 3
days short of the estimated maximal longevity of 125 days. No control fly
has ever lived this long, and only one pomegranate fed fly from run #87
lived even longer - 124 days.
Unlike desert banana, plantain increased maximum survival, which
suggests the active prolongevity ingrediant was both different, and more
stable. Leucocyanidin, which is the active anti-ulcer ingrediant in
plantain is known to be more effective than the anti-ulcer ingrediant(s)
in desert bananas. (Journal of Ethnopharmacology 65 1999; 283-288) Please
note that this experiment used raw plantain, while humans typically
consume plantain only after cooking, which destroys the leucocyanidin. I
had earlier obtained positive results with the Leucoselect brand of grape
anthocyanidins.
