I was considering the steroidal impact of certain foods on the human anatomy and wondered if any foods stimulate steroidal elevations in mollusc, this of course would cause increased growth and strength of internal organs, i am of course speaking of naturally occuring steroid boosters and not some artifical "cow growth hormones" so please do not head down to the nearest gym for a packet of naposim.
heres is what was found in a study;
Vertebrate-type steroids such as Progesterone (P4), Androstenedione (4AD), Testosterone (T), 17 β-Estradiol (E2), and Cortisol (F) occurred in significant amounts in the haemolymph of the female phase Achatina fulica. Interestingly, the male phase haemolymph had no E2 and 4AD was absent in both the male and the hermaphrodite phases. Ovotestis and albumen gland synthesized P4, 4AD, T, and E2 from endogenous precursors, the levels of which correlated well with those observed in the haemolymph. However, F is not synthesized by the reproductive tissues. The high concentration of F in the haemolymph clearly indicates the existence of a tissue system capable of synthesizing F. Identification of five vertebrate-type steroids in a mollusc is novel and has great significance.
it very interesting that in the male phase none of the typical male ( steroidal/growth) hormones are present especially 4AD.
I wonder if any of the long term knowledgable snail keepers here have looked into this As certain seeds have oils in them which are quite high in steroidal saponins.

I didn't know fulicas (and presumably all other snails as well) had gender phases. I wonder if manipulation of the diet could influence a snail to be in one phase or another. That would have a big influence on selective breeding techniques.

Hence my other question concerning fenugreek which has mild steroidal properties in humans and being quite high in protein ( im not sure of the full branch of amino acids as i havent checked ) a high good fat ratio, containing an excellent mix of vitamins and high in calcium.
I believe that if there are no adverse affects this seed could be a wonderful addition to our snails diets
What we really want to find out here is, can we help snails in captivity to grow bigger / stronger / healthier and be more likely to reproduce. This would be of a great benefit with awkward snails such as tigers.

i will be honest i'm not clued up on this but i agree if the seed has the propperties needed and no unwanted affects to the snail then it would be a definate benifit to the regular diet.
