spot on, you are what you eat. my favorite ff medium recipe (not my recipe actually, but my favorite one to use) is
1 cup banana (about 2 bananas)
1 cup apple sauce
1/8 cup vinegar (or 2 tablespoons or 15 ml)
2 cups oatmeal
Put the banana and apple sauce in blender or bowl and mix until the banana
is liquefied. Heat in the microwave for approximately 2 min. or until hot
enough to kill off any wild fruit fly eggs that were in the bananas, and to
reduce mold. Add the vinegar and mix in oatmeal until it becomes firm, but
still moist. I then put the mixture into a large freezer bag and keep it in
When it's time to make a culture, I scoop what I need and put it in the
culture container (usually microwaving it a bit to warm it up). I then sprinkle
a few pinches of bakers yeast on top.
of course you can add whatever vit/min supplements (e.g., chlorella) you like to make it even more nutritious. I never understood the reason for adding yeast, although everyone seems to do it. someone told me that the adult FF eat it, but that seems hard to believe. i also read that it inhibits the growth of less desirable fungi.
