the best thing for smoothies is bananas--freeze them!
(peel them before freezing) also some protein powder
or Spiruteina or yeast (not brewer's-it tastes too yucky)
try red star flaked food yeast--to make sure you are getting
good nutrition...and take vitamins. If you need B12 --put marmite
in your whizzed soup!!
also miso soup is quite nourishing....you can make it into a
broth. You should be able to find this in a health food store..
yogurt or acidophiolus has beneficial bacteria for you body...
