"What can they be? They have a semisoft texture, kinda firm but jellyish"

I agree with dairy - I quit dairy almost 2 years ago. One of the best things I've done too. I avoided fats, back when fats were evil. That did some bad things for my health. Now I eat extra fats on purpose - fats are soooooo important for health - digestion, brain function, absorbtion of ADEK vitamins, etc... What I am trying to say is... you might want to eat more good fat/oils and more protein :)
