Dishes with seafood are very popular recently. However in days of a post when it is impossible to eat everything that contains meat, eggs and dairy products, involuntarily you ask a question and whether it is possible to eat squids, shrimps and mussels if you adhere to fast food.
All know that in a post under a ban meat, eggs and all dairy products, however as for seafood - for many remains a riddle. For this reason the question of whether it is possible fasting in a post is shrimps, squids and mussels interests the considerable number of people.
So, all above-mentioned seafood belongs to family of Crustacea (shrimp), cephalopods (squids) and two-fold (mussel) mollusks, and they not plant origin for this reason it is impossible to eat them. And if you strictly adhere to a post, then exclude them from the diet.
You shouldn't forget that the post is not only refusal of a certain food, this achievement of the spiritual purposes, and it is almost impossible to reach them without special food. If for you it is difficult to refuse seafood, then use them as seldom as possible, for example, only on Sundays. According to church instructions to eat fish dishes and seafood it is authorized only in the Palm Sunday and for the Annunciation, caviar not under a ban on the Lazarus Saturday. I will remind that in 2017 the Lazarus Saturday - on April 8, Pussy-willow Revival - on April 9, and the Annunciation - April 7.
The Lent lasts long very much, the whole 48 days, and much just can't exclude completely animal products from the diet for such long term. Therefore that not ""break"", buy a little seafood and put them in the freezer. In days when you very much want to interrupt a post, just boil a few shrimps or squids and make from them salad. The similar dish won't be considered as strong derogation from a post.
