[Rails] preserving carriage returns

When I enter some text in a text_area with carriage returns and then
store the text in a database the carriage returns are preserved in the
db. When I get the string back the carriage returns are gone, replace by
spaces.
example.
if I enter :

blah
blah
blah

the db stores:

blah
blah
blah

when i show the record I get:

blah blah blah

I tried to split string by:

<% @day.food.split('\r\n').each do |line| %>
<%= line %><br/>
<%end%>

but it doesn't work. The \r\n is there. I put a <% p line %> in and
looked at the logs.
The string does not get split.

anyone help?
