I am not very knowledgeable on pregnancy-nutrition requirements, but the following may get you going with your removing-the-forms requirement:

use strict;
use warnings;
use WWW::Mechanize;
use HTML::TreeBuilder;

my $URL = q(http://home.comcast.net/~tankomail/preg.htm);

my $mech = WWW::Mechanize->new();
$mech->get( $URL );

my $tree = HTML::TreeBuilder->new();
$tree->parse( $mech->content() );

my @forms = $tree->find('form');
foreach my $form (@forms) {
    my $parent = $form->parent();
    $parent->push_content("BLOCKED");
    $form->delete();
}
print $tree->as_HTML();
$tree->delete();

__END__

You may need another tool to tidy up the html that this produces.
