This invited review on the beneficial effects of nutraceuticals in the gastrointestinal tract reports previous work conducted
by the authors as well as the work by other researchers in this expanding field. The text of our article on several occasions reports
sentences very similar or identical to those which appear in the manuscript from which the information was obtained and
this applies to both our own work and some other researchers’ work. This was mainly due to the fact that we tried to maintain
unchanged the original meaning of what we reported in our review. Also, it was our intention to give full credit to the authors
of manuscripts dealing with the gastrointestinal effects of nutraceuticals and in some instances we preferred to quote the original
paper rather than the review where this original information was taken from.
We realize that a number (8) of manuscripts, source of the information reported in our review, were not included in the reference
list (which contains over 100 references) and we deeply apologize for this with the authors of the missing references.
In most of the cases this was due to a mistake in the final editing of the manuscript. In some other cases this was because we
tried not to exceed the number of references requested.
We therefore, by means of this addendum, would like to add to the reference list taken out the articles which were not
quoted in the manuscript at the time it was published. Two of the articles deal with the effect of nutraceuticals in the upper gastrointestinal
tract. The remaining six deal with the effect of nutraceuticals in the lower gastrointestinal tract.
