A July 2019 study by the University of Eastern Finland found rye contributes to good gut health. The study found, "The major role played by gut microbes in human health has become more and more evident over the past decades, and this is why gut microbes should be taken very good care of. It's a good idea to avoid unnecessary antibiotics and feed gut microbes with optimal food - such as rye,"

Our advice is to eat 100% rye bread rather than “rye bread” which has a proportion of wheat flour in it.
