These results reveal that not all fermentable fibers are equally capable of stimulating SCFA production, and they highlight the importance of the composition of an individual’s microbiota in determining whether or not they respond to a specific dietary supplement. In particular, R. bromii or C. chartatabidum may be required for enhanced butyrate production in response to RS. Bifidobacteria, though proficient at degrading RS and inulin, may not contribute to the butyrogenic effect of those fermentable fibers in the short term.

In this article, we address the question of whether the policy statements of political parties with regard to migration affect the link between individual anti-immigrant sentiment and support for redistributive policies. While the effect of political parties “playing the race card” is well documented and repeatedly discussed in the American context, it has received little attention in comparative studies. We test our measurements of issue-salience with regard to migration and welfare-related matters by conducting multilevel models for a sample of 14 European countries. We also control for the potential effects of the countries’ welfare regimes—which is so far the most prominent contextual variable. Our results strongly indicate a moderating party-effect: The more parties accentuate crucial migration issues, the less general support there is for welfare programs by native anti-immigrant groups. In contrast, we find no effect of the repeatedly discussed welfare regime on this relationship, once controlled for party statements.
