Salads, pizzas, sauces and condiments, here are all the dishes that can be made even healthier thanks to a handful of pickled capers! In fact, as evidenced by a recent scientific research published in the Communication Biology Journal by a team from the University of California, Irvine School of Medicine, pickled capers contain a particular substance, quercetin, which activates a protein necessary for the proper functioning of the brain and the heart.
Pickled capers are a very tasty food spread all over the world today. But pickling does not only help to preserve capers and give them a touch of flavor. According to the research, in fact, it is precisely the pickling process that helps convert rutin, a substance of which capers are rich, in quercetin, a powerful antioxidant. Well, pickled capers represent one of the richest sources of quercetin. But why is quercetin so important? Because, as indicated by the authors of the study, quercetin modulates the potassium channels, namely channels that allow the passage of potassium ions through the cell membrane. A malfunction in these channels can cause several very common diseases, such as diabetes but also arrhythmia and epilepsy.
Thanks to previous research, we know that capers are anticancer and anti-inflammatory, today we also know that they act in a beneficial way for heart and brain health.
