GO FOR YELLOW

You’ve no doubt heard that bananas are a rich source of potassium, and now US researchers are pinpointing exactly how the mineral is good for your heart. University of Alabama at Birmingham researchers have shown, for the first time, that mice with reduced potassium in their diet had elevated stiffness in the aorta, when compared with mice that were fed a normal amount of potassium. Such arterial stiffness in humans is predictive of heart disease – and death from heart disease. Time to peel, slice, blend, mash or freeze those potassium-rich bananas! Avocados are another good source of potassium, so if you’re not already a fan of smashed avo on toast for Sunday brunch, you might want to give it a try.
