Eating healthy can be expensive and I am always looking for ways to extend the life of my fruits and vegetables naturally. Everyone knows avocados are a great source of heart healthy omega-3 fatty acids but the window for eating them is so small - and they are not cheap. Bananas give off ethylene gas which is a type of plant hormone that speeds up the ripening of bananas and any other fruits or veggies that are stored near them. So there it is, bananas and avocados really don't get along - keep them separated in the kitchen and you might just get a couple more days to make your guacamole for this long weekend coming up!
