Canned olives are delicious, but not all that healthy.
Olives have a great reputation and it is well-deserved. However, there is a little problem: only fresh olives are actually healthy, but they are not edible. You can only eat them after they have been processed. When olives are preserved, there is too much salt used, so it is not very likely that they are still good for your health.
Olives are valued for a high concentration of fatty acids. Alternative sources of these elements are pumpkin and sunflower seeds. Besides, the seeds contain a lot of vitamin E.
