5. Olive oil
Olive oil when used with vegetables, flatbreads and salads has a great taste. Not only is it tasty but it’s also healthy and rich in anti-oxidants. According to several researchers incorporating olive oil in certain diets is known to reduce depression levels. If you’re particularly a big fan of the Mediterranean diet, you could try making an interesting stir fry using olive oil or you could try making a new salad dressing using it.
