What is extra-virgin olive oil?
Extra-virgin olive oil is the precious unrefined first result of cold-pressing olives to make a fruity liquid that contains less than one percent acid.
Extra-virgin olive oil is the most expensive olive oil variety, and it is best appreciated in salads or as a garnish to give preparations a final flourish. If you are using olive oil to cook, it's fine to use regular olive oil.
Greece is the #1 consumer of olive oil in the world and also the leading producer of extra virgin olive oils, which account for 82 percent of their olive oil production. The U.S. is not a member of the International Olive Oil Council (IOOC), which regulates olive oil standards worldwide, and the IOOC does not recognize the U.S. standards for extra-virgin oil.
There is much controversy in the olive oil world, with accusations of corruption and adulteration smearing consumer confidence and shedding doubt on the purity of so-called virgin olive oil.
What is the Doctrine of Signatures?
What is the Doctrine of Signatures?
The Doctrine of Signatures is a philosophy about plants that can be traced back to Medieval European alchemists, who believed that God gave plants a signature that hinted at its uses. Meaning, plants that resembled human body parts could be read as indicators of how those plants could be used to treat the body.
Popularized in the early 1600s by a German shoemaker who had mystical visions and wrote a philosophy book about the interconnectedness of nature and man, the Doctrine of Signatures was adapted by herbalists. They believed that because the leaves of a plant may have resembled a liver, say, they could be used to treat a bad one, or that an infusion of spotted leaves could help cure a diseased lung.
The Greeks prescribed brain-like walnuts to treat mental illness.
what you should know
Eons before humans knew what Omega-3 fatty acids were, our species was hip to walnuts.
food of the gods Fossilized walnuts dating from Neolithic times have been found, and written references stretch back into B.C. The botanical name for walnuts, juglans, is derived from the belief that the ancient Roman god Jupiter lived off of them. Depending on where you are in the world, walnut consumption has long been linked with a healthy heart, healthy bones, longevity, fertility, intelligence and libido.
nut cases Modern science continues to show that the walnut is one of the healthiest foods we can eat. Still, it's too often relegated to dessert. Try working walnuts into your diet by putting them in salads, spreads, soups and sandwiches. (Or sprinkling them with sugared bacon, a food for which modern science has shown little regard.)
break out of the shell Nut crackers abound, but buying shelled walnuts makes cooking with them much easier. Because walnuts are so fatty, they can spoil without the right care. If buying in bulk, stay away from shriveled or rubbery walnuts. Smell them to make sure they smell nutty and not rancid.
keep it cool At home, store walnuts in an airtight container in a cool, dry place. If you're going to have them for a while, put them in the fridge.
