| About Artichoke [A] The artichoke was first developed in Sicily and was known to both the Greek and the Romans. In 77 AD the Roman naturalist Pliny called the choke one of earth's monstrosities, but many continued to eat them. Historical accounts show that wealthy Romans enjoyed artichokes prepared in honey and vinegar, seasoned with cumin, so that this treat would be available year round. It was not until the early twentieth cntury that artichokes were grown in the United States. All artichokes commercially grown in the United States are grown in California and Castroville, California, claims to be the "Artichoke Capital of the World." California even has an Artichoke Queen-the most famous queen was Marilyn Monroe in 1947. She inspired more people to eat artichokes in that year reign than any year before or after. Artichokes are actually a flower bud-if allowed to flower, blossoms measure up to seven inches in diameter and are a violet-blue color. Artichokes are a close relative to the thistle. High quality artichokes are usually compact and heavy for their size. Squeezed, a fresh artichoke will make a squeak. The thickness of each stalk should correspond to the size of the artichoke. Thin stalks signal dehydration, so look for stalks that are firm without 'give". storage Artichokes remain fairly constant in appearance for weeks, but flavor is adversely affected from the moment they are cut from the stalk. For maximum taste and tenderness, cook as soon as possible. Do not stock up on artichokes. Refrigerate unwashed, in a plastic bag, for up to 1 week. Preparation Artichokes should be washed under cold running water. Pull off the lower petals and cut the stems to one inch or less. Cut the top quarter of each artichoke and snip off the sharp tips. Artichokes turn brown very quickly once they are cut. To preserve the green color, one may dip in lemon water. Artichokes can be boiled, steamed, mocrowaved or sauteed. They can be eaten whole or added to other dishes. Micowave: cook 6-8 minutes or until a petal near the center pulls out easily. Boiling: Stand artichokes in a large pan with 3 quarts boiling water. Cover and boil gently 20-40 minutes according to size, or until the petal near the center pulls out easily. Small artichokes are good for pickling, stews, casseroles; medium size are good for salads and large size are good for stuffing. What does artichoke contain? One serving size of artichoke is 56 g edible portion. One serving of artichoke contains 25 calories, 0 g of fat, 0 mg of cholesterol, 70 mg of sodium, 3 g of dietary fiber, 16 g of sugars, and 2 g of protein. It is also a source of calcium, iron and vitamins A, C. [A] Artichoke leaves was found to contain anti-hyperlipidemic sesquiterpenes and sesquiterpene glycosides..cynarin, 1,3 dicaffeoylquinic acid, 3-caffeoylquinic acid, and scolymoside [1, 10]. These phenolic compounds are reported to have antimicrobial activties. [11] Artichoke flowers contain a Milk-Clotting Aspartic Proteinase. A study of proteinase expression in crude extracts from different organs of the globe artichoke (Cynara scolymus L.) disclosed that enzymes with proteolytic and milk-clotting activity are mainly located in mature flowers. Maximum proteolytic activity is at pH 5.0, and only pepstatin presents a significant inhibitory effect. Such properties suggest that this crude protease extract is potentially useful for cheese production. [8] What are the benefits of artichoke? Researcher also discovered its bile stimulating action and ability to reduce nausea, abdominal pain, constipation and flatulence (related to non-specific digestive disorders) [2,3]. This finding led to the popular use of its extract to treat mild indigestion in Europe. Artichoke pomace is a promising source of phenolic compounds that might be recovered and used as natural antioxidants or functional food ingredients. [14] A study has shown the possible benefits of artichoke on high cholesterol and triglycerides [4]. Artichoke juice has been shown to improve endothelial function in hyperlipemia. [9] Its lipid lowering effects may be related to the inhibition of cholesterol synthesis and/or its bile stimulating action (i.e. elimination of cholesterol) [5]. In a vitro study, its flavonoids have been shown to prevent LDL-cholesterol oxidation [6]. However, a clinical study has failed to find any related benefits [7]. Artichoke leaf extract has been to shown to reduce symptoms of irritable bowel syndrome. [12] Gebhardt R. found that the extracts of artichoke (Cynara scolymus) leaves might be able to prevent taurolithocholate-induced hepatic bile canalicular distortions [18] In addition, a study has demonstrated that an artichoke leaf extract induced Choleretic activity and biliary elimination of lipids and bile acids in rats [17] Other research studies showed that it may have benefits possibly on functional dyspepsia [15], irritable bowel syndrome, atherosclerosis and endothelial dysfunction [13]. Artichole Side Effects Ingestion of artichoke may cause acute enlargement (edema) of tongue. [16] THIS ARTICLE IS FOR YOUR INFORMATION ONLY.

| Artichoke is found in South Europe, North Africa, and the Canary Islands. Ancient Greeks and Romans used artichoke as a digestive aid. It may have health benefits on high cholesterol and indigestion. |
| The Jerusalem artichoke isn't in the artichoke family, but is a member of the sunflower family. Its official name is actually sunchoke. [A] |
