Backward Glossary Phytochemicals Q!

Glossary Online Glossary edited with meticulous attitude and published as convenience for site content reference,including glossaries of related different topics,Glossary Phytochemicals are dedicated to Phytochemicals and phyto derived chemical components.Phytochemicals have been used as drugs for millennia. Hippocrates may have prescribed willow tree leaves to abate fever. Salicin, having anti-inflammatory and pain-relieving properties, was originally extracted from the white willow tree and later synthetically produced become the staple over-the-counter drug called Aspirin!

 Glossary Phytochemicals Icon01
 Phytochemicals are chemical compounds such as beta-carotene that occur naturally in plants. The term is generally used to refer to those chemicals that may affect health, but are not yet established as essential nutrients.While there is abundant scientific and government support for recommending diets rich in fruits and vegetables, there is only limited evidence that health benefits are due to specific phytochemicals.

 Glossary Phytochemicals Icon02
 There is evidence from laboratory studies that phytochemicals in fruits and vegetables may reduce the risk of cancer, possibly due to dietary fibers, polyphenol antioxidants and anti-inflammatory effects. Specific phytochemicals, such as fermentable dietary fibers, are allowed limited health claims by the US Food and Drug Administration (FDA).
