Flavonoid rich chocolate helps reduce ME symptoms

Saturday, December 30th, 2006

Eating small amounts of dark chocolate every day can help combat ME.
The specially-formulated chocolate helps reduce the symptoms of myalgic encephalomyelitis (ME), a study by researchers at England’s Hull and East Yorkshire Hospitals NHS Trust found.
People who took part in the study reported feeling significantly less fatigue after eating 1.5oz (45g) of the chocolate every [...]

Flavonoid Function

Tuesday, December 12th, 2006

Most flavonoids function in the human body as antioxidants. In this capacity, they help neutralize overly reactive oxygen-containing molecules and prevent these overly reactive molecules from damaging parts of cells. Particularly in oriental medicine, plant flavonoids have been used for centuries in conjunction with their antioxidant, protective properties. Scultellaria root, cornus fruit, licorice, and green [...]

Phytochemicals and Cardiovascular Disease

Tuesday, December 12th, 2006

Phytochemicals are chemicals found in plants. Plant sterols, flavonoids (FLAV’oh-noidz), and sulfur-containing compounds are three classes of micronutrients found in fruits and vegetables. These compounds may be important in reducing the risk of atherosclerosis (ath”er-o-skleh-RO’sis), which is the buildup of fatty deposits in artery walls. Within these categories are many possible compounds, most of which [...]

Antioxidant Activities of Flavonoids

Tuesday, December 12th, 2006

“Flavonoids are compounds found in fruits, vegetables, and certain beverages that have diverse beneficial biochemical and antioxidant effects. Their dietary intake is quite high compared to other dietary antioxidants like vitamins C and E. The antioxidant activity of flavonoids depends on their molecular structure, and structural characteristics of certain flavonoids found in hops and beer [...]

Biological effects of Flavonoids

Tuesday, December 12th, 2006

Flavonoids are widely distributed in plants fulfilling many functions including producing yellow or red/blue pigmentation in flowers and protection from attack by microbes and insects. The widespread distribution of flavonoids, their variety and their relatively low toxicity compared to other active plant compounds (for instance alkaloids) mean that many animals, including humans, ingest significant quantities [...]

Flavonoid Synthesis

Tuesday, December 12th, 2006

Flavonoids are synthesized by the phenylpropanoid pathway in which the amino acid phenylalanine is used to produce 4-coumaryl-CoA. This can be combined with malonyl-CoA to yield the true backbone of flavonoids, a group of compounds called chalcones. Ring-closure of these compounds results in the familiar form of flavonoids, a three-ringed structure (polyphenols). The metabolic pathway [...]
