Fennel can: .
Fight free radicals . Fennel contains its ownunique combination of phytochemicals, including the flavonoidsrutin, quercitin, and various kaempferol glycosides…, that give itstrong antioxidant activity. In addition to its unusualphytochemicals, fennel bulb is an excellent source of vitamin C,you body's primary water-soluble antioxidant, which can neutralizefree radicals in all aqueous environments of your body. If leftunchecked, these free radicals cause damage to your cells that canresult in the pain and joint deterioration that occurs inconditions like osteoarthritis and rheumatoid arthritis. Manganesein fennel is a co-factor for the antioxidant enzyme, superoxidedismutase, which disarms free radicals produced within themitochondria (the energy production factories within your cells).Isorhamnetin in fennel leaves is a powerful antioxidant thatprotects your body's cells from damaging free radicals. .
Build strong bodies . The vitamin C in fennelbulb helps produce collagen, which builds strong bones, muscles,blood vessels, gums, mucous membranes, corneas, joints, and othersupporting cells and tissues, helps you absorb iron and calcium.Potassium in fennel regulates muscle contraction and nervetransmission, stores carbohydrates for muscles to use as fuel,promotes regular muscle growth, and maintains the density andstrength of bones by decreasing urinary calcium loss. Manganese infennel activates enzymes for using several key nutrients, andfacilitates protein and carbohydrate metabolism and formation ofbone. Folate in fennel acts as a co-factor for enzymes involved inthe synthesis of DNA, supports red blood cell production and helpsprevent anemia, supports cell production, especially in your skin,allows nerves to function properly, helps prevent neural tubedefects in fetuses, helps prevent osteoporosis-related bonefractures, and helps prevent dementias including Alzheimer'sdisease. Phosphorus in fennel helps in the formation of bones andteeth, helps you use carbohydrates and fats and synthesize protein,and helps with energy storage, muscle contraction, kidney function,and nerve conduction. Molybdenum helps in metabolizing fats andcarbohydrates, mobilizing iron from your liver, which can preventanemia, and preventing tooth decay. .
Fight chronic inflammation. The anethole in fennel can reduceinflammation and help prevent cancer, perhaps by shutting down anintercellular signaling system called tumor necrosis factor (orTNF)-mediated signaling. By shutting down this signaling process,the anethole in fennel prevents activation of a potentially stronggene-altering and inflammation-triggering molecule calledNF-kappaB. .
Fight infections . The vitamin C in fennel bulbis kills pathogens and promotes a healthy immune system. .
Promote cardiovascular health . As a very goodsource of fiber, fennel bulb may help to reduce elevatedcholesterol levels. In addition to its fiber, fennel is a very goodsource of folate, a B vitamin that converts a dangerous moleculecalled homocysteine into other, benign molecules. Homocysteine candirectly damage blood vessel walls, and high levels are considereda significant risk factor for heart attack or stroke. Fennel isalso a very good source of potassium, a mineral that regulatesheart rythym and lowers blood pressure by counteracting thedetrimental effects of sodium and regulating fluid balance.Isorhamnetin in fennel leaves is a powerful antioxidant that helpskeep your heart healthy by preventing arteriosclerosis (hardeningand loss of elasticity within the arteries), preventing high bloodpressure, and protecting your heart's cells against oxidativedamage. .
Prevent cancer . The vitamin C in fennel helpsprevent cancer by neutralizing volatile oxygen free radicalmolecules and preventing damage to your DNA that can lead to cancerand by destabilizing a tumor's ability to grow under oxygen-starvedconditions. Because fiber removes potentially carcinogenic toxinsfrom your colon, fennel bulb may also prevent colon cancer. Folatein fennel lowers your risk of cancer by preventing build-up ofhomocysteine in your blood. Isorhamnetin in fennel leaves is apowerful antioxidant that prevents multiple types of cancer(including esophageal cancer, liver cancer, and lung cancer). .
Eliminate toxins . The volatile oil of fennelcan protect your liver from toxic chemical injury. Molybdenum infennel helps in eliminating toxic substances. The quercetinderivatives isoquercetin and rutin in fennel increase intestinaland liver phase I detoxification enzymes. Caffeoylquinic acids infennel may also be responsible for its choleretic properities(increasing the volume bile and solids secreted from yourliver). ( Full Answer )
