What are flavonoids?
Flavonoids form a large family of vegetable matters. They had to colour in vegetables and fruit the large variation in, of yellow to red and dark purple. Flavones (Latin flavus = yellow) got their name at plant matter that uses became for the yellow paints of wool and cotton. They are indicated also as a bioflavonoid and former as a vitamin P.
Until now there are 4000 kinds of flavonoids described. They can become distinguish on the basis of theirs chemical structure in: Flavons, Flavonols, Catechins, Isoflavons, Flavonons and Anthocyans. 
Related bioactive matters are among many carotenes, glucosinoloids, organosulfids and terpenoids. The consumption of flavonoids in the western diet is compared with Asian countries at the low side, also because of the consequence of boil and work the content at flavonoids with 50 until 90 per cent goes down. Hence the advice is given to eat more (fresh) vegetables and fruit. There exists however no standard for the minimal quantity flavonoids that our diet should contain. |
Back to the top of this documentIn which foods come flavonoids and bioactieve matters for?
Lavonen: season
Isoflavons: soy, legume fruits Flavonols: onions, tea, apples, red wine, broccoli, farmer cabbage Catechins: tea, red wine and fruit Anthocyans: berries (juice), red wine, blue grapes Carotenes: yellow green vegetables, are rooted, tomatoes, oranges (for Beta-carotene click here) Glucosinolaten: sprouts, cabbage kinds, broccoli Organosulfiden: garlic |
What is the function of this kind of bioactive matters?
To that is done the last years many studies, but is known long not everything. Of a number flavonoids is known that they have, just as the vitamins A, C and E, an anti-oxidative function: they neutralize the harmful effect of aggressive oxygen molecules (going out oxygen radical or oxidants) on the cells. The in many studies fixed protective property of vegetables and fruit against cancer and heart and vascular diseases has possible to make with among many this activity of flavonoids and some other bioactive matters, as the carotene.
Further they can work in on enzyme and hormone systems and the defence system. They can influence play enzyme processes in favourable sense that a role by the cell division (cancer), the blood cluttering (dishes problems), the cholesterol levels (heart and vascular diseases) and the bodies defence (cancer). These effects were demonstrated with laboratory animals. Isoflavonen are indicated also as a plant hormones or phyto-estrogens. They resemble concerned what their chemical structure the human hormones. The most important divisions of phyto-estrogens are the isoflavons, the lignans and the coumestans. The western population gets via the feeding little phyto-estrogens, less then 1 milligram per day. In Asian countries, where much soy is eaten, lies the intake on 50 until 100 milligram per day. There are scientific indications that phyto-estrogens have a favourable influence on the prevention of breast, intestine and prostate cancer, heart and vascular diseases and osteoporosis. Phyto-estrogens commit at cells that be foresee of 'construction scaffolding' that fit by their chemical structure (oestrogen receptors). |
Can you take food supplements with isoflavonen without danger?
The accepted quantities of the most products that now are on the market, yield not finished of what the average person from Asia via its daily portion soy gets (50 until 100 milligram). Of that are no negative effects known. On the contrary, in the Asian countries much less breast, intestine comes and prostate cancer for then in the western world.
Scientists suspect that it a connection exists with the soy use. In general earns the recommendation (unless a physician otherwise prescribes) by use from. Food supplements with isoflavons no quantity to use that comes out above the 100 milligram. From studies namely not known what is can have this for consequences. Instead of food supplements also can be chosen for use of soy products. That are however sore protein realm through which the really all high protein consumption in our western feeding Yet further rises, unless they serve to replacement of other protein sources, as meat. In food supplements sit alone the bioactive matters from soy and are the proteins omitted. For more information over isoflavons see the website: http://www.isoflavones.info Sponsored Links |
