antiossidanti,soprattutto per N.man...

[checco78]

..avrei trovato un prodotto potenzialmente interessante per contrastare l'effetto dei radicali liberi,supplementare una moderata dose di vitaminaC e anche del glutatione..il prodotto si chiama OCUCLAR,è venduto solo in farma ma HA delle INDICAZIONI ben precise,può cmq essere utile?

[NaturalMan]

è stato ideato per contrastare "l'invecchiamento del cristallino" ... cmq personalmente mi orienterei su altri prodotti dove magari troverei anche del buon ALA e altre piccoli preziosi microelementi.... se vuoi provalo!

Byeeeeeeeeeeeeeeeeeeeeeeeeee

esempio quale prodotto??

[NaturalMan]

Se fai un pò di ricerca trovi prodotti buoni (nn adoro fare pubblicità) .... personalmente il mio antiossidante ideale dovrebbe contenere almeno questi prodotti:

Coenzyme Q10
Luteina
ALA
Thè Verde
Licopene
Vitamina A-C-E
Zinco chelato AA
Selenio
Flavonoidi

questo potrebbe essere un buona idea di antiossidante ma solo nelle giuste grammature altrimenti gli effetti sono praticamente OSSIDANTI..... credo che svilupperò un prodotto simile a riguardo

Il dipartimento Americano dell'Agricoltura (USDA) ha messo appunto un test atto a misurare l'attività ossidante degli elementi (ORAC "oxigen radical absorbance capacity")o almeno a dare un valore indicativo del loro potere antiossidante, da questi test si deduce che:
------------------------------------------
ORAC - ALIMENTO (100 gr)
------------------------------------------

5770 prugne secche
2830 uva sultanina
2400 mirtilli
2036 more
1770 cavolo verde
1540 fragole
1260 spinaci crudi
1220 lamponi
908 cavolini di bruxell
890 broccoli
840 barbabietole
750 arancie
739 uva rossa
713 peperoni rossi
670 ciliegie
602 kiwi
-----------------------------------------

mentre la migliore bevanda in assoluto è risultata il thè verde...

cosa ne pensate...

ps-naturalman....tu ne sai di più....

...interessante.. avevo letto qualcosa a riguardo l'anno scorso ecco un riassuntino:
February 8, 1999
WASHINGTON, Feb. 8--Foods that score high in an antioxidant analysis called ORAC may protect cells and their components from oxidative damage, according to studies of animals and human blood at the Agricultural Research Service's Human Nutrition Research Center on Aging at Tufts in Boston. ARS is the chief scientific agency of the U.S. Department of Agriculture

ORAC, short for Oxygen Radical Absorbance Capacity, is a test tube analysis that measures the total antioxidant power of foods and other chemical substances.

Early findings suggest that eating plenty of high-ORAC fruits and vegetables--such as spinach and blueberries--may help slow the processes associated with aging in both body and brain.

"If these findings are borne out in further research, young and middle-aged people may be able to reduce risk of diseases of aging--including senility--simply by adding high-ORAC foods to their diets," said ARS Administrator Floyd P. Horn.

In the studies, eating plenty of high-ORAC foods:

Raised the antioxidant power of human blood 10 to 25 percent
Prevented some loss of long-term memory and learning ability in middle-aged rats
Maintained the ability of brain cells in middle-aged rats to respond to a chemical stimulus--a function that normally decreases with age
Protected rats' tiny blood vessels--capillaries--against oxygen damage
Nutritionist Ronald L. Prior contends, "If we can show some relationship between ORAC intake and health outcome in people, I think we may reach a point where the ORAC value will become a new standard for good antioxidant protection." (See table at end for ORAC values of fruits and vegetables.)

The thesis that oxidative damage culminates in many of the maladies of aging is well accepted in the health community. The evidence has spurred skyrocketing sales of antioxidant vitamins. But several large trials have had mixed results.

"It may be that combinations of nutrients found in foods have greater protective effects than each nutrient taken alone," said Guohua (Howard) Cao, a physician and chemist who developed the ORAC assay.

He and Prior have seen the ORAC value of human blood rise in two studies. In the first, eight women gave blood after separately ingesting spinach, strawberries and red wine--all high-ORAC foods--or taking 1,250 milligrams of vitamin C. A large serving of fresh spinach produced the biggest rise in the women's blood antioxidant scores--up to 25 percent--followed by vitamin C, strawberries and lastly, red wine

In the second study, men and women had a 13- to 15-percent increase in the antioxidant power of their blood after doubling their daily fruit and vegetable intake compared to what they consumed before the study. Just doubling intake, without regard to ORAC scores of the fruits and vegetables, more than doubled the number of ORAC units the volunteers consumed, said Prior.

Early evidence for the protecting power of these diets comes from rat studies by Prior, Cao and colleagues. Rats fed daily doses of blueberry extract for six weeks before being subjected to two days of pure oxygen apparently suffered much less damage to the capillaries in and around their lungs, Prior said. The fluid that normally accumulates in the pleural cavity surrounding the lungs was much lower compared to the group that didn't get blueberry extract.

Neuroscientist James Joseph and psychologist Barbara Shukitt-Hale at the center tested middle-aged rats that had eaten diets fortified with spinach or strawberry extract or vitamin E for nine months. A daily dose of spinach extract "prevented some loss of long-term memory and learning ability normally experienced by the 15-month-old rats," said Shukitt-Hale.

Spinach was also the most potent in protecting different types of nerve cells in two separate parts of the brain against the effects of aging, said Joseph.

"These cells were significantly more responsive when the animals ate diets fortified with high-ORAC foods--especially spinach--compared to unfortified diets," Joseph said. "The spinach group scored twice as responsive as the control animals."

Why spinach is more effective than strawberries--which score higher in the ORAC assay--is still a mystery. The researchers conjecture that it may be due to specific compounds or a specific combination of them in the greens.

More details on this research appear in an article in the February issue of Agricultural Research, ARS' monthly magazine. The story is also available on the World Wide Web at:
