to reduce the risk of cataracts in women Oxidative damage of crystalline proteins is the main cause of cataracts. Antioxidant nutrients can play a role in preventing cataracts.lutein and its stereo isomer zeurnina are the only two types of carotene that are naturally present in the crystal, which are powerful antioxidant nutrients, filter harmful short-wave blue light, and help stabilize the integrity of the membrane.study has fully recognized the protective effect of yeast intake from diet on reducing the risk of cataracts.studies have shown that a high dietary intake of
(6.7mg/

)
of serotonin reduces cataract risk by
18 per cent compared to a low dietary intake of
(1.2mg/
days
)

.Brief The main function of the eye lens is to collect light and focus it on the retina, which must be kept clear in order to achieve this function correctly through the lifetime. The correct function of eye tissue requires light and oxygen, however, excessive exposure to these two media can lead to membrane lipid peroxidation due to the formation of reactive oxygen family, thereby damaging the crystalline body and damaging the crystal protein. At a young age, the production of damaged crystalline proteins is inhibited by antioxidant enzymes in the crystal and the activity of small antioxidant molecules such as vitamin
C
, vitamin
E
and carotenoids; As the eyes age, these defense mechanisms gradually weaken or fail, leading to the accumulation and precipitation of oxidizing proteins, resulting in crystal turbidity, the increase in turbidity is cataracts.the oxidation reaction of the crystal is one of the main causes of cataracts, the fact that antioxidant nutrients may play an important role in the prevention of cataracts.and its isomer zelin, are the two main components of macular pigment and the only two types of carotene that are naturally present in the crystal. It is well known that flafonin and zelk can effectively reduce age-related macular degeneration (AMD)
(AMD)
. Epidemiological and interventional studies have shown that high dietary intake of lite and zelin, as well as increased levels of the resulting serotonin and zelin, reduces the risk of
AMD
and improves visual function in patients with
AMD
.the theoretical basis for the protective effects oflutein and zelk on the eye, including the protective effects on the retina and crystals, stems from the
ability of these two types of
carotene to filter harmful short-wave blue light



; These functions are thought to play an important role in helping to reduce light-induced oxidative damage caused by reactive oxygen intermediates, the pathogenesis of cataracts attributed to this reactive oxygen intermediate.A positive statement issued by France's National Food Safety Agency
(AFSSA)
states that flafel contributes to the protection of the retina and crystals from oxidation, and that flafonin is one of the components of the retina and crystalline body, supporting the general health relationship between lolitin and eye health. Observational and interventional studies have also confirmed that dietary intake of yelutin and zelin and
/
or their serum levels has a protective effect on reducing cataract risk.new evidenceImportant new evidence on the beneficial effects of dietary loculin in reducing cataracts comes from a U.S. study published in

study.used a

validated semi-quantitative food frequency questionnaire
(SFFQ)
to collect detailed information on antioxidant intake from food and supplements in the year prior to the
1993
study. For each food item, its quantity is evaluated using a
9
-point scoring dial, ranging from "Never" to "
6
times a day or
6
or more times a day." The average daily nutrient intake
(

) maintained by the Harvard School of Public Health, adjusted for total energy intake
(TEI)

A multivariate analysis of relative risk estimates used to assess the relationship between the highest five-point value of cataract and nutrient intake and the lowest five-point value after adjusting for possible cataract risk factors. The results showed that women with the highest dietary elutin and zebeth intake (an average of
6.7 mg/
days) had a
18% reduced risk of cataracts compared to women with a minimum intake of
1.2 mg/

days). Vitamin

from food and supplements also reduced cataract risk
(

, but there was no significant correlation between vitamin
E
intake from food and reduced cataract risk. All other nutrients assessed did not show any statistically significant trend in reducing cataract risk.conclusionsthis study strongly supports previously published studies on the use of prologue and zelk to help reduce the risk of cataract development.
