Frutas
Cor Laranja
A Zeaxantina e Luteína são carotenóides presentes nas
frutas e legumes amarelo-alaranjados. O consumo desses carotenóides é essencial
para a preservação da mácula ocular e evitar problemas de visão relacionados à
velhice. Estes nutrientes reduzem os riscos de degeneração macular e o risco de
câncer de próstata,ajudam a diminuir o colesterol LDL e da pressão arterial,
promovem a formação de colágeno e articulações saudáveis, combatem os radicais
livres nocivos,incentivam o equilíbrio alcalino, e trabalho com magnésio e
cálcio para construir os ossos.Nutrientes saudáveis nas laranjas são abundantes
e diversificados. O fruto é de baixa calorias, não contém gorduras saturadas ou
colesterol, mas é rica em fibra dietética, pectina, que é muito eficaz em
pessoas com excesso de peso corporal. A pectina, pela sua ação como laxante ,
ajuda a proteger a membrana mucosa do cólon, diminuindo seu tempo de exposição
a substâncias tóxicas, assim como por ligação a produtos químicos que causam o
cancer no cólon. A pectina foi mostrada também para reduzir os níveis de
colesterol no sangue diminuindo a sua re-absorção no cólon por ligação a ácidos
biliares no colon.A laranja, como outros citrinos, é uma excelente fonte de
vitamina C, fornece cerca de 60% de DRI;a vitamina C é um poderoso antioxidante
natural. O consumo de alimentos ricos em vitamina C ajudam o corpo desenvolver resistência
contra agentes infecciosos .A laranja contém uma variedade de fitoquímicos.
Hesperetina e Narigenina são flavonóides encontrada em frutas cítricas.
Naringenina é encontrado para ter um efeito bio-activo sobre a saúde humana
como antioxidante, captador de radicais livres, anti-inflamatória e moduladora
do sistema imunitário.Esta substância foi também mostrada que reduzir a lesão
oxidante para ADN em estudos in vitro. As laranjas também contem muito bons
níveis de vitamina A, e outros flavonóides antioxidantes, tais como alfa e
beta-caroteno, beta-criptoxantina, zea-xantina e luteína. Estes compostos são
conhecidos por terem propriedades antioxidantes. Vitamina A também é necessária
para a manutenção de membranas mucosas saudáveis e de pele e é essencial para a
visão. Consumo de frutas naturais ricos em flavonóides ajudam o corpo para
proteger do pulmão e de alguns tipos canceres da cavidade oral. Frutas laranjas
são uma boa fonte de vitaminas do complexo B, como tiamina, piridoxina e
folatos. Contém uma quantidade muito boa de minerais como potássio e cálcio. O
potássio é um componente importante dos fluidos de células e do corpo que ajuda
na taxa de controle cardíaco e pressão sanguínea. É cientificamente provado que
as frutas cítricas, especialmente as laranjas, em virtude de sua riqueza em
vitaminas e minerais, tem muitos benefícios à saúde. Além disso, os compostos
não nutrientes encontrados nos citricos tais como antioxidantes fito-químicos,
fibras dietéticas solúveis e insolúveis,foram entendidas como úteis para
redução do risco de cancer e de muitas doenças crônicas como a artrite, a
obesidade e as doenças coronarianas. — com Adriana

The Orange
Fruits
Contain beta-carotene, zeaxanthin, flavonoids,
lycopene, potassium, and vitamin C. These nutrients reduce age-related macula
degeneration and the risk of prostate cancer, lower LDL cholesterol and blood
pressure, promote collagen formation and healthy joints, fight harmful free
radicals, encourage alkaline balance, and work with magnesium and calcium to
build healthy bones.Nutrients in oranges are plentiful and diverse. The fruit
is low in calories, contains no saturated fats or cholesterol, but is rich in
dietary fiber, pectin, which is very effective in persons with excess body
weight. Pectin, by its action as bulk laxative, helps to protect the mucous
membrane of the colon by decreasing its exposure time to toxic substances as
well as by binding to cancer causing chemicals in the colon. Pectin has also
been shown to reduce blood cholesterol levels by decreasing its re-absorption
in the colon by binding to bile acids in the colon.Oranges, like other citrus
fruits, is an excellent source of vitamin C ,provides about 60% of DRI; Vitamin
C is a powerful natural antioxidant. Consumption of foods rich in vitamin C
helps body develop resistance against infectious agents and scavenge harmful,
pro-inflammatory free radicals from the blood.Orange fruit contains a variety
of phytochemicals. Hesperetin and Narigenin are flavonoids found in citrus
fruits. Naringenin is found to have a bio-active effect on human health as
antioxidant, free radical scavenger, anti-inflammatory, and immune system modulator.
This substance has also been shown to reduce oxidant injury to DNA in vitro
studies.Oranges also contain very good levels of vitamin A, and other flavonoid
antioxidants such as alpha and beta-carotenes, beta-cryptoxanthin, zea-xanthin
and lutein. These compounds are known to have antioxidant properties. Vitamin A
is also required for maintaining healthy mucus membranes and skin and is
essential for vision. Consumption of natural fruits rich in flavonoids helps
body to protect from lung and oral cavity cancers.It is also a very good source
of B-complex vitamins such as thiamin, pyridoxine, and folates. These vitamins
are essential in the sense that body requires them from external sources to
replenish.Orange fruit also contains a very good amount of minerals like
potassium and calcium. Potassium is an important component of cell and body
fluids that helps control heart rate and blood pressure through countering
sodium actions.Citrus fruits, as such, have long been valued for their
wholesome nutritious and antioxidant properties. It is scientifically
established that citrus fruits, especially oranges, by virtue of their richness
in vitamins and minerals, have many proven health benefits. Moreover, it is now
beginning to be appreciated that the other biologically active, non-nutrient
compounds found in citrus fruits such as phyto-chemical antioxidants, soluble
and insoluble dietary fiber have been found to be helpful in reduction in the
risk for cancers, many chronic diseases like arthritis, and from obesity and
coronary heart diseases.
