Therapeutic Phytonutrients

Phytonutrients or phytochemicals are potentially used equally “chemoprotective agents” for a publish of human diseases. Nearly 50,000 species of higher plants receive got been used for medicinal purposes. Use of plants ranges from unsmooth preparations or extracts to refined extracts (whole or component of plants) in addition to unmarried molecular species. Some good known herbal remedies are obtained from cranberry, Echinacea, feverfew, garlic, Ginkgo biloba, St. John’s wart, saw palmetto etc. Some notable bioactive compounds used equally drugs include digoxin, digitoxin, morphine, reserpine, Taxol, vinblastine in addition to vincristine. Some 80% of the world’s population withal relies upon plants for primary wellness care. About 25% of prescription medicines are withal derived either straight or indirectly from plants (Farnsworth in addition to Soejarto, 1991). World merchandise inwards medicinal plants accounts for nearly 30% of the full drug market. Of the drugs prescribed inwards developed countries 25% derived from nearly 100 flora species (Comer in addition to Debus, 1996).


Phytonutrients or phytochemicals are biologically active substances naturally produced yesteryear plants for defence mechanisms against bacteria, viruses, fungi in addition to pest organisms. Most phytochemicals receive got antioxidant activity in addition to protect flora cells against oxidative harm due to Sun low-cal in addition to oxygen exposure. The phytochemicals  give plants their colour, season in addition to aroma. The term phytochemical is derived from the Greek prefix ‘fitos’ pregnant plant. These naturally occurring organic components of plants receive got physiological effects on human beings. These phytochemicals are rich inwards fruits, vegetables, beans, legumes, whole grains, herbs, spices in addition to nuts. It is estimated that at that topographic point are tens of thousands of phytochemicals receive got been identified. However alone nearly 1000 of these were identified in addition to alone nearly a 100 were genuinely analyzed in addition to tested. Unlike the essential nutrients (proteins, carbohydrates, fats, minerals in addition to vitamins) that needed for increment in addition to metabolism in addition to other trunk functions, phytonutrients are considered non-essential nutrients. These non-nutritive flora chemicals are non required yesteryear the human trunk for sustaining life. However epidemiological studies propose that consumption of a diet rich inwards fruits in addition to vegetables is associated amongst a reduced opportunity of chronic diseases.

Biological functions

Antioxidant activity – The consumption  of for certain phytonutrients trim down the opportunity of cancer yesteryear neutralizing  free radicals or reactive oxygen species (ROS) or oxidants responsible for the attack of diseases.  The phytonutrients amongst antioxidant activity include allyl sulphides (onions, garlic), carotenoids (fruits, carrots), flavonoids (fruits, vegetables) in addition to polyphenols (tea, grape fruits).
Hormonal action – Isoflavones (phytoestrogens inwards soybeans) deed similar human estrogens in addition to aid to trim down menopausal symptoms in addition to osteoporosis (porous bones).
Enzyme stimulants – Indoles (cabbage) create enzymes that lower the activity of estrogens in addition to trim down the opportunity of thorax cancer. The protease inhibitors are flora inwards soy in addition to beans in addition to terepenes inwards citrus fruits in addition to cherries.
DNA protectors – saponins (beans) interfere amongst deoxyribonucleic acid replication thereby preventing the multiplication of cancer cells. Caposaicin flora inwards hot peppers protect deoxyribonucleic acid from carcinogens.
Antibacterial activity – allicin (garlic) has antibacterial properties.
Anti-adhesion action – proanthocyanidins (cranberry) forestall bacterial adhesion human cells.
Cholesterol control – Phytosterols regulate the cholesterol uptake inwards the intestine.

Biological characteristics

The phytonutrients are readily available to human trunk later on ingestion. Flavonoids are H2O –soluble in addition to carotenoids are fat-soluble phytonutrients. The absorption of carotenoids needs the presence of skillful fats inwards the intestine. Certain phytonutrients deed equally antioxidants, scavenge gratis radicals, in addition to inhibit prison theatre mobile telephone decease or apoptosis.

Disease -preventive  benefits

1. Reduce oxidative harm to the cells.
2. Facilitate cell-to-cell communication.
3. Stimulate detoxification enzymes in addition to forestall dietary substances becoming carcinogenic.
4. Enhance the immune response.
5. Reduce inflammation.
6. Prevent deoxyribonucleic acid harm in addition to assist deoxyribonucleic acid repair.
7. Modify cellular uptake of hormones.
8. Help forestall cardiovascular in addition to oculus diseases.
9. Help forestall various forms of cancer.
10. Act equally antibacterial or antiviral or anti-aging agents.

Kinds of phytonutrients

There are many types of phytonutrients; about of the best known ones are chlorophyll, carotenoids, flavonoids in addition to organosulfur compounds.
Chlorophyll is a chemoprotein flora inwards the green pigments of plants. It is related to protoheme, the reddish paint of blood. Chlorophyll is an extremely healthful substance, which tin flaming live obtained from light-green leafy vegetables (broccoli, Brussel sprouts, cabbage, lettuce in addition to spinach), wheat grass, alfalfa, parsley in addition to algae (chlorella in addition to spirulina). Chlorophyll promotes formation of haemoglobin in addition to reddish blood corpuscles. Chlorophyll treats bad breath. Chlorophyll fights infections. Chlorophyll is used for constipation, detoxification in addition to injure healing. Green vegetables high inwards chlorophyll content assist inwards loosening in addition to cleansing colon.
Carotenoids are a grouping of yellow, orange, reddish in addition to light-green flora pigments amongst strong antioxidant activity. They are idea to cancer – preventive properties yesteryear inhibiting abnormal prison theatre mobile telephone growth.  Carotenoids may play a critical role inwards the cardiovascular in addition to glucose wellness of obese individuals. More than 600 carotenoids receive got been flora inwards plants. About one-half of the roughly l carotenoids inwards the human diet are absorbed into blood stream. Lycopene in addition to beta-carotene each constitute 30% of plasma carotenoids. Orange carotenoids include alpha, beta in addition to gamma carotenes. Red carotenoids constitute lycophene in addition to astaxanthin. Yellow carotenoids are lutein in addition to zeaxanthin.
Flavonoids are the most various in addition to best studied grouping of phytochemicals. They are H2O –soluble phytochemicals in addition to about of which receive got red, bluish in addition to regal pigments. In fact to a greater extent than than 6000 flavonoids that guide house inwards plants receive got been described.  The primary subclasses include catechins, flavonols, flavanones, flavones in addition to Isoflavones (phytoestrogens). Out of all the phytochemicals inwards fruits in addition to vegetables, it is the flavonoids that nosotros eat inwards large quantity inwards our diet. Flavonoids deed equally antioxidants, protect cholesterol from oxidation to dangerous cholesterol oxides, inhibit the formation of blood clots in addition to receive got anti-inflammatory in addition to antitumor action. One study flora that men amongst the highest consumption of flavonoids had 60% less mortality from pump illness in addition to 70% lower opportunity of stroke than the depression flavonoids consumer. Consumption of flavonoids was responsible for 25% of the departure inwards mortality rates inwards a study conducted inwards seven –European countries(UC Davis report).
Organosuphur compounds (isothiocyanates) are flora inwards the allium in addition to brassica vegetables.  Isothiocyanates originate equally glucosinolates inwards plants in addition to are converted into isothiocyanates yesteryear the enzyme myrosinase.  Allium vegetables include garlic, leeks, onion, in addition to shallouts.They incorporate flavonoids, vitamin C in addition to selenium. They receive got been shown to receive got cancer protective in addition to cardioprotective properties. Brassica vegetables include broccoli, Brussels sprouts, cabbage, Chinese cabbage, cauliflower, kale in addition to watercress. They likewise incorporate flavonoids in addition to vitamin C.  They are protective agents for many forms of cancer. Sulphur compounds are likewise flora inwards grains, wheat germs, oat repast in addition to inwards fruits similar figs, plantain, papaya in addition to pino apple.

The wellness promoting belongings of phytochemicals is ane of the of import reasons for adding vegetables, fruits, whole grains in addition to other flora foods inwards diet. It is inferred that most phytochemicals involve to piece of employment amongst other phytochemicals to create desired wellness effects.
