Nutraceuticals dawn of a new era

Nutraceuticalsdawn of a new era


What are nutraceuticals

What are nutraceuticals ?

  • A food that provides medical or health benefits, including the prevention and treatment of a disease (Stephen De Felice, 1989)

  • Contraction of

    -nutrition and pharmaceutical.

  • Similar words

    - designer foods, functional foods,

    - genetically engineered foods

  • Taken in the form of

    -pills

    -capsule

    -powders and

    -tinctures.


C redit seminar

History is repeating

2000 BChere eat this root

1200 ADthis root is heathen, say this prayer

1500 ADprayer are superstitious, drink this potion

1900 ADthe potion is snake oil, swallow this pill

1950 ADthis pill is ineffective, take this antibiotic

2000 ADthe antibiotic is synthetic, eat this root

Veterinary nutraceuticals

Veterinary nutraceuticals

  • TEN COMMANDMENTS (John Walton):

    It must

  • improve performance effectively and economically.

  • have little therapeutic use.

  • not cause cross-resistance.

  • not involve in transfer of drug resistance.

  • not cause disturbance of gut normal flora.

  • not absorbed into edible tissues.

  • not be mutagenic or carcinogenic.

  • not permute salmonella shedding.

  • not give rise to environmental pollution, degradable.

  • non toxic to animal and human handlers.


Nutraceuticals for pigs

Nutraceuticals for Pigs

  • Enzymes:

    - amylase, protease and lipase.

  • FOS: (Fructo-Oligosaccharide)

    - derivative of inulin.

    - lactobacilli.

  • MOS: (Mannose-Oligosaccharides)

    - attracts pathogenic bacteria.

  • Nucleotides

    - improves immunity

    -absorption of nutrients


Equine nutraceuticals

Equine nutraceuticals

  • Superoxide dismutase (SOD)

    - antioxidant.

  • Dimethyl Glycine (DMG, pangamic acid)

    - increases phosphocreatine production in brain & muscle.

  • CoenzymeQ10 (ubiquinone)

    - powerful antioxidant.

    - heart diseases, high B.P and enhancement of immunity.


Pet nutraceuticals

Pet nutraceuticals

enhance reproductive efficiency

Bamboo leaves + ajwaine.

Retention of placenta

Marigold + alum

treatment of wound


Cardiovascular health

Cardiovascular health

  • $70 billion globally every year

  • $3 billion in 2004 to research cardiovascular health in U.S.

  • Risk factors:

    - elevated cholesterol levels

    - high blood pressure

    - diabetes.


Nutraceutical interventions

Nutraceutical Interventions

  • amenable to nutraceutical intervention.

  • nutraceuticals positively influence cardiovascular risk factors.

  • CholesterolReduction:

    - garlic (allicin and alliin)

    - fish oil (omega 3 fatty acid)

    - policosanol (plant waxes)


C redit seminar

  • Theaflavins(Black tea):

  • - squalene epoxidase.

  • Soy protein:

  • - prevent reuptake of cholesterol.

  • PMFs (citrus ):

  • - cholesterol biosynthesis/absorption.

  • Tocotrienols:

  • - reduce level of HMG-CoA reductase.


C redit seminar

- Sesamin.

- Gamma-amino butyric acid (GABA).

- Green tea catechins.

3. Diabetes:

  • c-reactive protein (diabetics)

  • vitamin C, vitamin-E,

  • omega 3-fatty acids e.g. fishoil.


Cancer prevention

Cancer prevention

  • Phytochemicals:

    - affect membrane structure and function.

    - signal transduction pathways regulating tumor growth and apoptosis.

    - immune function of host.

    - cholesterol metabolism.


C redit seminar

  • Indoles (cruciferous vegetables):

  • - estrogen metabolism.


C redit seminar

  • Isoflavones (soy foods):

  • Flavonoids (biological response modifiers):

    - quercetin (tomato, potato, onions).

    - kaempferol (kale and tomatoes).


C redit seminar

  • Carotenoids:

    Beta-carotenes (lung cancer):

    -carrots, potatoes, red peppers and pumpkins.

    Lycopene (prostate cancer):

    - tomatoes.

    Lutein (macular degeneration):

    - leafy green vegetables.


Areas of concern

Areas of concern

  • Safety and effectiveness:

    - nutraceuticals are not regulated by FDA.

    - only few has been studied rigorously.

    - in contrast prescription and over the counter drugs have been reviewed by FDA.

    - scientific studies are not designed for most.


C redit seminar

  • Purity

    - nutraceuticals are not regulated for purity.

  • Standardization

    - each ingredients in a dose should be present in precise quantity in standard form.


Interaction with drugs

Interaction with drugs

Nutraceuticals Affected drugs

  • Echinacea immunosuppressants

  • Garlic hypoglycemic drugs

    anticoagulants

  • Ginger anticoagulants


C redit seminar

  • Ginseng Corticosteroids,

    opiods.

  • Milk thistle Saquinavir.

  • St.John’s wort Benzodiazepines,

    digoxin and warfarin


Conclusion

Conclusion

  • Destined to play important role in future therapeutic developments.

  • They will continue to appeal because of convenience to today’s lifestyle.

  • Genuine research is going on and many potential agents are identified.

  • Nutraceuticals promote overall health status in addition to providing protection against diseases.

  • Very soon they will find a prominent place in clinical practice in treatment of diseases
