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.

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

reduced risk of cancer.

3 dietary supplements
3.Dietary supplements
  • Ketogenic diets- seizure control.

- breast cancer.

  • Edible mushrooms

- immunomodulation

- antitumor.

slide12
Zbar, nite-bite

- sucrose + proteins + uncooked starch

  • Glucosamine /chondroitin sulfates

- osteoarthritis

  • Dairy foods
  • Health drinks
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
  • Glucosamine and chondroitin

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)

slide21

Theaflavins(Black tea):

  • - squalene epoxidase.
  • Soy protein:
  • - prevent reuptake of cholesterol.
  • PMFs (citrus ):
  • - cholesterol biosynthesis/absorption.
  • Tocotrienols:
  • - reduce level of HMG-CoA reductase.
slide22
2.Hypertension:

- Sesamin.

- Gamma-amino butyric acid (GABA).

- Green tea catechins.

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.

slide28
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

  • Garlic hypoglycemic drugs

anticoagulants

  • Ginger anticoagulants
slide30
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
