including prevention of diseases or promotion of health”


Diabetes – Garlic, momordica

                 Classification of Nutraceuticals

➢ Inorganic mineral supplements

➢ Vitamin supplements

➢ Digestive enzymes

➢ Probiotics

➢ Prebiotics

➢ Dietary fibres

➢ Health drinks

➢ Antioxidants


➢ Herbs as functional foods



              Classification of Nutraceuticals

Inorganic mineral supplements:


➢ Large number of elements control variety of physiological and

  biochemical functions of human body


➢ Most of the minerals are provided through diet, Deficiency of

  minerals in food may lead to various diseases


Eg: Calcium – Imp in the treatment of bone loss and prevention,

  sufficient intake of Ca post menopause significantly reduce the risk

  of bone fracture

➢ Vit B complex – Specific vitamin B recommended for to combat high

  levels of homocysteine


➢ Niacinamide deficiency – Neurological and skin problems


➢ Vitamin C – Anti oxidant, Necessary for proper maintenance for







               Classification of Nutraceuticals


Digestive enzymes:


➢ Use to help absorb and digest food material


➢ Pepsin of digestive juice – Digestive aid for proteins


➢ Amylase – Digest carbohydrates


➢ Pancrilipase – Breakdown of fat in small intestine


➢ Papain and bromelain – In digestive disorders







              Classification of Nutraceuticals



➢ Describing as a living organisms


➢ When ingested with or without food improves the intestinal

  microbial balance and consequently the health and functioning of

  large intestine


➢ Approximately 95% of bacteria found in colon of human body, some

  of them are useful and some of them harmful


➢ Natural balance between these two play an imp role in the health

  and functioning of large intestine




              Classification of Nutraceuticals

Eg: Bioyoghurts – Lactobacillus acidophilus reduces the incidence of

  vaginal infections


   Bifido bacteria found in yoghurt prevent young children suffering

  from diarrhoea




➢ Food components that escape digestion by normal human

  digestive enzymes and reach the colon after passage through the

  stomach and small intestine


➢ selectively promote the growth of probiotics




              Classification of Nutraceuticals

Eg: Fructo oligosaccharide used in food supplements encourage the

  growth of Bifido bacteria already present in the gut


Dietary fibres: Necessary for our body to function properly


Water insoluble fibre:


➢ Absorbs water to certain extent


➢ Mainly contributes to bulking of stool


➢ Allows quick passage of wastes


Eg : Whole grain cereals, wheat, fruits and vegetables





                 Classification of Nutraceuticals

Water soluble fibre:


➢ Get dissolved in a water and forms a gel that binds the stool


➢ Slows down the absorption of glucose and reduce the cholesterol



Eg : Oats, legumes, fruits and vegetables


Health drinks:


➢ Health drinks are incorporated with antioxidants, Vit A, C and E and

  herbal extracts


Eg : Tropicana fruit juice fortified with Calcium provide 365 mg/250 ml



                 Classification of Nutraceuticals

Anti oxidants:


➢ Deficiency of antioxidants leads to variety of diseases like diabetes,

  cardiac diseases, arthritis etc


True antioxidants:


➢ React with free radicals and block the chain reaction of free



Antioxidant synergists:


➢ Very low antioxidant potential, but enhance the effect of true

  antioxidants by reacting with heavy metals which catalyse the auto



              Classification of Nutraceuticals



➢ Vitamin C – Citrus fruits

➢ β-carotene – Carrot, sweet potato


➢ Rutin – Buck wheat, eucalyptus


➢ Quercetin – Onion, apple, black grapes


➢ Betalaines – Beet root






                 Classification of Nutraceuticals


Poly unsaturated fatty acid (PUFA)


➢ Human body is capable of synthesizing most of the fatty acids

  except two major Poly unsaturated fatty acids omega-3-fatty acid

  and omega -6-fatty acid


➢ These are precursors for arachidonic acid and docosohexanoic acid



➢ These acids found to regulate Blood pressure, heart rate, blood

  clotting etc





               Classification of Nutraceuticals


➢ Essential for the development of foetus and also during first 6

  months after birth


➢ Breast milk is a rich source for DHA




Herbs as functional foods: Various herbs used in prevention of disease


Eg: Garlic, spirulina, momordica, flax seed, tomato, turmeric, Ginkago

  biloba etc








➢ Nutraceuticals – Nutritional value as well as health benefits

➢ Classification – Inorganic mineral supplements, Vitamin supplements

  Digestive enzymes, Probiotics, Prebiotics, Dietary fibres, Health drinks

➢ Antioxidants, Poly unsaturated fatty acids, Herbs as functional foods
