21. prebiotics
Nondigestible substances that provide a
beneficial physiological effect for the host by
selectively stimulating the favorable growth of
a limited number of indigenous bacteria.
Commonly known prebiotics are:
 Oligofructose .
 Inulin
Galacto-oligosaccharides
Lactulose

23. Phytochemicals could provide health benefits as;
•
Substrate for biochemical reactions
•
Cofactors of enzymatic reactions
•
Inhibitors of enzymatic reactions
•
Absorbents that bind to & eliminate undesirable
constituent in the intestine
•
Scavengers of reactive or toxic chemicals
•
Enhance the absorption and / or stability of essential
nutrients
•
Selective growth factor for beneficial bacteria
•
Fermentation substrate for beneficial bacteria
•
Selective inhibitors of deleterious intestinal bacteria

24. There are thousands of phytochemicals. But

42. ∗ Green tea: Antioxidant, reduces risk of CVD, enhances humoral and
cell mediated Immunity,
∗ Vegetables, fruits, whole grain, herbs, nuts and various seeds contain
an abundance of phenolic compounds, terpenoids, sulphur compounds,
pigments etc. that has been associated with protection / treatment of
certain disease conditions,

43. CONCLUSION
∗ Nutraceuticals are present in most of the food ingredients with varying
concentration
∗ Concentration, time and duration of supply of nutraceuticals influence
human health
∗ Manipulating the foods, the concentration of active ingredients can be
increased
∗ Diet rich in nutraceuticals along with regular exercise, stress reduction
and maintenance of healthy body weight will maximise health and
reduce disease risk
