3. Introduction:
The combination of consumer desires, advances in food
technology, and new evidence-based science linking diet to
disease and disease prevention has created an unprecedented
opportunity to address public health issues through diet and
lifestyle. Widespread interest in select foods that might promote
health has resulted in the use of the term “functional foods.”
Although most foods can be considered “functional,” in the
context of
this report the term is reserved for foods and food components
that have been demonstrated to provide specific health benefits
beyond basic nutrition. The term functional food is thus arbitrary,
but it is nonetheless useful since it will convey
Functional foods

Functional Foods:
The term ‘functional’ is sometimes used to describe
foods and drinks that are enriched with particular
nutrients or substances that have the potential to
positively influence health over and above their basic
nutritional value. Functional foods are usually similar to
foods that are consumed as part of our usual diet e.g.
yogurt, drinks, bread
5. Why do we need functional foods?
Consumer interest in the relationship between diet and
health has increased substantially in world. There is
much greater recognition today that people can help
themselves and their families to reduce the risk of illness
and disease and to maintain their state of health and well
being through a healthy lifestyle, including the diet

16. Nutraceutical food
INTRODUCTION:
The term "Nutraceutical“ was coined from "nutrition“ and
"pharmaceutical" in 1989 by Stephen DeFelice, MD, founder and
chairman of the Foundation for Innovation in Medicine (FIM),
Cranford, NJ.1
According to
DeFelice, Nutraceutical can be defined as, "a food (or
part of a food) that provides medical or health benefits, including
the prevention and/or treatment of a disease."
23. All therapeutic areas such as,
1. Sleeping disorders
2. Digestion problems
3. Prevention of certain cancers (Colorectal cancer)
4. Osteoporosis
5. Blood pressure
6. Cholesterol lowering (garlic)
7. Neurological disorders (Autism)
8. Diabetes etc.
24. Nutraceutical have the potential to play a role in healthy eating
and to contribute to the prevention and treatment of diseases.
Since new molecule is difficult to discover and more expensive
and risky then ever before, many pharmaceutical companies are
now trying to nutraceutical so that there is undoubtedly a very
huge and growing market.
The belief among consumers that these “food like substances”
are either harmless or least toxic as compared to conventional
pharmaceuticals.
Advantages
25. The role of Nutraceutical in treating inappropriate
Dietary habits are seen as contributing to the leading
Cause of deaths of due to coronary heart
disease,Certain type of cancers etc.
Nutraceutical are gaining popularity as people are
Relying on them for safeguarding their health and
Avoiding side effects associated with drugs as well
Long history of use and better patient tolerance as Well
as public acceptance.
Plants constitute to be a major source of new lead
Generation of nutraceutical.
26. Disadvantages
Not subjected to same testing and regulations as
pharmaceuticals
Majority not regulated by FDA in USA
Companies creating unregulated products to create a wide
profit margin
Bioavailability of nutrients is lower
No regulatory definition
27.
28. Conclusion:
Nutraceutical may be beneficial to our health but
we are still earning about their benefits and
possible harmful effects.
Government regulatory bodies also face
challenges n this new category of health products,
which lies between foods and drugs.
Health professional , Nutritionists and regulatory
toxicologist should strategically work together to
plan appropriate regulation to provide ultimate
health and therapeutic benefit to mankind.

31. Probiotics
Probiotics are ‘live microorganisms which, when
administered in adequate amounts, confer a
health benefit on the host.” So, essentially,
probiotics are living bacteria lining your
digestive tract that can help your overall health
34. Function of probiotic food
• Probiotics encompass a wide range of bacterial strains
• Probiotics must be taken regularly and survive their passage
through the gastro-intestinal tract
• The vehicle by which probiotics are delivered, and dose, are
also important
• Process food properly
• Keep your skin healthy and glowing
• Eliminate yeast and fungal infections
• Maintain a healthy weight or lose weight
• Oust certain pathogens that cause illness
38. Prebiotics are food ingredients that induce the growth or
activity of beneficial microorganisms (e.g., bacteria and
fungi). The most common example is in the gastrointestinal
tract, where prebiotics can alter the composition of
organisms in the gut microbiome.
Commonly known prebiotics are:
Oligofructose
Inulin
Galacto-oligosaccharides
Lactulose
Prebiotics
39. • Increase the number or activity of bifidobacteria
and lactic acid bacteria.
• Improving digestion
• The effectiveness and intrinsic strength of the
immune system.
Function
It is generally agreed that Functional food is any food that has bioactive compounds (beta-carotene, lycopene, resveratrol, ferulic acid, etc.), among the most commonly known are grapes, strawberries, apples, etc; and that it has been proven they can cause a benefit effect on human health. On the other hand, and closely related, nutraceuticals are the chemical compounds (or dietary supplements) that can improve health.
Nutraceuticals = functional food + dietary supplements. Hence, functional food is a part of nutraceuticals.
Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. We usually think of bacteria as something that causes diseases. But your body is full of bacteria, both good and bad. Probiotics are often called "good" or "helpful" bacteria because they help keep your gut healthy
Probiotics are also available as dietary supplements. It has been suggested that probiotics be used to treat problems in the stomach and intestines. But only certain types of bacteria or yeast (called strains) have been shown to work in the digestive tract.
In diet, prebiotics are typically non-digestible fiber compounds that pass undigested through the upper part of the gastrointestinal tract and stimulate the growth or activity of advantageous bacteria that colonize the large bowel by acting as substrate for them.[1] They were first identified and named by Marcel Roberfroid in 1995. As a functional food component, prebiotics, like probiotics, are conceptually intermediate between foods and drugs. Depending on the jurisdiction, they typically receive an intermediate level of regulatory scrutiny, in particular of the health claims made concerning them
The prebiotic definition does not emphasize a specific bacterial group. Generally, however, it is assumed that a prebiotic should increase the number or activity of bifidobacteria and lactic acid bacteria[citation needed]. The bifidobacteria and the lactic acid bacteria (LABs) are important as these groups of bacteria may have several beneficial effects on the host, especially in terms of improving digestion (including enhancing mineral absorption and the effectiveness and intrinsic strength of the immune system.A product that stimulates bifidobacteria is described as a bifidogenic factor, a concept that overlaps, but is not identical with, being prebioti
