This document discusses the role of food biotechnology in health maintenance. It explains that food biotechnology uses genetic modification to create foods with desired traits. This can help overcome hunger by increasing crop yields and nutritional value, such as golden rice which contains beta-carotene to prevent vitamin A deficiencies. It also discusses how edible vaccines produced in foods through biotechnology can help prevent diseases by inducing antibody responses when consumed. The document outlines other benefits of genetically modified foods like their ability to help prevent diseases, support a healthy environment, and proposes future health applications of biotechnology in foods.

3. 1. Food Biotechnology:-
• Application of technology to modify genes of
animals, plants, and micro-organisms to create new
species with desired characteristics.

4. 2. How Can Food Biotechnology Helps In Health
Maintenance?
 Overcome Hunger and Malnutrition
 Prevent Diseases
 Vaccines
 Fight Against Cancer
 Healthy Environment

5. 3. Overcome Hunger and Malnutrition:-
 Yield of more Crops in less time and on less area.
 Genetic Boost to disease fighting nutrients of
plants.
 Genetically Modified Food with High Nutritional
value.
 Example:- Golden Rice.
 Golden Rice contain β-carotene which is a
precursor to Vitamin A
Someone dies of
Starvation
every 10 second

6. Class/Compone
nt
Source Benefits
• carotenoids
α-carotene Carrot Neutralize free radicals that cause damage
to cells.
lycopene tomato May reduce risk of prostate cancer
β-carotene Fruits and vegetables Beneficial for good eye sight
Lutein Green vegetables Maintain healthy vision
• Sulfides
Diallyl sulphide Onion, garlic, olives Helps in maintaining healthy immune
system
• Proteins
Soybean protein Soy beans and soy based
products
May reduce heart diseases

7. Genetically Modified Food With High
Nutritional Value:-
 Food derived from the organism where
genetic material (DNA) has been modified in
a such a way that does not occur naturally.
i.e. through the introduction of a gene from a
different organism.
 GM food contain High Nutritional Value.
 Golden Rice:-
 High amount of β-carotene, which is a
precursor to Vitamin A.
2 million children die
each year of Vitamin
A deficiency

8. 4. Edible Vaccines:-
• Edible Vaccines are made through the process called Bio
pharming.
• Pathogen protein gene is cloned.
• Gene is inserted into DNA of plant.
• Human consume plant.
• Body produce antibodies against pathogen protein.
• Human are immunized against pathogen.
• Vaccine Banana against polio, measles and diarrhea.

10. Vaccines Vector used Disease
Hepatitis B virus Potato, tobacco Hepatitis B
Rabies Virus Tobacco Rabies
HIV virus Tomato AIDS
Norwalk virus Tobacco, Potato Nausea, Stomach
cramps
Vibrio Cholera Potato Cholera

11. Why Edible Vaccine?
Provide mucosal
immunity at various
sites by secreting
antibodies.
No need of
worrying about Re-
Use, Misuse and
sterilization
Cheap
No need of
purification
Heat Stable

12. 5. Prevent Diseases:-
• Potatoes are developed which contain Insulin or GAD to
enhance uptake of antigens by M cells.
• To elicit autoimmune response which can cause Diabetes I.
• Tobacco are developed which contain less amount of
Nicotine, thus prevent from harmful effects of too much
Nicotine consuming

13. 6. Healthy Environment:-
• Reduce Green House Effect.
• Fast Growing Plants Utilizes CO2 More Efficiently
• GM Crops Are Capable Of Capturing And Storing
Carbon from atmosphere.
In 2007, 274 million acres of biotech crops
resulted in a 31.3 billion pound reduction in
CO2

14. 7. Future Towards Health Care:-
 Tomatoes are being in process of genetic modification with
a potential to fight against cancer.
 Adaptation in Food supply of GM potatoes that contain less
Acrylamide (Cancer causing chemical.) Approved From
FDA.
