To study the causes of cancerous food in our

environment.

To study the effect of food preservative and

additive on food.To gain more information about the

cancerous food.

To discuss the data that related to the

cancerous food.

What Is Cancer?

Cancer begins as a single abnormal cell that beginsto multiply out of control. Groups of such cells form

tumors and invade healthy tissue, often spreading toother parts of the body.

Carcinogens are substances that promote thedevelopment of cancerous cells. They may come fromfoods, from the air, or even from within the body.

Some vitamins in plant foods are known to be

inhibitors. Dietary fat, on the other hand, is known tobe a promoter that helps the abnormal cells growquickly.

Food Preservative is natural or synthetic

chemical that is added to food products to

prevent decomposition by microbial growth or by

undesirable chemical changes. Food preservatives may be :

a) Antimicrobial (inhibit the growth of bacteria and

fungi and mold growth)

b) Antioxidants such as oxygen absorber(inhibit theoxidation of food constituents)

Food additives are substances added to food to

preserve flavor or improve its taste and

appearance.

1.CARCINOGEN

Definition:

Any substance, radionuclide or radiation, that is

an agent directly involved in the exacerbationof cancer or in the increase of its propagation.

Several radioactive substances are considered

carcinogens, but their carcinogenic activity is

attributed to the radiation, (gamma rays andalpha particles.)

Examples : inhaled asbestos, certain dioxins, and

tobacco smoke.


6/14

There are many natural carcinogens.

Aflatoxin B1, which is produced by

the fungus Aspergillus flavus growing on

stored grains, nuts and peanut butter, is anexample of a potent, naturally-

occurring microbial carcinogen.

Certain viruses such as Hepatitis B and human

papilloma viruses have been found to causecancer in humans.


7/14

SATAY

Research has shown that grilling causes

certain foods, particularly fatty meats, to

create a carcinogen. Eating satay together with carbon after

barbequing can cause cancer.

However, the risk is low and can be reduced

even further with some healthy grillinghabits and eat cucumber (anti-carsinogenic)

after eating satay.

2.SODIUM NITRITE

Definition:

Sodium nitrite, with chemical formula NaNO2, isused as a color fixative and preservative in meats

and fish. When pure, it is a white to slight yellowish

crystalline powder. It is very soluble in water.

As a food additive, it serves a dual purpose in thefood industry since it both alters the color of

preserved fish and meats and also prevents growthof Clostridium botulinum, the bacteria whichcauses botulism.

Examples :Bacon, ham, hot dog, luncheon meats,smoked fish


9/14

Found naturally in tea, coffee, and cocoa. Also addedto many soft drinks. It is one of the few drugs astimulant added to foods.

Promotes stomach-acid secretion (possibly increasingthe symptoms of peptic ulcers), temporarily raises

blood pressure, and dialates some blood vessels whileconstricting others.

Excessive caffeine intake results in "caffeinism," withsymptoms ranging from nervousness to insomnia.These problems also affect children who drink

between 2 to 7 cans of soda a day. Caffeine may alsointerfere with reproduction and affect developingfetuses. Experiments on lab animals link caffeine tobirth defects such as cleft palates, missing fingersand toes, and skull malformations.

4.ACRYLAMIDE

Definition:

Acrylamide is a chemical that is formed when

certain starchy foods (like potatoes and flour)are heated at high temperatures. It is also

formed on coffee beans as they are roasted.

Researchers estimate that if you are a heavy

consumer of the foods that contain acrylamide,the exposure will give you about a 15 in 10,000

chance of contracting cancer over your lifetime.

Other health risks for acrylamide exposure have

not yet been quantified.


11/14

The Dutch study found that women who absorbed

more acrylamide were twice as likely to developovarian or womb cancer as those who ingested a

smaller amount.

The findings show a positive association between

an increased acrylamide-haemoglobin level and the

development of breast cancer after adjustment forsmoking behaviour.

The risk of breast cancer doubles with a tenfold

increase in the acrylamide-haemoglobin level.

The study also shows a stronger association forestrogen receptor positive breast cancer.

DONUTS

With their potent mix of sugar, white flour,

hydrogenated oils and acrylamides, they're one

of the worst cancer foods you can possibly eat.FRENCH FRIES

The amount of acrylamide found in a large

order of French fries at a fast food restaurant

is at least 300 times higher than what theEnvironmental Protection Agency allows in a

glass of drinking water.


13/14

The time has come to reconsider the causes

of cancer

Food does not seem to play a big role in the

cause of cancerMan-made chemicals could play a much

bigger role in the cause of cancer than

suspected

Human exposure to man-made chemicalscould be through food, drink, inhalation.
