According to the American Institute for Cancer
Research, AICR, freeze-dried fruits have almost
the same antioxidant phytochemicals and
nutritional value as fresh fruit.
Antioxidant, Mutagenic, and
Antimutagenic Activity of Frozen Fruits
Evaluation of polyphenols, carotenoids, and
ascorbic acid showed considerable levels of
these compounds in frozen fruits, even after
freezing. These data suggest that frozen
fruits contribute to the prevention of
biological damages.

Acrylamide is a commodity chemical with many industrial
and laboratory uses. It is also formed from carbohydrate
and amino acid containing food by heating (primarily in
fried potato products, bread, coffee).
Epidemiological studies did not point to an association
between either occupational or dietary exposure and an
excess of cancer incidence.
Food Chem Toxicol. 2008 Apr;46(4):1360-4.
Microwave oven
Consumption of fried or broiled foods and
employment of microwave cooking,
because of formation of heterocyclic
amines, must be avoided because of
increasing risks of oral cancer including
the salivary gland tumors.
Arch Iran Med. 2007 Apr;10(2):227-32.
Microwave oven
Usage of microwave ovens for cooking and
supplementation of the diet, for example with
soy-isoflavones, which have been found to
suppress the occurrence of HCA-induced
(heterocyclic amines) breast cancers, should be
encouraged.

stomachs infected with H. pylori by affecting
the chemicals the stomach secretes in
response to infection.

Birth of Probiotics ?

A nobel prize winner of 1908 in physiology and
medicine
”The Prolongation of life”

of fermented milk product ”yoghurt”
Bacillus bulgaricus - Lactobacillus bulgaricus
Probiotics
beneficial ”life promoting” microorganisms
Reduce flatulence/stomach wind
Healing effect on allergy
Stimulate immun defence
Prevent Colon cancer
Stabilise intestinal microflora
Stimulate digestion of lactose
Reduce risk for infection
Some probiotic strains
of commercial food products
Lactobacillus acidophillus
Lactobacillus reuteri
Lactobacillus plantarum
Lactobacillus casei
Bifidobacterium lactis
Bifidobacterium infantis
Bifidobacterium longum
Birth of Prebiotics ?
Also early in the sixties
Dr. Burkitt and also Dr. Trowell
made clinical observations of great importance
and pointed out
the importance of some undigestible
matter of vegetable origin in the human diet
and the role of large intestine as an active
organ of the human body
Prebiotics
are suitable substrates for beneficial
microorganisms of the large intestine
Galacto oligosaccharides
Fructo oligosaccharides
Iso malto oligo saccharides
Xylo oligo saccharides
(Soluble dietary fibre components)
Beneficial effects of fermented milk
-It is well known that taking fermented foods
containing probiotics keeps our intestine healthy
-Claimed
Efficacy:
chronic
constipation,
probiotic effect, prevention of rotavirus infection,
gestroenteritis,
and
Traveler’s
diarrhea,
reduction of colon and bladder cancer, elevation
of NK cell activity, anti-hypertensive effect…..

food as early as 4,000 BC
