Abstract
The date is an erect palm to 100 or 120 ft (30.5-36.5 m), the trunk
clothed from the ground up with upward-pointing, overlapping,
persistent, woody leaf bases. After the first 6 to 16 years, numerous
suckers will arise around its base. The feather-like leaves, up to 20 ft (6
m) long, are composed of a spiny petiole, a stout midrib, and slender,
gray-green or bluish-green pinnae 8 to 16 in (20-40 cm) long, and folded
in half lengthwise. Dates provide a wide range of essential nutrients, and
are a very good source of dietary potassium. The sugar content of ripe
dates is about 80%; the remainder consists of protein, fiber, and trace
elements including boron, cobalt, copper, fluorine, magnesium,
manganese, selenium, and zinc.
This study collected only three types of the commonly consumed dates in
Egypt were used. These types are well known because of their common
preference, popularity, economic price, as well as the high availability
through out the year
(1- Shamia 2- Shabah 3- Bartamoda) .
They were divided into four groups; each group consists of 5 pupils
1. The first group served as control group eating normal.
2. The second group eats 7 dates ” Shamia ” every morning .
3. The second group eats 7 dates ” Shabah ” every morning .
4. The second group eats 7 dates ” Bartamoda” every morning For 6
months
5. Determination the quantity according to the hadeeth Al-Bukhari
narrated in his Sahih from ’Amir ibn Sa’d that his father said: The
Prophet (Peace and Blessing upon Him) said: ”Whoever eats

’Ajwah dates every morning will not be harmed by poison or
witchcraft all that day until night comes.” Fath Al-Bari, 10/249.
After six months the effect of the different experimental dates on blood
components, stool components, oxidative stress enzymes, molecular
study DNA
And in vitro studied ”micro nucleus test” to determent it’s protective
from toxicity.
The results of the present study can be summarized as
follows:
1. The type 1 contained 87.89, 1.4, 0.5, 0.8, 2.2 and 361.66%
carbohydrates, protein, lipids, fiber ash and total carbohydrates
respectively. Concerning type 2, it was found to contain0.9, 0.2,
2.8, 0.6, 86.85 and 352.8 % protein, lipids, fiber, ash,
carbohydrates and total calories respectively, while in case of type
3 contained 2.5, 0.8, 2.9, 0.9, 83.78 and 352.32% of the same
content respectively.
2. from these results it could be noticed that, the type 3 the highest in
protein, lipid and fiber while type 1 contained high in
carbohydrates and total calories. type 1 was higher in zinc while,
type 2 was the best in calcium and iron. Type 2 and 3 had equal
amount of selenium which were higher than type1.
3. The levels after eating showed a significant difference with the
levels of hemoglobin before eating. There is no significant
difference between type 1&3 before eating and between type 1
after eating & type 2 before eating. The account of blood cells was

higher after eating on three types of dates than before the eating;
the best type was type 2 which caused the best account of blood
cells. The levels of blood platelets was improved after the eating
on all types of dates and the best one was type2 which had the best
effect and kept the levels of blood platelets in normal range.
4. The white blood cells account showed in type 1 levels4.73± 1. 13,
5.78± 1. 28 and 5.17± 0. 45Cmm for type 1, 2 and 3, respectively
before eating and 3.70 ± 0.50,4.30 ± 0. 97 and 4. 10 ± 0.36Cmm
for the same types respectively but after eating on the tested dates.
5. The glutathione (GSH) level in the control groups was lower than
that of other three groups (Table 6). Catalase activity in the liver
of children fed the type 3 was drastically reduced to less than half
the value obtained for control values. The values for the children
fed types 2 and 1 were not different from that of the control
values.
6. Glutathione-S-Transferase (GST) activity was found to increase in
the type 2 group when compared to the control. type 1 did not alter
the values when compared to the corresponding treated groups.
7. In Micronucleus test, there found cell with one nucleus, two
nucleuses, three nucleuses and more. In 0.5-1 % of normal cases
in all type of dates .But in our studied all student eat the different
types of date so the macronuclei was absent .
8. In molecular study DNA, the control sample shown very small
bright shadow as usual. But the kids eat date the bright shadow
was absent as indication to the DNA clearly.
