THE PROBLEM ON THE LACK OF INGESTION OF CALCIUM AND MAGNESIUM IN JAPAN AND CORAL POWDER

The oldest data of RDA (Recommended Dietary Allowances) for. the Japanese was the official data issued by the Japanese Government in 1947, except the temporally issued data during the World War II. After that, the data is still used through several revision. In the meanwhile, the ingested nutrition of the people is rising by the higher the national economy and the only nutrient substance which is still lower than the DA (Dietary Allowance) is Calcium (Ca) today. For this reason, in order to increase the ingestion of Ca, the development of Ca enriched food and the propaganda to increase the consumption of the food which are the supply source of Ca such as Milk and dairy products etc. are made and as the result the ingestion of Calcium is slightly upward tendency. But recently after the report that the death rate of Ischemic Heart Disease (IHD) is increased to correlated with the ratio between Ca and Magnesium (Mg) are published by Karppanen et al. (1978)[1]. The necessity of concerning not only to the ingestion of each minerals but also to make balance of correlated minerals are emphasized by Itokawa [2], Kimura[3] and Suzuki [4] et al; We have no data of ingestion of Mg in the National Nutrition Surveys of Japan which was done once a year from 1946 but following to the data by Itokawa et al., the ingestion of Mg which was surveyed from each stratum in Japan was about 150-250mg and this ingested Mg was only about 1/3- 1/2 compared with 500-600mg of ingestion of Ca. Concerning to the ratio of Ca/Mg, in Japan to keep 2:1 is preferable from the data of Karppanen et al. and RDA for the Japanese of Ca and Mg. Actually, it seems easy but is difficult to keep 2:1 for Ca/Mg by assortment of several food. Fortunately, it is realized to supply the Ca/Mg =2:1 by the utilization of coral which is accumulated in certain area of Okinawa in Japan. This Ca/Mg =2:1 is naturally well-balanced and contains other minute minerals.

Ca/Mg , is this naturally well-balanced minerals comes from Okinawa. By the result of analysis, ordinary coral contains abt. 35% of Ca: and abt.2% of Mg but this special type of coral contains abt. 25% of Ca and abt.10% of. Mg which contents of Mg is higher 'than that of ordinary coral and the ratio of Ca/Mg is closely 2:1. We certified by the data of analysis of both authorized Research Laboratories in Japan and U.S.A.. And usually, ordinary coral sand accumulated on the bottom of the sea sometimes can not use for food-stuff as it contains silica sand but this special coral has not such trouble by the result of analysis.

The Study on Nutrition of Coral Powder

As the several testing results on Coral Powder given to the subjects are reported, I would like to explain about those results.

1. The Influence of Calcium Enriched Food and Exercise upon the Bone Density -I By Prof. Shizue Yamashita et al. (announced and published at Japan Nutrition and Food Society, 1997) .

The influence of Ca enriched food and exercise upon the bone density objected 51 students from 19-32 years of age during 6 months are observed. ' The ingestion of Ca was 1,000mg which was consisted from 400mg by daily foods, 200mg by mill( and 400mg by coral powder. As for exercise, 90 minutes exercise for the purpose of weight control was charged for 1st Group, more than 40 minutes/Day and nearly 140 pulsation exercise was charged 3 times in a week for 2nd Group, 10,000 steps/Day of walking was charged for 3rd Group and exercise was charged for the purpose of weight control as 1st Group but digestion of Ca was not forced to charge for 4th Group. The change of the bone density of 3rd Group was the biggest from 95.4 at the beginning of the test to 96.3 at the end of the test. [6]

2. The Influence of Calcium Enriched Food and Exercise upon the Bone Density -II

By Prof. Shizue Yamashita et al. (announced and published at Japan Nutrition and Food Society, 1998)

The change of bone density by exercise in the case of charging of 600mgIDay of Ca and 300mgIDay of Mg derived from coral powder for one Group and charging of 200ml of mill{ for other Group were objected by 43 of female students from 19-27 years of age.

The object term was 10 months from May 1997 to March 1998 and exercise was divided 2 terms, 1st term was 66 days from May to July and 2nd term was 60 days from October to December. 1st Group was only given Ca enriched food, 2nd and 3rd Group were given enriched food and exercised muscular training and walking. 4th Group was only exercise but divided 2 groups and each group altered muscular training and walking in the middle of objection. The rising of bone density of testing groups was predominantly high, especially that of started from muscular training, Group in the exercise groups (2K Group) was more than that of started from walking Group (2W Group). [7]

3. The Utilization of Calcium derived from Natural Coral Calcium

By Prof. Kazuharu Suzuki et al. (announced and published at Japan Nutrition and Food Society, 1997)

In order to compare the utility efficiency of Ca derived from natural coral powder which contains Ca/Mg at the rate of 2:1, 4 kinds of Ca, Coral Powder, Calcium Carbonate, Milk Calcium and Cow Bone Calcium, are given to 4 month old 30 Wister species rats during 4 weeks. In this case, to keep the amount of Mg controlled with Magnesium Oxide and controlled the ratio of Ca/mg as 2:1. 3 days before the end of feeding, the intake and out put are investigated by the ways of collecting dung and urine. After the feeding, the amount of Ca and Mg were measured from the extracted internal organs and blood serum separately. As the result, the reserved amount of Ca of Coral Powder Group was shown the highest value compared with other Groups. And the rate of the absorption of Ca of this group' in appearance was 69.6%. It was also the highest value compared with other groups. There was no difference between 4 groups about the thickness of Ca and Mg in blood serum, but HDL-the thickness of Cholesterol of Coral Powder was the highest value among 4 groups. As the result, the absorption of Ca of natural Coral Calcium was the better compared with Milk Ca, Cow Bone Ca and Calcium Carbonate. And Natural Coral Calcium seemed to give the favorable result for fat in the blood serum. [8]

4. Calcium Absorption from the ingestion of Coral Derived Calcium by Humans

By Dr. Kunihiko Ishitani et al. (1999 Journal of Nutritional Science Vitamin L 45.509~517)

It is pointed out the defect that the mineral balance in the foods last easily as the chance of ingestion of processed foods were so often recently.

Cookies enriched with well-mineral balanced coral powder and with Calcium Carbonate were given to 12 healthy volunteers (male: 6, female :6) as the cross over design and compared the rate of absorption by the analysis of fecal and urine. As the result of analysis, it was clearly shown, even the numbers of subjects were small, that Ca of Coral Powder was absorbed better than that of Calcium Carbonate. [9]

Conclusion

As the conclusion of above introduced 4 reports, Ca and Mg contained Coral Powder was well absorbed in the human body and it was clear that it contributes for the improvement of bone density.

According to the bar graph shown on the left, only the adults living in fishing villages of isolated islands are reaching Safe and Adequate Daily Dietary Intakes of magnesium. Insufficiency in magnesium is remarkable especially in children in their growth period. (source: Dr Yoshinorl Itokawa, "The course of medical science [Igaku no ayumi] (1990) pp154-213)
