These studies on the investigations of real healthy levels in the each age-group by biochemical blood-analysis were performed and have produced conflicting results.
Subjects were men (a teen-ager ninety-ager), a family of age-long standing. Subjects (186 males and 172 females) who tirelessly lived without any change for long years in the same living environment, participated in this investigation.
There were significant different of pattern of change in circulating plasma proteins, plasma urea (nitrogen), total lipids, triglyceride, cholesterol, plasma glucose, etc in the each age-group.
Blood urea (nitrogen), cholesterol, triglyceride, ureic acid levels are estimated an upward trend in accordance with their aging.
An inference of these studies indicated ? if the healthy young age-group (10-20 years old) live under the same living conditions at the present, theirs will be like the healthy levels (conditions) of their parents and grandparents.
It is clear that these investing results are a need for further healthy education in the role of the lifelong education.
