Dietary fiber is important for adolescents. It comes from plant foods and is classified as soluble or insoluble. Soluble fiber lowers cholesterol while insoluble fiber helps prevent constipation. Fiber intake should increase from childhood to adulthood according to age-based guidelines. Meeting fiber needs supports growth, prevents diseases, and balances sugar to protect dental health. However, increasing fiber too quickly can cause discomfort.
2. Diet is defined as the types and amounts of food eaten
daily by an individual [FDI, 1994]
Diet refers to the local action of foods on oral tissues
and encompasses composition of foods, its consistency
and pattern and frequency of eating.
It encompasses the food as it is eaten regardless of its
fate and exerts local/direct effects upon the dentition.

oTypes of Fiber
oTwo types of fibers :
1. Soluble Fiber
2. Insoluble Fiber
Soluble fiber is one that partially dissolves in

According to ”Age +5” rule, dietary fiber intake should
increase from 8 gms. per day at age of 8 yrs to 25 gms. per day
by age 20 years
After 20 years of age, fiber levels of 25-35gms per day are
recommended.
Currently the amount of consumption of dietary fiber among
children is inadequate for optimal health promotion and
disease prevention.
12. Diet in childhood and adolescence influence
not only health of child but also the future
health of adult
Therefore optimal diet during these

dominant flora by increasing bifidobacteria.
These bifidobacteria, which are saccharolytic

25. A sudden increase from low fiber diet to
high fiber diet can create some abdominal
pain, increase flatulence
Also more than 40gms of fiber daily are
linked with decreased absorption of some
important minerals such as Fe, Zn, Ca.
This occurs when fiber binds these
minerals and forms insoluble salts which
are excreted.
