Ageing
is the process by which certain body functions decline gradually with the
passing of time until there may be great impairment (Ensminger, 2005).
According to Eastwood (2007), it is the regression of physiological functions
accompanied by advancing age. The rate of ageing depends upon dietary, genetic
and environmental factors.

Ageing
is not a disease but a normal part of life cycle (Ene-Obong, 2001). The loss of
tissues and organs functioning that accompanies the ageing process takes place
gradually. Generally, scientists believe that the ageing process is genetically
determined but most agree that a lifelong commitment to good eating habit and
adequate exercise can modify health and longevity (Stanfield, 2006).

Ageing
is accompanied by a variety of physiologic, psychologic, economic and social
changes that may comprise nutritional status (Onimawo, 2001). However, there is
considerable difference between individuals regarding these changes. Ideally,
successful ageing include a minimal loss of function. Age related changes occur
in the soft tissues, bone and organ of the body, soft tissue changes include
muscle mass decrease, body fat increase and total body water decrease. Changes
in bone and height include shrinkage in height due to osteoporosis and
inter-vertebral disc flattening, reduce flexibility and declining bone mass.
Organ changes occur in lungs, heart, kidney and liver. The brain also decreases
in weight through a loss of excess circuitry and cells. The effectiveness of
the immune system also declines with age. However, normal ageing involves
changes in these systems (Stanfield, 2006).

According
to Baker (2009), ageing process starts once growth is complete at the age of
25. Later on, the process speeds up and physiological changes become apparent.
The degenerative changes, which accompany ageing include: loss of sensation of
smell and taste, arterial disease, reduction of glucose tolerance, deafness,
failing sight, osteoarthritis, osteoporosis and decline in muscle bulk and
strength. These changes may result to decrease in appetite as well as unpaired
utilizations of nutrients and limitations of function (Lutz, 2007).
