It is during our 20s that we often lay
the foundations for the food habits of our lifetime and
form preferences for what we like to eat. It is important
to consider maintaining physical activity at all periods
of your life as a way of maintaining your body mass. If
you are particularly active your nutritional requirements
will differ from those who lead a more sedentary life.
The recommended daily intakes of vitamins and minerals
listed in the table are an indication of what your body
needs to function. They do not take into consideration
the impact any medical conditions or advice, medication
you may be taking, if you are unwell or recovering from
illness.
During our 20s through to our 40s, nutritional
requirements change mostly for pregnant women. Pregnant
women, in consultation with their doctor's advice, need
to consider increasing their consumption of calcium, iron
and folate rich foods. Folate is important before and in
the early days of pregnancy to in order to avoid the development
of spina bifida in the baby. It is suggested that all women
of childbearing age regularly eat foods containing folate.
Foods containing rich sources of folate
can be found in the table below.
Later on, as women move towards their late
40s some may experience the first signs of menopause. It
is at this time bone loss is accelerated, so women need
to be prepared in order to prevent osteoporosis in later
life. Men too can suffer from osteoporosis and they are
most likely to develop an osteoporosis fracture in their
60s. Both men and women need to maintain their calcium
intake throughout life. This can be achieved by including
low fat dairy foods on a daily basis, undertaking some
weight bearing exercise such as walking, as this can strengthen
bones and help maintain a healthy body weight.
Some of the signs of menopause may be eased
by choosing a high fibre, low fat and low salt diet. For
example, including a variety of plant foods has been found
to reduce many symptoms of menopause, such as hot flushes.
Other good food sources to eat during this time include;
soy products (tofu, soymilk), chickpeas, flax seeds, lentils,
cracked wheat and barley.
