The nutritional requirements across the lifespan – from pregnancy to childhood, and from adolescence to adulthood








All stages of life development are important in regards to nutrition and should be taken very seriously.  


Pregnancy and nutrional requirements

Research has found that a major new study shows that a pregnant mother's diet not only sensitizes the fetus to those smells and flavors, but physically changes the brain directly impacting what the infant eats and drinks in the future (UCD, 2010).  A diet for pregnant women should consit of all the right quantaties of nutritionally packed foods.  
Before a woman becomes pregnant, she should establish eating habits that will optimally nourish both the growing fetus and herself.  When nutrional values are not met during pregnancy is very likely that chronic disease and low birth weight can become a major factor in an infants future heath(Sizer & Whitney, 2012 p. 491).   Heathly nutritional habits before pregnancy establish the physical readiness for women and aides in the healthy development of the placenta.  According to the guide below a woman should not gain more than 25-35 lbs during her entire pregnancy gaining an excessive amount can cause hypertension and other complications.  In addition, both overweight and obese women have a greater risk of giving birth to infants with heart defects and other abnormalities.


Women who have finacial limitations can get assistance from the Special Supplemental Nutrition Program for Women, Infants, and Chldren know as WIC. These services provide food assistance needs with vouchers or cards to help ensure that women and children are getting the nutritious foods and education needed for healthy growth.
Infants
Good nutrition is essential for the growth and development that occurs during an infant’s first
year of life. The first years infants grow rapidly so it is important that they receive adequate nutrients.  Receiving adequate amounts of nutrition is essential for proper growth.  Positive and supportive feeding attitudes and techniques help infants develop healthy attitudes toward foods. 
Breast milk and infant formula are important sources of lipids, including essential fatty acids,
during infancy. The lipid content of breast milk varies, but after about the first 2 weeks
postpartum, breast milk provides approximately 50 percent of its calories from lipids. 

Even though infants may not be active, they still use a large amount of energy and nutrients.  Formula is an acceptable alternative to breastfeeding, nevertheless, studies have suggested that breastfeeding may offer protection against exssive weight gain later, and could protect against obesity in later life.

When foods are introduced usually at about 4 months  these solid foods provide the needed nutrients that are no longer adequate ly supplied by the breast milk or formula.  This phase should be monitored by the readiness of the infant.  Some children can develop food allergies at this stage so it is important to monitor what they eat to control the allergies.  Below I have provided a video for making homemade baby food from about 9 months of age.
  Children
Children at this stage have many likes and dislikes when it comes to food and introducing new foods can become a struggle, however, allowing them a few preference is ok according to Sizer & Whitney, 2012.  Try introducing foods at the beginning of a meal when they are hungry can work to your advantage.  To provide all the needed nutrients, children’s meals should include a variety of foods from each food group in amounts suited to their appetites and needs. MyPyramid for Preschoolers (2 to 5 years) and MyPyramid for Kids (6 to 11 years), shown in Figure 14-2 (see page 536), demonstrate patterns for planning nutritious meals for children who need 1,200 and 1,800 calories per day. Plenty of physical activity should also be introduced  "Children have become more sedentary, and sedentary shildren are more often overweight" (Sizer, 2012).  Introducing proper nutrition  and physical activity is essential in eliminating obesity in children.

Adolescence

The energy needs of adolescents vary tremendously depending on growth rate, gender, body composition, and physical activity. Energy balance is often diffi cult to regulate in this society—an estimated 15 percent of U.S. children and adolescents 6 to 19 years of age are overweight. On the output side, the spontaneous physical activity of childhood diminishes signifi cantly around
the age of adolescence and, by age 15, slumps far below the recommended levels (Sizer & Whitney, 2012)

 The increase in need for iron during adolescence occurs across the genders, but for different reasons. A boy needs more iron at this time to develop extra lean body mass, whereas a girl needs extra iron not only to gain lean body mass but also to support menstruation. Because menstruation continues throughout a woman’s childbearing years, her need stays high until older age.  This is a crucial time for bone growth. 

Adults

Now that adulthood has come what you do now even at an early age of 20 affects the quality of your life at 60 or 80. According to an old saying, “as the twig is bent, so grows the tree.” Unlike a tree, however, you can bend your own twig in such that if you do not smoke or drink alcoholic beverages you  Those who smoke, drink and and follow a healthy nutritious diet you can add to the longetivity of your life.  Life expectancy in these years are increasing as more and more people are taking charge of their lifestyles and become aware of the choices they make in life.  Fruits and vegetables supply soluble fibers and bioactive food components to helpward off chronic diseases. With aging, however, come problems of transportation,limited cooking facilities, and chewing disabilities that limit some elderly people’s intakes of fresh fruits and vegetables.  Consuming the required fatty acids and fiber intake at this age supports ones good health and helps eliminate constipation.
