Nutrition During life cycle

 

The importance of nutrition throughout the life cycle cannot be refuted. However, the significance of nutrition during specific times of growth, development and aging is becoming increasingly appreciated.

Health professional have recognized for quite some time the effects of nutrition with consider to proper amount of nutrients during pregnancy on the health of infant and mother.

Establishing good dietary habit during childhood lessens the possibility of inappropriate eating behavior later in life.

In adulthood dietary practice aimed at preventing the degenerative disease and disease of aging that develop later in life. During adulthood many changes begin that lead to development of chronic disease, many of these changes can be slowed over the years depending on the quality of the individual’s nutritional intake.

In aging years, the requirements for specific nutrients increases or decrease so proper nutrients intake seems necessary.

 

Energy Requirement (Harris Benedict)

– The estimate energy requirement for girls 9- 18 years:

135.3 – (30.8 x age [yr] + (PA* x 10 x wt [kg]) + (934 x ht[m]) +25

– The estimate energy requirement for boys 9- 18 years:

88.5 – (61.9 x age [yr] + (PA* x 26.7 x wt [kg]) + (903 x ht[m]) +25

– The estimate energy requirement for women:

354 – (6.91 x age [y]) + (PA* x 9.36 x wt [kg]) + 726 x ht [m]

– The estimate energy requirement for men:

662 – (9.53 x age [y]) + (PA* x 15.91 x wt [kg]) + 539.6 x ht [m]
