Moreover, there may be net losses of some nutrients that occur physiologically regardless of the nutrient intake. For a particular nutrient, average intake by full-term infants who are born to healthy, well-nourished mothers and exclusively fed human milk has been adopted as the primary basis for deriving the AI for most nutrients during the first 6 months of life.

Additional subdivisions within these groups may be added in later reports. After age 70, people of the same Rni malaysia increasingly display variability in physiological functioning and physical activity.

The age group of 9 through 13 years allows for this early growth spurt in females. The mean age of onset of breast development Tanner Stage 2 for white females in the United States is It also supports the recommendation that exclusive breastfeeding is the preferred method of feeding for normal full-term infants for the first 4 to 6 months of life.

One problem encountered in trying to derive intake data in infants was the lack of available data on total nutrient intake from a combination of human milk and solid foods in the second 6 months of life. To derive the AI value for infants ages 0 through 6 months, Rni malaysia malaysia mean intake of a nutrient was calculated based on the average concentration of the nutrient from 2 through Page 33 Share Cite Suggested Citation: Rni malaysia 0 through 6 Months.

For many nutrients, a reasonable amount of data are available on nutrient intake and various criteria for adequacy such as nutrient balance measured in young children aged 5 through 7 years that can be used as the Rni malaysia for the EARs and AIs for this life stage group.

Although they were based on human milk composition and volume of intake, the previous RDA and RNI values allowed for lower bioavailability of nutrients from nonhuman milk.

For some nutrients, the DRIs may be the same for the two age groups. The onset of the growth spurt in girls begins before the onset of breast development Tanner, This approach is in keeping with the current recommendations of the Canadian Paediatric Society Health Canada,the American Academy of Pediatricsand Nutrition During Lactation IOM, for continued breastfeeding of infants through 9 to 12 months of age with appropriate introduction of solid foods.

A comparison of people over age 70 who are the same chronological age may demonstrate as much as a to year, age-related difference in level of reserve capacity and functioning.

Ages 1 through 3 Years The greater velocity of growth in height during ages 1 through 3 compared with ages 4 through 5 provides a biological basis for dividing this period of life. Ages 19 through 30 Years and 31 through 50 Years The recognition of the possible value of higher nutrient intakes during early adulthood to achieving optimal genetic potential for peak bone mass was the reason for dividing adulthood into ages 19 through 30 years and 31 through 50 years.

Ages 9 through 13 Years and 14 through 18 Years Recognizing that current data support younger ages for pubertal development, it was determined that the adolescent age group should begin at 9 years. Thus, to begin the second age category at 14 years and to have different EARs and AIs for females and males for some nutrients at this age seemed biologically appropriate.

Reference Weights and Heights The reference weights and heights selected for adults and children are shown in Table Page 32 Share Cite Suggested Citation: In African American females, onset of breast development is earlier mean 8.

In general, for this report, special consideration was not given to possible variations in physiological need during the first month after birth when, for example, urinary phosphorus loss is lower due to immature glomerular filtration rate [Brodehl et al. Ages 7 through 12 Months.

Ages 4 through 8 Years Because major biological changes in velocity of growth and changing endocrine status occur during ages 4 through 8 or 9 years the latter depending on onset of puberty in each genderthe category of 4 through 8 years is appropriate.

Because of the high variability in functional capacity of older adults, the EARs and AIs for this age group may reflect a greater variability in requirements for the older age categories. Pregnancy and Lactation Recommendations for pregnancy and lactation may be subdivided because of the many physiological changes and changes in nutrient needs that occur during these life stages.

Page 34 Share Cite Suggested Citation: The reasons for the observed racial differences in the age at which girls enter puberty are unknown. In some cases, DRIs were derived from data extrapolated from studies of infants or of children aged 4 years or older.

This may be most applicable to nutrients for which requirements are related to energy expenditure. The value used is thus not an EAR; the extent to which intake of human milk may result in exceeding the actual requirements of the infant is not known, and ethics of experimentation preclude testing the levels known to be potentially inadequate.

The first 6-month interval was not subdivided further because intake is relatively constant during this time. Infancy Infancy covers the period from birth through 12 months of age and is divided into two 6-month intervals.

Young Adulthood and Middle Age: Moreover, mean energy expenditure decreases during this year period, and needs for Page 35 Share Cite Suggested Citation: This is demonstrated by age-related declines in nutrient absorption and renal function.

In setting EARs and AIs for these life stages, however, consideration is given to adaptations to the increased nutrient demand—such as increased absorption and greater conservation of many nutrients.

Adulthood and Older Adults: The National Academies Press. Differences will be indicated by Rni malaysia when warranted by the data. Thus, for some nutrients, there may not be a basis for EAR or AI values that are different during these life stages than they are for other women of comparable age.

Because children in the United States and Canada from age 4 onwards begin to enter the public school system, ending this life stage prior to age 4 seemed appropriate. Therefore, the AI is not an estimated average requirement in which only half of the group would be expected to have their needs met.RNI A Report of the Technical Working Group on Nutritional Guidelines National Coordinating Committee on Food and Nutrition Ministry of Health Malaysia.
