NUTRITION THROUGH THE LIFE CYCLE 22 NOVEMBER 2010

INFANTS (O-1 YEAR) FACTORS AFFECTING TYPE AND METHOD OF FEEDING RAPID GROWTH RATE greater than at any other time of life MUSCLE CONTROL spoon feeding KIDNEY FUNCTION too much protein and mineral intake (cow’s) milk-tax kidney

INFANTS (O-1 YEAR) FACTORS AFFECTING TYPE AND METHOD OF FEEDING CONTINUED DIGESTIVE ORGANS small stomach and rapid peristalsis -small, frequent feedings DIGESTIVE FUNCTION decreased quantity and quality of pancreatic amylase, lipase and bile limits digestion and absorption- overcome by 4-6 months of age

FACTORS AFFECTING TYPE AND METHOD OF FEEDING CONTINUED IMMUNE SYSTEM INFANTS (O-1 YEAR) FACTORS AFFECTING TYPE AND METHOD OF FEEDING CONTINUED IMMUNE SYSTEM susceptibility to food allergies decreases between 4 and 6 months as immune system matures ERUPTION OF TEETH as ability to chew increases so do the food options    

INFANT FORMULA VS BREAST FEEDING Molecules in Breastmilk INFANTS INFANT FORMULA VS BREAST FEEDING Molecules in Breastmilk Antibodies of secretory IgA class bind to microbes in baby’s digestive tract and thereby prevent them from passing through walls of the gut into body’s tissues.  

INFANTS INFANT FORMULA VS BREAST FEEDING Molecules in Breastmilk Bifidus factor promotes growth of Lactobacillus bifidus, a harmless bacterium, in baby’s gut. Growth of such nonpathogenic bacteria helps to crowd out dangerous varieties

INFANTS INFANT FORMULA VS BREAST FEEDING Molecules in Breastmilk continued Hormones and growth factors stimulate baby’s digestive tract to mature more quickly. Once the initially “leaky” membranes lining the gut mature, infants become less vulnerable to microorganisms.

INFANTS INFANT FORMULA VS BREAST FEEDING Molecules in Breastmilk continued Oligosaccharides Bind to microorganisms and bar them from attaching to mucosal surfaces. Omega 3s in formula

CHILDREN(1-11 YEARS) FACTORS AFFECTING FOOD INTAKE ERRATIC GROWTH GREATER MOBILITY AND COORDINATION SELF FEEDING   AUTONOMY INCREASES EATING WHAT I WANT

EATING HABITS/ATTITUDES PARENTS CHILDREN(1-11 YEARS) FACTORS AFFECTING FOOD INTAKE CONTINUED MUSCLE MASS AND BONE DENSITY INCREASE INCREASED NEED FOR CALCIUM, PHOSPHOROUS AND PROTEIN EATING HABITS/ATTITUDES PARENTS  

CHILDREN(1-11 YEARS) DECREASING PROTEIN, VITAMIN A, C, D, IRON, ZINC AND CALCIUM/KG BODY WEIGHT COMPARED TO INFANTS   BUT NEED MORE TOTAL OF EACH OF THESE NUTRIENTS

FACTORS AFFECTING NUTRITIONAL REQUIREMENTS ADOLESCENTS(12-18 YEARS) FACTORS AFFECTING NUTRITIONAL REQUIREMENTS   RAPID PERIOD OF GROWTH, EMOTIONAL, SOCIAL AND SEXUAL MATURATION INCREASED NEED FOR TOTAL CALORIES, PROTEIN, CALCIUM, IRON AND ZINC RELATIVE TO YOUNGER AGES MENSTRUATION IRON

ADOLESCENTS(12-18 YEARS)CONTINUED FAT DEPOSITION IN PREPARATION FOR CHILD BEARING - FAT REQUIRES LESS ENERGY FOR MAINTENANCE THAN MUSCLE- FEMALES HAVE LOWER CALORIC REQUIREMENT LEAN BODY TISSUE AND BONES IN MALES MALES REQUIRE GREATER NUMBER OF CALORIES AND NEED SAME AMOUNT OF IRON COMPARED TO FEMALES DUE TO MUSCLE AND BLOOD VOLUME INCREASES IN MALES  

ADULTS (19-50) MAINTENANCE AND DISEASE PREVENTION   SENIORS(51-?)

ADULTS CHANGING NUTRITIONAL REQUIREMENTS
