1 ESSAYS DUE AT 5:35 PM IN CLASS ON 21 NOVEMBER 2013 –NOTHING CLINICAL AND NOTHING RELATING TO PATHOLOGY NO DEFICIENCIES OR TOXICITIES

2 Final exam-120 multiple choice-120 marks from vitamins to end of course -4 short answer questions-15 points each for a total of 60 points covers whole course -3 hours- 180 marks PLEASE SEE EXAM REGULATIONS ON: faculty.cbu.ca/ebarre

3 Beta carotene-fat soluble Lecture 10- 14 November 2013 This lecture is based largely on Chapter 7, 12, 14, 15,16 in Understanding Normal and Clinical Nutrition by Rolfes et al.

4 Lecture 10- 14 November 2013 Outline Water -role in metabolism -role in metabolic regulation

5 Outline of lecture 10 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Infancy Early Childhood Adolescence Adulthood

6 More Detailed Comments Water -role in metabolism -carries nutrients and waste products throughout the body -maintains structure of large molecules like proteins and glycogen

7 Water -role in metabolism -participates in metabolic reactions- eg hydrolysis (eg protein catabolism), or product of metabolism (metabolic sink)(eg when hydrogen joins with oxygen as part of electron transport chain processes) -solvent (provides medium for reactions) -regulation of body temperature -maintains blood volume

8 Water -class exercise -explain each role in metabolic regulation

9 Break

10 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy foetal growth and development -folate supplementation -prevent neural tube defects -one month before conception- why?

11 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy foetal growth and development folate supplementation -0.8 to 4 mg supplements -if have had previous neural tube baby then 4 mg supplements may be recommended - require a prescription as high folate intake may mask pernicious anemia of a vitamin B 12 deficiency

12 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy critical periods -maternal anemia during critical growth period of placental growth alters pattern of blood vessel growth which may affect cardiovascular health of infant

13 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy critical periods -infant beta cell development-poor maternal nutrition during critical period of beta cell development (12 weeks gestation to 5 months post delivery) may cause diabetes particularly if person eats in overabundance in later life

14 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy weight prior to conception-underweight mother -underweight mother leads to greater chance of a low birthweight infant especially if mother is unable to gain sufficient weight during the pregnancy

15 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy weight prior to conception-underweight mother -as well rates of preterm births and infant deaths are higher for underweight women

16 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy weight prior to conception-overweight mother overweight mother leads to greater chance of her experiencing gestational diabetes, hypertension and post-partum infections and of having a stillborn and/or other labour and delivery complications

17 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy weight prior to conception-overweight mother -as well infants tend to be larger and have greater risk of poor health(including neural tube defects) and death than do normal weight infants -never try to lose weight during pregnancy- lose appropriately pre- conception or post-delivery

18 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy weight gain during pregnancy underweight 28-40 lbs correct weight 25-35 lbs overweight 15-25 lbs obese 15 lbs minimum

19 Nutrition metabolism throughout the life cycle Pregnancy and Lactation Pregnancy energy and nutrient needs during pregnancy energy add 100 kcal per day trimester 1 add 300 kcal per trimesters 2 and 3 pregnant teenagers, underweight and physically active women may require more
