Study Notes

Nutritional Considerations (Lifecycle)

Nutritional needs change throughout life stages.
Needs depend on age, physiological conditions, and other factors.

Stages of Life

Pregnancy: Nutritional care starts before conception. Healthy eating is vital during pregnancy to reduce risks for the child, such as chronic diseases. A critical supplement is folate (folic acid supplements).
Post-pregnancy: Meeting needs for lactating mothers. Maternal changes during pregnancy include increased blood volume by 50%, placenta development, and growth of fat and uterus. Weight gain during pregnancy is roughly 25% for the infant and 75% from tissues, fluids, and stores.
Infancy: Covers birth to one year of age.
Toddler: Includes ages 2-3 years, part of early childhood.
Childhood: Covers ages 4-8 years.
Puberty: Includes ages 9-13 years, which is the beginning of adolescence.
Older adolescence, adult, seniors: Includes adults and seniors.

Pregnancy and Nutrition

Eating for two? Pregnant women don't need to eat twice as much, as recommended by Health Canada. It is two to three servings per day.
Macronutrients in pregnancy: Calories needed for the first trimester are similar to those of non-pregnant women. During the second and third trimesters, 2-3 more food servings recommended. Protein increases by ~25g per day, carbohydrate by 45g, and additional 3-5g fibre/day. Essential fatty acids, including long-chain PUFA's (linoleic acid, alpha-linolenic acid, DHA and arachidonic acid) are important during pregnancy.
Micronutrients in pregnancy: Folic acid and vitamin B12 are crucial during pregnancy. Calcium absorption doubles, and vitamin D requirements also double. Iron requirements increase by 50%. Zinc requirements are high, but absorption is affected by high iron intake.

Pregnancy and Exercise

Benefits of moderate exercise during pregnancy (30 minutes per day): Prevents excess weight gain, improves digestion and mood, reduces risk of diabetes and high blood pressure, and speeds up recovery from childbirth. If inactive before pregnancy, a consultation with a physician is recommended.

Common Issues in Pregnancy

Weight gain: A healthy weight gain is 11-16 kg. (25-30 lbs), not highly modifiable.
Morning sickness: Symptoms include dehydration, electrolyte imbalance, and weight loss.
Adolescent pregnancy: Nutrient needs are higher due to physical and developmental needs. Socio-economic issues affect the development.
Gestational diabetes: High risk of childhood obesity.

Birth Weight

Low BW (< 2.5 kg or 5.5 lbs): Birth complications, defects, diseases, and death.
Normal BW (3-4 kg or 6.5-9 lbs).
High BW (> 4 kg or 9 lbs): Difficult birth, complications for both mother and child, and potential infection.

Canadian Recommendations for Baby

Exclusive breastfeeding for the first six months, unless exceptions apply (e.g., iron-fortified infant formula).
All breastfed infants need a vitamin D supplement of 400IU.
Breastfeeding should be continued as long as breastfeeding continues.

A Healthy Baby

Birthweight doubles in 4 months and triples in one year.
Energy needs for first year: ~100kcal/kg/day.
6 months - basal metabolic rate is very high
7-12 months - basal metabolic rate decreases as activity starts.
Measuring growth: Height, weight, head circumference should be tracked against standards to monitor proper growth.

Mom's Nutritional Requirements while Breastfeeding

Fluid: Milk production requires 750 ml-1L of milk production daily. Water intake should be at least 1L more than pre-pregnancy.
Energy: Milk production needs ~700-800 Kcal daily, and around 500 kcal + previous pregnancy intake is recommended.
Weight loss: 200kcal/day deficit (or less).

Baby's First Foods

6 months: Continue breastfeeding, offer iron-fortified foods (e.g., meat, fish, poultry, tofu, legumes, egg white).
6-8 months: Gradually increase the number of complementary foods offered daily. Offer finger foods, infant breads, and crackers/biscuits.
9 months: Offer breads, cereals, soft-cooked vegetables, fruits, and juices, in addition to the previous foods.
10-12 months: Introduce a variety of foods, increasing texture gradually, continue to breastfeed or use iron-fortified formula as necessary. Limit cow's whole milk to a maximum of 750 ml/day.

Geriatric Nutrition

Diet & exercise to maintain muscle mass (fat mass increases with age).
Good nutrition is key for healthy, active, healthy life expectancy.
Maintaining a healthy lifestyle.

Geriatric Nutrition (Older Adults)

Lowered Basal Metabolic Rate (BMR), Lowered Lean Body Mass (LBM): Energy needs are lower in older adults.
Micronutrient needs stay the same or may increase in certain cases (Vit D, B12, folate, calcium, and iron are essential).
Fluid needs stay the same, but risks of dehydration increase—especially due to multiple medications.
Higher risk of malnutrition/undernutrition and sarcopenic obesity.
Physiological changes due to aging impacting body composition, mobility, risk of falls, and acute/chronic health issues. (kidney disease, blood pressure and heart disease)

Nutritional Considerations in the Elderly

Physical changes (reduced muscle mass, reduced activity, aging).
Difficulty accessing or preparing food
Loneliness; low income
Confusion, depression
Poor appetite
Alcohol use/abuse
Institutionalization

Geriatric Nutrition cont'd

Maintain an active lifestyle and involvement in the community.
Support individualized care.
Nutrition issues are complex.
Respect dignity and quality of life.
