Study Notes
Nutrition Fundamentals
- Food is categorized as plants, animals, and fungi. Nutrition is the study of how food impacts health.
- Digestion, absorption, and utilization of nutrients provide bodily energy for daily functions.
- Diet significantly influences the risk of chronic diseases (e.g., heart disease, cancer, diabetes).
- Factors impacting food choices include behavior, social influences, and environmental conditions.
- Health encompasses complete physical, mental, and social well-being, not just the absence of disease.
Macronutrients and Micronutrients
- Macronutrients (fats, carbohydrates, proteins, water) provide energy.
- Micronutrients (vitamins, minerals) support various bodily functions.
- Dietary Reference Intakes (DRIs) are scientifically based values for nutrients.
- DRIs guide nutrition labeling, dietary guidelines, food safety, and counseling programs.
- Estimated Energy Requirement (EER) is the daily caloric intake to maintain energy balance in healthy individuals.
- Recommended Daily Allowance (RDA) is the daily nutrient intake sufficient for nearly all healthy people.
- Tolerable Upper Limit (UL) is the highest possible daily nutrient intake without adverse health risks.
- Estimated Average Requirement (EAR) is the daily intake value for half of the healthy population.
- Daily Value (DV), defined based on a 2,000-calorie diet, helps assess nutrient content in food.
Nutrition Facts Tables
- Food labels must show serving size, calories per serving, and 12 nutrient amounts (grams/milligrams).
- Percent Daily Value (DV %) is included.
- Ingredients are listed by weight, with the heaviest first.
- Flavors, additives, seasonings (except salt), and added vitamins/minerals are listed (if applicable).
Food Security and Insecurity
- Food security exists when all people consistently have physical and economic access to sufficient, safe, and nutritious food.
- Food insecurity is the lack of adequate food availability, accessibility, or quality.
Nutrition Throughout Life Stages
-
Prenatal: Crucial for fertility, sperm quality, and reducing pregnancy complications.
- Pregnancy lasts approximately 40 weeks, divided into three trimesters.
- Energy needs fluctuate during pregnancy (minimal increase in 1st trimester; average increase 340/450 calories per day in 2nd & 3rd, respectively).
- Weight gain is normal and supports fetal and maternal well-being.
- Exercise recommendations are at least 150 minutes per week of moderate-intensity activity.
-
Infancy (0-6 Months): Human milk or infant formula are vital.
- First 1,000 days of life are critical for brain development, requiring higher nutrient intake.
- Infants triple their weight in the first year.
- Breastfeeding babies need a Vitamin D supplement (10 micrograms/400IU) daily.
-
Breastfeeding: Similar nutritional needs as the third trimester of pregnancy, with an increased calorie requirement of 450-500 daily.
-
Infancy (6 months+) and Early Childhood: Transition to complementary feeding (solids) at 6 months of age.
- Focus on diverse flavors and textures.
- Breast milk/formula remains crucial for nutrition.
- Respond to the child's cues to encourage autonomy.
- Monitor growth using growth charts.
-
Toddlers-Adolescence:
- Calorie and nutrient needs vary depending on age and gender.
- Nutrient needs during adolescence support growth spurts, reproductive development and the onset of menstruation in girls.
- Adequate nutrition is essential for overall development and well-being.
-
Older Adults: Increased fiber intake supports digestive health while reducing cancer risk. - Lean protein and healthy fats are important. - Increased calcium, vitamin D, B6, and B12 are usually needed. - Iron requirements may decrease for postmenopausal women.
Feeding Approach
- The Division of Responsibility model guides feeding interactions.
- Parents control what, when, and where children eat.
- Children decide how much and if they eat.
Eating Competence
- Individuals learn internal hunger and satiety cues.
- These cues support choices and prevent obesity.
