Study Notes

Adulthood

Adulthood is a long period between the active growth and development phases of infancy, childhood, and adolescence, and the older adult phases where a concern is sustaining physical and mental capacity.
Adulthood is subdivided into early adulthood (20s), midlife (40s), and later adulthood (early sixties).

Physiological Changes in Adults

Body composition changes in adults:
Bone loss begins around the 40s
Adiposity: fat redistribution (more central; less subcutaneous)
Increases in hypertension, insulin resistance, and cardiovascular disease
Changes in gut microbiome, releasing nutrients like potassium, B12, biotin, and carnitine

Modifiable Nutritional Risk Factors for Chronic Diseases

Cancer:
Low fruit and vegetable intake
Low antioxidants (vitamins A and C)
High dietary fat intake
Nitrosamines, burnt and charred food
High intakes of pickled and fermented food
Alcohol consumption
High animal-food, low plant-food intake
Heart Disease:
Atherogenic diet
High saturated fat (>10% calories)
Trans-fatty acid intake
Dietary cholesterol intake (>300 mg)
Low fruit and vegetable intake
Low antioxidants
Low intake of whole grains
No or excess alcohol intake
High sodium intake
Low potassium intake
Low intake of milk and dairy foods
High waist circumference (men >40 inches, women >35 inches)
Obesity:
Obesogenic diet
Caloric intake exceeding needs
Unstructured eating
Frequent fast-food consumption
High fat intake
Sugar-sweetened beverage consumption
Energy-dense, low-nutrient food choices
Diabetes:
Atherogenic diet
Obesogenic diet

Nutrients at Risk

Fiber: reduces energy density and weight control
Potassium and Sodium: opposing effects on blood vessels
Calcium and Vitamin D: low vitamin D > less calcium bioavailability
Magnesium: def >> calcium-activated inflammatory cascade
Vitamin A and Vitamin E: antioxidant functions, cell repair
Choline: fatty liver and muscle deterioration, CVD - homocyteine conversion
Iron: Anemia, work performance, cognitive function, immune function

States of Nutritional Health

Resilient and "Healthy": metabolic systems in homeostasis, organs functioning at optimum level
Altered Substrate Availability: early, subclinical state of nutritional harm
Nonspecific Signs and Symptoms: insufficient or excessive intake of nutrients or energy leads to observable changes
Clinical Condition: signs and symptoms of illness, medical diagnosis (e.g., atherosclerosis, osteoporosis, cancer, type 2 diabetes, or depression)
Chronic Condition: altered metabolism and structural changes in tissues become permanent and irreversible
Terminal Illness and Death: final stage in the continuum, complications advance, body systems shut down, and life ceases
