Study Notes

Nutritional Needs and Adulthood

Estimated Average Requirement (EAR) is based on the nutrient intake that meets the nutrient need of 50% of the population.
The 97.5th percentile of the distribution is called the Tolerable Upper Intake Level (UL).
An important aspect to consider for staying fit and healthy during adulthood is to maintain a varied diet.
Recommended Dietary Allowances (RDAs) are based on the Estimated Average Requirement (EAR) plus two standard deviations.
Adulthood begins at around 18-20 years of age.

Nutrient Requirements

Women have higher iron requirements compared to men due to menstruation.
Dietary Reference Intakes (DRIs) are used to establish the daily nutrient intake levels of essential nutrients.

Nutrition and Aging

Adults need fewer calories as they age due to decreased physical activity and basal metabolic rate.
Recommended Dietary Allowances (RDAs) estimate the daily nutrient intake level that meets the nutrient need of 97.5% of the population.

Physical Development and Activity

Maximum cardiac output is reached at around 20-30 years of age.
Growth is completed, and people reach their physical peak between 18-25 years of age.
Muscular strength and endurance reach their maximum level between ages twenty and thirty.
Improved cardiovascular endurance is an aspect of physical activity that is improved during adulthood.
Major organs and body systems fully mature at around 25 years of age.
