How much of the calories consumed by an infant does the brain use at newborn stage?

Which omega-3 fatty acid is NOT mentioned as important for infant brain development?

During which time frame does the brain weight increase by 61%?

What percentage of calories does the brain use at 1 and 2 years old?

What percentage of a boy's brain weight is typically heavier than that of a girl during infancy?

What role do fat stores play in human brain development at birth?

Infant Brain Development

Infant brains are 30% of adult size at birth, and 12.5% of newborn body weight.
By age 30, the brain accounts for just over 2% of body weight.
Boys' brains are typically 7% heavier than girls' during infancy, exceeding the difference explained by body size. This persists throughout life.
Rapid brain growth occurs between birth and age 2.
Brain weight increases by 61% between birth and 6 months.
The brain doubles in weight by one year old
Increases by 33% in the second year of life.
At age 2, the brain reaches 83% of its adult size. This highlights importance of 2-6 years as well.

Infant Brain Energy Needs

The developing infant brain uses 74% of the infant's caloric intake at birth.
At 1 and 2 years, the brain still uses 53% of calories consumed.
Infants have specific nutritional needs compared to adults, due to this high brain energy use.

Omega-3 Fatty Acids

Omega-3 fatty acids (ALA, EPA, and DHA) are crucial for brain development.
Full-term infants have 6 months worth of stored omega-3 fats.
These fats are used to build brain structure and are found in high concentrations in breast milk, aiding brain evolution.
Brain tissue is 60% fat.

This quiz explores the pivotal stages of infant brain development, highlighting growth patterns and energy needs during the early years of life. It also examines the essential role of omega-3 fatty acids in supporting optimal brain function. Understanding these concepts is crucial for ensuring proper nutrition in infants.
