Lecture Notes:
KIDS AND NUTRITION
-
30% of children are obese.
-
The likelihood of a child who has one obese parent
of becoming obese themselves is 50%.
-
Their likelihood of becoming obese rises to 83% when
they have two obese parents.
Times during a person's life when
fat formation is the highest
-
During the last three months in the womb.
-
During the first year of life.
Bottle fed infants have a tendency to gain more
excess weight than breast fed infants (this is because babies only drink
as much milk from a breast that they need. People who feed with bottle
have a tendency to give the baby the whole bottle, not realizing that they
baby is full.)
-
Adolescence
-
At the time of puberty (about 12 years of age), females
gain a lot of body fat.
-
Females: 25% of total body weight is fat, compared
to males who have only 15% total body weight as fat.
-
This is extremely important because fat cells never
die.
Choosing foods that do not promote
obesity
-
Choose foods that are nutrient dense.
-
Nutrient dense is a term that refers to the nutrient
to calorie ratio in food. You want to choose foods that are high
in nutrient value, but lower in calories.
-
e.g. vegetables are nutrient dense. They have
fiber, vitamin C, vitamin A, and anti-oxidants (which kill harmful chemicals
in the body.)
-
Non nutrient dense foods tend to be high in fat ,
sodium, and calories for a comparably low portion size.
-
Remember: No food is bad food, the important
thing is to watch your portion size.
Iron (Fe) deficiency AKA anemia
-
This is a big problem in America. 60% of school
aged children are at risk for anemia.
-
Fe is in the hemoglobin of red blood cells.
-
Women have a larger problem keeping their Fe requirements
because of blood loss during menstruation.
-
Number one symptom of anemia:
-
Food sources of Fe:
-
red meat is a rich source of Fe (This may be a problem
for children, because of the recent bad media on red meat. If parents
feel that red meat is bad for you, than they will not prepare it for their
children. If children don't eat red meat, they may be at risk for
anemia.) (Vegetarians should look into taking Fe supplements because the
Fe that is in enriched breads, cereals, and vegetables is not easily absorbed
by the body.)
-
Dark meat of turkey and chicken are also rich sources
of Fe.
