from fat

2000 – 30% of our calorie intake came
from fat

This is due to the decrease of fat in our
foods today
Past vs. Present

1970 – Studies identified that vitamin A
and D were not being consumed in
sufficient amounts in Canada

Today because of this study we have milk
and margarine that are fortified with
vitamin A and D
Past vs. Present

1970 – Calcium, iron, thiamin, niacin, and
folate intakes were low

Today thiamin and niacin are added to

Calcium, iron, and folate intake still remain
a problem – What does the future hold?

Lifestyle
The most critical factor affecting obesity is
the relationship between activity levels
and calorie intake.
 Calorie intake in today’s world is very high
compared to the amount of activity.

– Technology vs. manpower
– Elevator vs. Stairs
– Car vs. Walking
Why is our caloric intake so high?

Our Decisions

Barriers around us in schools, restaurants,
and society effect our diet. These places
help encourage unhealthy choices.
Our Decisions

It is essentially our choice to:
– Eat what we eat
– And to decide how much we should eat

This being said there are many factors
that affect how we make the decisions
above
Barriers to Healthy Eating

In school
– Availability of less healthy food in cafeterias and
vending machines on school campuses
– Children sell less healthy food (e.g., candy, cookie
dough) to raise funds for important school programs
– Off-campus food venues that offer limited access to
healthy foods and extensive access to less healthy
foods
Barriers to Healthy Eating

In Restaurants
– Large portion sizes and free refills on beverages
– Large number of energy dense, nutrient poor convenience
foods that compete with healthier choices
– Low cost of less healthy foods relative to more nutritious
foods
– Value added meal deals to encourage increased
consumption at little extra cost to the consumer
Barriers to Healthy Eating

In Society
– Easy access to convenience markets that sell predominately less
healthy items
– Easy access and affordability of fast foods and other
prepared/restaurant foods that tend to be high calorie and
nutrient poor.
– Lack of convenient and affordable healthy cooking and nutrition
classes
– Product placement at eye level for children
– Check-out aisles filled with unhealthy foods
Our Society

Pressure from advertising campaigns
spark an interest in food consumption

Oreo Cookies

2 Oreo cookies = 100 kcals/day
How much weight is gained if a person ate
2 Oreo cookies per day for a year and did
not expend the calories?
Oreo Cookies Answer
100 kcals/day
 7 days/week
 100 kcals X 7 days = 700 kcals/week
 700 kcals X 52 weeks = 36400 kcals/year
 36400 kcals / 3500 kcals/lb = 10.4 lbs


You would gain 10.4 lbs each year if you
ate two Oreo cookies per day
