Revealing MyPyramid
and the Athlete

Overview
• MyPyramid
• The Food Groups
• The health benefits of
consuming each
group
• How well does the
tool support sport
nutrition
• Conclusions
What is MyPyramid?
• It is the 21st century
Food Guide tool for
Americans
• It was released by the
United States
Department of
Agriculture in 2005
• Visit mypyramid.gov
What is MyPyramid?
• The MyPyramid is a personalized diet
plan based on age, gender body weight
and activity.
• There is Calorie Control provided to
achieve a healthy body weight.
• It is web-based, easy to use and
provides loads of nutrition information.
What is MyPyramid?
• It encourages the consumption of whole
grains, a variety of vegetables, fruits, fatfree or low-fat milk or milk alternatives,
low fat meat and beans, and healthy
plant oils.
• It discourages the excessive intakes of
sugar and solid fats, as well as a
sedentary lifestyle.
What are the Food Groups?
•
•
•
•
•
•
•
Grains
Vegetables
Fruits
Oils
Milk
Meat and Beans
[Discretionary Calories]
Grains
Make ½ whole grain
represented by the Orange area
• Health Benefits:
Grains reduce heart
disease, neural tube
defects during fetal
development, and
both constipation
and obesity when
eaten as whole
grains.
Vegetables
include those high in vitamin C & A
represented by the Green area
• Health Benefits:
Vegetables reduce
cardiovascular disease,
heart disease, stroke,
type 2 diabetes, some
cancers, kidney stones,
and bone loss. Eating
vegetables that are low in
calories instead of highercalorie foods may be
useful in helping to lower
Calorie intake.
Vegetables
include those high in vitamin C & A
represented by the Green area
•

•
•
•
Subgroups:
Dark green
orange
legumes
starchy
other
Fruit
include those high in vitamin C & A
represented by the Red area
• Health Benefits:
Fruits reduce
cardiovascular
disease, heart
disease, stroke, type
2 diabetes, some
cancers, kidney
stones, and bone
loss.
Milk
chose fat-free or low-fat
represented by the Blue area
• Health Benefits:
Milk products
reduce the risk of
low bone mass
throughout the life
cycle and may
prevent
osteoporosis.
Meat & Beans
choose lean or low-fat
represented by the Purple area
• Health Implications:
Foods in the meat and
beans group provide
nutrients that are vital for
health and body
maintenance. However,
choosing foods from this
group that are high in
saturated fat and
cholesterol may increase
the risk for heart disease.
Oils
Healthy fats
represented by the Yellow area
• Health Benefits:
Oils are essential
for cardiovascular
health.
• Health
Implications: The
intake of too much
increases
inflammation and
cancer risk.
Discretionary Calories (DC)
• Is a allocated amount of Calories from
Hazardous Biological Molecules that
decrease nutrient density in the diet!
• DCs are calories from solid fats and added
sugars.
• For every gram of sugar count 4 Calories.
• For every gram of fat count 9 Calories.
Discretionary Calories
• Solid fats: Solid fats are solid at room temperature,
like butter and shortening. Solid fats come from
many animal foods, can be made from vegetable oils
through hydrogenation, and are found naturally in
coconut and palm plant foods.
• Common solid fats are: Butter, shortening, stick
margarine, and beef, chicken, and pork fat.
• Foods high in solid fats include: many cheeses,
creams, ice creams, well-marbled cuts of meats,
regular ground beef, bacon, sausages, poultry skin,
many baked goods (such as cookies, crackers,
donuts, pastries, and croissants).
Discretionary Calories
• Added Sugars: Added sugars are sugars and syrups
that are added to foods or beverages during processing
or preparation. This does not include naturally occurring
sugars such as those that occur in milk and fruits.
• Ingredients shown on food labels of processed foods
indicate added sugar: brown sugar, corn sweetener,
corn syrup, dextrose, fructose, fruit juice concentrates,
glucose, high-fructose corn syrup, honey, invert sugar,
lactose, maltose, malt syrup, molasses, raw sugar,
sucrose, sugar, and syrup
Discretionary Calories
• The Allowance amounts of the DC in a food
intake pattern after accounting for the
Calories needed for all food groups—using
forms of foods that are fat-free or low-fat and
with very little added sugars.
• The discretionary Calorie allowance is small:
Most adults will not be in compliance
consuming 1 can of coke and a medium order
of fries, as we will see.
Back to the Question?
• How well does the MyPyramid
recommendations support the athlete's
nutritional needs?
• The research selected four groups to
evaluate: Female and Male groups of 17
years old and 22 years old with
• Female weight groups 120, 140 and 160
• Male weight groups 150, 170, 190
Research Method
• Using the MyPyramid.gov site, the calorie
levels for each group of athletes was
determined
• The MyPyramid food pattern was used to
perform diet analyses using the ESHA Diet
Analyses plus software version 8.0.
• Then sports nutrition recommendations
were used to interpret the diet analysis for
nutritional adequacy.

Needed Adjustments
• By reducing total fat intake by 10 % of total
calories, and
• Increasing CHO intake by 10% of total
calories
• which is recommended as a sporty diet,
• grams of CHO per kg bwt was put into a
better range.
• This results in the following dietary
changes:

In Conclusion
• MyPyramid recommends a high protein,
moderate CHO and fat diet.
• To support more rigorous activity, more
carbohydrate and less fat would be
recommended.
• Protein rich foods and oils needed to be
reduced and grains and fruits needed to
be increased.
In Conclusion
• Athletes need to
consult a dietitian to
be prescribed the
optimal diet to support
their performance.
• There is not a public
sector tool available
to support the athlete.
