Milk
• All fluid milk
products and
many foods
made from
milk are
considered part
of this food
group.
• But…..
Milk
• Foods made
from milk
that retain
their
calcium
content are
part of the
group.
Milk
• Most milk group choices should be fatfree or low-fat.
Fortified
• Nutrients are added
beyond what the
foods originally
contained.
• Low-fat and non-fat
milk are often
fortified with
vitamin A.
Fat Free Milk vs. Reg. Milk
• DO NOT WRITE…
• Choosing foods from the milk group that are high in
saturated fats and cholesterol can have health
implications. Diets high in saturated fats raise “bad”
cholesterol levels in the blood. The “bad” cholesterol is
called LDL cholesterol. High LDL cholesterol, in turn,
increases the risk for coronary heart disease. Many
cheeses, whole milk, and products made from them are
high in saturated fat. To help keep blood cholesterol
levels healthy, limit the amount of these foods you eat. In
addition, a high intake of fats makes it difficult to avoid
consuming more calories than are needed.
Milk Benefits
• Calcium is used for
building bones and teeth
and in maintaining bone
mass.
• This may reduce the risk
of osteoporosis.
• Vitamin D functions in
the body to maintain
proper levels of calcium.
Daily Recommendation of Milk

poultry, fish,
dry beans or
peas, eggs,
nuts, and seeds

group.
Meat and Beans
• Dry beans and peas are
part of this group as
well as the vegetable
group.
• These foods are
excellent sources of
plant protein, and also
provide other nutrients
such as iron and zinc.
Benefits of Meats and Beans
• Iron is an
important part of
red blood cells,
carries oxygen to
all parts of the
body.
• Zinc helps the
immune system
function

Two Kinds of Proteins
• Complete- a protein that contains all
the essential amino acids.
– Ex: meat, fish, poultry, milk and eggs.
• Incomplete- protein from plant sources
that does not contain all the essential
amino acids.
– Ex: grains, legumes(beans, peas) and
nuts/seeds
Protein
• Each gram of protein provides four
calories of energy.
Amino Acids
• Proteins are made up of chains of amino
acids.
• There are 22 amino acids.
• 8 of these are called the essential amino
acids because they cannot be made by the
body and must be provided by the diet.
Proteins
• Proteins are the building blocks that grow
and repair your body.
• Proteins are needed not only for muscle
but also for hair, skin and internal organs.
Proteins
• Antibodies,
which are made
of protein, help
you resist disease
and infection.
