Protein
Fat in our Diet
• Stored energy
• Adds tenderness and flavors food
• Makes us feel full
• Transports fat-soluble vitamins
A, D,E & K
• Other functions of fat ?
Fats
• Saturated – Solid at room
temperature, comes from
animals, burns at a higher
temperature, LDL
(Trans-Fat, Hydrogenated Oil)
• Unsaturated – Liquid at
room temperature, come
from plants, burns
at a lower temp. HDL
(Monounsaturated,
Polyunsturated)
Hydrogenated or Partially
Hydrogenated Oil
• In processed foods. Keeps food fresher
longer
• Makes an unsaturated fat act like a
saturated fat
• Hydrogen is forced into the liquid oil
• Has a high burning point so it’s good for
for frying
• Easy to handle, easy to spread and easy
to store

Protein-The Building Blocks
• Body breaks down protein into Amino Acids
• 20 Amino Acids. Your body can make 11
9 Amino Acids can’t be made by the body and
must come from food you eat “Essential Amino
Acids”Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine
Protein must be cooked or breaks down in the
stomach from stomach acid
Essential Amino Acids must be supplied by
your diet. They are not made by your body
Function of Essential Amino Acids
• Contributes Fatty Acids to brain and
nerves
• Promotes normal growth and vision
• Assists in gene regulation
• Maintains outer structure of the skins,
• Helps regulates genetic activities affecting
metabolism
