FNL Unit 9
FCS-FNL-7 Student will explain the nutritional requirements of the middle
adult years.
WHY DO WE NEED FATS?Fats are an important energy source
Fats belong to a larger group of compounds called LIPIDS.
Fats are a subgroup of lipids called Triglycerides
FATS CONTINUEDFats are primarily divided into
three different categories – saturated, unsaturated, and trans fat.
All lipids contain fatty acids
FATTY ACIDS Chemical Chains
that contain carbon, hydrogen, and oxygen atoms.
TYPES OF FATTY ACIDS
Saturated Fatty Acids – is fat that is naturally SOLID at room temperature.
Unsaturated Fatty Acids – naturally LIQUID at room temperature.
Trans Fats – Fats which are normally liquid at room temperature, but have been chemically modified to be solid at room temperature through the process of hydrogenation.
ESSENTIAL FATTY ACIDS Necessary fats that humans cannot
synthesize and must be obtained through diet.
EFA’s support the cardiovascular, reproductive, immune and nervous system.
Two Families of EFA:Omega-3Omega-6
CHOLESTEROLA waxy steroid of fat that is
produced in the liver or intestines.
Used to produce hormones and cell membranes and is transported in the blood plasma of all mammals.
