1. Fred Kummerow- a 100-year old scientist/professor who pushed the FDA to  

ban artificial trans fats

2. Triglyceride/Triglycerol- an ester derived from glycerol and three fatty acids;  are the main portion of body fat in humans and other animals, as well as  vegetable fat

3. Hydrogenation- to treat with hydrogen; process commonly used to reduce or  

saturate organic compounds  

4. Trans Fatty Acid- an unsaturated fatty acid that occurs in manufactured  

cooking oils and margarines as a result of the hydrogenation process 5. Cholesterol- a sterol; a type of lipid molecule that is biosynthesized by all  

animal cells because it is an essential structural component of all animal cell  

membranes to maintain structural integrity and fluidity  

6. Omega 3 Fatty Acid- (w-3) polyunsaturated fatty acids with a double bond at  

the third carbon atom from the methyl/omega end of the carbon chain  7. Saturated Fatty Acid- a long chain of carbon atoms all linked together by  

single bonds  

8. Polyunsaturated Fatty Acid- fatty acid chains the contain more than one  

double bond in their backbone  

9. Phospholipid- a lipid containing a phosphate group in its molecule; make up  

the phospholipid bilayer that surrounds cells  

10.Inuit People- diet containing foods that are fished, hunted, mainly fish and fat  to maintain body heat in North America where they live, but are surprisingly  


11.Cis Fatty Acid- two hydrogen atoms are on the same side of a double bond  12.Omega 6 Fatty Acid- (w-6) come from vegetable oil; polyunsaturated fatty  

acids with a double bond at the sixth carbon from the methyl/omega end of  the carbon chain  

1. Amino Acid- chemical units that compose proteins; organic compounds  containing amine, carboxyl group, and a side-chain (R group) specific to each  

amino acid  

2. Limitting Amino Acid- found in the shortest supply during protein synthesis  

from incomplete proteins  

3. Complete Protein- high-quality proteins; contains all of the essential amino  

acids; red meat, poultry, seafood, eggs, and dairy  

4. Incomplete Protein- low-quality protein; contain insufficient amounts of lack  

one or more of the essential amino acids  

5. Essential Amino Acid- cannot be made by the body thus must come from  

food; 9 essential amino acids

a. Non-essential Amino Acid- can be made in the body thus nonessential  in the human diet; 11 nonessential amino acids

6. Complementary Protein- combining two or more foods with incomplete  proteins forms complementary proteins to provide adequate amounts of all  

the essential amino acids  

7. Free Radical- an uncharged molecule having an unpaired balance electron;  

having lost and electron; unstable/reactive

a. diseases and why- they start to steal neighboring electrons attacking  DNA leading to dysfunction, mutation, and cancer, attack enzymes and

proteins disrupting normal cell activities  

∙ atherosclerosis

∙ cancer

∙ inflammatory joint disease

∙ asthma

∙ diabetes

∙ senile dementia

∙ degenerative eye disease  

8. Antioxidant- a substance the inhibits oxidation, especially one used to  counteract the deterioration of stored food products; removes potentially  

damaging oxidizing agents in a living organism  

9. Phytochemical/Phytonutrient- any of various biologically active compounds  found in plants; help protect plants from germs, fungi, bugs, and other  


10.Linus Pauling- American chemist, biochemist, peace activist, author, and  

educator and published papers about the nature of the chemical bond  11. Mega Vitamin Therapy- the use of large doses of vitamins in attempt to
