This type of fat can double the risk of heart disease
What are trans fats?
The 3 major types of lipids found in foods and in the body
What are phospholipids, sterols, and triglycerides?
Fats created as a result of hydrogenation, trans arrangement of carbon atoms around the double bond
What are trans fatty acids?
fat that has spoiled; unpleasant taste and smell

What are saturated fatty acids?
This increases overall blood cholesterol levels and can create inflammation and the formation of plaques in artery walls
What is LDL?
These cannot be synthesized by the body (omega 3 & omega 6)
What are essential fatty acids?
Contain the greatest number of hydrogen atoms possible on the hydrocarbon chain (has no double bonds)
What are saturated fatty acids?
The role of lipoproteins in lipid transportation
What is cholesterol transport?
olive oil, canola oil, peanut oil, avocado
What are monounsaturated fatty acids?
This can increase insulin resistance and the risk of type 2 diabetes
What are trans fats?
reduction reaction in which hydrogen is added to unsaturated fats (oils) under pressure, resulting in solid, shelf-stable fats
What is hydrogenation?

What are omega 6 fatty acids?
This omega # is naturally high enough in our diets
What is omega 6?
This is the hormone released in the intestine to stimulate the release of enzymes used in digestion
What is CCK?
Unsaturated fats containing one double bond
What are monounsaturated fatty acids?
fat molecules grouped together with the hydrophobic ends toward the inside and hydrophilic towards the outside - formed during fat digestion
