2.     All lipoproteins are made up of proteins, triglycerides, and cholesterol. Why are low-density lipoproteins (LDL) considered unhealthy, and people encouraged to lower LDL, while high-density lipoproteins are considered healthy and people encouraged to increase HDL?

1.     a.     What may happen inside of the cells of an individual who does not obtain all of the essential amino acids?

b.     What may eventually happen to the body’s tissues if the diet does not contain essential amino acids?

3.     How does chronic, excess dietary protein affect the body?

4.   Which foods contain incomplete proteins?

Can someone just eat these foods and get all of the essential amino acids? Why or why not?

5.     Why might a high-protein diet not be the healthiest option for weight loss and weight loss maintenance?

Solution

(2)

LDL particles are referred to as bad cholesterol because they can transport their content of lipid molecules into artery walls, attract macrophages, and cause more incidences of atherosclerosis.

Whereas, HDL lipoproteins are considered healthy cholesterol since they can remove lipid molecules from macrophages in the wall of arteries. Hence decrease the incidences of atherosclerosis.
