Answer:
Check explanation.
Step-by-step explanation:
LDL and HDL are the acronyms for Low Density Lipoprotein and High Density Lipoprotein respectively. Both are the two main forms of cholesterol.
When someone has a high level of Low Density Lipoprotein (LDL), the values will be 160 and above(between 160 - 189 mg/dL and VERY high level of Low Density Lipoprotein is between 190 upwards) which causes high risk for heart disease and associated disorders.
When someone has a high level of High Density Lipoprotein (HDL), we will be talking of values between 40 - 60 ( in mg/dL) which is good for fighting heart disease and other related disorders. Lower than 40 mg/dL is not good.
==> SUMMARY: High concentration of HDL is good for protection against heart disease and high concentration of LDL is bad fo the protection of the heart against disease and other related diseases.
