What are LDL & HDL cholesterol?

Lipoproteins. Ldl (low density lipoprotein) and HDL (high density lipoprotein) are types of cholesterol. Ldl is so-called "bad cholesterol" because it increases the risk of heart disease by causing hardening of the arteries/atherosclerosis. Hdl is considered "good cholesterol" since it removes cholesterol from the walls of arteries.
What are LDL and HDL. Ldl stands for low denstiy lipoprotein. Ldl is a particle which carries cholesterol in the blood. When the concentration of LDL particles is elevated, there is more risk of unexpected heart attacks. Hdl is high density lipoprotein. This particle also carries cholesterol. Hdl particles at times, may scoop cholesterol out of blood vessels and bring it to the liver for excretion from the body.
Particles vs. Fats. Ldl (low density lipoprotein) ; HDL (high density lipoprotein) are not cholesterol but complex protein particles which transport all fat molecules in water outside cells. ?ed LDL concentrations ?es incidence of cardiovascular diseases by driving atherosclerosis, thus bad. ?ed HDL considered good because they remove fats from cells which need to get rid of fats, including in the walls of arteries.

Hi my NON-HDL CHOLESTEROL is140 and my ldl is 121. Too abnormal? Thank you

Mildly Elevated. Non-HDL cholesterol is a better predictor of cardiovascular risk than traditional LDL cholesterol measurements. The National Lipid Association (lipids.org),of which I am a founding member, officially published guidelines stating this on September 15th 2014. Lipid levels are one of several cardiac risks factors including high blood pressure,and cigarette smoking that determine cardiac risk. Read more...

Fat in nuts lowers hdl-cholesterol, or the fat in nuts lowers ldl- cholesterol?

Nuts good for HDL. Eating nuts tends to increase HDL (good) cholesterol and decrease LDL (bad) cholesterol. The effect is larger if triglycerides are also elevated. See this excellent review paper for more information: http://www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc3257681 also remember that weight loss and exercise improve cardiovascular risk substantially.

Can you tell me how I could lower my (ldl) cholesterol and raise my (hdl) cholesterol?

Fitness is the key. Medication and perhaps even diet may have an impact, but if it is at all possible, get back into that aerobic fitness lifestyle that you enjoyed so much as a teenager. It will probably not just raise your HDL but protect your heart and brain, and make you feel far better. What a fine gift to give yourself! Read more...

HDL 34, total cholestelrol 160, triglyceroides 75, lp (a) is 5, non HDL cholesterol 131 and LDL 115. How are these numbers?

Not great. Hi. You have good triglycerides and Lp(a). But you have an isolated low HDL (i.e., not associated with hi triglycerides) and a higher than goal LDL. Your non-HDL is actually 126 if your tot. cool. and HDL are correct as stated. Your low HDL is not a treatment target. Do you have a family history of premature atherosclerotic disease? Eat healthily and exercise regularly, and DON'T SMOKE! Good luck! Read more...

Does milk contain LDL or HDL cholesterol?

Neither. It just has cholesterol which the body turns into LDL cholesterol. Read more...
Milk fat. Milk fat contains approximately 65% saturated, 30% monounsaturated, and 5% polyunsaturated fatty acids. Saturated fatty acids are associated with high blood cholesterol; short chain fatty acids are metabolized differently than long chain fatty acids & are not considered to be a factor in heart disease. Conjugated linoleic acid is a trans fatty acid in milkfat that is beneficial to humans —>. Read more...
No. Ldl is a particle that carries cholesterol and triglycerides. It is "bad" because it has the ability to penetrate blood vessels and "dump" cholesterol, thus starting arteriosclerosis. Hdl also carries cholesterol and trigs but it may scoop cholesterol out of blood vessels and is thus "good." milk in large amounts may have an effect on cholesterol but so may other foods and beverages ingested.

Cholesterol 100mg/dl (140-240), HDL cholesterol 37, 5mg/dl (>55), LDL 230ui (135-225), also vit d is 17.Should I worry about cholesterol? I'm treating vit d

Worry re:other risks. First, i presume you mean your chol. Is 230 and LDL 100. The only reason to worry about chol. Is to lower risk of heart disease but your chol. Is not very high and even having normal chol. Does not protect against heart disease. The real cause of heart disease is inflammation.
