Why is cholesterol important for your health and the function of your body?

Q. Why is cholesterol important for your health and the function of your body? Is cholesterol in your diet really that bad?

A. Cholesterol doesn't make you fat or anything, but it contributes to heart disease in the future. If you have a high cholesterol, you have a high chance of heart disease. To prevent this, try eating mono-unsaturated fats, and poly-unsaturated fats. These are good fats that lower bad cholesterol, and increase your good cholesterol. Sources of mono and poly unsaturated fats are nuts - almonds, pecans, peanuts, and walnuts, and cooking oil, lol.

How much cholesterol should the average person allow in their diet a day?
Q. Also my Cholesterol is 225, does that mean I should have less than the average person? How much is the right amount?
They did not tell me what my good cholesterol vs my bad cholesterol is but im concerned with how much intake I should allow.

A. Hi MaggieMay,

Itâs currently recommended, for individuals with normal cholesterol levels, to limit dietary cholesterol intake to 300 mg or less daily. If you have high LDL cholesterol, the current recommendations are to limit dietary cholesterol to 200 mg or less per day.

All the best,

How is cholesterol calculated and can you have too much good cholesterol?
Q. I went to the doctor and my cholesterol was 246 which isn't so good but my good cholesterol was 65, which she said is great. Is the LDL what's remaining after the good cholesterol is subtracted from the total? Can you have too much HDL?

A. HDL are "high-density lipoproteins" which is fancy doctor talk for cells that are high in protein, low in fat/cholesterol. This is preferred, as this is what "feeds" the body with growth proteins. Proteins power "cell" creation and repair (only). Things like muscle, skin, hair, etc...anything that grows or requires frequent repair benefit from higher counts of HDL. HDL's increase in demand with more activity. Specifically 'cardio' (meaning heart) workouts. You really can't have "too much" HDL's because if the body doesnt need the level of proteins in the blood sugar, it simply release it as it passes through the kidneys. We pee out excess proteins. They do NOT convert to bodyfat like some bodybuilders like to beleive.

LDLs are of course "Low density", meaning low protein high fat. LDL's partially provide energy to "active" muscles. The cells are often "coated" with saturated fats. As these move around the body feeding active muscles, they 'bump along' the artery walls, the leave little "skid marks" so to speak. These marks build up to become plaque, and can cause heart decrease. Reducing LDL's to under 200, (or 150 even better) would be good advice but often requires medication, diet modification, AND more physical activity.
