HDLs – LDLs What Does It All Mean?

February 23, 2010

If you are at all conscious about your health you realize that it is very important to have regular physical exams. During this procedure your blood is drawn and then after a day or two you are given information about things like HDL’s and LDL’s.

But what do these numbers represent? What do they mean?

HDL = High Density Lipid

LDL = Low Density Lipid

Know this. HDL is the good lipid and LDL is the bad one.

HDLs actually help sweep away plaque that forms on your arteries. LDLs can’t do this because they are not dense enough to have this effect.

So in other words you want to have a high HDL count and a low LDL count in order to be proactively working against heart disease.

The American Heart Association states that it is desirable for your total cholesterol level to be 200mg/dL or less.

When you break it down you want your HDL level to be in the 40 – 50 mg/dL level for men and 50 – 60 mg/dL level for women. An HDL cholesterol of 60mg/dL or higher gives some protection against heart disease.

LDL cholesterol levels are considered optimal when they are less than 100 mg/dL.

So when should you be checked? The AHA recommends that when you turn 20 you should begin having your blood checked regularly.

As always exercise and diet are your best weapons against a high cholesterol count.

Are Tanning Beds Good For You?

February 9, 2010

Lately I’ve been noticing advertisements for tanning salons claiming that they are a good source of Vitamin D, in other words good for you. I felt this was a bit of a misrepresentation so I decided to do a little research of my own.

As it turns out yes indeed you can receive Vitamin D from tanning beds. However, the risks of skin cancer far out weigh any health benefits you may receive.

In 2009, the International Agency for Research on Cancer (IARC), concluded that tanning devices that emit UV radiation are more dangerous than previously thought. IARC moved these devices into the highest cancer risk category.

IARC’s conclusions and recommendations were based on it’s 2006 review of 19 studies conducted over 25 years on the use of indoor tanning equipment.

The tanning industry would like you to believe that the only way to receive Vitamin D is from UVA and UVB light. When in fact you can get all the Vitamin D you need from dairy, cereal and fish.

I would also like you to know that when I began looking into this the first thing I did was go to Google and search for information concerning Vitamin D and tanning beds. It took me 4 pages of information before I could find research that was not provided by the tanning industry. Apparently this industry has saturated the internet with enough information so that it becomes very difficult to find statistics that are presented by anyone but themselves.
