The New Wonder Vitamin

The vitamin of the decade has been chosen – Vitamin D. Everyone is taking vitamin D supplements for nearly every health benefit imaginable. It prevents osteoporosis, cancer, aging, flu, colds, heart disease, Parkinson’s Alzheimer’s, multiple sclerosis. You name it, vitamin D can prevent it. This is suspiciously reminiscent of vitamin C in the Linus Pauling era.

So, what do we know about vitamin D? In a nutshell: it is produced by human skin when exposed to sunlight with a UV index of more than 3. It is also found naturally in some foods, notably catfish, salmon, mackerel, sardines, tuna, eggs, beef liver, and for vegans, mushrooms.  Other foods such as milk and cereals are fortified with vitamin D. Severe deficiency causes rickets in children and osteomalacia (soft, easily broken bones) in adults. Severe excess results
in too much calcium in the blood with loss of appetite, nausea, vomiting, and kidney damage.


Too much vitamin D during pregnancy causes mental retardation and facial deformities in the fetus.  Vitamin D is used by nearly every cell in our bodies to regulate everything from calcium levels to immunity. Recent research has shown that too low or too high blood levels of vitamin D are associated with an increase in mortality from all causes. Low levels are strongly associated with
an increase in deaths from heart disease. As with most things, balance is the key: neither too high nor too low.


The evidence for vitamin D as a prevention for cancer deaths is impressive for colorectal cancer, less so for breast cancer and pancreatic cancer. It is clearly essential, along with calcium and other nutrients, in the prevention of osteoporosis. Studies of immunity are more theoretical than real; it does seem to provide some protection from colds and flu in the winter months when sun exposure is insufficient to maintain adequate blood levels. The evidence for
prevention of MS, Parkinson’s and Alzheimer’s is based on inadequate data. Research is in its earliest stages and the randomized controlled trials that will give more definitive answers have not been done yet. Taking large doses of vitamin D for long periods of time without this data, is like offering oneself up as a Guinea pig in an experiment without anyone overseeing the effects.
Do so at your own risk.  


That said how much vitamin D3 (not D2) should you take? The consensus seems to be that the RDA of 200-600IU per day is too low and should be closer to 1,000IU, especially in the winter months. There is no way to know how much you should be taking without a blood test to find out where you are now. If your level is low, ask your doctor how much to take and be sure your blood test is repeated in 3-6 months. If you are pregnant do not take vitamin D without your physician’s okay. And keep watching for the research that will someday tell us the truth about vitamin D.

Our End of Life Letters

Having our life prolonged as long as possible is one thing, but having our death a prolonged event is an altogether different matter. Medical science has the ability to keep our bodies going long after our spirits have departed and our purses are empty. Protection from too much treatment is available to us through what is now called the Advance Directive, previously known as a combination of the Living Will and Durable Power of Attorney for Health Care.

Let's be clear: Advance Directives should not be thought of as legal instruments. Rather, as forms, they provide us the opportunity to state the kind of treatment we would want in our latter days. In the event we are no longer able to make health care decisions, we can name other(s) who know what we want and can act and decide on our behalf. In effect, they are letters to our family and doctors.


It has been shown that hope near life's end is a vital boost to morale, and this hope derives from having some control over events. This is what Advance Directives offer. We have the chance to choose and to limit, often, the treatments available. We can put a brake on the sheer momentum of treatment.


What is most crucial about Advance Directives is, first, they give us a way of thinking about our latter days, and second, provide us with a vehicle to talk to our family and doctor about our views. It is important not only that we make out these forms, but that we distribute them to all who have any voice or concern about our dying.


Then follows the most important element – a conversation with family members who will be involved in those latter days. It is this conversation, the conveyance of our wishes in dialogue form, that enhances the possibility our wishes will be fulfilled at life's end. If those wishes are not being fulfilled in the hospital, families have the ability to call into session the hospital's ethics committee to make clear to all our choices and wishes.


Westminster Cares has the necessary forms available for you. It is best and easiest to fill out these forms in conversation with someone. Westminster Cares can contact Ray Walker, M.D., to be available to answer your questions and help you fill out your Advance Directive. You can choose a place convenient for you. There is no charge for the service.

The Importance of Hydration

Water is essential for a lifetime of optimal health. Approximately 60% of a young adult’s weight is water. As we age this decreases to 50%. Staying hydrated helps us stay healthy as we age.

What else can drinking water or staying hydrated do for us?

  • Moisten the tissues in the eyes, nose, and mouth.
  • Protect the body organs and tissues.
  • Help prevent constipation and dissolve minerals and other nutrients to make them accessible to the body.
  • Regulate body temperature, lubricate joints and lessen the burden on the kidneys and liver by flushing out waste products. Your kidneys do not function properly without adequate water intake.
  • Carry nutrients and oxygen to cells.
Our bodies need water like a car needs oil. If your car doesn't have oil, what happens to the engine? Just like it is important to put the right kind of oil in an engine, we need to put the right kind of water in our bodies as well. It takes a liter of water to flush out a cup of coffee and it takes a gallon to flush a can of soda.

How much water do we need? You should drink one-half your body weight in water (ounces). So if you weigh 130 pounds, you need to drink 65 ounces of water a day, or about eight medium glasses.


During the summer months we tend to drink more water than usual because we sweat a lot. We need to drink extra in hot weather because a lot is lost, but we must remember to drink water all winter long to protect our organs and to keep going strong. Drinking water will also increase your energy by boosting your metabolism. It also facilitates weight loss.


Dehydration in the elderly is common and can be life-threatening. Falls are often a result of the dizziness that results from dehydration. The thirst stimulus decreases with age as does the total water content of our bodies. Seniors should make themselves drink water or non-caffeinated beverages throughout the day. Don’t wait to get thirsty.


Those taking blood pressure medicines or heart medication should talk to their doctors about how much water they should consume per day. As always, one size, or in this case amount, doesn’t fit all.
