When I
was in my twenties and thirties I used to get lots of bruises on my arms and
legs. I started reading about what might
be causing these and learned that smoking, stress, and drinking alcohol (yes,
yes, and yes) can all deplete vitamin C.
I started taking a vitamin C supplement and there was less bruising. This experience caused me to pay
more attention to nutrition.
In those
days I would sometimes visit my parents and notice how little they were eating;
such a meager diet, I thought, couldn’t possibly provide all the nutrients they
needed. I suggested to my father that
they take a multivitamin. My father
refused, saying his doctor had told him that a balanced diet provides all the
nutrients a person needs. Taking
supplements, the doctor said, just produces expensive urine. I believe that my parents’ final illnesses
were both worsened by malnutrition.
Even
after decades of research showing that vitamin deficiencies are common and that
balanced diets are the exception rather than the rule, some doctors are still
repeating this wrong-headed advice. For
these individuals, “The Nutrition Source,” which
is part of the web site of the Harvard School of Public Health, should be required
reading. It provides clear, sensible
guidance based on the latest research.
The article on vitamin D is especially valuable. Inadequate levels of this nutrient are
common, especially among dark-skinned people, the elderly, and those who live
in cold climates. Recent research has
related vitamin D deficiency to a long list of serious illnesses from heart
disease and cancer to depression.
How can
I tell whether I am getting enough of a particular nutrient in my diet? I ask
my doctor to order a blood test. When
the results arrive, I ask for a copy and read it carefully. Usually there will be a range of values that
are considered normal next to the actual value from your own blood sample. If my level is below the normal range, even
by a little bit, I talk to my doctor about taking a supplement. When it comes to test results, doctors tend
to focus on numbers that are strong predictors of disease, such as high triglycerides
or LDL (bad cholesterol). A slightly low
protein level may not even be addressed because it seems to pose no immediate
threat. In the long run, though, minor
deficiencies may have a significant impact on the person’s health. In my case, taking a protein supplement has
helped to develop stronger muscles and to improve my overall fitness.
