How I Get My Winter Vitamin D By
Dr. Al
Sears
The
problem is that even when it’s sunny you might not get enough vitamin
D. In a
study from the city of Calgary – one of the sunniest places in Canada –
almost
every person measured had a vitamin D deficiency – 97 percent of them!1 And
in
Australia, one of the sunniest places on earth, an osteoporosis study
found
over 43 percent of people had low vitamin D levels during the winter.2
And
vitamin D is a mood enhancer, too. Meanwhile,
vitamin D deficiency is linked to osteoporosis (metabolic bone
disease),
increased body fat, unexplained muscle pain, impaired lung function,5 respiratory
infections and
even a depressed sex drive. So
whether sunshine is in short supply (or if you’re simply not getting
enough of
it), how do you ensure you have enough vitamin D? Of course, you can
get it
from eating beef, eggs and even cod liver oil, but my two favorites are: Mushrooms
– Did
you know that mushrooms are the only vegetable in the world
with vitamin D in them? And it almost seems like there are as many
different
types of mushrooms as there are ways to eat them. Here’s
a
list of common mushrooms and their vitamin D levels...

(2010) Alfalfa
–
The herb alfalfa is one of the richest sources of vitamins you
can get from a plant, with high levels of vitamins A, E and K. And
alfalfa
sprouts contain 150 percent more amino acids than corn or wheat. There
are
about 267 IU of vitamin D in each ounce (1.25 cups) of alfalfa leaves.6
You can
eat them raw in a sandwich or salad, or sauté them like spinach. But
I
think the best way to prepare alfalfa leaves is to steam them in a
basket above
boiling water for about five minutes until they’re tender. They make a
great
side dish.
