Discovery of Vitamin C
Scurvy is a disease
caused by a
deficiency of Vit. C
that has been around
even in Bible days.
It causes bleeding
gums, loss of teeth,
liver spots on the skin
and many other
terrible symptoms.
Untreated it leads to
death.
In olden days many
sailors got scurvy.
It was a real
problem for the
seamen but no one
knew what was
causing it.
In the 1500’s one
ship’s captain
found a
witchdoctor in
Newfoundland that
had a magic potion
of pine needles
that cured his
sailors.

In 1747 a Doctor James Lind thought that
the disease might be caused by the poor
diet the sailors were eating so he tried an
experiment.
He divided some of the sailors into pairs and
added the following things to each pairs
diet.

2 had cider
2 had vinegar
2 had acid, alcohol
ginger and
cinnamon
2 had garlic, mustard
and herbs
2 had seawater
2 had oranges and
lemons
Which sailors were cured?

The 2 sailors that ate the oranges and
lemons were cured of their scurvy.
This proved that something in these
fruits was the cure but they still didn’t
know exactly what it was. From then
on the sailors were fed citrus fruit and
in England became known as
“Limeys”.
How Often Do I Need Vit. C?

Because Vitamin C is water soluble it
is not stored in the body. Any extra
that you eat is discarded from the
body. Therefore, you should eat a
Vitamin C rich food
every day!

Square Watermelons


For those of us who struggle to handle a watermelon because of its size and
shape, help is at hand. Tesco has developed a new square version which
can be sliced like a loaf of bread. The supermarket says many people are
put off the refreshing and healthy fruit because it rolls around in the fridge,
or it is difficult to slice and eat; so they have adopted growing techniques,
which originated in Japan, to offer the square versions.
There is no weird science or genetic modification involved in the process.
They are grown in wooden boxes with clear sides which are placed around
the growing fruit which naturally swells to fill the surrounding shape. The
melons, which feature distinctive dark green and yellow stripes, are being
grown in Brazil by one of Tesco’s regular suppliers and take 60 days to
reach maturity.
Square melons are already available in Japan where they are sold for about
10,000 yen or roughly a sky high £46 [$92USD] appealing only to the
better off as show piece food.
These melons are grown to the exact size so that they fit easily onto the
shelves of 'fridges in Japan.
