Citrus fruits are those that contain citric acid,
hence their characteristic sour taste, and ascorbic acid or vitamin C.
Studies carried on the concentrations present of these two acids in the juice of these
fruits have discovered that the sweeter it is a citrus fruit, the lower the
concentration of citric acid present in its juice is but, on the contrary, the concentration of vitamin C or ascorbic
acid is higher.
That´s why we say that oranges, mandarins, grapefruits,
tangerines are rich in vitamin C because the ones we eat are sweet. And when we
prepare lemonade, we generally add some sugar or honey.
The occasions on which we prepare lemonade or a lemon -based
infusion more often is when we
usually have a cold, or go through a flu process. We do this because citric
acid present in lemon juice is a potent anti-viral and a natural bactericide.
In Portugal it is very typical the consumption of “Carioca
de limão”, an infusion made only with a small piece of lemon peel and served in
a coffee cup. People order the “Carioca de limão” when they feel the symptoms
of a cold or discomfort arisen from
flu processes. And it is that the high concentration of vitamin C in lemon is
found, precisely, in its peel. And, they also drink a “Carioca de limão” when
they feel heartburn or other problems arisen from poor digestion. Citric acid
among its multiple properties stands out for the one of alkalizing.
In summer, when preparing a salad with fresh
vegetables, it is very typical to dress it with lemon juice or vinegar among other
ingredients. Citric acid, in addition to being a powerful germicide, makes easy
the absorption of the minerals present in the vegetables.
Popular wisdom brings us remedies, which we call home
ones. Science, nowadays, demonstrates why these remedies or food combinations
provide us with great therapeutic benefits. And the lemon is a fruit that is
available all year.
