Health
benefits of strawberries
-
Strawberry is low in
calories (32 kcal/100g) and fats but rich
source of many health promoting phyto-nutrients, minerals and vitamins
that are essential for optimum health.
-
Strawberries have
significantly high amounts of phenolic flavonoid phyto-chemicals called
anthocyanins
and ellagic acid.
Scientific studies show that consumption
of straw berries may have potential health benefits against cancer,
aging, inflammation and neurological diseases.
-
Fresh berries are an
excellent
source of vitamin-C
(about 98% of RDI), which is also a powerful
natural antioxidant. Consumption of fruits rich in vitamin C helps body
develop resistance against infectious agents, counter inflammation and
scavenge harmful free radicals.
-
The fruit is rich in
B-complex
group of vitamins. It contains very good amounts of vitamin B-6,
niacin, riboflavin, pantothenic acid and folic acid. These vitamins are
acting as co-factors help body metabolize carbohydrates, proteins and
fats.
-
Strawberries contain
vitamin
A, vitamin E and many health promoting flavonoid poly phenolic
antioxidants such as lutein, zeaxanthin, beta carotene in small
amounts. These compounds help act as protective scavengers against
oxygen-derived free radicals and reactive oxygen species (ROS) that
play a role in aging and various disease process.
-
They contain good
amount
of minerals like potassium, manganese, fluorine, copper, iron and
iodine. Potassium in an important component of cell and body fluids
that helps controlling heart rate and blood pressure. Manganese is used
by the body as a co-factor for the antioxidant enzyme superoxide
dismutase. Copper is required in the production of red
blood cells.
Iron is required for red blood cell formation. Fluoride is a component
of bones and teeth and is important for prevention of dental caries.

Selection
and storage
Strawberries
are usually
available year round in the stores but are
fresh and plentiful from the spring through the mid-summer. Although
wild varieties are sometimes available in the market, large scale
production uses the modern "plasticulture" system. In this method,
raised beds are formed each year, fumigated, and covered with plastic,
which prevents weed growth and soiling of berries.
In the store,
select berries that are shiny, deep red in color with
attached green caps, firm, plump, free of sand and mold. Avoid berries
that appear dull, sunken or flattened and those with signs of mold,
cuts or discolored patches on the surface. Unripe ones have green or
yellow patches on their surface; and since they stop ripening soon
after harvested, they should be avoided as they
are likely to be sour in taste and are of inferior in quality. These
berries are
easily
perishable; and therefore should only be purchased a few days prior to
use.
Before storing
in the refrigerator, remove any berries that
got
mold or damaged so that they should not spoil others. Place them in a
wide bowl or spread out on a plate covered with paper towel,
then cover with plastic wrap. They keep fresh in the refrigerator for a
day or two. Use them as early as possible unless otherwise they
are
frozen and stored in the freezer compartment.
Preparation
and serving tips
To wash
strawberries, dip them
in cold water in a large bowl for few
seconds and swish gently few times. This method help remove any sand
and
insecticide/fungicide
residues. Then ,gently pat them dry using paper towel or cloth. This
method
also helps bring them to room temperature, increase their
flavor and
enriches taste. Then remove the stems and caps by simply pinching off
with your fingers or using a paring knife.
Here are some serving tips:
- Sliced fresh straw-berries can be a great
addition to fruit or green salad.
- Straw-berries can be a great snack between
meals. Dried strawberry slices are used cereal flakes as a breakfast
recipe.
- The berries are a popular addition to dairy
products, as in strawberry flavored ice cream, milkshakes, smoothies
and yogurts. Strawberry pie is also very popular.
