1. KALE
Description
Kale is a remarkable member of
the cruciferous vegetable family known for its ability to thrive during the
cooler seasons of the year and its tendency to grow wild on many different
continents, and especially in countries bordering along the Mediterranean Sea.
The cool-season nature of kale can sometimes be reflected in its flavor. When
exposed to frost, kale can sometimes take on a sweeter taste (that is due to
the conversion of some kale starches into sugars). Overall, however, the taste
of kale can be surprisingly varied, from bitter or peppery to more plain and
slightly sweet.
The three types of kale that we have become familiar with in the produce section of today's grocery stores are actually domesticated versions of wild plants that took farmers hundreds of years to develop. These three types include (1) flatter, wider-leafed kale, (2) darker Lacinato-type kale, and (3) more tightly formed, curly leafed kale. The list below shows some common kale varieties belonging to each of these three types:

(1) Flatter, Wider-Leafed Kale
·
Smooth German
·
Red Russian
·
Beria
·
Black Magic
·
Tronchuda
(2) Darker, Lacinato-Type Kale (also sometimes called Napus or Siberian
type kale)
·
Tuscan Black
·
Dinosaur Kale
·
Toscano
(3) More Tightly Formed, Curly-Leafed Kale (also sometimes called
Scotch or Scotch-curled kale)
·
Dwarf Blue Curled
·
Starbor
·
Darkibor
·
Winterbor
Of course, there are not always
sharp dividing lines between these three types of kale, and you can expect to
find varieties that blend different features. Regardless of variety, however,
all versions of kale are considered cruciferous vegetables and belong to the
Brassica genus of plants that also includes bok choy, broccoli, Brussels
sprouts, cabbage, cauliflower, collards, mustard greens, and turnip greens.
You can find different colors of kale in all three categories described above. However, the most common leaf colors are light to dark green and lavender to dark purple. You'll also find green-leafed kale with purple stems and veins. All of the kales discussed thus far fall into the general category of "culinary kales" that are intended to be eaten. "Ornamental kales" are also edible, but since they have been developed primarily for appearance rather than taste or texture, they may be tougher in texture and harsher in taste.
Unfortunately from a science perspective, there is not always a guaranteed connection between the genus/species/subspecies of kale plant and the looks of the leaves as described above. However, the most common genus/species types of kale are Brassica oleracea and Brassica napus. The most common subspecies (ssp.) and varieties (var.) are:

Along with broccoli, Brussels
sprouts, cabbage, cauliflower, and kohlrabi, you might also hear kale being
referred to as a "cole crop." In general, this term refers to foods
found in the Brassica oleracea genus/species of plant, and it comes
from the Latin word "caulis" meaning "stem."
History
Kale as we know it today was
first cultivated in the Mediterranean region over 2,000 years ago. It played an
important role in the food supply of Europe through the time of the Roman
Empire and during the medieval period in Europe between the 5th and 15th
centuries. European colonizers are believed to have brought the first kale to
North America in the 1600's, and Russian traders are believed to have first
brought this vegetable to Canada a century or so later.
Several thousand farms in the United States grow kale on a commercial basis, primarily in California, Georgia, New Jersey, and Texas. Compared with its fellow cruciferous vegetable, broccoli, total kale acreage is low, and between 5,000-7,500 acres. (For comparison, broccoli acreage is noted to be 130,000-150,000 acres.)

2. Rice
What is rice?
For nearly half the world’s
population, rice is life. Rice provides one of the main sources of calories for
billions of people. It is a staple, a comfort food, a side dish and a main
meal. In fact, rice is so integral to many cultures around the world it is
often intermingled with mythologies, gods and goddesses, ceremonies and
celebrations. It’s also a highly nutritious component of a healthy diet, if you
choose the right source.
How Rice Grows Conventionally
Little rice seedlings are
reverently hand planted in a small backyard paddy in Kyoto, Japan. Space age
technology computers, lasers and airplanes are used to prepare the soil and sow
the rice seeds on mega farms in eastern Texas. Both ways rice will still
miraculously emerge from its meadow-like sea, transforming the dark glassy
surface of the paddy into a shimmering chartreuse blanket. As the seedlings
mature, they draw nutrients from the paddy water. The same water keeps the weed
population under control. Eventually small green flowers take shape and the
wind pollinates the plants. The paddies of rice change from green to golden
yellow to the familiar pale honey color of parched straw.
The levees are opened, the water
is drained and the soil is given time to set. In the United States where the
rice industry is thoroughly mechanized, a giant combine with an air conditioned
cab for the operator, rolls across the field cutting the plants and separating
the rough or paddy rice from the straw. The rough rice is transported to
enormous dryers where the moisture content is reduced. The rice is now ready
for milling. The milling process, although it can be extremely high tech and
efficient, is really very simple. Converted or parboiled rice is steam pressure
treated before it is hulled. The hull is removed in a sheller which is
basically two rubber rollers that remove the hulls by friction. The rice
emerges as brown rice. The bran is removed from the brown rice by abrasion as
the grains are forced to rub against each other. Broken grains are sorted out
as the rice is sifted through a series of screens. In the most sophisticated of
mills a laser scanner spots discolored kernels and almost simultaneously
manages to blast them aside with a stream of pressurized air.
Type of rice:
1. Long Grain
Long-grain rice is about four or
five times as long as it is wide. Typical length varies between 7 to 9
millimeters.
2. Medium Grain
Medium-grain rice is about three
times as long as it is wide, measuring about two millimeters.
3. Short Grain
Short-grain rice is less than
twice as long as it is wide, with fat, round grains that are higher in starch.

3. Wheat
What is wheat?
Wheat is one of the world's most
commonly consumed cereal grains. It comes from a type of grass (Triticum)
that is grown in countless varieties worldwide. Bread wheat, or common
wheat, is the most common species. Several other closely related species
include durum, spelt, emmer, einkorn, and Khorasan wheat.
White and whole wheat flour are
key ingredients in baked goods, such as bread. Other wheat-based foods include
pasta, noodles, semolina, bulgur, and couscous. Wheat is highly
controversial because it contains a protein called gluten, which can trigger a
harmful immune response in predisposed individuals. However, for people
who tolerate it, whole-grain wheat can be a rich source of various
antioxidants, vitamins, minerals, and fibers.
How to storage wheat
Wheat is one of the longest
storing food items around. Whole wheat kernels will store longer and better
than when ground up into flour. When storing your wheat at home, make sure it
is in containers specifically identified on the label as food storage containers.
Round containers are best when storing wheat since wheat gives off heat and
square containers stacked closely together may not allow this heat to escape.
It is important that wheat
doesn’t have a moisture content level higher than 10 percent. A higher moisture
content than this causes damage to the wheat and exposure to oxygen may cause
some forms of bacteria to grow. Storing wheat in a cool, dry place is the
easiest way to keep moisture content low. A properly used oxygen absorber will
also keep exposure to oxygen minimal.
A storage temperature of 40-60° F
results in fresher wheat. However, 60° F and above is still acceptable. Food
storage containers should not be stored directly on a cement floor to prevent
rusting and pest contamination. Wheat should also be stored away from apples,
onions, potatoes, etc., since the odor or flavor may transfer to the wheat.
Nutrition fact
Wheat is packed with vitamins and
minerals. Unfortunately, processing used to produce and refine white flour
removes most of the valuable nutrients. Wheat kernels have three main
divisions; the bran, the endosperm, and the inner embryo or wheat germ. The
bran layer constitutes 14% of the wheat kernel and is removed when producing
white flour. The bran is packed with vitamins A, C, and E, calcium, iron, and
iodine. The bran also happens to be the best source of dietary fiber which aids
in digestion and helps ward off disease. The wheat germ layer is an excellent
source of vitamin E, as well as other vitamins and protein. Many important
nutrients are removed when layers are separated during processing. For this
reason, it makes sense to put whole wheat back into your diet.
Pound for pound, wheat is one of
the least expensive foods available. And, since grain products will expand in
your stomach--satisfying you even if you eat less--using wheat products can
help you stretch your budget by eliminating the need for store-bought,
overpriced, and over-processed goods. If you are concerned that your food
storage may be lacking in protein, a good supply of wheat and beans will form a
complete protein. Just a half cup of uncooked wheat contains 8 to 10 grams of
protein. So, not only will wheat give you the protein needed for muscle growth
and repair, but you will have a low-fat complex carbohydrate to give your body
the energy it needs to make it through the day.
If you still aren’t convinced of
the importance of storing and using wheat, check out our recipe section. As you
begin to use wheat regularly you may be surprised by its versatility, and you
will soon see that wheat really is the staff of life.
