Semolina
Semolina
comes from the endosperm of durum wheat, which contains harder kernels
than those found in other types of wheat. Durum semolina is
particularly valued by pasta makers due to its high protein and gluten
content, which help keep the pasta's shape intact. Durum semolina also
contains more of the antioxidant beta-carotene, responsible for its
golden hue, than other wheat, according to bakery and pastry instructor
Daniel T. DiMuzio, author of the book "Bread Baking: An Artisan's
Perspective." Although semolina itself is not a whole grain, you can
purchase whole-durum semolina, which contains all the nutritionally
relevant parts of the wheat grain. Dr. Mehmet Oz recommends selecting
semolina products that come in a package that says 100 percent
whole-durum semolina.

Whole-Grain Benefits
Whole
grains contain all the essential seed components necessary for optimal
nutrition: the bran, endosperm, or kernel, and the germ. These unrefined
grains provide a rich source of dietary nutrients, including fiber, B
vitamins, iron and magnesium. You can obtain whole grains from foods,
including whole-durum semolina pasta and breads as well as from other
whole-wheat products. In contrast, refined grains, such as white bread,
lose many of their nutritional benefits through the refining process.
The U.S. Department of Agriculture's 2010 Dietary Guidelines for
Americans recommends consuming a minimum of half of all your grains as
whole grains. The whole grains in whole-durum semolina also may decrease
your risk of type 2 diabetes, some cancers and heart disease. In
addition to helping your bowels function properly, the fiber in
whole-semolina pastas and breads may also help you feel fuller longer to
prevent hunger and subsequent overeating. Whole grains also contain
healthy complex carbohydrates and are low in cholesterol and fat.
Immune System Benefits
Plant
pigments, or carotenoids, such as the beta-carotene in semolina, may
help protect your immune system from dangerous pollutants, toxins,
diseases and the damaging effects of the sun's ultraviolet rays.
Research published in the December 1998 edition of the "Journal of the
American College of Nutrition" observed the effects of beta-carotene
supplements on immune system suppression resulting from ultraviolet
light exposure in 32 healthy older men. Subjects were placed in two
groups that received either 30 mg of beta-carotene or a placebo daily
for 47 days. After 28 days, half of each group received 12 ultraviolet
light exposures. Subjects who received both the beta-carotene
supplements and the ultraviolet light sessions exhibited less
immune-system suppression than other participants. Findings suggest that
beta-carotene plays a protective role in the immunosuppressive effects
of ultraviolet light in older male subjects. However, additional
research is needed to scientifically prove the immune-enhancing effects
of consuming semolina pastas and breads.
Protein Benefits
Semolina
is a rich source of protein that generally contains from 12 to 15
percent of this vital nutrient, according to associate professor of
culinary arts and author Paula I. Figoni. Every cell, organ and tissue
in your body contains protein, which is essential to maintaining optimal
cell, muscle and organ function. Complete protein sources from animal
products such as milk, cheese, meat, and eggs contain all the essential
amino acids, or protein-building blocks, your body cannot produce
itself. Likewise, incomplete sources of protein, such as grains and
beans, lack some essential amino acids. However, the abundant protein in
durum semolina, when combined with other protein-rich foods can help
you obtain all the daily protein you need to stay healthy. A 2011 report
from the Centers for Disease Control and Prevention generally
recommends that 10 to 35 percent of your daily calories come from
protein.
