Delicious, nutty, and crunchy sunflower seeds are widely
considered healthful foods. They are high in energy, 100 g
seeds consists of 584 calories. Nonetheless, they are incredible
sources of many health benefiting nutrients, minerals,
antioxidants and vitamins.
-
Much of their calories come from fatty acids. The seeds are
especially rich in poly-unsaturated fatty acid linooleic acid, which comprise more 50% fatty
acids in them. They are also good in mono-unsaturated oleic acid that helps lower
LDL or "bad cholesterol" and
increase HDL or "good cholesterol" in the blood. Research studies
suggest that Mediterranean diet which is rich in mono-unsaturated
fats help to prevent coronary artery disease and stroke by favoring
healthy lipid profile.
-
Like other nuts, they are also very good source of proteins
with fine quality amino acids such as tryptophan that are essential
for growth, especially in children. Just 100 g of seeds provide
about 21 g of protein (37% of daily-recommended values).
-
In addition, the sunflower seeds contain many health
benefiting poly-phenol compounds such as chlorgenic acid, quinic acid, and caffeic
acids. These are natural anti-oxidants which help remove
harmful oxidant molecules from the body. Further, chlorgenic acid
help reduce blood sugar levels by reducing breakdown of glycogen in
the liver.
-
They are indeed very rich source of vitamin E; contain
about 35.17 g per100 g (about 234% of RDA). Vitamin E is a powerful
lipid soluble antioxidant, required for maintaining the integrity
of cell membrane of mucus membranes and skin by protecting it from
harmful oxygen free radicals.
-
Sunflower kernels amongst are one of the finest sources of
B-complex group of vitamins. They are very good sources of
B-complex vitamins such as niacin, folic acid, thiamin (vitamin
B1), pyridoxine (vitamin B6), pantothenic acid, and riboflavin.
-
Sunflowers are incredible sources of folic acid. 100 g of
kernels contains 227 mcg of folic
acid, which is about 37% of recommended daily intake. Folic
acid is essential for DNA synthesis. When given in expectant
mothers during peri-conception period, it may prevent neural tube
defects in the baby.
-
Niacin and pyridoxine
are other B-complex vitamins found abundantly in sunflower
seeds. About 8.35 mg or 52% of daily-required levels of niacin is
provided by just 100 g of seeds. Niacin help reduce LDL-cholesterol
levels in the blood. In addition, it enhances GABA activity inside
the brain, which in turn helps reduce anxiety and neurosis.
-
The seeds are incredibly rich sources of many essential
minerals. Calcium, iron, manganese,
zinc, magnesium, selenium, and copper are especially
concentrated in sunflower. Many of these minerals have vital role
in bone mineralization, red blood cell production, enzyme
synthesis, hormone production, as well as regulation of cardiac and
skeletal muscle activities.
Just a hand full of sunflower kernels a day provides much of the
recommended levels of phenolic anti-oxidants, minerals, vitamins,
and protein.
