Health
benefits of sunflower seeds
-
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.
