These healthy seeds are cheap, available all over the year and extremely nutritious.
They have high levels of vitamin E, that's why they are very helpful in protecting the heart and the entire cardiovascular system from diseases and various other disorders.
Vitamin E is a very strong antioxidant which combats the presence of free radicals in the body, and so reduces the risk of developing cancer, atherosclerosis, heart attack and stroke.
When the body is low in serotonin, depression, anxiety, tension and stress are common to develop. Serotonin is a type of neurotransmitter and it is processed by what is known as Tryptophan, an amino acid. Sunflower seeds contain Tryptophan, and thus produces serotonin which as said before relieves symptoms of depression, stress, and so on...
Sunflower seeds are also rich in magnesium,which apart from treating conditions like like spasms, and muscle contractions, also helps in lowering risk of hypertension, asthma and migraines.
Last but not least, sunflower seeds improve the whole digestive system due to their rich content in dietary fiber that prevents many kinds of cancer including breast cancer, prostate cancer, colon cancer.
Fiber as you all know also treats constipation, a common condition to everyone 
And finally how many calories is there in sunflower seeds???
Two tablepoon of sunflower seeds contain 45 calories, and these calories come directly from fat... But as I said before from the GOOD FAT 
So don't worry include these healthy seeds in your daily healthy eating habits
