Its winter time and Christmas time!!! 
What do chestnuts do???
Chestnuts are a good source of dietary fiber, they provide 8 grams per 100 g which is a high content! Fiber diet helps lower blood cholesterol levels by limiting excess cholesterol absorption in the intestines.
Chestnuts contain unsaturated fatty acids and are part of the Mediterranean Diet which is rich in dietary-fiber, healthy fatty acids and antioxidants! This diet prevents coronary artery diseases and strokes by favoring healthy blood lipid profile.
Chestnuts are rich in folates, which is a quite unique feature for nuts and seeds. Adequate consumption of food rich in folates during the peri-conception period helps prevent neural tube defects in the fetus. So Kastana are excellent for pregnant women!:)

Those tasty healthy kind of nuts are extremely high in Potassium which helps in flushing the extra sodium content out of our system! That's what lowers heart rate and blood pressure. They also contain good amount of Magnesium and Phosphorus that are important components of bone metabolism.
I Love Kastana in winter and especially in December Christmas spirit! Roasting them is really my preferred method of cooking, but you can also boil, steam or grill them! Once you've done with that there are many ways to enjoy them. You can dip them with cream cheese, labneh, Ranch or Tabasco sauce.
