Starshy, sweet, rich in flavor, chestnuts are popular cool-season edible nuts of the northern hemisphere origin. The nuts are native to the hilly forests of China, Japan, Europe, and North America. Botanically, they belong to the beechor Fagaceae family, in the genus: Castenea. Scientific name: Castanea sativa.

Castaneas are very large deciduous trees. They are monoecious, bearing both male and female flowers (“catkins”), in the same tree. They have a remarkable survival history to narrate. Early in the 20th century, the once mighty American-chestnut tree was almost wiped out by pathogenic fungus chestnut blight (Cryphonectria parasitica). A renewed interest has been growing since then to revive native chestnut trees throughout of the USA.

Health benefits of chestnut

Digestive Health

Chestnuts have a high fiber content. Dietary fiber comes in the form of soluble and insoluble. Soluble gets absorbed in water and forms a gel-like consistency in the intestines. This type helps reduce cholesterol and stabilizes blood-sugar levels. Insoluble fiber creates bulk in the stool and helps it pass through the system quickly. This helps reduce the risk for constipation and intestinal complications like diverticulosis -- a condition where small pockets on the intestinal wall lining become inflamed. A 3-ounce serving of roasted chestnuts contains 4 grams of fiber. Nuts have predominately insoluble fiber.

Stable Energy Levels

Most nuts are low in carbohydrates, which is why they often are part of low-carb diet plans. Chestnuts, however, have a high amount of carbs. They contain 45 grams per 3-ounce serving. Carbs are needed for short- and long-term energy, and they help with nervous system function. The carbs that come from chestnuts are complex. Unlike simple carbs, complex carbs are digested slowly, which gives you even energy levels. Simple carbs tend to give you a fast spike of energy followed by a fast dip.

Improved Brain Function

The fat-soluble B vitamins help produce red blood cells, break down protein, carbs and fats for energy, promote healthy skin and enhance brain function. Chestnuts have a generous blend of B vitamins in moderately high amounts. A 3-ounce serving contains 21 percent of the recommended daily value of B-6, 15 percent of folate, 14 percent of thiamine and 9 percent of riboflavin. Eat roasted chestnuts as appetizers with a leafy green salad and lean meat for a vitamin B-packed meal.

Disease Risk Reduction
Chestnuts have a high content of the trace mineral manganese -- an antioxidant, which soaks up free radicals in the system and reduces the risk for cancer and heart disease. According to the University of Maryland Medical Center, manganese also plays a key role in the aging process. A 3-ouce serving of chestnuts contains just over 1 microgram of manganese, which is 50 percent of the recommended daily intake. Manganese also helps with connective-tissue production and blood clotting. Add chopped chestnuts to a bowl of oatmeal for a manganese-packed breakfast.

Stronger Bones
Copper is a trace mineral that enhances bone strength, helps with red blood cell formation and nerve function and boosts the immune system. A trace mineral is only needed in a small amount by the body. Chestnuts contain 22 percent of the recommended daily value of copper per 3-ounce serving. Pair roasted chestnuts with dried prunes for a snack high in copper.
