Chestnuts are edible nuts produced by the trees and shrubs of the Castanea genus, which are commonly found throughout the northern hemisphere. While there are a number of different species of chestnuts, most of them possess similar qualities and nutritional profiles. They should not be confused with horse chestnuts, which are quite different. There are a number of ways in which chestnut trees are used to get health benefits, although the fruit of the tree (the chestnut itself) is arguably the most popular.
Many people are unaware of the significant role that dietary fiber can play in the regulation, prevention, and management of diabetes. Foods that are high in dietary fiber, like chestnuts, are considered a low glycemic food, which means that they cause blood sugar to rise slowly as compared to high glycemic foods. This helps prevent the spikes and drops in blood sugar that can be dangerous for diabetic patients, and are often precursors to the development of diabetes in those currently unaffected.
The high concentration of vitamin C and other antioxidant compounds in chestnuts make them an ideal boost to your immune system. Vitamin C not only stimulates the production of white blood cells but also acts as an antioxidant, seeking out free radicals within the body and neutralizing them before they cause healthy cells to mutate or induce oxidative stress near vital organs. This can help the immune system focus its efforts on pathogens and preventing illnesses.
Copper and magnesium aren’t the first things that one thinks of when it comes to bone health, but copper is extremely important in the process by which the body absorbs iron, which is also crucial for bone growth and development. Magnesium is very good for increasing bone mineral density and provides a wide variety of other health benefits. With these vital minerals that are found in chestnuts, you can prevent or slow the onset of many age-related disorders, such as osteoporosis.
Chestnuts have one of the highest content of dietary fiber in the world of “nuts”, which means that they are powerful allies in any gastrointestinal struggle. Dietary fiber helps stimulate peristaltic motion in the intestines, thus regulating your bowel movements and preventing inflammation and discomfort. Dietary fiber can also help optimize the absorption of nutrients, which means getting more out of the food you eat and a better overall nutrient profile.
Brain function and cognition are improved in a number of ways through the consumption of chestnuts. First of all, these nuts are rich in the B family vitamins (e.g., folate, riboflavin, thiamine) which are directly linked to proper neurological development and function. Furthermore, the potassium found in chestnuts can increase blood flow to the brain and promote good nervous system health, thus increasing concentration, retention, and memory.
Chronic illnesses of all kinds are caused by the release of free radicals, the natural byproducts of cellular respiration. These can cause healthy cells to mutate, resulting in cancer, oxidative stress and a number of chronic illnesses. Without antioxidants, like those found in chestnuts, our body would be fighting battles on many fronts, so increasing your defenses with a handful of chestnuts a day is a good idea.
When it comes to lowering blood pressure, few minerals are as essential as potassium. Potassium controls water movement within the body, and also functions as a vasodilator, increasing blood flow and releasing the tension on constricted blood vessels and arteries. This reduction in blood pressure can boost overall cardiovascular health and lessen your risk of heart attacks and strokes.
Many people think of fats as a bad thing, which is to be burned off during a diet, but in reality, our body needs a number of other fats to function normally. These good fats, found in high concentrations in chestnuts, help to balance cholesterol, reduce inflammation throughout the body, and lower the risk of atherosclerosis and blood clots building up in the body. All of this lowers the risk of stroke, heart attack, and coronary heart diseases to a greater extent.
