Chestnuts: Health Benefits and Uses

Chestnuts: Health Benefits and Uses

Summary

Chestnuts are low in fat and high in vitamin C, making them more fruit-like than real nuts. Here's a breakdown of the health benefits and uses of chestnuts.

Chestnuts are low in fat and high in vitamin C, making them more fruit-like than real nuts. They have a spiny shell and a dark brown outer shell that must be removed before eating.

Chestnuts have been a food source for thousands of years. They can be eaten raw, baked, ground into flour, or mixed into pastries. They grow on trees of the chestnut genus, and many species in this group can live an impressive 500 years or more.

There are four main types of chestnut trees: Chinese chestnut, Japanese chestnut, European chestnut, and American chestnut. These trees are native to many places around the world, but before people started transplanting them, they grew in a much smaller area. 

The American chestnut tree was once common in the eastern United States, but in the early 1900s, it was nearly wiped out by a fungal infestation. European chestnuts are the most common and make up most of the chestnuts sold in grocery stores today.

Health benefits

Chestnuts are rich in vitamin C, unique among nuts. In fact, half a cup of raw chestnuts provides you with 35 to 45 percent of your daily vitamin C intake.

If you boil or roast chestnuts, they lose some vitamin C, but this healthy vitamin still makes up 15 to 20 percent of your daily intake. To preserve more vitamin C in chestnuts when cooking, you can roast them at a lower temperature or use a food dehydrator to dry them. 

Chestnuts are still a good source of antioxidants, even after cooking. They're high in gallic acid and ellagic acid - two antioxidants that increase in concentration when cooked. 

Supports heart health

Antioxidants and minerals like magnesium and potassium help reduce the risk of cardiovascular diseases, such as heart disease or stroke. Chestnuts are a good source of these nutrients, which help promote heart health.

Improve digestion

Chestnuts can also help improve your digestion. These nuts are a good source of fiber, which helps keep you regular and supports the growth of healthy bacteria in your gut. Chestnuts are also gluten-free, making them a healthy choice for people with celiac disease.

Blood sugar control

The fiber in chestnuts also helps balance blood sugar. Eating high-fiber foods ensures that your body absorbs starches slowly. This helps avoid spikes in blood sugar, which can be dangerous for people with diabetes. Additionally, chestnuts have a lower glycemic index value of 54. Foods with a lower glycemic index do not cause significant changes in blood sugar levels when you consume them. 

Things to watch out for

For most people, raw chestnuts are safe to eat. However, they do contain tannins, which means they can cause stomach irritation, nausea, or liver damage if you have liver disease or have a lot of kidney problems. 

How to prepare chestnuts?

Look for raw chestnuts at the grocery store from October through December, when they are at their freshest and most nutritious. You can find them in many supermarkets, specialty grocery stores, and farmers' markets. Most chestnuts sold in stores are European chestnuts grown in Italy, but some farmers in the United States also grow them. 

Since raw chestnuts are high in bitter tannins, you may prefer to roast them before serving. This increases their sugar content and adds a hint of sweetness.

Try some of the following ways to cook and eat chestnuts:

Puree chestnuts in a blender and add to hot crepes or pancakes.

Roast chestnuts and use them in place of croutons on salads.

Sprinkle chopped roasted chestnuts over roasted acorns or butternut squash.

To make candied chestnuts – known in France as marron glacé. 

Bake a pound cake with chestnut flour.
