When you hear the word ‘chestnut’, what comes to mind? If you’re like most, that’s easy: roasting chestnuts on an open fire. Some of you might even break out into song. Chestnuts are a nut that aren’t often thought about as a food-food, but instead, as a holiday tradition. If you’ve ever eaten chestnuts before, then you may recognize this as a tasty edible nut, but for most people who haven’t, it’s simply a saying they’ve heard about.

But chestnuts are far more than that. In fact, they’re one of the healthiest nuts out there and one that you should be enjoying – not just at the holidays, but at other times during the year as well.

They give off a slightly sweet taste and pack a whole lot of crunch, so perfect for satisfying many of your food cravings.

Let’s take a closer look at the benefits that chestnuts have to offer and then also go over how to roast them and finish off by providing you a few delicious recipes that you can use to prepare them.

Here’s what you should know.

What Are Chestnuts?

Before we address benefits, let’s first consider what these are to begin with. Chestnuts, which go by the scientific name Castanea, come from trees or shrubs that below to the oak and beech tree family.

What’s unique about this nut is that while it is a nut, it’s also considered a fruit. This is because the definition of a fruit is the product of a flowering plant. This holds true for the chestnut, so it can be classified as either.

There are four different types of chestnuts that you can purchase. These include:

American chestnut
Sweet chestnut
Chinese chestnut (not the same as a water chestnut, which is not a nut at all)
Japanese chestnut

When looking at the nutritional profile of chestnuts, we see that they are quite different to many other nuts. Most nuts are low in carbs and high in fat, but chestnuts are the opposite.

This nut is actually a starchy food, so it ranks high on the carbohydrate side of things and low in the fat department. They don’t contain much protein either, so they are a primary carb-dense food. For those on the paleo diet plan for instance, this is actually good news as chestnuts are a permissible food and they are another good source of carbohydrates to eat. Many active people following the paleo diet plan struggle to find good carbohydrate sources for their menu so this is another one they can add to their list.

If you consume 10 chestnuts, you’ll take in about 206 calories, 44.5 grams of carbohydrates, 2.7 grams of protein, 1.8 grams of fat, and 4.3 grams of fiber. On top of that, they’ll also supply you with a good dose of manganese, vitamin C, vitamin B6, copper, folate, thiamine, potassium, riboflavin, phosphorus, vitamin K, magnesium, niacin, pantothenic acid, iron and zinc.

So now that you know a little more about the chestnut, let’s look at some of its many benefits.

Enhanced Digestion

Everyone could use a little digestive support now and then. At least that’s what most of you will be thinking. Digestion problems are all too common and there can be many reasons behind this. Things like too much psychological stress, too much salt in the diet, very few probiotics (or the lack of a quality product such as P3-OM), and not enough sleep can all leave our digestive systems hurting.

The good news is that water chestnuts may help reverse this trend. They help you improve your digestive processes in two different ways.

First, they are high in dietary fiber. Dietary fiber, often referred to as ‘Mother Nature’s broom’ is a way to help clean out your digestive system and ensure that everything is working as it should.

By adding more dietary fiber to your diet plan, you can help push food along through your system, leaving you feeling far better than before. It also helps to relieve constipation and promote more regular bowel movements.

Eating enough dietary fiber in your regular meal plan is a great way to prevent constipation from occurring in the first place.

The second way you’ll benefit from including water chestnuts in your day as far as digestion goes is that they can help to protect the probiotics that are already in your digestive tract (1). So while they may not provide the probiotics themselves, if you are eating probiotic rich food or taking a probiotic product as noted above such as P3-OM, then you will ensure that those probiotics you are consuming are well protected and able to do their job as they should.

Essentially, they provide you extra assurance and support.

Strong Source Of Antioxidants

The next great benefit is that they are also a terrific source of antioxidants. We need to eat more antioxidants in our everyday diet because doing so is what can help us ward off the process of aging.

When you encounter free radicals, either from the environment, from the foods you eat, or from other sources such as stress, your body is suffering oxidative damage. Slowly this damage begins to wear on you, kind of like rust on a car. Unless it’s taken care of, it will eventually cause larger problems to occur. Disease may set in, just as the car may stop running.

Antioxidants provide protection against this. They neutralize the free radicals so they are unable to do harm, thus the aging process does not take place as quickly.

Many people think that fruits and vegetables are the primary sources of antioxidants in the diet and while they are definitely a terrific source, they aren’t the only sources.

Chestnuts can be an excellent source too and help provide the varied nutrition you need to achieve optimal health standing.

Research published in the Bioscience, Biotechnology, and Biochemistry journal (2) has noted that chestnuts appear to be especially powerful at helping combat skin cancer in particular, so if you are someone out in the natural daylight quite often, you’ll definitely want to make sure that you have chestnuts in your meal plan.

Heart Health Benefits

Today, heart disease is currently one of the leading causes of death, with heart disease striking someone in the US about every 43 seconds according to the American Heart Association (3). It only makes sense then that you would want to do everything you can to prevent heart disease from affecting you and the great news is this is a condition that is very controllable.

While genetics will definitely increase your risk factor to a degree, nutrition and lifestyle choices are going to have a larger impact.

The antioxidants that are found in chestnuts also appear to help protect the heart as they can help to reduce the overall levels of inflammation in the body. Additionally, they also contain potassium, which helps to regulate heart beat and rhythm, so getting enough of this into your diet will also be very important for optimal health.

Potassium and sodium intake play a direct role in dictating how blood pressure responds in the body and high blood pressure is one of the leading causes behind heart attacks and strokes.

May Help Ward Off Osteoporosis And Bone Breaks

As you get older, you’ll notice yourself becoming more and more concerned over joint health. While in your 20’s and 30’s, you may have not thought much of it as you felt fine and went about your activities with ease, as your 40’s come on and your 50’s, you may notice achy joints making an appearance. This can put a serious dent in your ability to partake in the physical activities that you enjoy and may even put you at risk of increased bone health issues.

Many people in their older years grow concerned about bone breaks or stress fractures, so doing everything possible to keep your bones in top shape is a must.

The focus tends to be on achieving optimal calcium intake daily to boost bone health, but there are two additional nutrients that are also just as critical: vitamin D and magnesium. Both of these are required in order for the calcium to be used properly to form the bone matrix, so if you are deficient in either of these, you aren’t really doing yourself much good.

Nearly half of all the magnesium in the human body is stored in the bones, so this should give you a pretty good idea of just how important magnesium really is. When vitamin D and magnesium work together, they may help to reduce the risk of bone loss, particularly in women who are going through their menopausal years. During this time, they are at an increased risk of bone density decreases thanks to the shifting hormones that are taking place (4).

Chestnuts are one of the best sources of magnesium that you can consume, however there are other good sources available. These include whole wheat flour, spinach and other dark leafy greens, quinoa, almonds, cashews, black beans, and peanuts. Taking in a combination of these along with your chestnuts will help give you the best protection for your bones.

Cognitive Support 

Want to keep your mind sharp? Then you might just consider taking a serving of chestnuts as a snack during the day. The reason why chestnuts can promote better brain health is because they are a rich source of B vitamins including thiamine, vitamin B6, riboflavin, and folate. When you fall short in any of these B vitamins, you may notice that you are experiencing problems with your cognition including your reaction time and memory.

Furthermore, folate is incredibly important for pregnant women as well as young children to foster proper brain and nervous system development. This makes chestnuts a fantastic food for any woman who is expecting.

If you want to enhance your cognitive health even further, try combining chestnuts with a good Probiotic supplement such as P3-OM, which is proven to enhance brain health.

So as you can see, there are some terrific benefits to chestnuts you don’t want to overlook. They are a very healthy addition to your diet plan.

Roasting Chestnuts

Now let’s get to the classic…roasting chestnuts on an open fire. While this may not be the method you choose to use, roasting chestnuts is not all that challenging.

To start, you’ll want to use a small knife and cut an X into the chestnut. This helps to let steam escape from the chestnut as you roast them. Next, place them on a baking sheet in a single layer and preheat the oven to 425 degrees F. Once the oven is preheated, bake for about 25-30 minutes or until they are a golden brown color. Let cool and then peel and serve.
