Hazelnuts are a delicious nut, with a sweet and nutty flavor that is loved by many. They are an important ingredient in many sweet and savory dishes, and can also be enjoyed as a healthy and nutritious snack. Hazelnuts have a rich nutritional profile and are packed with vitamins, minerals, healthy fats and protein.
Nutritional Benefits of Hazelnuts
Hazelnuts are an excellent source of essential minerals. They are particularly high in magnesium, phosphorus, and potassium. Magnesium helps to regulate blood pressure, and both phosphorus and potassium are important for strong bones and teeth. Hazelnuts also contain a good amount of selenium, an important antioxidant. Selenium helps the body to fight against oxidative damage and may help to reduce the risk of certain illnesses, such as cancer and heart disease.
Hazelnuts are a rich source of protein, providing 6 grams of protein per one-ounce serving. This makes them a great option for those who are looking to increase their protein intake. Hazelnuts are also a great source of dietary fiber, providing 3 grams per one-ounce serving. Fiber helps to promote regularity and may help to reduce the risk of certain illnesses, such as type 2 diabetes.
Hazelnuts are also a great source of healthy fats. They contain both monounsaturated and polyunsaturated fats, both of which are considered “good” fats. Monounsaturated fats help to reduce bad cholesterol and help to promote heart health. Polyunsaturated fats are also essential for maintaining a healthy heart and can help to reduce inflammation. Hazelnuts also contain omega-3 fatty acids, which are essential for brain health.
Hazelnuts are also loaded with antioxidants. Antioxidants help to neutralize free radicals and protect our cells from oxidative damage. Hazelnuts contain a variety of antioxidants, including vitamin E, selenium, and phenolic compounds. These compounds can help to reduce the risk of certain illnesses, such as cancer, heart disease, and stroke.
History of Hazelnuts
Hazelnuts are a type of nut native to Europe, Asia, and Northern Africa and have a long and fascinating history. They have been a part of the human diet since the Bronze Age, with evidence of their consumption dating back as far as 4000 BC. The hazel tree has been an important part of the human landscape for centuries, providing not only food but also a valuable source of wood for fuel, cooking, and crafts.
The ancient Greeks were the first to cultivate hazelnuts, using them for medicinal purposes and as a food staple. In the middle ages, monks were responsible for propagating and cultivating different varieties of hazelnuts. It was during this period that hazelnuts became popular in Europe as a snack or ingredient in recipes. By the 15th century, hazelnuts were widely traded and used as a form of currency.
During the 16th and 17th centuries, hazelnuts were used in both sweet and savory recipes. They were used to make a variety of confections, such as hazelnut brittle and hazelnut nougat. They were also used in savory dishes, such as roasted hazelnuts, hazelnut soup, and hazelnut spread.
In the late 19th century, hazelnuts began to be cultivated in the United States, particularly in Oregon and Washington. In the early 20th century, hazelnut production in the United States increased significantly, with Oregon producing an estimated 30 million pounds in 1919.
Today, hazelnuts are a popular ingredient in many recipes and products. They are used to make the popular Nutella spread and are often used as a topping for desserts, such as ice cream and cakes. They are also widely used in savory dishes, such as salads and pesto sauce. Hazelnuts are also widely used in baking, such as in biscuits, cookies, and cakes.
Cooking with Hazelnuts
To start off, let’s talk about the flavor of hazelnuts. These nuts have a mild yet distinctive flavor that’s slightly sweet and nutty. It’s a flavor that pairs well with both sweet and savory dishes, so it’s no surprise that they’ve become a popular addition to many recipes.
One of the best ways to enjoy the flavor of hazelnuts is by roasting or toasting them. Roasting nuts brings out their flavor and makes them crunchier. To roast hazelnuts, spread them on a baking sheet and bake in a 350°F oven for 10-15 minutes, stirring halfway through. Toasting hazelnuts is even simpler, just spread them in a single layer on a baking sheet and toast in a 350°F oven for about 5-10 minutes, until lightly golden brown.
In addition to using hazelnuts in their roasted or toasted form, you can also grind them up for use in baking recipes. To grind hazelnuts, use a food processor or spice grinder. Pulse the nuts until they’re chopped into a coarse meal. This is perfect for adding to cookies, muffins, and other baked goods for a nutty crunch.
If you’re looking for a healthier alternative, hazelnuts can also be used raw. Raw hazelnuts are full of protein, fiber, vitamins, and minerals, making them an excellent addition to salads, smoothies, and even oatmeal. You can also sprinkle them on yogurt or oatmeal for a boost of flavor and nutrition.
To keep your hazelnuts as fresh as possible, store them in an airtight container in the refrigerator. This will help prolong their shelf life and keep them tasting their best.
Clinical Trials on Hazelnuts
One of the most common clinical trials on hazelnuts is to assess their effects on cholesterol levels. Studies have suggested that consumption of hazelnuts may help reduce total cholesterol levels, including both LDL (bad) cholesterol and HDL (good) cholesterol. Research suggests that the monounsaturated fats and other nutrients found in hazelnuts may help reduce the risk of cardiovascular disease.
Another area of clinical trials with hazelnuts is to evaluate their potential to lower blood sugar levels. Research has suggested that hazelnuts may help improve glycemic control in people with diabetes, as well as reduce fasting blood sugar levels in those without the condition. Studies have also suggested that consuming hazelnuts may help reduce the risk of developing diabetes.
One of the more recent areas of research with hazelnuts is to assess their potential weight management benefits. Studies have suggested that hazelnuts may help reduce appetite and cravings, as well as support healthy weight loss. Additionally, research suggests that hazelnuts may help improve metabolism and increase fat burning.
