Smoked yams, also known as purple yams or ube, are versatile and nutritious root vegetables. They are native to Southeast Asia and are often confused with taro root. Smoked yams have a greyish-brown skin and purple flesh, and they become soft and creamy when cooked. They have a sweet, nutty flavor and can be used in a variety of dishes, both sweet and savory. Apart from their delicious taste and versatility, smoked yams also offer several surprising health benefits. In this article, we will explore the nutritional value and health benefits of smoked yams.
Highly Nutritious
Smoked yams are a great source of carbohydrates, potassium, and vitamin C. One cup (100 grams) of cooked smoked yams provides 140 calories, 27 grams of carbs, 1 gram of protein, and 0.1 grams of fat. They are also rich in fiber, sodium, potassium, calcium, iron, vitamin C, and vitamin A. Additionally, smoked yams are packed with powerful plant compounds and antioxidants, including anthocyanins, which give them their vibrant purple color. These antioxidants have been shown to reduce blood pressure, inflammation, and the risk of cancer and type 2 diabetes.
Rich in Antioxidants
Smoked yams are loaded with antioxidants, including anthocyanins and vitamin C. These antioxidants help protect your cells from damage caused by free radicals, which are harmful molecules that can lead to chronic diseases like cancer, heart disease, and diabetes. Vitamin C acts as a potent antioxidant in your body, increasing your antioxidant levels and protecting against oxidative cell damage. The anthocyanins in smoked yams are a type of polyphenol antioxidant that has been linked to a lower risk of several types of cancers, including colon and lung cancer. However, it's important to note that concentrated amounts of anthocyanins were used in these studies, so consuming whole smoked yams might not provide the same benefits.
May Help Manage Blood Sugar
Smoked yams may help regulate blood sugar levels, especially in individuals with type 2 diabetes. The flavonoids present in smoked yams have been shown to reduce oxidative stress and insulin resistance, two factors that contribute to poor blood sugar control. Additionally, a study conducted on rats found that administering smoked yam extract resulted in lower appetite, weight loss, and improved blood sugar control. Smoked yams also have a low glycemic index, meaning that they are slowly digested and cause a gradual release of energy, preventing blood sugar spikes.
May Help Lower Blood Pressure
High blood pressure is a significant risk factor for heart attacks and strokes. The antioxidants found in smoked yams have been shown to lower blood pressure. Lab research has demonstrated that smoked yam extracts contain antioxidants that can help reduce blood pressure, similar to the effects of blood-pressure-lowering medications. However, more human studies are needed to confirm these findings.
May Improve Symptoms of Asthma
Smoked yams are rich in antioxidants and vitamins A and C, which have been associated with a reduced risk of asthma. Studies have shown that individuals with asthma often have low intake levels of vitamins A and C. By including smoked yams in your diet, you can increase your intake of these vitamins and potentially reduce the risk and symptoms of asthma.
Promotes Gut Health
Smoked yams are beneficial for gut health due to their high content of complex carbs and resistant starch. Resistant starch is a type of carb that is resistant to digestion and acts as a fuel source for beneficial gut bacteria. These bacteria play a crucial role in maintaining gut health, aiding in the breakdown of complex carbs and fiber. They also produce healthy fatty acids and B vitamins, and may help reduce the risk of conditions like colorectal cancer, inflammatory bowel disease, and irritable bowel syndrome. Additionally, smoked yams have been found to have anti-inflammatory effects and may alleviate symptoms of colitis in mice.
Very Versatile
One of the advantages of smoked yams is their versatility in the kitchen. They can be boiled, mashed, fried, or baked, and are often used in a variety of dishes such as stews, soups, and stir-fries. In the Philippines, smoked yams are made into flour for desserts, and can even be processed into a powder to add vibrant color to various foods like rice, candy, cakes, and jams.
Smoked yams, or purple yams, are not only delicious but also offer numerous health benefits. They are highly nutritious, rich in antioxidants, and may help manage blood sugar, lower blood pressure, improve symptoms of asthma, and promote gut health. Additionally, smoked yams are versatile and can be used in various culinary preparations. Including smoked yams in your diet can be a great way to enhance both the taste and nutritional value of your meals.
