Late-night social media scrolling can bombard you with various dietary advice, often exaggerated, promoting trendy foods or supplements as miracle solutions for all health issues, ranging from gut health improvement to weight loss, which may not always be necessary. Konjac is a well-liked ingredient in low-carb diets such as keto. According to Michelle Routhenstein, a preventive cardiology dietitian and certified diabetes educator, konjac is a root vegetable from Southeast Asia known for its soluble fiber, glucomannan, which is beneficial for weight management and digestive health. But does konjac truly live up to the hype? Registered dietitians provide insights on konjac’s benefits, risks, taste, and where to find it.
Konjac, also known as devil’s tongue or elephant yam, is a root perennial plant originating from China and Southeast Asia. It is rich in soluble fiber and low in calories, carbohydrates, and fat, making it popular for its potential health benefits in preventing and treating various conditions. Konjac is commonly processed into flour, jelly, noodles, and dietary supplements. Glucomannan, the water-soluble fiber in konjac, has been linked to delaying stomach emptying, promoting satiety, and aiding in weight loss. However, it’s essential to note that dietary supplements are not regulated as strictly as drugs by the FDA, and caution is advised when considering konjac supplements due to potential risks associated with some products.
Before incorporating konjac into your diet, it is advisable to consult with a healthcare professional, especially if you are taking medications that affect blood sugar levels. Konjac itself has a neutral taste, allowing it to absorb the flavors of other ingredients, with a slightly rubbery and gelatinous texture. It is versatile and can complement a variety of dishes. When seeking konjac products, look for flour, jelly, noodles, or dietary supplements.
