This is Kombu, Kelp.
Left - dried, just like this when you buy at grocery stores.
Right - after cooked, after soaked. 7-8 times bigger than dry one.
Kombu is normally for dashi, soup stock. But we eat sometimes.
But there is no taste, no flavor, no salty, no sweet. It is hard to eat.
This is a typical healthy food, Nimame. Nimame is braised soy bean. I just add konbu.
You know soy bean is good for health, especially for women.
And konbu is mineral and vitamins, all natural and no side effect.

Kombu seaweed is a type of edible plant that is a staple in the Japanese culinary tradition. Kombu seaweed is low in calories but provides several beneficial nutrients. Although Kombu seaweed is usually used as an ingredient in Japanese dishes, you can use it as a garnish or main ingredient in a variety of recipes to provide an improved nutritional profile.
If you're on a calorie-restricted diet, kombu can be a healthy choice, as 1 oz. of this seaweed contains just 83 calories. This amount comprises about 4 percent of the daily suggested intake of 2,000 and can be burned off relatively quickly through exercise. For example, five minutes of rollerblading or nine minutes of jogging could burn 83 calories.
Kombu seaweed is healthful because of its lack of fat. Although dietary fat does provide some benefits, too much of certain fats can be detrimental. Kombu seaweed contains no saturated or trans fats, which are types of fat that can increase your risk of heart disease by promoting adverse changes to your cholesterol levels.
Kombu seaweed is rich in carbohydrates, with 17 g in each 1 oz. serving. Carbohydrates are your body's primary source of energy, so consuming carbohydrate-rich foods can be beneficial for athletes. In fact, exercising and eschewing carbohydrates can be detrimental; a study from the April 2010 issue of the "European Journal of Applied Physiology" found that consuming a low-carbohydrate diet and performing intense exercise led to a decrease in testosterone levels.
Another healthful aspect of Kombu seaweed is its rich fiber content. Each 1 oz. serving of Kombu seaweed provides 7 g of fiber, a nutrient that promotes a variety of benefits. Dietary fiber can help you manage your cholesterol levels, promote bowel health and aid in weight loss by stimulating feelings of fullness.
Kombu seaweed is rich in calcium, with 13 percent of the daily suggested intake in each 1 oz. serving. Eating a diet rich in calcium is healthful because this mineral promotes strength in your bones and teeth and may help reduce your risk of high blood pressure and PMS, according to the University of Maryland Medical Center.
Kombu seaweed is rich in iron, with 13 percent of the daily suggested intake in each 1 oz. serving. Iron promotes a number of health benefits, as it helps produce cellular energy and aids in carrying oxygen to your body's cells.
I sometimes just eat dried kombu. It is salty and chewy but just eat. You had better choose thin one. Don't try with thick one, hard to chew.
Be healthy! Right?
