Although Kombu mainly contains carbohydrates, these carbohydrates would not make you gain weight. Therefore, it is suitable for most weight loss plans. 

Nutritional Benefits of Kombu

Owing to the constituents mentioned above, Kombu possesses several health benefits. Although, active research with complete evidence can substantiate whether seaweed can benefit your body. With seaweed, the process of manufacturing the product is tedious. Hence, the health benefits are not entirely clear. More human-based studies are required to confirm these benefits. Even then, some health benefits observed by the people who consume Kombu regularly are listed below. 

Rich in Vitamin K

Kombu contains a good amount of vitamin K, contributing to the daily intake value. Vitamin K aids in the blood coagulation or clotting process. Therefore, it can eventually improve blood quality. Vitamin K can also impact calcium in the body and boost your bones’ strength. 

High Fibre Content

Kombu contains fibre that aids in digestion and maintains bowel movement. Thus, you need not worry about irregular bowel movements while consuming Kombu. This fibre content also prevents diabetes and can promote heart health. 

Contains Amino Acids

Kombu contains glutamic acid- alpha-amino acid. This amino acid acts as a precursor or a pioneer of protein synthesis in the ribosomes. Thus, it is of great importance to the body. Also, this amino acid is what gives the Umami taste to Kombu. Additionally, glutamic acid helps break down the carbohydrates in beans. Also, this helps to prevent gas formation.

Iodine in Kombu can Prevent Anaemia.

Kombu contains exceptionally high levels of iodine that aid in producing thyroid hormones. These thyroid hormones help the body’s overall development, especially during pregnancy and lactation. They also aid in the development of the nervous system of the body. Iodine may also prevent some forms of cancer and increase the life span, especially in males. In addition, studies show that hypothyroidism gets cured with Kombu. The deficiency of iodine can cause hypothyroidism, whereas an excess of iodine may cause hyperthyroidism. 

Rich in Magnesium

Kombu contains trace amounts of magnesium that can contribute to your regular intake value. This magnesium can cure fatigue. In addition, magnesium regularises the cell cycle of the body. Magnesium also contributes to the bone and teeth strength of the body. According to research, magnesium deficiency contributes to osteoporosis.

Rich in Potassium

Kombu contains a good amount of potassium as well. This potassium helps maintain the blood pressure level and improves the quality of the blood. Also, potassium helps in muscle formation. It also regulates the nervous system of the body. 

Fat-Free

By observing the USDA research, we can conclude that a serving of Kombu does not contain fats. Hence, one can use it in keto or other diets to help lose weight. Nevertheless, you must be cautious of choosing the recipe as the recipe may contain variable amounts of fats. 

Since Kombu is a popular food in Japan, you can witness these benefits in most Japanese populations. In addition, most studies show that certain sections of the Japanese population experience well-developed bones and increased lifespan and other distinguishing features compared to other countries due to the regular consumption of Kombu (seaweed) which contains high amounts of iodine.

Seaweed Allergy

This allergy is not limited to only Kombu; it is typical for all seaweeds. It is not necessary that if you are allergic to seafood, you would be allergic to seaweed as seaweeds do not contain fish protein. Even then, it is wise to opt for a doctor consultation before consuming seaweed as it may lead to an allergic reaction if started abruptly.
