Kelp benefits: 5 reasons why everyone loves this Japanese delicacy

People love Japanese cuisine for a variety of reasons, but one of the most popular ones after sushi is kelp, which has a rich flavour and is packed with high nutrients. Kelp is a type of popular seaweed that can be an excellent addition to various cuisines, including chilled salads and savoury soups. It not only tastes great, but it also has a lot of health benefits. It is no surprise that it is gaining popularity around the world. Packed with nutrients and antioxidants, kelp is often considered a superfood of the sea. Know the health benefits of kelp and how to incorporate it into your diet.

What is kelp?

Kelp, known as “kombu” in Japanese, is a large brown seaweed widely used in Japanese cuisine. It grows in shallow, nutrient-rich seawater. It is a key ingredient in dashi, a fundamental soup stock that forms the base of many Japanese dishes such as miso soup, noodle broths, and sauces. Kelp enhances the flavour of many dishes due to the presence of glutamine, a source of savoury taste known as umami, found a study published in the Tokyo Foundation for Policy Research.

Kelp, a type of brown algae, is a rich source of several nutrients and bioactive compounds that can contribute to various health benefits. It contains various nutrients, including iodine, calcium, iron, and vitamins A and C.

5 health benefits of kelp

Here are five reasons why adding kelp to your diet can be beneficial for your health:

1. Reduces inflammation

Kelp, a type of seaweed, contains natural compounds known as carotenoids, which can help combat inflammation, which is linked to many chronic diseases, including arthritis and Alzheimer’s. Carotenoids are also powerful antioxidants that protect our cells from damage, as found in a study published in the Journal of Functional Foods. So, including kelp in your diet could be a tasty approach to improve your health!

2. Regulates thyroid function

Kelp is a natural source of iodine, a trace mineral essential for thyroid hormone production, as found in a study published in the Clinical Chemistry, Immunology and Laboratory Quality Control. The thyroid gland, located in the neck, regulates metabolism, growth, and development of the brain. Iodine deficiency can lead to hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. By providing iodine, kelp can help support thyroid function, ensuring that the body’s metabolism works efficiently.

3. Aids in weight loss

“Kelp is low in calories and fat but high in fibre, particularly a type of fibre called alginate, making it an excellent addition to a weight loss diet. The fibre content promotes feelings of fullness and satiety, lowering appetite and calorie intake, which can aid in weight loss,” says dietician Gauri Anand. However, it is important to note that while kelp can be a helpful addition to a balanced diet, it is not a magic pill. Eating healthy and regular exercise are crucial for sustainable weight loss results.

4. Supports bone health

Kelp contains essential minerals like calcium and magnesium, as found in a study published in the Advances in Food and Nutrition Research, both of which are crucial for bone health. Calcium is the primary building block of bones, while magnesium plays a supporting role in calcium absorption and bone metabolism. “By providing these minerals, kelp can help maintain bone density and reduce the risk of osteoporosis, a disorder characterised by weak and brittle bones. It is important to note that while kelp can contribute to bone health, it is best consumed as part of a balanced diet that includes other calcium-rich food,” explains the expert.

5. Supports cardiovascular health

Kelp is packed with bioactive compounds called fucoidans, as found in a study published in Marine Drugs. These compounds have potential health benefits, especially when it comes to cardiovascular health. Fucoidans are rich in anti-inflammatory and anticoagulant properties, which may help lower blood pressure and reduce cholesterol levels. By reducing inflammation and preventing blood clots, fucoidans may help support cardiovascular health and reduce the risk of heart disease. Incorporating kelp into your diet could be a natural way to improve your heart health.

Are there any side effects of kelp?

While kelp offers various health benefits, it is important to be aware of the potential side effects, as explained by the expert.

1. Iodine overconsumption

Kelp is very high in iodine, which is essential for thyroid function, but too much of it can lead to thyroid dysfunction. Overconsumption can cause hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), particularly in individuals who are sensitive to iodine.

2. Heavy metal contamination

Kelp can absorb heavy metals like arsenic, cadmium, and lead from the ocean. If the kelp is harvested from contaminated water, it may contain harmful levels of these metals, which can pose health risks if consumed for a long time.

3. Digestive issues

Kelp is rich in fibre, which is generally beneficial for digestion, but consuming too much fibre in a short period can lead to digestive discomforts, such as bloating, gas, and stomach cramps.

4. Blood thinning

Kelp contains fucoidan, a compound that may have blood-thinning properties. While this can be beneficial for heart health, it could pose a risk for individuals on blood-thinning medications or those with bleeding disorders.

5. Allergic reactions

Though rare, some individuals may be allergic to kelp or other types of seaweed. Symptoms of an allergic reaction can include itching, hives, swelling, difficulty breathing, or anaphylaxis in severe cases.
