Seaweed: An Undervalued Superfood from the Ocean
When it comes to nutrient-rich foods that offer health benefits, most people think of nuts, fruits, or vegetables. Little do they know that seaweed, a plant that grows in the vast ocean, is a treasure trove of nutrition, promoting health and well-being from within.
Seaweed is packed with vitamins A, C, E, and B-complex, as well as essential minerals such as iodine, iron, copper, and manganese, along with plant-based omega-3s. Moreover, seaweed proteins contain all the essential amino acids, supporting muscle health and metabolism. Notably, fucoxanthin, a powerful antioxidant found in brown seaweed, has been proven to be 13 times more potent than vitamin E in protecting cells from free radical damage.

Heart Health, Cholesterol, and Stroke Prevention
A 2023 meta-analysis published in Healthline revealed that consuming brown seaweed significantly lowers total cholesterol and LDL (“bad” cholesterol), the primary culprits of atherosclerosis. Seaweed also contains fucan, a natural compound with anti-coagulant properties, which helps reduce the risk of stroke and heart attack.
Dr. Naomi Sato from the University of Tokyo asserts, “Seaweed is not just a delicious food but also a powerful ally in maintaining cardiovascular health. Regular seaweed consumption contributes to a healthy heart and lowers the risk of cardiovascular diseases.”
Additionally, animal studies have indicated that peptides found in seaweed may aid in regulating blood pressure, reducing strain on the heart.
Blood Sugar Control and Diabetes Prevention
An eight-week study in Japan found that individuals who took 2 mg of fucoxanthin from seaweed oil daily significantly improved their blood sugar control, especially those at risk of insulin resistance. Furthermore, alginate, another compound present in seaweed, slows down the absorption of sugar after meals, thus preventing spikes in blood sugar levels, a key risk factor for type 2 diabetes.
Even a small amount of seaweed in your diet is sufficient to support natural blood sugar balance. You don’t need to consume large quantities.

Iodine for Thyroid Health and Improved Digestion
Seaweed is renowned for its abundant natural iodine content, which is essential for the proper functioning of the thyroid gland and the production of metabolism-regulating hormones. Seaweed also contains the amino acid tyrosine, which, along with iodine, is crucial for the formation of thyroid hormones.
It’s worth mentioning that seaweed is an excellent source of dietary fiber, comprising 35-60% of its dry weight. This fiber nourishes beneficial gut bacteria, promotes a healthy digestive system, and prevents constipation. Sulfated polysaccharides in seaweed also create a favorable environment for the growth of beneficial bacteria, thereby boosting the body’s immune response.
How Much Seaweed Should You Eat?
According to dietary recommendations, incorporating just 5-10 grams of dried seaweed (or the equivalent of 1-2 fresh seaweed leaves) into your daily meals is enough to reap the aforementioned health benefits. However, it’s important to source seaweed from reputable suppliers to ensure food safety and avoid heavy metal contamination.
You can easily incorporate seaweed into soups, salads, sushi rolls, or even enjoy it as a side dish with your favorite beverages.
A Message of Health from the Ocean
Seaweed is a precious gift from the ocean, offering a plethora of health benefits. By including a small amount of seaweed in your daily diet, you can experience improved heart health, enhanced muscular flexibility, and a smoother digestive process. It’s simple yet effective—give it a try!
