Dried seaweed

Dried seaweed refers to a variety of edible seaweeds that have been collected from the ocean, dried and processed for consumption. These seaweeds are widely used in various cuisines worldwide and come in a variety of forms, including sheets, flakes, and strips. The term “sea vegetables,” or dried seaweed, refers to a variety of marine algae species that are collected, dried, and then often eaten for their high nutritional value. They come in a variety of colors – red, green, brown and black – and provide food for marine life.

Vitamins (A, C, E, and K), minerals (iodine, calcium, iron, and magnesium), antioxidants, and fiber are some of the nutrients that are high in seaweed. Dried seaweed is a versatile, high-nutrition food additive that, when included in a balanced diet, provides many health benefits in addition to giving food a unique flavor.

Seaweeds (macroalgae) are marine bioresources rich in a range of valuable ingredients that are used in food, pharmaceutical, cosmetic, and animal feed applications. They are viewed as a low-investment crop and are readily available in coastal environments. Apart from macronutrients, edible seaweeds are valued for the abundance of naturally occurring bioactive compounds like phenolics, flavonoids, and antioxidants, finding numerous applications in the food and nutraceutical industries.↗️

The Power of Antioxidants

Dried seaweed, rich in antioxidants like flavonoids and carotenoids, is a powerful ally in the fight against oxidative stress. These substances fight free radicals, protect cells from damage and support a strong immune system, potentially lowering the risk of chronic diseases. As a result, consistent use can reduce the likelihood of chronic illness. Free radicals are substances that contribute to chronic diseases, like cardiovascular diseases, diabetes, and certain types of cancer. Antioxidants can also boost your immune system.

Rich in Essential Nutrients

Dried seaweed is one of the best natural sources of iodine, which is essential for healthy thyroid function. A healthy diet that contains a balanced amount of iodine promotes general well-being, regulates metabolism, and helps produce thyroid hormones.

This seafood is very rich in vitamins. Collagen production and skin health are promoted by vitamin C, which strengthens the immune system. In the meanwhile, vitamin A supports healthy immunological function, cell division, and eyesight. Additionally, dried seaweed is one of the few plant-based sources of vitamin B12, which is essential for DNA synthesis and nerve function.

Dried seaweed is rich in calcium and is essential for healthy bones and muscles. When combined with magnesium, it promotes cardiovascular health, helps relax muscles and maintains bone density.Dried seaweed is a rich source of iron that supports the body’s oxygen transport system.

Dried seaweeds antioxidants fight oxidative stress, shielding blood vessels from harm and lowering the risk of atherosclerosis to support a healthy cardiovascular system.

According to a 2021 study in Phytomedicine Plus, certain chemicals in kelp, specifically fucoidan, fucoxanthin, astaxanthin, and phlorotannin, may have beneficial effects on the heart.

Dried seaweed’s potassium and magnesium contents help control blood pressure. Together, these minerals promote smooth muscle contraction, which lowers the risk of hypertension and helps dilate blood vessels.

A 2011 review of 100 studies on the effects of seaweed published in the American Journal of Agricultural and Food Chemistry found that seaweed can be used to lower blood pressure and support heart health.

Some seaweeds, such as kelp, include omega-3 fatty acids, which help decrease blood triglyceride levels and reduce inflammation. This lowers blood pressure and lowers the risk of cardiovascular problems.

Fiber helps control cholesterol. Ultimately, soluble fibers improve heart health by binding to cholesterol in the digestive tract and blocking its absorption, maintaining a healthy cholesterol profile.


Strengthening Bone Density

Dried seaweed contains calcium and magnesium, which are very beneficial to bone health. Including this high-nutrient item in one’s diet may help strengthen bone density and lower the risk of osteoporosis and associated conditions.

Dried seaweed appears to be a powerful source of calcium, which is essential for healthy bones. Including this seafood in your diet will naturally increase your calcium intake, which is essential for healthy bones.

A vitamin essential for calcium absorption and bone health, vitamin D is present in certain dried seaweeds. Adequate levels of vitamin D promote optimal calcium utilization, strengthen bones, and reduce the risk of fractures. Also, vitamin K is present in dried seaweed. Calcium helps regulate and contributes to bone mineralization, while vitamin K helps maintain strong and healthy bones.


It may help with diabetes

Studies have shown that fucoxanthin and alginate, two substances found in dried seaweed, may help control blood sugar levels. A color found in brown seaweed called fucoxanthin has been shown to possibly make insulin work better, which could help with better glucose control.

A pigment called fucoxanthin has been found in brown seaweed that may have been shown to make insulin work better, which may help with better glucose control.

Also, certain proteins in dried seaweed, such as alginate, help with insulin intolerance, a common problem in people with type 2 diabetes. It’s possible that these fibers can slow down the absorption of sugar, which can help stabilize blood sugar levels after a meal.

A 2018 study in mice found that chemicals in a type of seaweed can directly reduce symptoms of type 2 diabetes, such as high blood sugar.



May Aid Cancer Prevention

Fucoidans found in certain types of kelp have shown promise in laboratory studies for their ability to inhibit the growth of cancer cells and induce apoptosis (cell death) in these cells.

Antioxidants like flavonoids and polyphenols, which are abundant in dried seaweed, are well-known for their capacity to scavenge oxidative stress and eliminate free radicals. These substances have a major impact on lessening cellular damage, which may reduce the chance of developing certain malignancies.

Although excessive iodine intake may be detrimental to thyroid function, studies have shown that a particular type of iodine present in seaweed may be protective against certain thyroid malignancies; However, this area needs more research.

Seaweed has antioxidants, much as other veggies (such vitamin C and beta carotene). These substances have a reputation for preventing cancer, particularly when included in a diet high in nutrients rather than taken as supplements.

According to research, seaweed extracts may improve the prognosis for colon cancer patients by modifying the loss of calcium-sensing receptors (CaSRs) on cancer cells. Seaweed eating as part of a regular diet is often cited as the reason for Japan’s low breast cancer incidence.↗️
