5 Benefits Of Seaweed That You Didn’t Know

Seaweed or macroalgae is a reference to thousands of marine and macroscopic algae species. This term consists of certain forms of macroalgae of rhodophyte (red), phaeophyte (brown and green). Marine species, for the sake of fisheries and other marine species such as kelps, provide an important nursery habitat to preserve and protect food resources; other species such as planktonic algae play an essential role in the carbon capture and produce oxygen. Identifying these functions provides conservation and sustainable use concepts. For example, mechanical kelp dredging damages the resources and fisheries that are dependent upon it.

“Seaweed” does not have a standardised meaning, but implies an ocean association prerequisite and is visible to the naked eye. The word is used to mean all flowering plants immersed in the ocean and eelgrass, but also the larger marine algae. It is generally one of several cell groupings: red, green, and brown. There is a mutual, polyphenylene community without a common multicellular cancer. The number of algae species is still being discussed by scientists, but there are most likely several thousand algae in the world.

Seaweed is all of the sea: algae red, green or brown that thrive along the coastline. Seaweeds are usually anchored by root-like “holdfasts” to the sea floors or other strong structures that play the sole role of the attachment and do not absorb nutrients like higher plant roots. Several algae are edible and many are also commercially important for humans.  These are also used as fertilisers or polysaccharide sources.

Sea algae types include:

  • Nori
  • Kombo 
  • Dulse
  • Blue-green algae like chlorella and spirulina
  • Wakame 
  • Kelp 

This variety can easily integrate algae into various recipes. But too much seaweed should not be consumed by people.

Benefits of seaweed

Seaweeds have high nutritional content but are lesser-known to people.

  • Contains iodine and tyrosine, which helps the thyroid

The thyroid gland produces hormones to help regulate development, generation of energy, reproduction and cells in your body. To produce hormones, your thyroid is dependent on iodine. You may get signs such as weight changes, tiredness, or neck swelling if you do not consume enough iodine. The minimum intake of iodine (RDI) is 150 mcg daily.

Seaweed is capable of consuming concentrated iodine which is found in the oceans. The content of iodines depends heavily on the form, the location and how it is grown. Indeed, 11–1 989% of RDI can be contained on a dried sheet of seaweed.

  • The abundance of vitamins and minerals 

A unique set of nutrients is available for each type of seaweed.

It not only adds taste, texture and flavour to your meal by sprinkling some dried seaweeds on your food but also makes your intake of vitamins and minerals easier and nutritious. In general, dried seaweed one tablespoon can provide:

  • Calories: 20 grams
  • Carbs: 1.7 grams
  • Protein: 4 grams
  • Fat: 0.5 grams
  • Ballast: 0.4 grams
  • 15% of the RDI was Riboflavin
  • Thiamin: 11% of the RDI
  • Iron: 11% of the RDI
  • RDI: 7 percent Manganese
  • Copper: 21% of the RDI

Tiny quantities of vitamins A, C, E and K are also presented in the Seaweed, along with folate, zinc, sodium and calcium. According to research, seaweed nutrition is rich in several vitamins and minerals.

  • protein
  • carbohydrates
  • fibre
  • minerals
  • polyunsaturated fatty acids
  • Helps with diabetes

Diabetes can be helped by fibre-rich food. High concentrations of fibre help control levels of blood glucose and insulin. Incorporating marine algae to the food will increase your intake of fibre without dramatically rising calories. 

In a 2018 rat study, compounds in one form of sea algae could directly reduce markers such as high blood sugar, for example, type 2 diabetes. Seaweed compounds also decrease risk factors for diabetes, such as inflammation and high fat and intolerance to insulin. Further research is required to get more evidence with its ability to fight diabetes.

Seaweeds are rich in fibre. These fibres are low in calorie content. Seaweed fibre helps curb and reduce hunger and you eat less than usual. It also makes you feel full sooner, this allows you to feel more satisfied and can slow down your hunger. The anti-obesity benefits of seaweed also are considerable. 

Several animal studies indicate in particular that seaweed or macroalgae can reduce fat in a substance in seaweed. A studio has found that rats that have taken fucoxanthin have lost weight while rats that were given the control diet have not. Fucoxanthin has been shown to enhance the protein metabolization expression of fat in rats.

  • Is good for heart health

High fibre foods such as algae can also minimise blood cholesterol levels according to a study. The soluble fibres bind to bile acids or body salts. Cholesterol is then used by the body to replace this portion, resulting in a decrease of up to 18% in total cholesterol. Many kinds of algae also have high antioxidants, which over time can improve heart health. Cardiovascular disease is the world’s leading death cause. 

High Cholesterol, hypertension, smoking, being inactive or overweight are all factors that raise the danger. Interestingly, marine algae can help lower your blood cholesterol. Excessive blood clotting can also cause heart disease. Seaweed contains carbohydrates known as fucans that may prevent coagulation of the blood.

Risk involved

While marine algae are considered to be very healthy food, they can still be risky to consume in large quantities.

  • Iodine 

A massive, potentially hazardous amount of iodine may be found in marine algae.

  • Loading of heavy metal

This presents a risk to human health as seaweed may contain a high accumulation of heavy metals such as cadmium, mercury and lead as well. Seaweed can absorb and store minerals in concentrated amounts.

Several recettes can be boosted when seaweeds are added to food, the nutritional content encourages a healthy diet, and people are also able to use algae instead of salt. It also includes additional vitamins and minerals such as vitamin K, B vitamin, zinc and iron, as well as antioxidants to avoid damage to your cell. 

But too much seaweed iodine will harm your thyroid function. Take this ancient component in daily yet small quantities for optimal health benefits. However, it is a safe idea for some people to avoid algae. Thyroid medicine can be taken before adding seaweed to a diet or a doctor must be consulted.
