    Seaweed is being used more and more in a variety of foods, here are some ways to incorporate into your daily diet

    While rumor suggests that some seaweed varieties taste like bacon, not everyone likes it eat it by itself. There are many ways to enjoy seaweed. Here are some of the most popular:


    Nori is most commonly known for wrapping sushi, however it can be eaten plain as a snacking alternative. You might like it as a healthy, salty tasting snack. Just make sure to check your teeth for green specs after. 


    Spirulina is one of the oldest life forms on Earth, it is known as the world’s first superfood and is one of the most nutrient-rich foods on earth. Spirulina was consumed by the ancient Aztecs but became popular modernly when NASA proposed that it could be grown in space for use by astronauts. It’s a great source of natural protein so try using the powdered form in smoothies or your pre/post workout drinks.

    seaweed reduces pollution

    Seaweed could save the environment.

    Seaweed grows quickly and is a sustainable source for food and all the uses people can find for it. As the need for sustainable products with low-impact on the environment becomes increasingly vital, these sea vegetables are a solution to many problems we face in 2019. 

    Seaweed has proven itself as a sustainable source of food. Even more interesting, and possibly offering even more sustainability opportunities, is the other ways seaweed has been used to create environmentally-friendly product options. 

    Seaweed is being used in meat replacements.

    The meat industry contributes greatly to greenhouse gasses. Cutting back on meat cuts back on these emissions. Seaweed is used in food sources instead of animal products.

    Agar, which is derived from red seaweed, is a animal-free substitute for gelatin. It can also be used as a thickener for soups and puddings, jams, and jellies. 

    Seaweed is used in a variety of meatless products from burgers to spaghetti. 

    A study estimated that a seaweed farm covering 180,000 square kilometers could provide enough protein for the world’s population. A seaweed farm also has the added benefit of reducing waste and seaweed is actually nourished by the waste products of fish.  

    Seaweed not only reduces the emissions caused by meat farming, it actually improves the quality of our environment.

    seaweed farming

    Seaweed farming cleans the air.

    Feeding seaweed and algae to cows has been shown to reduce their methane emissions by about 20 percent--in simple terms, after eating seaweed cow burps decreased which means less pollution in the air. An estimated 14 percent of the world’s greenhouse gases is caused by agriculture so decreasing that by 20 percent would make a significant difference.

    Farming seaweed could play a significant part in cleaning up our air. Saltwater plants can take up to 20 times more C02 from the atmosphere than forests on the land. The amount of carbon seaweed can absorb could have significant impacts to balance the emissions that cities put out into our air. 

    Kelp has potential to reduce the levels of atmospheric carbon and is a fast-growing alternative to land plants.

    Seaweed is a sustainable plastic alternative.

    A company in Portland has developed a plastic out of algae. It dissolves in water and is non-toxic. Plastic is a huge problem because it’s sitting in our landfills. It’s floating in our oceans, blocking the flow of water, and harming wildlife. Algotek is working to eliminate single-use plastics. It can be made into bags, utensils, and it’s even edible. 

    Seaweed can be used as fertilizer.

    The rich nutrients in seaweed are not only good for you, they’re good for your plants. Seaweed can be mixed in with garden soil to add potassium, phosphorus and other elements that are good for the soil. 

    These are just some of the uses people have found for this water plant. Comment below to let us know how you incorporate seaweed into your life.
