Seaweed a Superfood: a Nutrient-Rich Solution for Modern Diets

Abstract Seaweeds, also called macroalgae, are an abundant renewable resource that flourishes on India's northwest and southeast coasts. They create bioactive chemicals with a wide range of health benefits while thriving in a variety of harsh settings. Seaweeds supply vital materials, including agar, alginate, and carrageenan, and are widely used in industries for their gelling, stabilizing, and thickening capabilities. These are essential in the food, pharmaceutical, and other industries. Seaweed's rich nutritional profile is one of its main health advantages, particularly when it comes to treating vitamin B12 deficits, which are prevalent in pregnant women, the elderly, and vegetarians. Active vitamin B12, which is essential for many body processes, including the synthesis of red blood cells and neurological function, is known to be present in several seaweed species, such as purple laver. Seaweeds are rich in essential nutrients like proteins, amino acids, polyunsaturated fatty acids, vitamins, minerals, and polyphenols, all of which contribute to overall health. They provide essential amino acids, beneficial fatty acids for cardiovascular and brain health, and important minerals like iodine, calcium, iron, and magnesium for thyroid health and general well-being. The polysaccharides in seaweed, such as alginate and carrageenan, offer functional benefits, while their polyphenols provide antioxidant and anti-inflammatory properties. Despite these health benefits, seaweeds are underutilized in the food industry. Fortifying products like crackers and biscuits with seaweed could help address nutritional deficiencies, especially vitamin B12. Overall, seaweed has great potential as a sustainable food source that can improve nutrition and prevent diseases.
