Seaweeds and Algae as Functional Foods: What Are the Potential Benefits?

In the world of nutrition, 'functional food' is a concept that has gained popularity. It refers to foods which have an effect beyond nutrition. We'll explore two of these foods today: algae and seaweed. They are not just for feeding fish. These plants can be beneficial to human health as well.

Seaweeds and Algae are important functional foods

These seaweeds and algae are not only for sushi. These marine plants are nutritional powerhouses. The National Institutes of Health found that both seaweeds and algae were rich in nutrients. These included vitamins A, C and E, as well as several B vitamins and trace minerals such iodine and selenium.

They are also excellent sources of dietary fibre and antioxidants, both of which help to protect the digestive system and reduce oxidative damage. Moreover, studies have shown that algae and seaweed may be anti-inflammatory, promote heart health and help with weight loss. Moderation is the key, as excessive consumption of seaweed and algae can cause gastrointestinal discomfort, iodine overload, or a rash.

How to Start with Seaweeds and Algae

It's much easier to incorporate seaweed and alga into your daily diet than you may think. These marine plants are now available in many health food shops and supermarkets. Try adding seaweed powder to smoothies and salads. You can also add dried seaweeds.

It's important to keep in mind that seaweeds and algae may be high-iodine, even though they are safe for the majority of people. Consult your healthcare provider if you have thyroid problems or any other concerns.

Seaweeds and algae are functional foods because of their nutrient-rich profile and health benefits. They should, however, be included in a healthy diet. Any significant changes should also be discussed with your healthcare provider. Next time you need a boost in nutrients, consider consuming seaweed or algae.
