Is Seaweed the Next Big Superfood?

By Cynthia Sass, MPH, RD.

The other day as I walked through Whole Foods, I felt like I was in an aquarium. Everywhere I looked I saw seaweed! Seaweed snacks are the new coconut water, and varieties like wakame are popular in prepared dishes such as chilled seaweed salad.

It seems that sea veggies are a hot new superfood, with reported benefits ranging from heart protection to weight loss. Currently researchers are studying potentially protective compounds in eight species of seaweed from Ireland and Canada that may help reduce blood clots and hardening of the arteries , two major risk factors for heart disease. Another recent report published in the Journal of Agricultural and Food Chemistry reviewed almost 100 previous studies and concluded that some seaweed proteins work just like blood pressure meds. And in animal research a component in brown seaweed was shown to help rats burn more body fat.

Research aside, sea vegetables , including kelp, nori, hijiki, wakame and others are rich sources of iodine and one of the few sources of this important mineral- just a quarter of a cup packs a whopping 275 percent of the daily value. Too little iodine can trigger hypo or hyperthyroidism, fatigue, weight gain, and depression. And they're also a good source of magnesium, which can improve sleep and alleviate hot flashes in women going through menopause.

To reap the benefits try out a dried seaweed snack, such as Annie Chun's. The sesame variety is made from just seaweed, canola oil, sesame oil and salt (so no artificial extras), and 10 sheets contain just 30 calories and 70 mg of sodium. Plus they're portable, and you can crumble them as a topping for a garden salad or stir fry.
