Investigating the Health Benefits of Seaweed Consumption?
Seaweed, a nutrient-rich superfood, has been gaining popularity in modern diets due to its numerous health benefits. This marine plant is a veritable treasure trove of minerals, vitamins, and antioxidants that could boost heart and digestive health, and even support weight loss efforts.
Rich in thyroid-supporting iodine, seaweed is a valuable addition to any diet. However, consuming too much seaweed can lead to iodine overload, which could be harmful to the thyroid. To prevent this, eating seaweed in moderation and pairing it with certain vegetables like broccoli, cabbage, and bok choy can help maintain a balanced intake.
A gram of sea moss offers a substantial 47 mg of iodine, making it a potent source of this essential nutrient. But the iodine count in dried seaweed can vary significantly, ranging from 16 micrograms (mcg)/g to 2,984 mcg/g. Boiling kelp for 15 minutes can reduce its iodine content by up to 90 percent.
Seaweed's nutritional profile extends beyond iodine. It is a rich source of several nutrients that may support thyroid function, gut health, and weight loss efforts. For instance, it contains sulfated polysaccharides, which the good bacteria in your digestive system adore. The fiber in seaweed feeds the good bacteria in your gut and keeps things moving.
The antioxidant properties of seaweed are another reason for its popularity. It contains antioxidants like flavonoids, carotenoids, vitamins A, C, and E. Brown seaweed, in particular, contains a carotenoid called fucoxanthin, which has 13.5 times the antioxidant power as vitamin E.
Some types of seaweed may offer immune system support, as suggested by limited research. A 2015 research review found that the fucoxanthin in edible brown seaweed might have positive effects on obesity. However, while preliminary research is promising, there's not enough solid evidence to say for sure if eating seaweed can help people lose weight.
A 2020 research review with mice found that the mice who received red seaweed extract daily for 12 weeks lost more body fat than the ones who took a placebo, hinting at potential weight loss benefits. Seaweed may also have beneficial effects on blood sugar regulation, according to a small 2017 study and a 2018 study with rats.
Certain bioactive peptides in seaweed may help manage blood pressure, making it a potential ally in maintaining cardiovascular health. Seaweed is also a good source of several essential minerals, including Magnesium, Calcium, Iron, Zinc, Potassium, and Vitamins C and E.
Seaweed can be incorporated into various dishes, from seaweed salads and sushi to dried seaweed snacks, smoothies, baked goods, yogurt, oatmeal, soups, and stews. In Germany, 'Tranquillo Rock 'Retro' seaweed' is available for pickup in Reutlingen, typically ready within an hour, while 'Hikari Seaweed Extreme with Nori' for marine herbivorous fish is available through local suppliers. Unfortunately, some seaweed snacks like Sea Crunchy Nori are currently out of stock with no immediate availability indicated.
In conclusion, seaweed is a nutrient-dense superfood that offers numerous health benefits. However, to reap these benefits, it's crucial to consume seaweed in moderation and ensure it's sourced from clean waters to minimise the risk of heavy metal contamination. As always, consult with a healthcare professional before making significant dietary changes.
