Seaweed Side Effects for Health

Seaweed Side Effects for Health

Here we are going to discuss seaweed side effects and health considerations:

Excessive Iodine Intake

  • Seaweed is naturally high in iodine, and consuming too much can lead to thyroid issues like hypothyroidism. The recommended daily iodine intake is less than 1,100 micrograms.
  • Certain groups like children, infants, and those with thyroid disorders should be especially careful about excessive iodine from seaweed.

Heavy Metal Accumulation

  • Seaweed can absorb and accumulate heavy metals like cadmium, mercury, and lead from its environment. Long-term, high consumption of seaweed may lead to a buildup of these toxic heavy metals in the body.
  • Buying organic seaweed can help reduce the risk of heavy metal exposure.

Medication Interactions

  • Seaweed is high in potassium, which can be harmful for those with kidney disease.
  • The vitamin K in seaweed may interact with blood-thinning medications like warfarin. Individuals taking these medications should limit seaweed intake.

Other Potential Side Effects

  • Skin reactions, goiter, and occasional intestinal effects have been reported with seaweed consumption.
  • Excessive dried seaweed intake may increase thyroid-stimulating hormone levels.
  • There have been rare cases of yellowing of the skin from excessive seaweed consumption.

In summary, while seaweed offers many potential health benefits, it's important to be mindful of the risks of excessive iodine, heavy metal accumulation, and interactions with certain medications. Moderation and awareness of these considerations is key when incorporating seaweed into the diet.
