[seaweed roasted]Seaweed is known as a superfood with significant benefits to our bodies. But with everything, there will be a downside if used incorrectly or used too much.
May cause thyroid problems
Iodine is an important substance with the functioning of the thyroid gland. Seaweed is rich in iodine, so eating seaweed enhances thyroid function and prevents goiter.
However, if we consume too much iodine, it will cause bad effects on the thyroid. Scientists have shown that the average amount of iodine consumed in a day should not exceed 3mg, while a serving of seaweed can contain up to 20-50mg of iodine. So we should only eat seaweed 1-2 times per week to not exceed the amount of iodine allowed.
In countries like Japan, seaweed is a daily dish. The Japanese often eat seaweed with tofu, vegetables and drink soy milk. These foods contain substances that help to limit the iodine absorption of the thyroid, so even if the diet is high in seaweed, they do not have thyroid disease.
May have digestive problems
If your digestive system is weak, you should limit your intake of seaweed. That's because seaweed contains many carbohydrates that the digestive system cannot digest, and also reduces the bacteria in the intestinal tract. Besides seaweed also has a lot of fiber. Eating lots of fiber is good for your body, but if your digestive system is weak, this will make your digestive system work harder, causing indigestion.
May be contaminated with heavy metals
Seaweed has many beneficial minerals, but be aware that seaweed may also contain some heavy metals. Heavy metals can be contaminated with seaweed depending on the water source and the harvest place of each type.
But in general, all other seafood has a low risk of heavy metal contamination without affecting health. If you are still concerned, do not use seaweed or other seafood.
Seaweed is harvested in Korean waters quite safely. If in doubt, look for products from reputable companies whose products have been verified.
No matter how good food is, it's recommended to use it in a healthy fit. Hopefully, the article above has provided you with the necessary insights on how to use seaweed safely.
