Foods that become toxic when eaten with seaweed

For lunch, I like broccoli.

Seaweed stem haha

It's really delicious if you dip it in the beginning.

The thicker parts of the seaweed stems are good to eat even with rice.

It's a winter delicacy, and seaweed is also said to be good for blood circulation.

Today, seaweed soup happened to be served as well.

I think I ate a lot of seaweed.

So that's why mom doesn't put green onions in the seaweed soup.

Please do not eat it because it is said to interfere with calcium absorption.
