Oct 19, 2017


 

Autumn brings us so many gorgeous things! Have you already tried the Japanese favourite Autumn harvest, Ginkgo nuts (銀杏 Ginnan) ? They are so delicious that you might feel like eating them all day. However, you should not eat too much! Reason behind it is the 3 life threatening symptoms Ginkgo nuts can cause.

 

Ginkgo Nuts (銀杏 Ginnan) can be poison?

 

 

Autumn is my favourite time of year! It is breathtaking to see the street lined with Ginkgo trees (イチョウ)when all the leaves turn into yellow. I feel as if I was walking through a yellow tunnel!

Do you know Japanese people like eating Ginkgo nuts? Yes, that stinky one! They are actually delicious and quite nutritious that containing vitamin A,B,C, protein, iron and potassium. In China, they have been even used as a medicine.

However, let me warn you not to eat them too much because eating large quantity of Ginkgo can cause Ginkgotoxin poisoning!

 

 

What will happen when you eat Ginkgo too much?

 

Ginkgo nuts contain Ginkgotoxin (Methylpyridoxine), which impedes Vitamin B6 exhaustion. The lack of Vitamin B6 can cause these serious symptoms;

 

Vomiting and diarrhoea

They are the most common symptoms. The symptoms usually start appearing within 12 hours after eating Ginkgo nuts.

Difficulty breathing and loss of consciousness

Vomiting and diarrhoea is bad enough but it can go even worse. It can cause difficulty breathing, then loss of consciousness and in the worst case, shock which leads to death.

If you feel dizziness after eating Ginkgo nuts, go to E&A without hesitation!

Allergic reactions on your skin

Touching Ginkgo sometimes causes an allergic reaction. Signs of an allergic reaction to ginkgo may include rash, hives, itching, and facial or mouth swelling. If you touch them with bare hands, avoid touching other parts of your body and make sure to wash your hands immediately.

So, how much are we allowed to eat?

 

Generally, 40 pieces per day for an adult and 7 pieces per day for a child.

You might be relieved to hear that you can eat up to 40 pieces per day? Surely you don’t usually eat that much, do you?

But it is worth noting that 70 percent of the patients of Ginkgotoxin poisoning are children. The younger they are, the easier to be affected. So, you have to be very careful when you use Ginkgo nuts for children’s meal. A tiny quantity might cause poisoning. It is wise to avoid giving them to small children and babies.

My grandmother used to stop me eating Ginkgo nuts when I was a child. So, there was science behind it!
