Why we don't use copper vessels for cooking ?

 In ancient India , people were using copper utensils for cooking . But nowadays we don't use . Why ?

There is an interesting story behind this . During last century , Indians were using copper utensils for cooking . Children who had food often fell ill . Nobody came to know about the cause .

Finally we discovered that this illness was due to consumption of copper . The copper particles found in more than usual amount getting accumulated in liver .

What actually happened was Indian mothers used to heat the milk in copper utensils . When milk was boiled for the first time , small amount of copper got mixed with milk .

All Indian mothers have the habit of using the same milk which was bought from the shop in the morning through out the day . So in the above said case also , milk was heated again and again and was given to children for drinking .

Though small amount of copper got mixed with milk whenever milk was heated , these copper particles started to get accumulated in human liver .

It is bad to have anything in excess . The accumulated copper in liver was the cause of illness children were facing . But it was not the food poisoning .

That's why nowadays we don't use copper vessels for cooking .
