Better cook the Onion and other vegetables

A friend likes to take raw Onion. Small amount such as 20 grams of raw onion a day is consider safe for the long run. Try to cook the rest if we try to consume more such as 250 grmas for each person in a day.
Other vegetable such as local product Sayoh Manis must be cut into small pieces and cook with 120 degrees and above for at least 10 minutes to get rid of Cyanide compound.
Yes ! Cyanide (poison)
Most of the plant contain Flavonoid, Tannin and many plant alkaloid... yes...plant may have aquired the ability to protect themselves against enemy such as insect and othe parasites( who ?)
Any way, be wise. treat nature with respect and take small amount of raw food ( must be clean, and remember that organic food contained lots of bacteria and organisms)
p/s Sayoh Cangkok Manis was shipped tp Taiwan and Hong Kong by containers daily in 1995. Special business men claimed that it helped people to slim down and achieved beautiful figure.(38,20,36 ???) 5 died after taken Sayoh Cangkok Manis blended juice raw. There are 200+ on dialysis due to kidney failure. Taiwan health authority arrested those business people who advertised that food( raw vegetable from KK, S, Mala..). Ok..wishing you good health
