Apricot Seeds - dangerous by combining these foods

I have been interested in the apricot seeds and cancer. I have been doing research and found this on a cancer research site from the UK. It states:

"If you do take laetrile by mouth, you should be sure to avoid eating raw almonds, crushed fruit stones or pips, celery, peaches, beansprouts, carrots or high doses of vitamin C. All these can increase the risk of cyanide poisoning if taken with laetrile."

If this is true a lot of us are taking high doses of Vitamin C!
