It is true that there are advantages of onions. But there are certain things that most if us do not know. There are some ill effects of onions as well.
1. Latex and sulphur are contained in onions.
2. You get tears when cutting the onion because of sulpher in it.
3. The PH of the blood can be reduced because of onions.
4. Can prevent correct absorption of drugs.
Not entirely convinced by this list !
I'm happy to go along with the sulphur content of onions, but on what authority do you base your claim that they also contain latex ? Also bear in mind that some authorities argue that the sulphur content can be beneficial in combating the formation of cancer cells, reducing hypertension and assisting in the regeneration of hair follicles.
I'd also be interested to know on what authority you base claims 3 & 4 : I'm all in favour of keeping us curry chefs informed of the risks involved, but unsubstantiated claims can be more of a hindrance than a help.
