  • Dishes prepared with onion along with other combination spices and items are delicious and have a specific flavour which is liked by the people across the continents and that is one main reason of its popularity. This is the taste part of the dishes prepared with onion. At the same time onions are important from dietary point of view as they also provide important nutrients and health-promoting phytochemicals. Another good thing with onions is that they contain vitamin C, dietary fiber, folic acid, calcium and iron.

    There are many factors which make onion a must for inclusion in our foods and some of those are that they contain no fats, high in dietary fibre, have a high protein quality, low in sodium etc. In addition to that onions also contain antioxidants which are the crucial compounds which help in slowing down of oxidative processes in the body. These processes are responsible for the cell damage as well as tissue weakening. Research has shown that onions contain the above mentioned antioxidant compound called quercetin which belongs to the group of flavonoid, a type of antioxidants. There are also some research which indicate the contribution of onion in regeneration of vitamin E in the body, inactivating the harmful effect of metal ions, elimination of free radicals etc.

    One interesting thing to note here is that we can get quercetin from other sources like apples we eat and tea we drink. But the absorption of quercetin in the human body from onions is much more than these other sources.

    One more thing in this context is that though onions have certain health benefits but it does not mean that we have to take them in plenty. No, we should not. We have to take them in a normal way as we are taking them in vegetables and other dishes. Body has a limit to absorb the antioxidants from the natural sources and excess amount of them in the blood may not be of any added benefit. So we have to consume the natural things in moderation only.
