One cup of chopped contains 64 kcals. When sliced, calories shrink to 46.
One Tablespoon of raw white onion contains about 4 kcals.
A large onion is equal to about 1 cup of chopped and contains 60 calories. A medium size onion measures about two and one-half inches in diameter and contains about 45 kcals.
Quercetin in Onions
Quercetin holds antioxidant and anti-inflammatory powers; it is a flavonoid found in the onion - all varieties of onions. If it also found in red wine, berries, apples, grapes, broccoli, citrus fruits, cherries, capers, green tea, Buckwheat tea, Ginkgo biloba, St. John's wort and American elder. Quercetin also contains anti-hypertensive properties.
Quercetin can be purchased in a supplement and is used by some individuals for the following conditions: as a cancer preventive, to combat diabetes, to combat cataracts, schizophrenia, to fight inflammation, gout, to ward off or combat viral and bacterial infections, peptic ulcers, asthma, chronic fatigue syndrome, enhancement of endurance - generally for athletes.
Side effects may occur, some of which can be serious. They include the following:
Taken Orally: headache, numbness and tingling.
Intravenously: shortness of breath or breathing difficulties, nausea, vomiting, kidney damage in amounts exceeding 945 milligrams.
Taking more than one gram daily can cause kidney damage.
Sauteed Increase Calories, Decreases Many Nutritional Elements
When oil, butter or any type of fat is added to natural food, the caloric value will of course 'naturally' increase. Heat will also produce a reduction in many of the essential vitamins and nutrients contained in the natural food.
Caramelized onions are a popular dish - and actually quite easy to prepare. When I prepare them, I use a very simple cooking method which doesn't require a long cooking time.
Ingredients for Caramelized Onions
1 cup of sliced white onion
1 Tablespoon of white sugar
Salt as desired
I cook the onion until it is translucent, then sprinkle on the sugar. They caramelize quite quickly - and have received rave reviews from guests. However, this recipe reduces the nutritional value of the onion. It also increases the sugar content. But this is still a great recipe to enjoy occasionally.
