Most onion cultivars are about 89% water, 4% sugar, 1% protein, 2% fibre and 0.1% fat. They are high in vitamin C, vitamin B6 and folic acid and are a good source of dietary fibre. They are very low in fats and in sodium, and with an energy value of 166kJ (40 kcal) per 100 g (3.5 oz) serving, they can contribute their flavour to savoury dishes without raising the calorific content to any great extent.
Onions contain chemical compounds such as phenolics and flavonoids, that have potential anti-inflammatory, anti-cholesterol, anticancer and antioxidant properties. These include quercetin and its glycosides quercetin 3,4'-diglucoside and quercetin-4'-glucoside. There are considerable differences between different varieties in antioxidant content. Shallots have the highest level, six times the amount found in Vidalia onions, the variety with the smallest amount.
