Chard, Swiss, boiled in unsalted water

Swiss chard is a leafy green vegetable. The figures here describe chard boiled in unsalted water. It provides vitamins and minerals, with small amounts of carbohydrate and protein and very little fat. Per 100g, it contains 728µg of vitamin A (retinol equivalent), 100µg of folate, 550mg of potassium and 0.45g of salt.

Vitamin A supports normal vision and immune function, while folate is needed for normal cell division and blood formation. Potassium helps nerves and muscles work normally. Although no salt is added during boiling, chard contains naturally occurring sodium, which is included in the salt figure. This is relevant when monitoring salt intake. Full nutrient figures are in the tables below.
