Lemon peel

Lemon peel is the outer rind of the lemon, including the coloured zest and white pith. The supplied data are from literature sources and do not specify a preparation method. It provides fibre, vitamin C and calcium: per 100g, it contains 11g of fibre, 130mg of vitamin C and 130mg of calcium.

Fibre supports normal bowel function, while vitamin C contributes to normal collagen formation and helps the body absorb iron from plant foods. Calcium is needed for normal bones and teeth. Lemon peel is usually eaten in small amounts, so its contribution depends on how much is used. Full nutrient figures are in the tables below.
