Lemon peel is one of the most underrated foods in our daily diet. Most people tend to throw away the zest without thinking about its composition, although scientific studies show that it is safe to eat and contains a number of beneficial substances that can complement our daily diet.
According to Verywell Health, lemon peel is a high concentration of antioxidants. In particular, it contains vitamin C, D-limonene and the flavonoid hesperidin. These compounds help the body fight oxidative stress, support the immune system and can reduce the negative effects of free radicals. According to scientific publications, lemon peel often surpasses not only the pulp and juice, but also the skin of other citrus fruits in terms of antioxidant activity.
An important benefit of lemon peel is its fiber and mineral content. One tablespoon of zest has minimal calories, but contains pectin, a form of soluble fiber that promotes normal digestive function. In addition, the peel contains calcium, potassium, magnesium, and a significant portion of the daily requirement of vitamin C.
Some studies suggest that lemon peel may be beneficial for oral health. Extracts from the peel may inhibit the growth of bacteria that are linked to tooth decay and gum disease. Researchers also note the potential positive effects of lemon peel on the cardiovascular system. Antioxidants and fiber may help lower cholesterol and blood pressure, although more clinical studies are needed to draw definitive conclusions.
Laboratory experiments also demonstrate the antimicrobial properties of lemon peel. The substances contained in it are able to inhibit the growth of certain bacteria and fungi. At the same time, scientists emphasize that these results need to be confirmed in human studies.
Another area of research being explored is the potential role of lemon peel in cancer prevention. The antioxidants D-limonene and hesperidin have been linked to their ability to support normal cell growth. Some studies also suggest a possible link between citrus peel consumption and a reduced risk of certain cancers, but the evidence base is limited.
Experts advise washing lemons thoroughly before use to reduce the risk of pesticide residues. The zest can be added to drinks, desserts, sauces, marinades, fish, soups or stored in the refrigerator for several days. Such a simple ingredient can not only diversify the taste of dishes, but also bring additional health benefits.
