Lemons are rich in beneficial nutrients. This fruit is low in calories, with only 29 calories per 100 grams, which is one of the lowest among citrus fruits. Lemons contain no saturated fat or cholesterol, but they are rich in dietary fiber (7. .36%）。Its sour taste is due to citric acid, which contains up to 8% citric acid in its juice. Citric acid is a natural preservative that aids digestion.
Most studies have found that citric acid is very helpful in dissolving stones. Lemons, like other citrus fruits, are outstanding** for ascorbic acid, providing about 88% of the recommended daily intake. Ascorbic acid, or vitamin C, is a powerful water-soluble natural antioxidant. This vitamin helps prevent scurvy. In addition, consuming foods rich in vitamin C helps the body fight infectious agents and remove harmful, pro-inflammatory free radicals from the blood. Lemons, like oranges, contain a variety of phytochemicals. Hesperetin and naringenin are common flavonoid glycosides found in citrus fruits.
Naringenin has been found to have bioactive effects on human health, with antioxidant, free radical scavenging, anti-inflammatory, and immune system modulation effects. In in vitro studies, the substance has also been shown to reduce oxidative damage to DNA in cells. In addition, lemons contain trace amounts of vitamin A and other flavonoid antioxidants such as - and - carotene, -carotenoids, zeaxanthin, and lutein. These compounds are known to have antioxidant properties. Vitamin A is essential for maintaining healthy mucous membranes and **, as well as for vision. Consuming natural fruits rich in flavonoids can help protect the body from disease.
The total redox capacity (ORAC value) of 100 grams of fresh lemon juice is 1225 micromolar TE (Trox's equivalent), which measures its antioxidant strength. Lemons are also an excellent source of B vitamins** such as pantothenic acid, pyridoxine and folic acid. These vitamins are essential for the body because the body needs to replenish them from the outside. Lemons are also rich in minerals such as iron, copper, potassium, and calcium. Potassium is an important component of cells and body fluids and helps control heart rate and blood pressure.
