Health:
Lemons contain high levels of vitamin C, which can boost the immune system and help prevent illness. One lemon contains approximately 31 milligrams of vitamin C, which is about 51 percent of daily intake based on a 2,000-calorie diet, according to the Healthline website. The high vitamin C content can also improve iron absorption into the bloodstream.

The fiber in lemons, called pectin, can help with weight loss and reduce the risk of heart disease. Some studies show that eating fiber from citrus fruits reduces cholesterol levels in the bloodstream. Pectin can also reduce blood sugar levels by slowing the digestion of sugar and starches, according to the Healthline website. Most of the fiber is found in the pulp and peel of the lemon, so consuming the whole lemon will maximize its benefits.

Uses:
Due to their use in seasoning, baking and beverages, lemons are a versatile fruit. They can add a tart flavoring to marinades for chicken, fish or pork. The citric acid in lemons adds this flavor to many desserts, such as pies, cookies, bars and marmalade.

A slice of lemon in water can enhance the taste and encourage people to drink more of it while increasing vitamin C intake, according to the Healthline website.

When applied directly to the skin, lemons can also serve as toner when mixed with a little water or when made into a skin-brightening face mask. Vitamin C plays a role in collagen production, which can improve skin elasticity and repair damaged skin, according to an article from Oregon State University website.
