Lemons: Health Benefits, Nutritional Information

Lemons first achieved their healthy claim to fame onboard the ships of early explorers to help treat scurvy , a then-common disease among the sailors.

In 1747, James Lind found that lemons and oranges were extremely effective at treated the disease, which we know was caused by a vitamin C deficiency from months at sea without any fresh produce.

Lemons are rarely consumed as a stand-alone fruit due to their intense sour flavor but are extremely popular when used in smaller quantities and in combination with herbs and spices to lend a wonderful and dynamic flavor to many sauces, salad dressings, marinades, drinks and desserts.

This MNT Knowledge Center feature is part of a collection of articles on the health benefits of popular foods. It provides a nutritional breakdown of lemons and an in-depth look at their possible health benefits, how to incorporate more lemons into your diet and any potential health risks of consuming lemons.

Possible health benefits of lemons

Consuming fruits and vegetables of all kinds has long been associated with a reduced risk of many lifestyle-related health conditions. Lets take a look at the possible benefits of consuming lemons.

Lowering stroke risk

Lemons have an intense sour flavor but are popular when used in combination with herbs and spices for many sauces, salad dressings, marinades, drinks and desserts.

According to the American Heart Association, eating higher amounts of citrus fruits may lower ischemic stroke risk for women. Those who ate the highest amounts of citrus had a 19% lower risk of ischemic stroke than women who consumed the least.¹

Combating cancer

As an excellent source of the powerful antioxidant vitamin C, lemons and lemon juice can help fight the formation of free radicals known to cause cancer.

Maintaining a healthy complexion

The antioxidant vitamin C, when eaten in its natural form or applied topically, can help to fight skin damage caused by the sun and pollution, reduce wrinkles and improve overall skin texture. Vitamin C plays a vital role in the formation of collagen, the support system of your skin.

Preventing asthma

The risks for developing asthma are lower in people who consume a high amount of certain nutrients, one of these being vitamin C.

Increasing iron absorption

Iron deficiency is one of the most common nutrient deficiencies in developed countries and a leading cause of anemia. Pairing foods that are high in vitamin C with foods that are iron-rich will maximize the body's ability to absorb iron. For example, squeeze lemon juice atop a salad with spinach and chickpeas (both a good source of iron).

Boosting the immune system

Foods that are high in vitamin C and other antioxidants can help the immune system battle germs that cause a cold or flu. Maintaining a healthy diet high in fruits and vegetables is especially important during the winter months when physical activity levels tend to drop.

More benefits

Consumption of fruits and vegetables of all kinds has long been associated with a reduced risk of many adverse health conditions. Many studies have suggested that increasing consumption of plant foods like lemons decreases the risk ofobesity, diabetes, heart disease and overall mortality while promoting a healthy complexion, increased energy, and overall lower weight.
