  • Calories: 29
  • Water: 89%
  • Protein: 1.1 grams
  • Carb s: 9.3 grams
  • Sugar: 2.5 grams

The main components of the carbohydrates found in lemons include fibers and simple sugars including sucrose, fructose, and glucose (2).


Pectin is primarily found in lemon s.

By delaying the digestion of sugar and starch, soluble fibers such as pectin can reduce blood sugar levels (3).

Dietary fibers have been connected to several health advantages and are a crucial component of a balanced diet (3, 4).


About 10% of the carbohydrates in lemon s are made up primarily of simple sugars and soluble fibers. Pectin, the primary fiber in them, has the potential to reduce blood sugar levels.

Vitamins and minerals

Numerous vitamins and minerals can be found in lemon s.

  • Vitamin C: Vitamin C is a necessary antioxidant and vitamin that supports healthy skin and the immune system (5, 6).
  • Potassium: Consuming a lot of potassium-rich food can improve heart health and reduce blood pressure (7).
  • Vitamin B6: B6, a family of linked vitamins, helps the body turn food into energy.

Other plant compounds

Plant compounds are naturally occurring bioactive molecules that have significant positive effects on health .

Citrus fruits, such as lemons, contain plant chemicals that may be beneficial in reducing inflammation, cancer, and cardiovascular disease (8, 9, 10).

The primary plant components in lemon s are as follows:

  • Hesperidin: By strengthening your blood vessels and preventing atherosclerosis, or the accumulation of fatty deposits (plaque) inside your arteries, this antioxidant may benefit you (11, 12).
  • Diosmin: Diosmin, an antioxidant included in several medications that impact the circulatory system, lessens chronic blood vessel inflammation and enhances muscular tone (13).
  • Eriocitrin: Lemon juice and peel contain this antioxidant (13, 14).
  • D-limonene: D-limonene, which is mostly present in the peel, is the primary ingredient in lemon essential oils and gives lemons their unique scent. When taken alone, it can help with reflux and heartburn (15).

For optimal benefits, it is advised to consume the entire fruit, omitting the peel, as many of the plant chemicals included in lemons are not present in significant concentrations in lemon juice (16, 17).

Heart health

A higher risk of stroke is also linked to low blood levels of vitamin C, particularly in those who are overweight or have high blood pressure (21, 22).

Consuming citrus fruits' separated fibers has been demonstrated to lower blood cholesterol levels, and lemons' essential oils can prevent the oxidation of LDL (bad) cholesterol particles (23, 24).

While lemons are a wonderful source of vitamin C and citric acid, which might improve the absorption of iron from other foods, they only contain modest levels of iron (33, 34).

Lemons may aid in the prevention of anemia because they improve the body's ability to absorb iron from meals.


Lemons have the potential to lower the risk of breast cancer among other cancers. Plant substances like d-limonene and hesperidin are assumed to be the cause of this (35, 36, 37, 38, 39, 40, 41, 42).
