Figs: Nutrients, What Research Shows and Safety

The common fig is the fruit of Ficus carica, a tree in the mulberry family (Moraceae). The soft, seedy fruit is eaten fresh or dried. People eat figs for sweetness, fiber and minerals, and some for bowel regularity. This page keeps the food separate from supplements and from hype, and says plainly where the research is thin.

Read this first

• Figs are a normal food, but any food can cause an allergic reaction. For trouble breathing or swelling of the face or throat, call 911. See food allergy basics and emergency signs. Fig allergy has been described in people sensitised to the weeping fig houseplant (Ficus benjamina). [5]
• The milky sap of the fig tree can cause painful skin burns when skin is then exposed to sunlight. This is about handling the tree, not eating the fruit. [10][11]
• People with kidney disease, or who take medicines that raise blood potassium, should ask their clinician about potassium-rich foods in general. [13]
• Honest summary: small trials of fig syrup or fig paste suggest a possible effect on constipation, but the evidence is limited and the forms differ from fresh figs. No source we read shows that figs prevent or treat a disease.

What is in it (USDA values)

Source: USDA FoodData Central, SR Legacy, "Figs, raw" [1]. The USDA household portion is 1 large fig (2-1/2 inch diameter), 64 g; other USDA portions are 1 medium (50 g) and 1 small (40 g). Per-fig values are our own scaling of the USDA per-100 g figures. % Daily Value uses the FDA 2016 Daily Values; values vary with variety, ripeness and storage. Our USDA data file covers raw figs only, so dried figs are not shown here.

Figs contain plant compounds called polyphenols. In one 2026 lab analysis, anthocyanins (the red-purple pigments) were mainly in the peel, and peel had higher antioxidant capacity than pulp. [8] Another 2026 lab study found leaves and twigs richer in many compounds than the fruit. [9] These are laboratory measurements; none of the studies we read shows that the compounds in figs act this way in the human body.

What research says

Eaten as food vs taken as a supplement or extract. The constipation trials used syrup or paste, not whole fresh figs, and some mixed figs with walnut. [2][3] The diabetes work used leaf extract in animals, not the fruit. [12] Results from one form do not carry over to another. We did not read any trial of a fig capsule or powder.

How much is a normal serving

• The USDA household portions in our data are 1 large fig (64 g), 1 medium (50 g) and 1 small (40 g). [1] This is information, not a prescription.
• Official US cup-equivalents for fresh and dried fruit (MyPlate / Dietary Guidelines): Proper evidence not found in the sources we read, because we could not open those pages in full this round.
• Drying concentrates sugars, fiber and minerals: a 2025 lab study of fresh and sun-dried figs found this. [15] Dried figs therefore pack more sugar and energy into a small portion than fresh ones. See fresh, frozen and canned produce and fruit juice vs whole fruit.
• How cooking changes the nutrients in figs: Proper evidence not found in the sources we read.

Safety, allergy and medicines

• Allergy: a study of patients with clinical fig allergy found they reacted through sensitisation to airborne Ficus benjamina allergens, not to rubber latex, and heat destroyed most of the allergenicity of the extracts. [5] A 2020 case report described a child allergic to fresh fig with house dust mite sensitisation and negative latex tests; the authors suggested a link through plant enzymes. [6] Latex-fruit syndrome, in which people allergic to natural rubber react to some fruits, is described in a 2024 review, which does not list figs in its abstract. [7] So we cannot say figs are part of latex-fruit syndrome.
• Skin and sunlight: touching fig leaves or sap and then going into sun can cause blistering, burn-like skin reactions (phytophotodermatitis). Case reports describe this in people picking figs or pruning the tree. [10][11] This is about the tree, not eating the fruit. Wash sap off the skin and keep it out of the sun; a clinician should see a blistering reaction.
• Potassium, kidneys and medicines: MedlinePlus says fruits and vegetables are the richest sources of potassium and that people with poor kidney function should not eat too many potassium-rich foods; ACE inhibitors, ARBs and potassium-sparing diuretics can raise blood potassium. [13] Figs contain 232 mg per 100 g (USDA) [1], which is moderate. Anyone on these medicines or with kidney disease should ask a clinician, especially about dried figs, where potassium is more concentrated. See kidney disease, potassium and oxalates.
• Warfarin: USDA lists 4.7 µg of vitamin K per 100 g of raw figs [1]. We did not read a source that tells people on warfarin what to do about figs, so we make no claim. See foods and medicine interactions.
• Sugar: raw figs have 16.3 g of sugars per 100 g. [1] Dried figs are more concentrated [15]. People managing diabetes should ask their care team about portions.
• Sulphites in dried fruit: Proper evidence not found in the sources we read. Check the label if you are sensitive.
• Pregnancy: the fig-syrup trial was in pregnant women and reported effects on bowel movements only; we read no safety conclusions. [2] See foods in pregnancy.
• Fig leaf teas and sap products: the sap is phototoxic [10][11]; we did not read safety data on leaf teas.

Choosing, storing and food safety

• Choose fruit that is not bruised or damaged, and cut away bruised areas. [14]
• Keep perishable fresh produce in the refrigerator at 40°F or below. [14]
• Rinse under running water; do not use soap or produce wash. [14]
• Keep raw produce away from raw meat, poultry and seafood. [14]
