Carrot
Karotte · (Daucus carota subsp. sativus)
Carrot family (Apiaceae)
Description
The carrot owes its vivid orange colour mainly to beta-carotene, which sits alongside alpha-carotene, potassium, vitamin K1 and pectin in the storage root harvested from summer through late autumn. A cooked, grated preparation of the root has been examined in clinical settings in connection with diarrhoeal complaints, plausibly linked to its high pectin content; folk tradition also held raw carrot juice to be beneficial for skin and eyesight. As a food, carrots are very safe — only very large, sustained intakes can cause a harmless, reversible yellowing of the skin known as carotenaemia. One important caution when foraging: wild carrot, the ancestor of the cultivated root, is easily confused with highly toxic Apiaceae such as poison hemlock or water hemlock, so uncertain finds should never be picked and eaten.
Raw carrots are one of the richest plant sources of provitamin A (beta-carotene). 100 g raw carrot supplies ~8350 µg beta-carotene, covering ~93 % of the recommended daily vitamin A intake. Eaten raw — grated, as sticks, or as juice — carrots are a staple in salads, crudités, and smoothies. The body converts beta-carotene to retinol on demand; excess beta-carotene is not converted to toxic vitamin A.
Cooked carrots are well tolerated and suitable for all age groups. Cooking breaks cell walls, increasing bioavailability of beta-carotene up to threefold compared with raw — especially when consumed with a small amount of fat (e.g. butter, oil). Carrots are steamed, braised, added to soups and stews, and used as weaning food for infants.
Carrot juice is a concentrated drink from freshly pressed carrots supplying beta-carotene, potassium, and vitamin C in high density. In nutritional tradition it is recommended as a tonic, for skin support (beta-carotene discussed as endogenous UV protection in studies), and as a general vitamin drink. Excessive intake (> 0.5 l/day over weeks) can cause harmless carotenaemia — orange-yellow skin tint, which fully reverses on reducing intake.
Coarsely grated raw carrots have been used in folk medicine for mild diarrhoea — especially in children. The effect is attributed to the high pectin and fibre content, which binds water in the gut and normalises stool consistency. The folk remedy 'grated carrot for diarrhoea' appears in German-language herbal literature since the 19th century. It is not medically standardised but is considered safe and used by parents as a first-response measure.
The 'Moro's carrot soup' is a long-boiled carrot preparation developed by paediatrician Ernst Moro (Heidelberg, c. 1908) to treat infantile diarrhoea. Boiling for 1.5 hours at 100 °C cleaves pectin chains, releasing short-chain oligogalacturonides. These 'Moro oligosaccharides' block intestinal mucosal receptors to which enterotoxin-producing bacteria (E. coli) and rotaviruses bind. Clinical studies from the 2000s (mainly Germany and Switzerland) confirmed significant reduction in duration and severity of diarrhoea in infants. The soup is now regarded as a well-documented complementary home remedy.

In folk medicine and traditional herbal practice, carrots have been associated since antiquity with good eyesight and healthy skin — a folk belief that has a real basis: vitamin A deficiency causes night blindness and dry mucous membranes, and carrots supply the provitamin A needed. The association 'carrots are good for the eyes' is widespread in everyday folk medicine and is medically correct in the context of deficiency — with adequate nutrition, additional beta-carotene intake confers no vision improvement.
Carrots are one of the world's most widely used vegetables, present in nearly every cuisine: raw as a snack and salad ingredient, cooked in soups, stews and sauces, fermented (e.g. kimchi variants), as infant weaning food (purée), in baked goods (carrot cake, Rüeblikuchen), and dried in seasoning blends. Their culinary value lies in mild sweetness (fructose, glucose, sucrose) and yellow-orange colour from carotenoid pigments.
Carrots are considered very safe. Very high sustained intake (> 0.5 l carrot juice daily over weeks, or very large amounts of raw carrots) can cause carotenaemia: a harmless orange-yellow discolouration of the skin (especially palms and soles), which fully and harmlessly resolves on reducing intake. WARNING WHEN FORAGING: Wild carrot (Daucus carota subsp. carota) and garden carrot may be confused with TOXIC Apiaceae — notably poison hemlock (Conium maculatum), water hemlock (Cicuta virosa), and hemlock water dropwort (Oenanthe crocata). When in doubt, do NOT forage — source from shops or your own garden. Rarely: contact allergy to carrot juice or raw carrots (quercetin and falcarinol sensitisation).
Carrots consumed in usual food amounts are considered completely safe in pregnancy and lactation. They are a valuable source of provitamin A and folate. Very large amounts of carrot juice (> 0.5 l/day sustained) are not recommended for general dietary balance reasons.
Carrots in food amounts are safe during lactation. Beta-carotene intake from carrot consumption is physiological and safe.
Carrots are one of the most popular and safest weaning vegetables for infants from the 5th–6th month. Steamed carrot purée is well tolerated. Avoid whole raw carrot pieces for young children (choking risk) — grate finely or cook instead. Moro's carrot soup possible from infancy (under medical guidance for diarrhoea).
Drug interactions
Vitamin-A-Präparate / Retinoide (Isotretinoin, Acitretin, Tretinoin)
With concurrent high-dose vitamin A supplements or systemic retinoids, additionally very high beta-carotene intake (e.g. > 0.5 l carrot juice daily) could theoretically contribute to accumulation. At normal food amounts there is no risk — dietary beta-carotene is regulated and not converted to toxic vitamin A levels by the body.
Contraindications
- Known allergy to carrots or other Apiaceae (cross-allergy with birch, celery, and spices possible — oral allergy syndrome).
Harvested part: root (summer-autumn)
- Time of day:
- Carrots can be harvested at any time of day. Early harvests (bunching carrots, May–July, depending on sowing in March–April) are tender and mild. Main harvest July–October, storage harvest October–November. Carrots tolerate light frost down to ~-4 °C and can remain in the bed into winter in loose, unfrozen soil.
- Drying:
- HARVEST: Harvest carrots 70–120 days after sowing depending on cultivar (fast varieties from 70 days, storage types 90–120 days). In loose soil lift by hand or loosen with a digging fork; in clay soil carefully loosen deeper with the fork. STORAGE: Cut tops immediately to 1–2 cm (otherwise foliage draws moisture from the root). In the refrigerator crisper a fresh carrot keeps 2–4 weeks. Optimal cellar storage: layered in moist sand or peat at 0–4 °C and high humidity (90–95 %) — storable for several months. Storage cultivars: 'Flakkeer', 'Rodelika', 'Rothild'. Do NOT store carrots with apples (ethylene gas from apples promotes bitterness).
- Storage:
- 6 months — 0–4 °C, high humidity 90–95 %, dark, in moist sand or perforated storage bags. Store separately from apples.
- Time of day:
- Carrot tops (carrot greens) can be used as a by-product of harvest or by targeted harvest of young plants. Young, light-coloured leaves are milder and aromatically nutty; older foliage becomes bitter and slightly rough. Uses: as a herb addition in pestos, smoothies, salads (in small amounts — bitter), as animal fodder (rabbits and guinea pigs enjoy them greatly).
- Drying:
- CARROT TOPS: Use fresh or dry at max. 35 °C and use as a seasoning herb. Do not eat large amounts of carrot tops as food — they contain furanocoumarins and alkaloids in higher concentrations than the root; safe in small amounts as a garnish or seasoning.
- Storage:
- 1 months — Fresh in refrigerator 2–3 days; dried in a sealed jar up to 3 months.
- Beta-CarotinVitaminContent: 0.06-0.12 %Root
Dominant carotenoid of carrots and the most important provitamin A in human nutrition. ~6000–8000 µg per 100 g raw carrot; bioavailability increases substantially with cooking and fat addition. Responsible for the characteristic orange colour. Antioxidant; converted in the body to retinol (vitamin A) as needed.
- Alpha-CarotinVitaminContent: 0.02-0.05 %Root
Second most abundant carotenoid in carrots, also provitamin A (~half the activity of beta-carotene). Alpha-carotene is associated with additive antioxidant effects and in epidemiological studies with a favourable health profile.
- Pectin (Pektine)PolysaccharideContent: 0.8-1.4 %Root
Main fibre fraction of the carrot root. Pectin swells in the intestine, binds water, and normalises stool consistency — the basis for folk use in diarrhoea. With prolonged heating (Moro's carrot soup) short-chain oligogalacturonides form, blocking pathogen receptors on the intestinal mucosa.
- Falcarinol (Polyacetylen)OtherContent: 0.002-0.005 %Root
Bioactive polyacetylene found in carrot roots, especially in the outer layer (periderm). Laboratory studies show cytotoxic properties against cancer cells; clinical relevance in humans not established. Can cause contact dermatitis with intensive skin contact with large amounts of raw carrots (rare).
- Dietary Fibre / Ballaststoffe (Gesamt)PolysaccharideContent: 2.8-3.0 %Root
Total dietary fibre (soluble + insoluble) of raw carrot. Contributes to satiety, gut health, and moderation of postprandial blood glucose rise (low glycaemic index despite sugar content). USDA FoodData: ~2.8 g/100 g.
- Kalium (Potassium)MineralContent: 0.32 %Root
Important macronutrient in carrots (~320 mg/100 g). Essential for nerve and muscle function and blood pressure regulation. Carrot juice is a potassium-rich beverage, relevant in low-potassium diets.
- Vitamin K1 (Phylloquinon)VitaminContent: 0.00013 %Root
Carrots supply moderate vitamin K1 (~13 µg/100 g, ~11 % DV). Vitamin K1 is essential for blood coagulation and bone metabolism. Persons on anticoagulant therapy (warfarin, phenprocoumon) should keep their overall vitamin K intake stable — occasional normal carrot consumption is unproblematic.
- Vitamin C (Ascorbinsäure)VitaminContent: 0.006 %Root
Raw carrots contain ~6 mg ascorbic acid/100 g (moderate, ~6–8 % DV). Vitamin C is heat-sensitive — up to 50 % lost during cooking. Contributes to overall antioxidant capacity and iron absorption.
