Kumquats: What They Are, What They Are Good For, and How to Eat Them


Kumquats are small citrus fruits that are acidic, tart, and slightly sweet. They are small orange-flavored fruits that are high in vitamin C and fibre. They also include trace levels of iron, B complex vitamins, manganese, copper, and calcium.

Furthermore, the edible seeds of kumquats contain beneficial lipids such as omega-3 fatty acids. They also have a high water content. This makes them an ideal and convenient snack for quick energy and hydration.

The term kumquat is derived from a Chinese word that means “golden mandarin orange.” These little citrus fruits originated in China and are now grown in a number of countries, including India and Japan. Kumquats are more resistant to severe environmental conditions than oranges.

Kumquats offer anti-inflammatory, antioxidant, and immune-boosting effects. They may also help with gastrointestinal issues and maintain a healthy weight due to their high fibre content.

Kumquat peel and seeds are both edible. You can, however, remove it if necessary. Kumquats are used in a variety of recipes, including salads, chutneys, marmalades, sandwiches, candies, and many others.

Kumquats of Various Varieties

Kumquats come in six different types. These variants differ in terms of colour, flavour, and shape.

Kumquat Meiwa

This kumquat cultivar is also oval in shape. It does, however, have more seeds than the other varieties.

Kumquat from Hong Kong

Kumquats are complex carbohydrates because they include a fair quantity of fibre. As a result, they take longer to move through the gut since our digestive enzymes cannot break them down. As a result, you will feel fuller for longer. They suppress cravings, avoiding weight gain.

Kumquats have a lot of soluble fibre. Soluble fibre is well-known for its ability to prevent diarrhoea. It collects extra water from the intestines and condenses it into a gel-like material.

If you are experiencing frequent bouts of diarrhoea, eat a handful of kumquats. Furthermore, research suggest that fibre helps to reduce cholesterol in the body by excreting it through the faeces.

Functions as an Antioxidant

Kumquats are high in antioxidant vitamins such as vitamin A and vitamin C. Excessive levels of free radicals can cause cell damage. Kumquats’ antioxidants may help to minimise oxidative stress generated by free radicals in our body. So drink a glass of kumquat juice to get rid of the toxins in your body!

Kumquat Health Benefits

Anti-Inflammatory Action

When a hazardous pathogen is present in the body, our immune system responds by destroying the infection. Inflammation is the name given to this response.

It is most common in arthritis, inflammatory bowel disease, asthma, diabetes, autoimmune illnesses, heart difficulties, and neurological diseases. If the inflammation worsens, cell death and organ damage may occur.

Kumquats contain a variety of flavonoids, including kaempferol, luteolin, hesperidin, quercetin, C-glycoside, and others. C-glycoside has been shown in a few trials to have anti-inflammatory effects. It accomplishes this by lowering the immune system’s inflammatory response and the creation of damaging free radicals.

Antibacterial Action

According to one study, the oil derived from the peel of kumquats may have antimicrobial effects. As a result, it may inhibit the growth of various dangerous germs that grow on food, such as bacteria and fungi.

Because of its antibacterial properties, it may be useful in extending the shelf life of goods by reducing microbial development.

Enhances Eye Health

Kumquats have some vitamin A in the form of beta carotene. It’s one of eleven carotenoids found in kumquats. Carotenoids such as beta carotene, zeaxanthin, and lutein have been shown in numerous studies to benefit eye health.

Rhodopsin is found in our eyes. It is a protein molecule that allows us to see in low-light situations. Inadequate rhodopsin production, on the other hand, can result in night blindness. Vitamin A is required for the synthesis of rhodopsin. Kumquats contain a decent quantity of vitamin A, which is important for maintaining healthy eyesight.

Antioxidant Action

Kumquats have a high vitamin C content. The antioxidant properties of vitamin C are widely established. Furthermore, they aid in the reduction of oxidative stress induced by free radicals.

Free radicals are waste products produced in the body as a result of normal metabolic operations, exposure to environmental pollutants, and so on. Excessive levels of free radicals in the body can harm cells and organs. They can cause cancer, Alzheimer’s disease, heart disease, diabetes, and other diseases.

According to research, the vitamin C found in kumquats may lower the risk of various diseases by reducing the generation of free radicals in the body.

Mood Disorders May Be Regulated

Some research suggests that eating foods high in vitamin C may help with stress, mood, and sleep. It works by having an antidepressant-like effect and aids in the improvement of mental health by lowering the risk of anxiety, depression, and stress. However, the precise mechanism by which it improves sleep remains unknown.

Enhances Bone Health

Calcium is required by our bodies to develop and maintain healthy teeth and bones. As a result, a lack of calcium-rich foods during the key growth phases of life can result in a variety of illnesses such as short stature, dental caries, osteoporosis, and so on.

Vitamin C is also essential for bone growth. Furthermore, vitamin C aids in the synthesis of collagen. Adequate levels of this vitamin can thus promote skin and bone health.

Kumquats have a high calcium and vitamin C content. According to research, vitamin C may help prevent bone illnesses such as osteoporosis. By pulling calcium from the bones, acidic meals may raise the risk of bone diseases. Kumquats, as alkaline fruits, lower the chance of developing osteoporosis.

Enhances Immunity

The immune system is made up of a variety of cells such as macrophages, lymphocytes, natural killer cells, and so on. They are critical for disease prevention caused by several types of bacteria and viruses. They function by targeting and killing germs that infiltrate our bodies, causing inflammation.

According to one study, the antioxidants beta-cryptoxanthin and L-limonene found in kumquats may boost immunity. Furthermore, they function by increasing the activity of natural killer cells and decreasing metabolic stress in the body.

Anticancer Properties

According to study, apigenin, a type of flavonoid found in kumquats, may help prevent the development of cancer. Cancer produces unregulated cell multiplication and DNA alterations. Apigenin may affect on cancer cells by causing cell death, which prevents them from developing and spreading to other cells.

Prevents Obesity and Weight Gain

Poncirin, another flavonoid found in kumquats, may have an important role in obesity prevention. Poncirin may minimise the risk of weight gain by blocking the development of new fat cells in the body, according to one study.

Additionally, they are high in fibre. They keep you feeling fuller for longer because of their delayed passage through the digestive tract. They suppress hunger and the desire to eat unhealthy snacks.

Improves Gut Health

Kumquats have a good level of dietary fibre. Fibre goes through the digestive tract undigested by the enzymes produced in our stomach.

Furthermore, they are fermented in the stomach and serve as food for the beneficial bacteria that live there. They improve intestinal health and immunity in general. Furthermore, the soluble fibre included in these fruits may aid in the reduction of diarrhoea.

Prevents cardiovascular disease

Heart disease is caused by artery obstruction caused by high cholesterol levels in the body. It can lead to a stroke, excessive blood pressure, or heart failure. However, research has indicated that the flavonoids, fibre, vitamin C, and A contained in kumquats may help to prevent fat formation in the arteries. As a result, it lowers the overall risk of heart disease.

The fibre in kumquats may aid in the reduction of cholesterol levels by increasing its excretion through the faeces.

Enhances Blood Sugar Control

Maintaining proper blood glucose levels is critical in diabetics. Diabetes that is not well-controlled can lead to a variety of problems such as foot ulcers, retinopathy, and so on. As a result, persons with diabetes should consume low glycemic index fruits to avoid abrupt jumps in blood glucose levels after a meal.

Kumquats are low in sugar. As a result, they have a low glycemic index and are ideal for diabetics. Furthermore, due to their high fibre content, kumquats may minimise the odds of blood sugar increases after a meal, according to one study.
