Kumquats are very small citrus fruits that can resemble a tangerine. They’re exotic in nature and have many beneficial properties for the body. They were originally cultivated in China and stand out because the whole fruit is edible, even the skin.

Here we’ll discuss all the benefits of consuming this food. Introduced in the context of a balanced diet they have many assets. However, they aren’t easy to obtain, as they’re rare fruits in Western countries.

Nutritional properties of kumquats

When talking about the nutritional value of kumquats, we must highlight its low caloric intake of only 71 kilocalories per 100 grams (4 oz). This is because 80% of the kumquat is made up of water. Among the macronutrients, the presence of carbohydrates stands out, specifically simple sugars, with 15.9 grams per 100 grams of fruit. Proteins and fats are practically residual in this case.

However, the situation changes when it comes to micronutrients. It contains significant amounts of vitamin C, up to 43 milligrams. At the same time, it has phytonutrients with antioxidant capacity that neutralize the production of free radicals. It also contains fiber, which allows a more gradual absorption of the sugars it provides.

2. Reduced constipation

Surely you have already heard that fiber intake is key to combating constipation. This substance has been shown to be able to increase the volume of the fecal bolus, stimulating the mechanoreceptors of the intestine and generating a more powerful intestinal peristalsis. In this way, the stools pass more efficiently through the digestive tract.

At the same time, this same fiber can create a feeling of satiety, which reduces the risk of snacking on unhealthy products between meals. Thus, a hypocaloric diet is easier to plan.

3. Effective against anemia

Kumquats’ vitamin C content helps maximize iron absorption at an intestinal level, according to research published in the Asia Pacific Journal of Clinical Nutrition . In this way, it reduces the risk of developing anemia, a pathology that causes extreme fatigue and tiredness, and which occurs as a result of an inefficient intake of the aforementioned mineral.

How to eat them?

Kumquats can be eaten naturally, including the skin that gives it a sweet taste, or by preparing products such as jams or jellies, in which you can take advantage of the bitter touch of the pulp. It’s also possible to prepare meat sauces with this food. It can even be used in smoothies to maximize their nutritional value.
