Albert Szent-Gyorgyi, a Hungarian biochemist, is credited with discovering kaempferol, a type of flavonoid isolated from various plant sources, including apples, beans, broccoli, Brussels sprouts, cabbage, grapes, grapefruit, witch hazel, kale, endive,� tomatoes, strawberries, and tea in 1938. In the beginning, Gyorgyi was of the view that he had chanced upon a new vitamin and, hence, christened it as the vitamin P. Nevertheless, afterwards it was found that flavonoids are different from vitamins, as they are not absolutely necessary for the health of humans.
As discussed above, kaempferol is basically a phytochemical (a naturally occurring plant compound) present in numerous fruits and vegetables. From the point of science, kaempferol is a form of flavonoid called polyphenol possessing potent antioxidant attributes. This polyphenol has a yellow crystalline solid appearance and is also referred to as pelargidenolon, robigenin, rhamnolutein as well as swartziol. Several scientific studies have been undertaken on kaempferol. In fact, health experts are of the view that kaempferol possesses the aptitude to lessen the risks of several ailments and health disorders.
Kaempferol belongs to the flavonoid type which is also called flavonol. This flavonoid is present in several foods we consume regularly, such as apples, broccoli, Brussels sprout, onions, grapefruit, red wine, tea and several different types of berries. It has been found that this plant-based chemical has a protective action on our health. Findings of many studies have hinted that kaempferol shields us from heart diseases as well as cancer.
There are various types of flavonoids and many of them seem to have a beneficial or protective action on our health. The list of such flavonoids includes compounds like myricetin and quercetin. In fact, kaempferol was particularly identified to be a food element that reduced the chances of occurrence of incurable heart diseases, especially in women.
Kaempferol is also known to be a potent antioxidant and it aids in preventing oxidative harm to our cells and DNA. It is also believed that this mechanism of kaempferol helps this flavonoid to prevent the occurrence of arteriosclerosis. As this polyphenol prevents oxidative damage of the DNA, it also has the aptitude to protect us from cancer. This is mainly because kaempferol prevents the occurrence of mutations.
In vitro studies have revealed that kaempferol also helps to slow down the formation as well as growth of cancer cells. It has also been found that this natural plant compound is most effective when used together with another flavonoid called quercetin. It also appears that kaempferol makes the carcinogenic cells more receptive to anti-cancer medications, counting the drugs used in chemotherapy.
It has been found that consumption of tea and broccoli, both of which contain adequate amounts of this flavonoid, has led to reduced risks of ovarian cancer, especially in women who have entered their menopausal phase. In fact, it has been found that this result is explicit for kaempferol and not related to consumption of any other type of flavonoid. It seems that consumption of two cups (500 ml) of broccoli daily or four cups (1000 ml) of black or green tea every day is sufficient to obtain this health benefit of kaempferol.
It seems that kaempferol also possesses therapeutic properties that neutralize estrogen, converting it into a phytoestrogen. It is an indication of the fact that kaempferol has the ability to attach to estrogen receptors, thereby obstruct estrogen from binding. It has been found that binding of estrogen facilitates some types of breast cancer. In fact, it has also been found that some other phytoestrogens like daidzein and genistein too possess the aptitude to reduce the occurrence of breast cancer. Some studies have correlated kaempferol to reduced levels of breast cancer. However, it is really unfortunate that kaempferol is yet to receive its due recognition, as it is still not considered to be as valuable as some other phytoestrogens.
Supplements containing this flavonoid are available commercially at most health stores. Nevertheless, it is important to consult a physician prior to taking any kaempferol supplement. This is because use of natural compounds may result in an assortment of effects, for instance get in the way of metabolism of the prescription drugs or herbal remedies you might be using from before.
It may be noted that kaempferol is also often referred to as indigo yellow. This vivid yellow hue of the blossoms of the tropical trees Acacia longifolia and Acacia decurrens is attributed to this phytochemical. Although a yellow dye called indigo yellow is available commercially, the chemical composition of this dye is entirely different from kaempferol.
Kaempferol has a yellowish appearance after it is isolated from its plant source. It is a crystalline solid. It is categorized as a flavonoid, a substance that is beneficial for our health. In fact, this flavonoid facilitates the different functions of the cells in our body.
Kaempferol is a flavonoid form present in several vegetables and fruits and it is believed that consuming this nutrient is beneficial for our overall and optimal health. Kaempferol is branded as a potent antioxidant that aids in getting the body rid of the harmful free radicals, which are also responsible for development of cancer. Kaempferol primarily works to prevent oxidation damage to DNA, which, in turn, may harm the different other cells in our body. If the process of DNA oxidation in not thwarted, it may lead to an assortment of ailments, counting the awful disease cancer. Scientific studies and laboratory examinations have show that the presence of this particular flavonoid in the bloodstream, the cells that have already been affected by cancer become more receptive to anti-cancer drugs, especially the medications that are used in chemotherapy. In addition, kaempferol also puts off cell mutations, which are related to formation and growth of cancer.
Besides combating cancer, eating foods that are loaded with flavonoids like kaempferol may also aid in preventing cardiovascular diseases. This is one reason why several vegetables and foods are sold as foods that are beneficial for our heart's health.
Drinking tea and consuming broccoli is considered to be a healthy option, as they are rich in kaempferol content. As kaempferol is reputed for offering health benefits like prevention of cancer and protecting the heart from various diseases, consuming foods that are rich in this flavonoid is effective in helping people to obtain most favourable health and possibly also extending their lifespan. In fact, the various and vital health benefits offered by kaempferol also validate the use of this flavonoid in the form of a principle element in a variety of food preparations and health supplements.
In addition to being a very potent antioxidant, kaempferol also possesses anti-inflammatory attributes, which makes this flavonoid all the more valuable. The antioxidant actions of this flavonoid, called a polyphenol, put off cell oxidation and damage due to it. Thereby, kaempferol not only shields us from cancer, but also provides protection against various life-threatening heart ailments like arteriosclerosis. Findings of a number of scientific studies have revealed that incorporating elevated amounts of kaempferol helps to slow down the chances of developing cancer and heart ailments. Using a combination of kaempferol and another flavonoid called quercetin works more effectively in suppressing the carcinogenic cells. These two flavonoids - quercetin and kaempferol, are often used in anti-cancer medications, as they help to combat this deadly disease effectively when used together.
Apart from its anti-inflammatory and antioxidant actions, this polyphenol is also said to have anti-microbial, anti-viral and neuro-protective effects. Kaempferol is very effective in thwarting any damage to the brain, primarily owing to its anti-inflammatory as well as neuro-protective actions.
While kaempferol is not known to be responsible for any severe adverse affects, this polyphenol may possibly cause allergic reactions in sensitive people. Moreover, an overdose of kaempferol may prove to be counter-productive and even damaging in the case of pregnant women and nursing mothers. Therefore, it is essential to check with your physician prior to taking any supplement containing kaempferol.
Not much is known about the symptoms or adverse reactions of taking kaempferol in excessive dosage. Findings of a number of scientific researches have hinted that intake of this flavonoid in excessive amounts may cause various allergic reactions. At the same time, an overdose of kaempferol may also slow down the effect of other medicines as well as supplements you may already be taking. Despite all these, scientists are yet to identify the symptoms related to kaempferol overdose.
As kaempferol is not thought to be necessary for human health, scientists have not set any official recommended daily allowance (RDA) of this flavonoid. Nevertheless, findings of some studies hint that one should ideally intake anything between 10 mg and 12 mg kaempferol daily in order to obtain the above mentioned health benefits of this flavonoid.
