If so, you are going to learn about the strong scientific data and beneficial properties that make this unusual plant a valuable supplement to your diet.

Overview of black sapote

Diospyros digyna, commonly known as Black Sapote, Chocolate pudding Fruit, Chocolate Persimmon and Zapote Prieto in Spanish belongs to the Ebenaceae family and originates from Mexico. Nonetheless, it is found in the Philippines, South America, and a few other nations. It is rare in most other countries and is dispersed over Mexico and Central America.¹ There are edible and non-edible parts of the plant. The leaves and stem are also used for their health benefits but the fruit is the only edible part. The fruits are round and almost the size of an apple. The fruit's epicarp is smooth and green. The pericarp turns muddy green or brown as it ripens, while the epicarp turns olive green.²

There are high amounts of certain nutrients like Vitamin A and Vitamin C in Black Sapote. However, the fat content in it is recorded to be very low. This makes it a very good source of food. Potassium and iron are additional minerals that have been found in Black Sapote. Polyphenols and Carotenoids have also been identified in them.³ The polyphenols and carotenoids are two forms of compounds that give the Black Sapote the special properties of anti-inflammation. While most people use black sapotes for food, they are also traditionally used as medication to heal skin diseases and feverish ailments.

Diseases associated with inflammation

One intricate biological process is inflammation. Essentially, it is the body's way of eliminating some harmful stimuli and the impact they have on various bodily systems. Some of the stimuli that this mechanism looks to get rid of and resolve include but are not limited to pathogens, damaged cells and tissues, and irritants. This process is a defence mechanism and plays a very vital part in cellular processes. Like the saying goes, “too much of everything is bad”, as well excessive inflammation can cause many problems that are detrimental to the normal functioning of body systems.⁴ 

A number of signalling molecules, as well as processes involving the activation of cytokines, chemokines, and nuclear factors, are some of the primary molecular mechanisms causing inflammation. When these signalling molecules are activated, prostaglandins, leukotrienes, and reactive oxygen species are produced. These are the elements that turn excessive inflammation into a medical concern.⁵

Inflammation is classified as either acute or chronic. An acute kind of inflammation is one that develops quickly and is meant to go away quickly. Heat, swelling, pain, and loss of function at the location of damage are the notable characteristics of acute inflammation. Conversely, chronic inflammation persists for a longer amount of time. It is mostly caused by the body's inability to deal with a failed attempt of acute inflammation. Autoimmune conditions and persistent irritants could also potentially lead to this issue.⁶

Many diseases exhibit inflammation indicating that inflammation plays a role in the development and advancement of illnesses. The accumulation of plaque in the walls of arteries results in conditions, like heart attacks, strokes and other cardiovascular ailments. These arteries are eventually narrowed or hardened, causing these health implications. One of the elements linked to the formation of plaque in arteries is inflammation. 

It is understood that inflammation can impact insulin signaling pathways resulting in disruptions. The presence of cytokines can interfere with insulin signaling ultimately leading to insulin resistance in individuals with type 2 diabetes. Additionally, various chronic conditions such as sclerosis, lupus, rheumatoid arthritis, Crohn's disease, ulcerative colitis and some forms of cancer have been linked to inflammation.⁷

Bioactive compounds in black sapote and their potential anti-inflammatory mechanisms

Black Sapote is not just appreciated for its flavour. Also, the numerous bioactive elements it contains, may have positive effects on the health of individuals who enjoy it. Polyphenols, Flavonoids, and Carotenoids are some of the components in this fruit. 

Polyphenols are one of the compounds that can be found in plants. Their antioxidant properties are widely recognized. They essentially purify the system by scavenging reactive oxygen species, which is one of the products of inflammation.⁷ They then reduce the risk of getting inflammatory diseases and other diseases that are as a result of oxidative stress by a significant amount. They improve the ability of the immune system to appropriately respond to and effectively remove inflammatory stimuli. They have a particular impact on the functions of macrophages, natural killer cells, T-cells, and other immune cells that are beneficial to maintaining good health.⁸

Flavonoids are one of the subclassifications of polyphenols. Black Sapote is full of them. They are primarily instrumental in plant pigmenting but are also well known for their antioxidant, anti-inflammatory, and anti-carcinogenic properties. While there are many different kinds of flavonoids, quercetin, catechins, and anthocyanins are the ones that are most common in black sapote. Flavonoids are known to suppress pro-inflammatory mediators, including chemokines, lipoxygenase (LOX), cyclooxygenase (COX), and cytokines.⁹ Put another way, by inhibiting these mediators, they essentially reduce inflammation and the symptoms that go along with it. 

Also, carotenoids are another recognized plant pigmenting substance. Many fruits and vegetables that have red, yellow, and orange colours are known to be attributed to them. Beta-carotenes are the type of carotenoids that are present in black sapote. Although their antioxidant qualities are well recognized, they also act as precursor molecules for the synthesis of vitamin A. They are essential in enhancing immunological, skin, and eyesight functions.^9,10

Challenges and considerations

The most obvious challenge related to the use of Black Sapote is geographical limitations. As stated, the plant is native to Mexico and Central America. It is able to thrive in tropical and subtropical climates. This restricts its cultivation to the regions with suitable environmental conditions, making it difficult to be readily available globally. Efforts to grow them in different places different from their native areas will require careful management practices and commitment of resources such as climate, soil, and other factors which do not always assure success.¹¹

Growing Black Sapote is also labor intensive and requires knowledge of certain specific practices. Knowledge is needed on pest control, pruning, harvesting practices and other cultural practices in agriculture. Notably, the amount of polyphenols, flavonoids, and carotenoids in the fruit might vary depending on the environment, the quality of the soil, and time of harvesting. This indicates that variability can impact the consistency and efficacy of products from black sapote.¹²

While black sapote is generally considered safe, it is vital to investigate the potential side effects and contraindications of the plant. Some individuals could possibly experience allergic reactions or gastrointestinal discomfort from consuming the black sapote.¹³ Consuming black sapote with certain medications or health conditions must also be evaluated so as to prevent certain adverse complications.

Future research directions

Lack of extensive clinical trials is one of the most significant gaps in the current knowledge about black sapote’s health benefits. While in-vitro and in-vivo experiments in animals provide comprehensive preliminary data, human studies are essential to validate these findings. This makes it difficult to make a definite conclusion about the efficacy and safety of black sapote for anti-inflammatory benefits.

There is also the need for long-term safety studies to understand the potential chronic effects of regular consumption of black sapote. This, in turn, will investigate the potential long-term side effects of prolonged use of black sapote. Closing these gaps will contribute to the development of recommendations for the therapeutic and safe use of black sapote.

Summary

Diospyros digyna is commonly known as chocolate pudding fruit, or black sapote. It belongs to the Ebenaceae family. Mexico and Central America are the native origins of the plant. Black Sapote has been reported to be containing certain compounds. Some of these compounds include vitamin C, vitamin A, iron, potassium, polyphenols, flavonoids and carotenoid compounds. These compounds provide them with anti-oxidant and anti-inflammatory properties. While chronic inflammation is associated with long-term problems including diabetes, autoimmune disorders, cancer, and cardiovascular ailments; acute inflammation is a temporary state of inflammation. Black sapote's bioactive ingredients suppress proinflammatory mediators, regulate immunological responses, and neutralize reactive oxygen species. But there are particular difficulties in growing black sapote, as well as a dearth of knowledge on its adverse effects and limitations. Further studies should concentrate on the efficacy and safety of the plant in human trials so as to certify these findings.
