Introduction
Nestled in the heart of West Africa lies a humble berry with extraordinary powers: the miracle fruit (Synsepalum dulcificum). This small fruit packs a delightful surprise for both the person’s tastebuds and their overall well-being. It consists of a unique glycoprotein known as miraculin, a taste-altering agent that binds to tongue receptors, temporarily making sour foods taste sweet.1 Renowned for its culinary novelty, miracle fruit has found its way into kitchens worldwide, changing the way we perceive and enjoy acidic flavours without the need for added sugars.
However, the intrigue surrounding miracle fruit goes beyond its culinary applications. Recent scientific inquiry, demonstrated by a study featured in the International Journal of Molecular Sciences, suggests a deeper layer of potential health benefits. The research hints at its ability to lower cholesterol levels, a revelation with profound implications for cardiovascular wellness.1 High cholesterol stands as a formidable risk factor for heart disease, stroke, and other cardiac conditions. Incorporating miracle fruit into people’s diets could be promising for natural cholesterol management and overall heart health support.
Understanding cholesterol
Poor cholesterol management can have detrimental, life-long effects on a person’s health. These effects include inflammation within the arterial walls, exacerbating conditions such as atherosclerosis, and contributing to the development of other chronic diseases such as hypertension and diabetes.
High levels of LDL (low-density lipoprotein) cholesterol, often termed the "bad" cholesterol, contribute to the progression of atherosclerosis, a condition characterised by plaque buildup in the arteries. This accumulation of plaque narrows the arteries, preventing sufficient blood flow and increasing the risk of serious cardiovascular events such as major heart attacks, and blood clots that lead to strokes. Increased LDL cholesterol levels are also associated with endothelial dysfunction, reducing the functionality of the blood vessel lining and further impacting cardiovascular health.2 Increased low-density lipoprotein cholesterol (LDL-C) related cardiovascular disease is one of the leading causes of mortality and morbidity in Europe, accounting for 45% of all deaths, including 160,000 each year in the UK alone.2 The British Heart Foundation estimates that over half the adults in the UK are living with cholesterol levels that are higher than the national recommendations (<5 mmol/L) for total cholesterol (TC).
Conventional pharmaceutical treatments, such as statins, are most commonly prescribed to manage higher cholesterol levels, reducing LDL-C levels by approximately 20% on average.3 However, these treatments can come with a range of side effects, such as an increased risk of developing diabetes and certain muscle disorders.3 This has caused many to seek out non-drug-related cholesterol-lowering agents to manage their lifestyle better and avoid the side effects of conventional drug-based treatments.
Miracle fruit
Miracle fruit is a berry native to West Africa that has been used for centuries as a medicinal plant to manage various health conditions.4 The fruit is most commonly known for its fascinating taste-altering effects and has captured the curiosity of people worldwide, contributing to its growing popularity and commercialisation. It contains a unique glycoprotein called miraculin which binds to taste receptors, causing a taste-modifying effect. Historically it has been used as a sweetener or flavour enhancer, but in recent years it has been explored for its potential health benefits. Culturally, miracle fruit holds significance beyond its culinary applications. It has been used in ceremonial rituals and celebrations, reflecting its cultural importance and symbolic value within local communities.
Nutritionally, miracle fruit is rich in vitamins and minerals, making it a unique culinary ingredient and a potentially health-promoting food. It contains significant levels of vitamin C, which contributes to its health benefits.5 In addition to its taste-modifying and nutritional properties, miracle fruit exhibits various other interesting characteristics. It has a low caloric content, making it suitable for individuals seeking to manage their calorie intake. Research suggests that consuming miracle fruit may improve insulin sensitivity and glucose metabolism, potentially offering benefits for blood sugar control and overall metabolic health. The fruit shows potential applications for managing conditions such as diabetes and metabolic syndrome due to its effects on taste perception and glucose metabolism. Furthermore, miracle fruit exhibits antioxidant properties, attributed to its rich content of polyphenols and flavonoids. These antioxidants can help combat oxidative stress and inflammation, which are linked to the development of chronic diseases such as cardiovascular disease and various cancers. 5
Managing cholesterol with miracle fruit
Some of the health-promoting properties of miracle fruit being researched currently include enhancing insulin sensitivity (subsequently aiding in weight management), managing conditions such as diabetes and other metabolic syndromes, and aiding in the lowering of cholesterol levels. Cholesterol management is a critical aspect of cardiovascular health, as high levels of LDL cholesterol are associated with an increased risk of heart disease. One study investigated the effects of miracle fruit on lipid metabolism and cholesterol levels in mice. The researchers divided the mice into two groups – one group received a standard diet, while the other group received a diet supplemented with miracle fruit extract. After 4 weeks of dietary intervention, the researchers assessed various factors related to lipid metabolism and cholesterol levels.6
The results of the study showed several intriguing findings. The mice that received the miracle fruit extract supplementation exhibited significantly lower levels of total cholesterol and LDL cholesterol compared to the control group. This suggests that miracle fruit may have a beneficial effect on metabolising cholesterol, leading to a potential decrease in the risk of cardiovascular disease. Furthermore, the researchers observed that the mice supplemented with miracle fruit extract showed increased expression of genes involved in cholesterol metabolism in the liver. These genes were specifically related to cholesterol uptake, and the excretion of LDL was upregulated, indicating that miracle fruit may alter the total cholesterol levels through mechanisms involving hepatic (liver) lipid metabolism.6
In addition to its effects on cholesterol levels, miracle fruit supplementation was also associated with improvements in other metabolic processes. The mice in the miracle fruit group had lower levels of triglycerides, another type of lipid-associated with increased cardiovascular risk, as well as improved glucose tolerance compared to the control group. This could be beneficial for patients looking for potential cholesterol-lowering treatments without the risk of developing or exacerbating conditions such as diabetes. Overall, the findings of this study suggest that miracle fruit supplementation has potential benefits for cholesterol management and overall cardiovascular health.6 Further research in human populations is required to further validate these findings and explore the key mechanisms and underlying effects, including the optimal dosage and long-term safety of miracle fruit supplementation.
Incorporating miracle fruit into a balanced lifestyle
Incorporating miracle fruit into daily meals can be as simple as consuming the berry fresh or using the powder form as a natural sweetener in recipes. The recommended dosage and frequency of miracle fruit consumption can vary, but it is generally considered safe to consume in moderation for most people. Maintaining a balanced diet of nutrient-rich foods while incorporating miracle fruit will yield the best results in managing overall cholesterol intake.
Regular physical activity plays a crucial role in managing cholesterol levels, along with maintaining a healthy weight and overall cardiovascular health. Early results also indicate that miracle fruit shows potential in enhancing taste perception and making food more enjoyable for individuals undergoing chemotherapy, although additional research is needed to fully understand its effectiveness and how it could be utilised to support cancer patients' well-being throughout their treatment journey.7. Other lifestyle factors such as smoking, excessive alcohol consumption, and stress can also impact cholesterol levels and should be addressed for comprehensive management. Individuals with high cholesterol or other cardiovascular risk factors should consult with a healthcare professional before making significant dietary or lifestyle changes, including incorporating miracle fruit.
