Introduction 

Kidney health is essential for overall well-being, as kidneys play a crucial role in filtering out unwanted substances from the body. Therefore, it is vital to ensure that they work to the best of their ability. Diet, in particular, plays an important factor in ensuring that the kidney is maintained in good condition. Mangoes are tropical fruits packed with nutrients and antioxidants which are beneficial for kidney health. This informative article explores the benefits of mangoes, especially regarding kidney health. 

Importance of kidney health

Kidneys are two important bean-shaped organs responsible for excreting waste products, regulating electrolytes, and maintaining a healthy acid-base balance. The size of our kidneys varies from person to person and are roughly the size of a closed fist and weigh between 150-200 grams or 120-135 grams for males and females, respectively.¹ Leading a healthy lifestyle can contribute to good kidney health preventing kidney diseases including chronic kidney disease (CKD).² CKD can lead to gradual loss of kidney function, leading to renal replacement therapy, dialysis, or kidney transplantation.³

Diet contributes to healthy kidneys by providing energy, preventing infections or kidney diseases, reducing muscle loss, and contributing to a healthy weight. By incorporating foods rich in nutrients including protein, sodium, potassium, phosphorus and calcium into your diet, your kidney health will drastically improve. One such beneficial fruit is the mango.² 

About mango

Mangoes, also known by their family name Mangifera indica, are tropical fruits which originated in India over 5000 years ago. Mangoes are also sometimes referred to as stone fruits as it is composed of an outer skin that covers the edible yellow portion of the fruit surrounding a seed in the shape of a stone. There are many different types of mangoes which grow in places such as the Middle East, East Africa and South America. The diversity in climates and growth conditions results in different types of mangoes.⁴

Hydration and electrolyte balance 

Maintaining good kidney health requires proper hydration to ensure optimal blood flow. Mangoes have a high water content and, therefore are good for hydrating the kidneys. Another key function of kidneys is to regulate electrolyte balance. The high potassium content in mangoes helps regulate electrolyte balance, including sodium and magnesium levels.⁶

Antioxidant and anti-inflammatory properties 

Mangoes are rich in antioxidants, thanks to high levels of vitamins A and C and phytochemicals like beta-carotene and flavonoids. Consuming mangoes and these chemicals, protects the kidney from damage, especially from free radical damage and inflammation. In addition, this also offers protection from the development and progression of kidney disease.⁶

Blood pressure regulation 

High blood pressure is a common trigger for kidney damage. The potassium and magnesium in mangoes regulate blood pressure by counteracting sodium, which contributes to higher blood pressure and improves blood flow. Mangoes, along with many other vegetables help regulate blood pressure levels resulting in a reduction of kidney diseases and problems.⁶
