In addition, vitamin A helps mucous membranes and skin be powerful barriers to bacteria and viruses. Thus it is essential for good vision by reducing the risk of eye infections and associated ailments.

Studies suggest that it plays a role in curbing age-related macular degeneration (AMD) and vision loss. Consuming grapefruit can decrease the chances of progressing to AMD by 25%.

Consuming grapefruit reduces the risk of developing kidney stones. This miracle fruit contains citric acid that helps diminish the formation of calcium oxalate kidney stones.

The waste materials in our body normally get metabolised and filtered through the kidneys, and passed through urine.

Nevertheless, if they concentrate on the kidneys, they form stones. Some may cause a blockage in the urinary tract leading to pain and urine retention. Kidney stones generally are calcium oxalate stones. Citric acid, found in grapefruit, effectively prevents them by binding with calcium in the kidneys and flushing it out of the body. However, citric acid increases the volume and pH of urine, which proves to be an unfavourable condition in the formation of kidney stones.
