Regular consumption of grapefruit can help prevent insulin resistance, which can cause diabetes.

Insulin resistance occurs when the cells stop responding to insulin. In one study, subjects who ate half of a fresh grapefruit before a meal significantly reduced both insulin levels and insulin resistance compared with the group that did not eat grapefruit (19).

What's more, eating fruit is generally associated with better blood sugar control and a reduced risk of type 2 diabetes.
Grapefruit contains a number of different antioxidants that have many health benefits, including a reduced risk of several diseases (33).

Antioxidants protect cells from damage caused by free radicals, which are unstable molecules that can cause harmful reactions in the body (34).Here is an overview of the most important antioxidants in grapefruit:

Vitamin C: A powerful water-soluble antioxidant with high levels in grapefruit. It may protect cells from damage, which often leads to heart disease and cancer.

Beta-carotene: It is converted to vitamin A in the body and is believed to help reduce the risk of chronic diseases, including heart disease, cancer and eye-related disorders such as macular degeneration.

Lycopene: Known for its ability to prevent the growth of certain types of cancer, especially prostate cancer. It may also slow tumor growth and reduce the side effects of conventional cancer treatments.

Flavanones: Their anti-inflammatory properties are believed to lower blood pressure and cholesterol, and reduce the risk of heart disease. Consuming grapefruit can reduce the risk of developing kidney stones, which result from the accumulation of waste products in the kidneys. The most common type of kidney stone is calcium oxalate stone. Citric acid, an organic acid found in grapefruit may work to prevent them from binding to calcium in the kidneys and eliminate it from the body.

Furthermore, citric acid has the ability to increase urine concentration and pH, creating a less conducive environment for the formation of kidney stones.
