Health Benefits Of Grapefruit

Promotes Appetite Control

As mentioned, grapefruits contain high amounts of fiber (about two grams in half of each medium-sized fruit). Research on fiber concludes, specifically on fiber-dense fruits, that it promotes control over appetite, creating a feeling of fullness. This has been found to be because of the fact fiber slows the rate at which the stomach empties after a meal, so as to increase the rate of digestion. As a result, eating a high fiber fruit like grapefruit will help individuals eat fewer calories by way of satiating their appetite faster. Another obvious benefit that can eventually come from this is weight loss.

Prevents Insulin Resistance

Studies on grapefruits effects on insulin for individuals with diabetes and obese individuals have found it to help prevent insulin resistance. This is thanks to the low glycemic index of the grapefruit, at around twenty-five. This means it does not raise blood sugar as quickly or as much as foods with a high glycemic index, like a white bagel (at seventy-two), a banana (at forty-eight), or a watermelon (at seventy-two). The highest glycemic index food can have is one hundred. A study published in the Journal of Medicinal Food in 2006, determined individuals who consumed grapefruit juice or half of a grapefruit before a meal had lower insulin spikes two hours later as compared to the placebo group. Fresh grapefruit caused less insulin resistance.
