Pink grapefruit and white grapefruit, also called yellow grapefruit, are closely related varieties of the same citrus fruit, Citrus paradisi. It is a hybrid that emerged from the cross of a variety of grapefruit and a variety of sweet orange that was originally developed in Barbados. Most of the grapefruits sold in the United States come from Florida, although Texas and California are also big producers. The grapefruit tree produces a large fruit with a bitter and slightly bitter taste.
The biggest difference between white and pink grapefruits is the vitamin A content. Pink grapefruit has significantly higher levels of this nutrient. One cup of pink grapefruit provides approximately 2. 645 international units or 50 percent of the recommended daily intake of vitamin A. In contrast, white grapefruit only offers 2 percent of the recommended daily allowance.
Vitamin C and potassium
Although white and pink grapefruits differ considerably according to the amounts of some nutrients, in other cases they are essentially equivalent. All varieties of grapefruit have high levels of vitamin C and there is a slight difference between pink and white grapefruit in relation to this nutrient. One cup of grapefruit provides approximately 70 mg or 120 percent of the vitamin C needed per day. The white and pink grapefruits also have almost the same amount of potassium. One cup contains approximately 300 mg or 15 percent of the recommended daily intake.
Sugar, fiber and calories
The sugar, fiber and calories of pink and white grapefruits are comparable in general terms. One cup of pink grapefruit contains approximately 97 calories, 16 g of sugar and 4 g or 15 percent of the recommended daily fiber intake. One cup of white grapefruit has 76 calories, 17 g of sugar and 3 g or 10 percent of the recommended daily fiber intake.
The pink grapefruit is notably sweeter than the white grapefruit, even though the sugar content is comparable. As a result, pink grapefruit is preferred by many consumers and is now sold more and can be found more easily than white grapefruit varieties.
Grapefruit and medication
Some enzyme found in grapefruit juice may interact with certain prescription drugs and increase their effects considerably and, occasionally, dangerously. The drugs used to treat hypertension and thyroid conditions are among the drugs affected. Consult your doctors before consuming grapefruit juice regularly if you take any prescribed medication.
