While delicious consumed on its own, grapefruit juice also makes the perfect complement to other foods by adding a unique, exciting flavor and burst of nutrients to everyday dishes. Aside from its tangy, invigorating taste, this naturally nutrient-rich beverage also delivers a variety of valuable health and nutrition benefits, making it a smart choice for daily consumption.

 

100 percent grapefruit juice is a naturally nutrient-rich beverage that offers many health benefits, such as:

Antioxidants One 8-ounce glass of grapefruit juice provides 100 percent or more of the Daily Value for vitamin C. Vitamin C is an important antioxidant. Antioxidants may help neutralize free radicals formed as part of the body’s natural oxidation processes. Many scientists believe the long term presence of excessive free radicals may damage cells and tissues and contribute to the development of certain chronic diseases.

Weight Management One 8-ounce serving of grapefruit juice is fat-free and, at less than 100 calories per 8-ounce glass, has fewer calories than some other commonly consumed 100 percent fruit juices.1 One hundred percent grapefruit juice is a healthful and nutrient-rich replacement in the diet for foods and beverages containing added sugars.

Heart Health Research suggests that the consumption of grapefruit and grapefruit juice is associated with a positive impact on heart health indicators such as HDL cholesterol2 and total cholesterol.3 One hundred percent grapefruit juice is also sodium-free, saturated fat-free, and cholesterol-free and can be a part of a heart-healthy diet and lifestyle.

Immune System Support An 8-ounce glass of grapefruit juice provides vitamin C, plus other nutrients and phytochemicals that may help support a healthy immune system.

Fruit Intake One hundred percent grapefruit juice counts as a fruit choice to help meet fruit intake recommendations.4 Americans, especially children and adolescents, fall well short of meeting fruit intake recommendations.5-7 Remember to make half your plate fruits and vegetables.8

Skin Health Vitamin C found in grapefruit juice can help support collagen production, which may support healthy skin and gums. Collagen breakdown in the skin may lead to the appearance of premature aging.

Vitamin Absorption Citrus foods like grapefruit juice are high in vitamin C, which may help aid the absorption of non-heme iron (the iron found in plants like spinach, not meat products). Vitamin C-rich foods should be consumed daily to help get the most iron from foods.4

What makes grapefruit juice so great for you?

Vitamin C

An 8-ounce glass of 100 percent grapefruit juice is an excellent source of vitamin C.

An 8 ounce glass of grapefruit juice provides 100 percent or more of the Daily Value for vitamin C. Citrus juices are reported to be the largest contributor of vitamin C in the diet.9

Vitamin C is a nutrient known to be important to the immune system and intake of vitamin C-rich foods may help support a healthy immune system.

Vitamin C can help support collagen production which is important for maintenance of healthy skin, bones, cartilage, muscle and blood vessels.

Vitamin A & Carotenoids

An 8-ounce glass of 100 percent pink or red grapefruit juice is an excellent source of vitamin A.

Carotenoids are pigments found naturally in some foods, primarily fruits and vegetables.

Pink and red grapefruit juice contains beta-carotene, a carotenoid that helps give grapefruit its color and serves as a source of vitamin A in the diet.

In the body, vitamin A can help support reproduction and growth, immune function, and healthy vision.

Potassium

An 8-ounce glass of 100 percent grapefruit juice is a good source of potassium.

Grapefruit juice provides potassium, which is a mineral important for muscle function, nerve transmission, pH maintenance (acid/base balance), and maintaining fluid and electrolyte balance.

Potassium has been identified as a Nutrient of Concern in the Dietary Guidelines for Americans,4 meaning that many Americans do not get enough of this important mineral.

Potassium may play an important role in our cardiovascular health. Diets containing foods that are a good source of potassium and low in sodium may reduce the risk of high blood pressure and stroke.10

Folate

An 8-ounce glass of 100 percent grapefruit juice supplies 6% of the Daily Value for folate.

Folate is important for cell division and the production of healthy red blood cells.

Folate is essential for growth and development and may help reduce the risk of birth defects of the brain and spinal cord, known as neural tube defects.

To help reduce the risk of someday having a baby with a neural tube defect, women capable of becoming pregnant should get 400 micrograms of the synthetic form of folate (folic acid) every day while consuming food folate (the form found in foods and beverages such as orange and grapefruit juice) from a varied diet.14

Have a glass of 100 percent orange juice to increase folate in your diet.

Folate may significantly modify homocysteine (an amino acid) levels in the body. High levels of homocysteine in the blood have been associated with an increased risk of coronary heart disease.14

Phytonutrients

Phytochemicals are any chemicals that come from a plant. Phytonutrients are the subgroup of those plant components that may have nutrient characteristics when consumed by animals. Phytonutrients typically occur in very small amounts and when consumed, may provide people with nutritional or health benefits.

Magnesium

An 8-ounce glass of 100 percent grapefruit juice supplies 6% of the Daily Value for magnesium.

Magnesium helps the body generate energy from the foods we eat and is required for the action of many enzyme systems.

Diets rich in fruits and vegetables that provide key minerals such as potassium, calcium, and magnesium may help contribute to maintaining healthy blood pressure.15

Magnesium may play an important role in bone health, so diets rich in foods with magnesium, such as fruits and vegetables, can optimize the intake of micronutrients required for bone health.16

Thiamin

An 8-ounce glass of 100 percent grapefruit juice supplies 7% of the Daily Value for thiamin.

Thiamin is a water-soluble vitamin associated with the action of many enzyme systems and helps the body process energy from the food we eat.

A healthy diet should include a variety of foods and beverages that provide thiamin.

Calcium

Calcium-fortified grapefruit juice is an excellent non-dairy and lactose free source of calcium.

Calcium aids in bone and tooth development, blood pressure regulation and muscle function.

Calcium has been identified as one of four Nutrients of Concern in the Dietary Guidelines for Americans.4

In the U.S., 10 million individuals are estimated to have osteoporosis already, and almost 34 million more are estimated to have low bone density, placing them at increased risk for osteoporosis and broken bones.17

Flavonoids

Grapefruit contain a variety of phytonutrients, some of which are known as flavonoids, a class of natural compounds.

Naringin is the most common flavonoid found in grapefruit and grapefruit juice is the only fruit juice that contains significant amounts of naringin.

Some flavonoids have been reported to have beneficial effects on the cardiovascular system, skin or bones.12 Flavonoids primarily found in citrus have been associated with improvements in markers of inflammation.13

Vitamin D

Many calcium-fortified grapefruit juices provide over 20% of the Daily Value for vitamin D.

Vitamin D works hand in hand with calcium to help support bone health.

Vitamin D has been identified as one of four Nutrients of Concern in the Dietary Guidelines for Americans.4
