The many benefits of grapefruit
Grapefruits are bursting with vitamin C, and also provide vitamin A (as beta-carotene in pink and red varieties), potassium, fibre and the antioxidant lycopene.
An important medication warning Grapefruit and grapefruit juice interact with a number of common prescription medications, including some statins, blood pressure and heart medications, by blocking an enzyme (CYP3A4) your body uses to break them down. This can let the medication build up to unsafe levels. If you take any prescription medication, check with your doctor or pharmacist before adding grapefruit to your routine.
Wellness
This sweet and tangy citrus fruit (Citrus × paradisi) is loved for its refreshing flavour. Here is what it brings to a balanced diet:
Immune health Half a grapefruit provides around half of an adult’s daily vitamin C needs, which supports the normal function of your immune system.
Antioxidants Pink and red grapefruit contain lycopene and beta-carotene, antioxidants that help protect your cells from oxidative stress. Some studies suggest men who eat more lycopene-rich foods may have a lower risk of prostate cancer, though research is still ongoing.
Heart health Grapefruit’s soluble fibre (pectin) can help lower LDL cholesterol, and its potassium supports healthy blood pressure.
Digestive health The fibre in grapefruit supports regular, healthy digestion. Despite a popular myth, there is no good evidence that grapefruit dissolves gallstones.
Hydration Grapefruit is around 90% water, making it a refreshing way to stay hydrated.
Beauty
Collagen support Vitamin C is needed to make collagen, which keeps skin firm and elastic, and grapefruit’s antioxidants help protect skin from free radical damage.
Weight management
Fibre and water Half a grapefruit has only around 220 kJ (52 calories) and about 2 grams of fibre. Its high water and fibre content help you feel full, so it is a smart start to a meal.
The “fat burner” myth Grapefruit doesn’t contain fat-burning enzymes. It can be a helpful part of a weight management plan simply because it is filling and low in kilojoules.
Cooking with grapefruit
Grapefruits can be eaten raw, grilled, baked and juiced. In Australia they are at their best through winter and early spring.
Slice them into your favourite healthy salad for a punch of tart sweetness. Combine grapefruit with orange and chia seeds and make a lip-smacking Sunday marmalade.
Grapefruit has a natural affinity with seafood and is a perfect addition to a scallop ceviche. Grab a few grapefruit wedges and give them a quick pan sear to accompany a dozen plump prawns as a fresh and fit entrée. You can also whisk together ruby red grapefruit juice and tarragon (or another favourite herb such as bergamot) into a vinaigrette to spoon over grilled blue eye cod or sea bass, or concoct a sweet and sour grapefruit jelly to serve with a herbed roast pork loin.
Grapefruit slices can be candied and enjoyed throughout the year as a unique snack, and grapefruit zest can be incorporated into an array of luscious vegan dishes for a zesty twist.
Interesting fact: This fruit got its name because it grows in clusters on trees, much like grapes do.
