The Journal of Medicinal Food carried a study article that stated that having half a grapefruit before meals helped the consumers in controlling post prandial blood sugar and improving insulin resistance compared to those on grapefruit juice or placebo.

Increases production of collagen

Its high vitamin C content increases formation of collagen. Collagen production decreases with age. Hence adding this to diet is beneficial. Gabriela explains:

“Collagen makes up about 30% of bone structure, a large amount of tendon and ligament tissue, and is important for skin and blood vessel structure,”

Heart healthy

Dietitian Breanna Woods from Blogilates says:

“Grapefruit supports heart health thanks to its high fiber, potassium, and antioxidant content,”

Increases iron absorption

The high vitamin C content increases iron absorption. Gabriela says:

Iron is important for moving oxygen through the bloodstream via red blood cells to bring oxygen to cells,”


Grapefruit is nutrients dense. And has low calories. But it has been part of controversial fad diets such as the Grapefruit diet or the Hollywood diet. This diet promises weight loss. But it is not sustainable. The diet is not healthy in the long term.

This diet that was popular in the 1930s still has many supporters of it. It claims that grapefruit burns fat faster. But there is no scientific backing for this claim. Grapefruit does not have any magical fat burning capacity.

Grapefruit can also interact with some medicines. Nicole Lindel, outpatient gastrointestinal dietitian at Everly Health says:

“Grapefruit interacts with many drugs, which can cause too much or too little of the drug in our body,”

“For example, grapefruit can block the action of enzymes needed to break down certain cholesterol-lowering medications such as Lipitor.”
