💡 Smart Nutritional Guidance
Consumption advice
Half a large grapefruit in the morning, eaten with a spoon, gives great hydration and fullness, and its light natural bitterness helps curb an excessive appetite all day.
Best preparation methods
Cut the fruit in half and spoon out the segments with their thin inner membranes to get all the fibre, and avoid juicing it, which strains out the beneficial fibre.
Important Nutritional Note
⚠️ Critical clinical and drug warning: grapefruit contains furanocoumarins that inhibit the liver enzyme CYP3A4, which can cause dangerous build-up of certain medicines in the blood (such as statins for cholesterol, some blood-pressure drugs and immunosuppressants). Anyone taking these medicines should consult their doctor and avoid grapefruit.
