Fiber in foods like grapefruit helps you feel full and improves digestion, but such foods don't hold any powers to help cleanse your body. A diet cleanse using any food, even grapefruit, is more hype than fact. If you're trying to improve your health, eating a healthy and balanced diet that includes healthy fruits such as grapefruit is a good place to start.
Fiber in Grapefruit
Half a grapefruit has 52 calories and 2 grams of fiber, meeting 8 percent of the daily value. Most of the fiber in the grapefruit is soluble fiber, best known for helping lower cholesterol. But this type of fiber also lengthens digestion time, which may aid in hunger control, and helps slow the absorption of sugar.
Grapefruit Fiber Cleanse
There is no specific grapefruit fiber cleanse, but a cleanse generally means limiting your intake to one food item for a set period of time. While most fruit cleanse diets involve juice, to get the fiber from the grapefruit, you would need to eat the entire fruit in whole or blended form. These types of diets are generally promoted as a way to rid your body of toxic substances and improve health. According to a 2008 article in Today's Dietitian, however, there's no scientific evidence to support these claims.
Grapefruit and a Healthy Diet
That doesn't mean grapefruit can't make a healthy addition to your diet. Not only are grapefruits low in calories and full of fiber, but they're also rich in vitamin C, meeting more than 60 percent of the daily value in one half. The pink and red varieties are rich in vitamin A, too.
Including grapefruit as part of an overall healthy diet is the best way to keep your body free of toxic substances. Healthy foods, such as those rich in fiber and low in fat, keep your liver and kidneys in tip-top shape. These two organs are responsible for cleansing your body of harmful substances.
Warnings About Grapefruit
Unfortunately, not everyone can enjoy eating grapefruit. If you're taking any medication, consult your doctor or pharmacist about whether they interact with grapefruit. A substance in grapefruit blocks an enzyme in your digestive system that metabolizes a variety of prescription medications, allowing more of the medication to enter your bloodstream, which can be dangerous. Medications most often affected include cholesterol- and blood pressure-lowering drugs, organ transplant medications and anti-anxiety pills.
