Naringin

What Is It?

A flavonoid compound found in grapefruit, naringin gives grapefruit its characteristic bitter flavor. Grapefruit processors attempt to select fruits with a low naringin content, and often blend juices obtained from different grapefruit varieties to obtain the desired degree of bitterness. Naringin is believed to enhance our perception of taste by stimulating the taste buds (some people consume a small amount of grapefruit juice before a meal for this reason).

Health Benefits

Naringin may be instrumental in inhibiting cancer-causing compounds and thus may have potential chemotherapeutic value.

Studies have also shown that naringin interferes with enzymatic activity in the intestines and, thus, with the breakdown of certain drugs, resulting in higher blood levels of the drug. A number of drugs that are known to be affected by the naringin in grapefruit include calcium channel blockers, estrogen, sedatives, medications for high blood pressure, allergies, AIDS, and cholesterol-lowering drugs. Caffeine levels and effects of caffeine may also be extended by consuming grapefruit or grapefruit juice.

While the effect of naringin on the metabolism of a drug can increase the drug’s effectiveness, it can also result in dosages that are inadvertently too high. Therefore, it’s best not to take any drugs with grapefruit juice unless the interaction with the drug is known. In addition, the effects of drinking grapefruit juice is cumulative, which means that if you drank a glass of grapefruit juice daily with your medication for a week, the drug interaction would be stronger at the end of the week than at the beginning.

  • Covid-19 Worries

    You may have noticed fewer Health Tips about Covid-19 recently, which might have struck you as odd given our dreadful numbers here in the US. Well, there was a reason for this. WholeHealth Chicago was one of hundreds of health-oriented websites that were sent cease-and-desist warning letters from the Federal Trade Commission (FTC) alleging widespread promotion and selling what they called “unproven therapies.” In other Read More

  • You Probably Don’t Need A Colonoscopy

    Quite often the patient sitting before me helpfully finishes my sentence. “Yeah, yeah, I know, I need a colonoscopy.” This happens in person or during a Telemed visit when I remark how they’re approaching (or recently turned) 50, 60, or beyond. Or they’re a few years beyond 50 or 60, and I genially ask, “Your colonoscopy current?” I do not willfully induce the stricken look Read More

  • Returning To School + Phosphatidyl Choline for Chronic Illness and Anti-Aging

    Before I start this Health Tip on phosphatidyl choline I want to voice a quick opinion about kids returning to school in the Chicago Public School (CPS) system. The stance of the Chicago Teachers Union seems totally correct, that the decision should be based on a meeting of the minds: those of teachers and those of scientists (who, you’ll remember, were once taught by teachers).
