One Grapefruit A Day Helps Lowering Cholesterol, But...

A few days ago, the NYTimes health blog reported a pretty interesting news: the FDA acknowledged that cholesterol-lowering statins carry a risk of cognitive side effects.
If you’re not familiar with this drug, statins help people at high risk of cardiovascular problems, lowering cholesterol, risk of heart attack and stroke. They are one of the most prescribed drugs in the world.
For years doctors have been fielding reports from patients that the drugs leave them feeling “fuzzy,” and have been experiencing big memory problems. Finally the FDA has officially acknowledged that.
This news has raised concern because 21 million patients only in the US were prescribed statins during 2011. It's difficult to assess how many of them have experienced cognitive side effects.
So what’s the solution? Lowering cholesterol through a healthy diet and exercising, easy as that. You can get off statins and no more fear of “losing the mind”.
Among food that help with cholesterol issues one might be particulalry helpful: grapefruit!
A study conducted in Israel demonstrated that eating one ruby red grapefruit a day was as effective as taking statin drugs in the lowering of cholesterol. But beware, you cannot use the two together!



Lowering cholesterol properties

In a study published in the Journal of Agricultural and Food Chemistry, Israeli researchers from the Hebrew University in Jerusalem first tested the antioxidant potential of blond and red grapefruits, and then their cholesterol-lowering potential in humans.
The test tube research showed that red grapefruit contains more bioactive compounds and total polyphenols than blond, but both grapefruits are comparable in their content of fiber, phenolic acid, ascorbic acids, and naringinen (a flavonoid). Although, red grapefruit contains slightly more flavonoids and anthocyanins.
In this recent study, participants added either red grapefruit, blond grapefruit or no grapefruit to their daily diet. The results indicated that both types of grapefruit appeared to lower LDL cholesterol in just 30 days: total cholesterol by 15.5% in those eating red grapefruit and 7.6% in those eating blond grapefruit; LDL cholesterol by 20.3% and 10.7% respectively; and triglycerides by 17.2% and 5.6% respectively. No changes were seen in the group that didn't eat any grapefruit.


Both red and blond grapefruits both positively influenced cholesterol levels, but red grapefruit was more than twice as effective, especially in lowering triglycerides. In addition, both grapefruits significantly improved blood levels of protective antioxidants.
Red grapefruit's better performance may be due to an as yet unknown antioxidant compound or the synergistic effects of its phytonutrients, including lycopene.
In response to this rapid and very positive outcome, the researchers concluded that adding fresh red grapefruit to the diet could be beneficial for persons with high cholesterol, especially those who also have high triglycerides.

But...

Grapefruit effects are pretty strong, in particular, compounds in this fruit are known to increase circulating levels of several prescription drugs, including statins. For this reason, the risk of muscle toxicity associated with statins may increase when grapefruit is consumed.
In other words before embarking on the “One Grapefruit A Day” journey it’s better to check up with your doctor and discuss with him the possibilities of switching from statins to grapefruit.
