21 Powerful Reasons to Eat Grapefruit

From supporting your immune system to improving your cholesterol levels, there are many powerful reasons to eat grapefruit. Grapefruit contains a juiciness that competes with that of the popular orange and shines with many of the same health benefits. Grapefruits are about 75 percent juice. The average grapefruit produces almost two-thirds of a cup of fresh-squeezed juice, which retains 98 percent of its vitamin C in the refrigerator for up to a week. Texas, Florida and California are known worldwide for their groves, but grapefruit originally came from Barbados where they were dubbed “the forbidden fruit”. Varieties of grapefruit include Ruby Red, Star Ruby, and Pink, among others. Although grapefruit is available all through the year, they are in season and at their very best in taste and juiciness from winter through early spring.

A 2006 study that compared men who consumed lycopene-rich foods the most with those who consumed the least, the men who consumed the most were found to be 82 percent less likely to develop prostate cancer.

Another study indicates that eating grapefruit can lower the risk of developing kidney stones. Limonin, another phytonutrient, suppresses cancerous cell and tumor growth. The pectin in grapefruits stops hardening of the arteries and lowers the LDL or “bad” cholesterol, in fact reducing it dramatically in a matter of days in even low amounts. And the flavonoid naringinen, inhibits hepatitis C virus, repairs DNA in prostate cancer cells and may prevent dyslipidemia (high blood cholesterol) and diabetes.

Be aware that consuming grapefruit may, in rare cases, interfere with certain prescription and over-the-counter medications. Be sure to talk to your healthcare professional as to whether or not grapefruit consumption could interfere with your medications.

More Research: Reasons to Eat Grapefruit

A study on the effects of grapefruit on insulin resistance, body weight, and metabolic syndrome involved 91 obese patients in groups consuming placebos, apple juice, grapefruit juice, grapefruit capsules, or fresh grapefruit. Over twelve weeks the fresh grapefruit group lost much more weight than the placebo group. Half of a fresh grapefruit eaten before meals also was associated with significant weight loss, improved insulin resistance, and a reduction in two-hour post-glucose insulin level. Researchers concluded that, while the mechanism of the weight loss was unknown, eating grapefruit as part of a weight loss program was effective in losing some weight.

Grapefruit, limonin, grapefruit pulp powder and the flavonoid naringen (similar to naringinen) were examined in another study for their abilities to subdue the proliferation of and programmed death of colon cancer cells. Results indicated that only untreated grapefruit and limonin suppressed carcinogens or raised the cancer cell-neutralizing index. Scientists concluded from these findings that eating grapefruit may help inhibit colon cancer development.
