Nutritional Benefits Of Ginger

Ginger is mentioned in ancient writings from China, India, and the Middle East. It has long been praised for its aromatic and culinary qual­ities. However, ginger is probably best known for having a myriad of different medicinal properties. Of these, the first and foremost is ginger’s ability to bring relief from gastrointestinal problems such as nausea. Ginger is also thought to be useful for anti-inflammatory illnesses such as osteoarthritis. The spicy taste of ginger is believed by people that it may promote cardiovascular health. Of course, it is important to review the research to find the facts.

Three Studies On The Nutritional Benefits Of Ginger In Controlling Nausea

An Australian study published in 2003 in the Australian and New Zealand Journal of Obstetrics and Gynecology examined the effect ginger extract had on the morning sickness of 120 women, all of whom were less than 20 weeks pregnant. The study included two types of women. First, those who had daily bouts with morning sickness for at least one week. Second, women for whom no relief was obtained from dietary modifications.

The women received either 125 mg of ginger extract or a placebo four times per day. After the first day, the women consuming ginger extract had significantly less nausea than the women taking the placebo. While there were no significant differences in vomiting, the women on ginger experienced less retching. The researchers concluded that “Ginger can be considered a useful treatment for women suf­fering from morning sickness.”

A second study on the use of ginger for morning sickness in Australian women was published in 2004 in Obstetrics & Gynecology. For three weeks, 291 women, who were less than 16 weeks pregnant, were given either 1.05 g of ginger or 75 mg of vitamin B6 every day. In both groups, more than half of the women improved; there were no significant differences in outcomes. The researchers concluded, that, for “women looking for relief from their nausea, dry retching, and vomiting, the use of ginger in early pregnancy will reduce their symptoms to an equivalent extent as vitamin B6.”

Ginger And Surgical Recovery

In a study conducted in Thailand and published in 2007 in Alternative Medicine Review, researchers attempted to determine if a bulk amount of ginger could reduce or prevent nausea and vomiting that often follows major gynecologic surgery. Researchers studied a total of 120 women undergoing major gyne­cologic surgery. Before surgery, 60 women received two capsules of ginger; another 60 women received a placebo. The researchers indicated that the women who had pre-surgery ginger had statistically significantly less nausea and vomiting. The researchers noted that “ginger has efficacy in prevention of nausea and vomiting after major gynecologic surgery.

Another study from Thailand, published in 2006 in the American Journal of Obstetrics & Gynecology, reviewed five randomized, double-blinded, pla­cebo-controlled trials including a total of 363 patients. All of the studies compared the use of a fixed dose of ginger to placebo on 24-hour-post­ operative nausea and vomiting in patients having gynecological or lower extremity surgery. The incidence of postoperative nausea and vomiting in those who received ginger was clearly lower. At least one gram of ginger was more than a third less than those who received placebos. Still, the study has some limitations. For example, the majority of the patients were Asian with an average weight of only 50 kg. Dosage requirements may need to be increased for people who are larger. Nevertheless, the researchers concluded that the “use of ginger is an effective means for reducing postoperative nausea and vomiting”.


It is also well known that people receiving chemotherapy treatments fre­quently experience nausea. A study published in 2006 in Neurogastroenterol­ogy & Motility attempted to determine if high-protein meals combined with ginger could help control post-chemotherapy nausea. For three days after chemotherapy treatments, 28 cancer patients were placed in one of three groups. The control group ate their normal diets. The second group ate a protein drink and one gram of ginger root twice each day. A third group ate a protein drink and additional protein powder and one gram of ginger root twice a day. The researchers found that the “high protein meals with ginger reduced the delayed nausea of chemotherapy, and reduced the use of antiemetic [anti-nausea] medications. Anti-nausea effects of high protein meals with ginger were associated with enhancement of normal gastric myoelectrical [electricity generated by muscle] activity and decreased gastric dysrhythmias [abnormal stomach electrical activity].”

Diabetic And Cardiovascular Health

Cardiovascular Health

Researchers at Kuwait University studied the role that ginger may play in rats who have been treated to develop diabetes. In a study published in 2006 in the British Journal of Nutrition, researchers noted that rats that developed diabetes tended to have high blood sugar and weight loss. The researchers fed these rats raw ginger- 500 mg per kg of body weight per day- for seven weeks.

TA separate group of rats, which did not receive any ginger, served as the con­trol group. The study showed the rats that were fed ginger had consider­ably lower levels of blood sugar, cholesterol, and triglycerides. The nutritional benefits of ginger included alleviating the diabetes effects including protein in the urine, excessive urine output, and excess water intake. “Therefore, it can be concluded from these studies that raw ginger has significant potential in the treatment of diabetes.”

Osteoarthritis Of The Knee

Osteoarthritis Of The Knee

In a study published in 2001 in Arthritis & Rheumatism, subjects with mod­erate to severe pain from osteoarthritis in their knees were divided into two groups. One group took 255 mg of concentrated ginger root twice daily for six weeks, while the other group had placebos. Following a washout period, the group who originally had ginger was given placebos and the group who originally had placebos was given ginger. In the end, 247 patients were evaluated…The researchers found that ginger markedly improved the pain from osteoarthritis. “A highly purified and standardized ginger extract had a statistically significant effect on reducing symptoms of OA [osteoar­thritis] of the knee.” But, some of the participants reported gastrointestinal side effects such as belching, gas, nausea, and mild heartburn.

In an article published in 2005 in the Journal of Medicinal Food, research­ers from the Department of Orthopedic Surgery at Johns Hopkins Univer­sity School of Medicine noted that the anti-inflammatory properties of ginger have been known for centuries. It is now generally recognized that “ginger modulates biochemical pathways activated in chronic inflammation”. But, an article published in 2007 in American Family Physician appears to disagree. The author commented on the nutritional benefits of ginger being used to alleviate arthritis. Brett White, MD, wrote, “Mixed results have been found in our studies of ginger for the treatment of arthritis symptoms.”

Should ginger be part of the diet? For the vast majority of people, yes.
