What is Ginger?

Ginger, also known as Zingiber officinale, is a flowering plant, whose root or rhizome is used as a spice. It can be consumed in many forms, fresh, dried, powdered, and in the form of oil and juice. Ginger is a common ingredient in Asian cuisines where it is used to build flavors in curries, dressings, and soups. It is also used in sweets and alcoholic beverages such as ginger cookies, ginger beer, and wine. ^[1]

Today, ginger is on the FDA’s list of generally safe foods and is often used to mask the taste of bitter medicines such as cough syrups.

Ginger Nutrition

Most of the benefits derived from ginger are because of the presence of an active constituent called gingerol. According to the USDA FoodData Central, it is also rich in carbohydrates, dietary fiber, and protein. In terms of minerals, it has sodium, iron, potassium, magnesium, phosphorus, and zinc. its vitamins include vitamin C, folate, vitamin B6, riboflavin, and niacin. ^{[3] [4]}

There are many anti-inflammatory and antioxidant compounds like pantothenic acid, beta-carotene, capsaicin, curcumin, caffeic acid, and salicylate in it. Also, the presence of active compounds like shogaol, zerumbone, terpenoids, flavonoids, paradol, and zingerone in ginger provides many health benefits. ^[5]

Health Benefits of Ginger

While the traditional uses of ginger for better health are numerous, today we can easily add to it the multiple beneficial properties discovered and confirmed by research. Let’s take a look at some of the most popular health benefits of ginger.

May Relieve Nausea

The consumption of fresh ginger has been shown to be effective in alleviating various forms of nausea, including morning sickness, motion sickness, and chemotherapy side effects. This may be due to its ability to increase gastric motility and block serotonin receptors in the gut lining, which can help to silence the nerves that trigger the vomiting reflex. ^[6]

Although a study published in Nutrition Journal reveals that ginger may help in relieving nausea during pregnancy, but was not seen to be as effective in treating problems of vomiting. Significantly, it did not show any side effects, an important factor when treating pregnant women.
Ginger is not recommended for use during pregnancy, especially for people close to labor, with a history of pregnancy loss or vaginal bleeding, or with clotting disorders. ^[7]

Its quick absorption and rapid regulation of body functions cure nausea in people who have undergone surgeries, without any side effects.

May Aid in Weight Loss

Ginger can potentially aid in weight loss through various mechanisms. It’s known to boost metabolism, suppress appetite, regulate blood sugar, and reduce inflammation, all of which are relevant factors in weight management.

• Reduce inflammation: Inflammation is a major contributor to obesity and weight gain. Ginger compounds such as 6-shogaol, zingerone, and 8-shogaol have been shown to decrease inflammation and improve symptoms in both human and animal models. ^[10]
• Boost metabolism: Ginger has been shown to boost metabolism in animals. A recent study found that ginger supplementation increased energy expenditure and fat burning in rats. ^{[11] [12]}
• Reduce appetite: A study found that ginger supplementation reduced hunger and increased fullness in people with overweight or obesity. ^[13]

It is important to note that the research on the effects of ginger on weight loss is still in its early stages. More research is needed to confirm the long-term safety and efficacy of ginger supplementation for weight loss.

May Treat Cold and Flu

This is traditionally used in many Asian countries against cold and flu. A study published in the Journal of Ethnopharmacology found that fresh ginger shows potential antiviral properties against respiratory tract infections. It can be used in the form of tea for providing relief to sore throat and coughing. ^{[14] [15]}

May Aid in Digestion

Ginger finds a prominent mention in Chinese medicine as a facilitator of the digestive process. While many of its benefits are established part of traditional medicinal history, a review published in 2019 in the journal Food, Science & Nutrition asked for more human studies to understand effective dosage. The study, however, agreed that there was substantial anecdotal evidence, backed by clinical trials. ^[16]

It is also frequently used as an appetizer or an aperitif since it can stimulate the appetite while preparing the digestive system for an influx of food. It works well as a carminative, thus helping with flatulence. ^[17]

May Be Remedial for Stomach Ulcers

Ginger may prevent the occurrence of ulcers, which are generally characterized by bleeding and acute gastric irritability. It has anti-inflammatory and antibacterial properties that can help to reduce inflammation and kill the bacteria that cause ulcers. ^{[18] [19]}

May Relieve Asthma

Ginger has been used traditionally as a potential medicine to treat respiratory disorders. A study conducted in 2015  also seconded its potential anti-inflammatory properties. Zerumbone, an active compound, may help relieve asthma. Research shows that allergic airway inflammation is majorly caused by Th2 dominance and the spicy root is successfully able to suppress it. ^{[25] [26]}

Recent animal studies have shown ginger’s active components, gingerol, and shogaol may have the potential as a therapeutic option for asthma. More research is needed to confirm the safety and efficacy of ginger for the treatment of asthma in humans. ^{[27] [28]}

May Aid in Liver Protection

People suffering from tuberculosis can benefit from ginger, as it helps prevent hepatotoxicity. Animal studies show that it also protects against the liver-damaging cadmium poisoning caused due to the significant ingestion of cadmium. Its essential oil exerts a protective effect against the non-alcoholic fatty liver disease occurring because of obesity. ^{[29] [30] [31]}

May Relieve Muscle Pain

Ginger is well-known for reducing muscle pain and soreness caused due to exercising. The potentially anti-inflammatory properties of this root are to be credited for this benefit. The study points out that ‘daily consumption of raw and heat-treated ginger resulted in moderate-to-large reductions in muscle pain following exercise-induced muscle injury.’ ^{[32] [33] [34]}

May Help Manage Dysmenorrhea

Ginger may help reduce the levels of prostaglandins in the body, hence it aids in relieving cramps and other forms of discomfort and pain during menstruation. Scientists believe that high levels of prostaglandins contribute to increased menstrual cramps. These hormones function as chemical messengers are the key activators of symptoms such as cramps, pains, and fevers.

Might Boost Heart Health

Ginger may protect cardiovascular health by lowering LDL cholesterol levels and increasing HDL cholesterol levels. ^{[38] [39]}

A meta-analysis of 26 randomized controlled trials showed that ginger consumption could significantly improve total triglyceride, cholesterol, LDL, and HDL levels. The most effective dose was >1500 mg/d for more than 8 weeks. It may also reduce the risk of blood clotting, thereby helping regulate hypertension and keeping your heart healthy. ^{[40] [41]}

May Control Diabetes

Ginger may help regulate the blood sugar levels in people suffering from type 2 diabetes. Glycemic and lipid abnormalities lead to long-term complications in diabetics, as per a research study published in the International Journal of Endocrinology Metabolism in 2017. Therefore, to improve your insulin resistance and control diabetes, consider adding this root to your diet. Another study published in the journal Complementary Therapies in Medicine in 2014 demonstrated “daily consumption of 3 one-gram capsules of ginger powder for 8 weeks is useful for patients with type 2 diabetes.” ^{[42] [43]}
