Superfood Spotlight: Ginger

The Superfood of All Superfoods

Ginger (Zingiber officinale) is a popular herb used globally, both in the culinary world and in herbal medicine. The ginger plant is thought to have originated in southeastern Asia, and its spiritual and medicinal uses date back about 5,000 years in Southeast Asia, China, and India.1 In the first century CE, ginger made its way into the Mediterranean region, brought by traders, and by the 11th century, ginger was being traded in England, the West Indies, Chile, and Spain.2 Ginger was highly valued as a flavoring agent and for its medicinal and spiritual uses, and some sources state that in the 14th century CE, a pound of ginger was equivalent in price to that of one sheep.1 By 1550 CE, Europe was importing 2,000 tons of ginger a year from the East Indies.1 

The ginger plant, which can grow up to three feet in height, has green reedy stems wrapped in sheaths, from which long narrow leaves emerge. It somewhat resembles bamboo. Ginger flowers emerge from dense cone-like spikes. Ginger thrives best in warm, humid environments.2 

The spicy aromatic herb/spice we know and love as ginger is often referred to as ginger root, but this is a misnomer because it is the rhizomes of the plant, not the roots, that are harvested. Interesting to note: ginger is propagated by planting root stalk cuttings, and this method of cultivation has been used for so long that ginger no longer produces seeds.2 When harvested, the rhizomes are lifted from the ground, cleaned, and dried, resulting in the brownish tan, knobby, fist-sized lumps we see at the grocery store.2 


One tablespoon of fresh ginger has 4.8 calories, 1.07 grams of carbohydrates, 0.12g of dietary fiber, 0.11g of protein, 0.5g of fat, and 0.1g of sugar.3 Ginger contains trace amounts of vitamins B3 and B6, iron, potassium, vitamin C, magnesium, phosphorus, zinc, folate, riboflavin, and niacin.3 


Ginger is the epitome of a superfood. Over 400 bioactive components have been found in ginger, including phenolic (gingerols, shogaols, paradols, quercetin, zingerone, gingerenone-A, and 6-dehydrogingerdione) and terpene (β-bisabolene, α-curcumene, zingiberene, α-farnesene, and β-sesquiphellandrene) compounds. Additionally, ginger contains polysaccharides, lipids, organic acids, and raw fiber.4–19 Numerous studies have demonstrated multiple biological activities in ginger, including antioxidant, anti-inflammatory, antimicrobial, anticancer, neuroprotective, cardiovascular protective, respiratory protective, antiobesity, antidiabetic, antinausea, and antiemetic properties.4–19 In short, ginger has been well-studied, and its medicinal effects are well supported by numerous high-quality scientific reports.

Gingerols are the primary bioactive components in ginger, and their strong antioxidant and anti-inflammatory properties are responsible for much of ginger’s other medicinal properties.4–19 


Fresh ginger can be chopped, sliced, diced, or grated and eaten raw or cooked; it can be pickled or preserved; and it can be dried and ground into powder form (or if that is outside the scope of your daily to-dos, you could just buy it in the spice aisle). You can also get it in supplement form, as an essential oil, and as a tincture, but consult with a physician before using ginger in these forms.


The medicinal properties of ginger have been demonstrated in numerous animal and human studies; however, additional larger, randomized, controlled human studies are needed to better support these results..

Editor’s note. Consult with a qualified healthcare professional to determine if ginger supplementation is right for you.
