Crystallized ginger, also known as candied ginger, is a popular sweet and spicy confection often consumed for its purported health benefits. This product is created by cooking pieces of ginger root in a sugar syrup until the root softens, followed by drying and a final coating in granulated sugar. The result is a chewy, intensely flavored nugget that stands at the intersection of a traditional herbal remedy and a processed sweet. Determining whether crystallized ginger is beneficial requires balancing the therapeutic properties of the ginger root with the significant alterations introduced by the preservation method.
The Health Properties Derived from Ginger Root
The medicinal reputation of ginger root stems from its high concentration of bioactive compounds, primarily gingerols and shogaols. In fresh ginger, gingerols, particularly 6-gingerol, are the most abundant pungent compounds. These compounds exhibit notable anti-inflammatory and antioxidant properties, contributing to ginger’s use in traditional medicine for reducing pain and discomfort.
Gingerols are also recognized for their direct effects on the digestive system. They alleviate nausea and vomiting associated with motion sickness and pregnancy by interacting with receptors in the gut and nervous system. This helps regulate the body’s digestive processes, making the raw root a useful aid for various stomach discomforts.
During the heating and drying processes used to create crystallized ginger, gingerols undergo a chemical transformation. Heat causes a dehydration reaction, converting gingerols into shogaols. Shogaols are considered more pungent and may offer enhanced biological activities compared to their precursors. This chemical shift means that processed ginger products contain a slightly different, yet still active, profile of beneficial compounds.
The Impact of the Crystallization Process
The process of turning raw ginger into its crystallized form introduces a significant nutritional drawback due to the massive addition of sugar. Crystallization is a preservation method where the ginger is saturated with a heavy sugar syrup, dried, and coated with more sugar. A typical small serving can contain over 20 grams of total sugar, representing a substantial portion of the daily recommended limit.
This high concentration of added sugar significantly increases the caloric density of the product, with nearly all calories coming from carbohydrates. For individuals monitoring sugar intake or managing conditions like diabetes, the high glycemic load presents a clear concern, as consuming this confection can lead to rapid spikes in blood sugar levels.
The heavy sugar content transforms the product from a low-calorie root into a dense, sugar-laden candy. While sugar helps preserve the ginger and makes it more palatable, it fundamentally changes its nutritional profile. This impact is the primary reason for caution when considering crystallized ginger as a routine health supplement or snack.
Comparing Crystallized Ginger to Fresh Ginger
The most significant difference between crystallized ginger and fresh ginger is the content of water, fiber, and sugar. Fresh ginger root is composed of nearly 80% water and contains dietary fiber, protein, and minerals. Crystallized ginger, having been cooked and dried, loses most of its water and gains a large volume of sugar, resulting in a product that is mostly concentrated carbohydrates.
The cooking process alters the ratio of gingerols to shogaols, increasing the concentration of shogaols and potentially altering the overall pungency and specific biological activity. However, crystallized ginger still retains a large percentage of the bioactive compounds, estimated at approximately 75% of the gingerols found in the fresh root. This retention means the crystallized form remains effective for digestive support and nausea relief.
The trade-off for its convenience and sweetness is the nutritional density. While fresh ginger can be consumed freely in cooking or tea, crystallized ginger must be approached with moderation due to the added sugars. A small, controlled portion can be an effective and convenient remedy for sudden nausea, where the sugar may even provide quick energy. For general anti-inflammatory benefits or daily consumption, however, a low-sugar form like fresh or dried ginger is a more prudent choice.
