Is it OK to eat the skin on ginger?

Ginger is a popular spice used in many cuisines around the world. It adds a distinctive zing and flavor to both sweet and savory dishes. Ginger root is knobby and bumpy, with a tan or brown peel covering the flesh inside. But what should you do with the skin – peel it off or leave it on when eating ginger?

The Benefits of Eating Ginger Skin

The skin of fresh ginger root contains beneficial nutrients and compounds that can provide health advantages. Here are some of the key benefits of consuming ginger with the skin left on:

  • Fiber – Ginger skin is a good source of dietary fiber. A 28 gram serving contains about 2 grams of fiber. Fiber supports digestive health.
  • Gingerol – This phytochemical is responsible for ginger’s pungent aroma and flavor. It also has anti-inflammatory and antioxidant effects. Gingerol is highly concentrated in the skin.
  • Antioxidants – Compounds like gingerols provide antioxidant activity to help neutralize free radicals and prevent cell damage.
  • Vitamins – Ginger skin contains small amounts of vitamins like niacin, riboflavin, and vitamin C.
  • Minerals – Minerals like magnesium, phosphorus, potassium, and zinc are found in ginger skins.

Overall, ginger skin has a unique nutritional profile compared to the inner flesh. Leaving the skin on provides more nutrient density.

Potential Downsides to Eating Ginger Skin

However, there are some potential disadvantages associated with eating ginger skin that need to be considered:

  • Pesticides – Non-organic ginger may contain pesticide residues on the skin, which you could ingest.
  • Bacteria – Ginger skin may harbor more bacteria compared to the flesh.
  • Tough texture – The skin has a fibrous, tougher texture than the softer inner flesh.
  • Strong flavor – The skin contains more concentrated essential oils, making it more strongly flavored.

For these reasons, some people prefer peeling ginger before eating it or using it in recipes. If the flavor or texture bothers you, you may want to remove the skin.

Ways to Eat Ginger Skin

Here are some tips on how you can incorporate ginger skin into your diet:

  • Add minced, unpeeled ginger to soups, curries, and stir fries.
  • Juice fresh ginger with the skin still on.
  • Blend peeled and unpeeled ginger into smoothies.
  • Dehydrate unpeeled ginger slices to make ginger chips.
  • Make a ginger skin tea by steeping the peel in hot water.
  • Leave the skin on ginger when making homemade ginger ale.
  • Use a vegetable peeler to thinly slice the skin of ginger root.

Cooking ginger skin for a prolonged period can soften the texture and mellow the flavor intensity. Opt for mincing, grating or blending the skin to avoid issues from the fibrous texture.

Should You Peel Ginger Before Juicing It?

When making fresh ginger juice, should you leave the skin on or peel it first? Here are some things to consider:

  • Nutrition – More nutrients will be retained if juicing with the ginger skin on.
  • Flavor – Skin on creates a more intensely flavored juice. Peeling dilutes the heat and zing.
  • Texture – The fiber content from the skin can make the juice more pulpy.
  • Appearance – Juice with the skin may have a darker, opaque look compared to peeled.

In the end, it comes down to personal preference. Try juicing ginger both ways to see which you enjoy more. Just be sure to wash the skin thoroughly if leaving it on.

Can You Eat Pickled Ginger Skin?

Pickled ginger, also called gari or sushi ginger, is a common palate cleanser served alongside sushi. It is made from very thinly sliced pieces of ginger that have been pickled in a brine of rice vinegar, sugar, and salt. But should you eat the skins of pickled ginger pieces?

The skin of commercially prepared pickled ginger is generally safe to eat. Here’s why:

  • The ginger is thoroughly washed and scrubbed before pickling.
  • The thin slices allow the pickling liquid to permeate the skin.
  • The pickling process softens the skin and reduces any tough texture.
  • The skin provides added fiber, vitamin C, and other nutrients.

However, if the pickled ginger skin seems unpleasantly fibrous or tough, feel free to remove it. The most important pieces are the softer, inner ginger slices.

Nutritional Profile of Ginger Skin vs. Flesh

Ginger skin and flesh both provide nutritional value, but with some differences. Here is a comparison of the nutrition found in ginger skin versus the flesh, per 100 grams (source: USDA):

Nutrient Ginger Skin Ginger Flesh
Calories 333 80
Protein 8.5 g 1.82 g
Fiber 27.2 g 2 g
Vitamin C 7.7 mg 5 mg
Magnesium 277 mg 43 mg
Phosphorus 407 mg 34 mg

As shown, ginger skin contains significantly more fiber, magnesium, and phosphorus compared to the inner flesh. It is also higher in calories and protein. However, the flesh has slightly higher vitamin C content.

Precautions With Ginger Skin

While ginger skin is edible, there are some precautions to keep in mind:

  • Wash thoroughly – Clean ginger skin first to remove dirt and reduce microbes.
  • Pesticide residue – Peel skin if ginger is not organic.
  • Oral allergy syndrome – Those allergic to banana or shellfish may react to ginger skin.
  • Medications – Ginger can interact with blood thinners and diabetes drugs.
  • Heartburn – The skin’s fiber may exacerbate gastrointestinal issues.

Additionally, introduce ginger skin gradually to allow your body to adjust to the high fiber content. Drink plenty of water to help move the fiber through your digestive tract.

The Bottom Line

Ginger skin is highly nutritious and contains beneficial compounds like gingerol. Eating small amounts of ginger skin may provide health benefits, such as improving digestion and reducing inflammation. However, take precautions by thoroughly washing it and removing it if it seems unpleasantly tough or fibrous. The skin can be consumed raw, dehydrated, minced, juiced, or pickled for versatile ways to add a nutrient boost to your diet.
