The Basics on Ginger

The pleasantly spicy, peppery, and ever-so-slightly sweet ginger rhizome, or rootstalk, isnative to several Asian countries(including China, India, and Japan) and has been a staple incooking and herbal medicineforthousands of years.

While ginger (zingiber officinale) may be most widely known for its anti-nausea properties and ability to relieve various gastrointestinal symptoms, research suggests its benefits are much more widespread. Liketurmeric(another rhizome), ginger may offer several metabolic benefits thanks to its manybioactive phenolic compounds, which include gingerols, shogaols, and zingerone. These compounds are responsible for ginger’s zesty flavor and have been shown to have anti-inflammatory, cardioprotective, glucose-regulating, and antioxidant properties.

Fresh, powdered, or dried ginger is also an affordable way to add health benefits and flavor to dishes like stir-fries, dressings, curries, soups, and smoothies—all while providing minimal calories and carbs, and no added sugar. One teaspoon of grated, raw ginger rootcontains just1.6 calories, 0.4 grams of carbohydrates, and zero grams of sugar.

One of the Main Health Benefits of Ginger is Its Metabolic Punch

Two key metabolic perks of ginger are its antioxidant and anti-inflammatory properties. These are important, as oxidative stress (caused by an imbalance of free radicals and antioxidants in the body) and chronic inflammation are thought topave the way for metabolic disorders. For instance, oxidative stress can trigger cellular damage and inflammation. In turn, this inflammation can drive issues like insulin resistance, diabetes, andheart disease.

Several bioactive compounds may be responsible for these antioxidant and anti-inflammatory effects of ginger. For example, gingerols and shogaols have beenshown to impede the synthesis of pro-inflammatory molecules (i.e., prostaglandins and cytokines) and downregulate pathways that turn on inflammation-driving genes.

More human studies are needed to demonstrate these benefits. Still, several randomized controlled trials (RCTs; often considered the gold standard of research) suggest that supplementing with ginger curbs symptoms of osteoarthritis and rheumatoid arthritis—conditions associated with inflammation—without adverse effects. In one RCT, taking 500 milligrams (mg) of ginger powder capsules daily for three months was associated with reduced proinflammatory cytokines. In another trial, taking 1,500 mg of ginger powder daily for three months was associated with increased expression of FoxP3 genes, which can help keep excessive inflammation in check.

Ginger may also benefit blood sugar levels, triglyceride and cholesterol levels, and body weight. Though more research is needed to confirm the optimal dose for these benefits, ameta-analysis of 14 studies found that ginger supplementation was associated with significantly decreased body weight, waist-to-hip ratio, and insulin resistance, and significantly increased HDL cholesterol in overweight people and those with obesity. Additionally,an RCTexamining Type 2 diabetes patients found that those who received 2 grams of ginger powder per day experienced significantly reduced fasting blood sugar, hemoglobin A1c, apolipoprotein B (a marker of potentially harmful blood lipids), and malondialdehyde (a marker of lipid oxidation) after three months compared to a placebo group. Anda clinical trial with the same dose showed similar blood glucose benefits and an improvement in the LDL to HDL cholesterol ratio.

While daily ginger consumption is safe, some sources suggest capping your intake at 4 g per day to avoid GI side effects such as indigestion, which may occur with high doses.For reference, 1 g equals ½ tsp of powdered ginger or 1 tsp of grated, raw ginger. If you take a ginger supplement instead of fresh or powdered ginger, select a brand without added ingredients and follow dosage instructions. If you’re pregnant ortaking certain medications such as blood thinners, anti-hypertensives, diabetic, or blood-pressure medications, consult your healthcare provider before supplementing with ginger.

Ginger Buying Advice

Various ginger options exist at your local grocery store: Fresh ginger, ground ginger (or powdered ginger), and ginger tea bags are all good picks. Ones to skip: Candied or crystallized ginger, pickled sushi ginger, ginger ale, and ginger beer, which typically contain added sugars.

While exact levels of beneficial phenolic compounds may be marginally different in fresh versus powdered ginger (e.g., gingerols areslightly reducedin powdered compared to fresh, while shogaols are more abundant), somenutrition and wellness expertsconsider both beneficial. Researchalso shows that ginger tea may be an effective way to quickly absorb beneficial ginger compounds, including gingerols. Since the benefits are similar, choose a form based on your preference.

• Fresh ginger root from the produce section of your grocery store is ideal for adding a potent punch of flavor to stir-fries,dressings, sauces, andsmoothies, or for homemade ginger tea. If you’re not a fan of grating, slicing, or chopping, you can find organic, minced ginger from brands likeThe Ginger Peopleto easily dollop into recipes.
• Ginger powder from the spice aisle also works well in recipes and is particularly handy for baked goods and dessertswhere you want a uniform texture. It’s also great in smoothies and stirred into yogurt oroatmeal alternatives. While it’s more concentrated than fresh ginger, it doesn’t have as much of a bite.
• Keep a box of store-bought ginger tea bags on hand to reap ginger’s benefits for minimal effort. Brands likeTraditional MedicinalsandYogiare good options.

When buying fresh ginger: Look for a “hand” (i.e., a branching ginger rhizome) that’s firm to the touch, smooth, and has a pleasant spicy aroma. Avoid ginger with soft spots, cracked or wrinkly skin, or visible mold—all signs the rhizome is past its prime.

Tips for Using and Storing Ginger

Keep it simple:Fresh ginger doesn’t require any fancy preparation. To use ginger in stir-fries, dressings, marinades, sauces, and soups, simply grate off the amount you wish to use and add to your dish. For smoothies or creamy soups, toss a knob of ginger right in the blender.

Store whole ginger in the fridge or freezer:First rinse fresh ginger under warm water while wiping off any dirt with your fingers or a vegetable brush, then pat dry with a paper towel. Store in a sealed plastic bag or airtight container in your refrigerator’s crisper drawer for about three weeks. When you’re ready to use it, cut off only what you need. You can also keep ginger wrapped in plastic and placed in an airtight container in the freezer for up to three months—grate it straight from the freezer without defrosting.

Make a versatile ginger paste:To save time later, make your ownginger pasteby peeling ginger (pro tip:use a spoon) and grating or pureeing it in a food processor. Dollop individual portions of ginger paste into a silicone ice cube tray, place the whole tray or put it in a zip-top freezer bag in a thin layer, and freeze for up to 6 months. Pop out individual portions of ginger as needed.

Eat it raw or cook it—both are healthy: Research suggests that heating raw ginger (i.e., in cooking or making tea) reduces its ability to scavenge certain types of free radicals and increases its ability to scavenge other types—likely due to the conversion of gingerols to shogaols. Switch things up to get the broadest range of benefits.

Ditch powdered ginger after two years.For optimal freshness, use powdered ginger within two years. Store in an airtight container in a cool, dry place.

Ideas for Eating Ginger

Ginger can complement sweet and savory flavor profiles alike. Here are some delicious ways to use it:
