What Is Chili Oil?

Chili oil is a spicy condiment produced by infusing oil—often vegetable, sesame, or olive oil—with dried chili peppers and occasionally other flavoring agents such as garlic or ginger. Its origins are rooted in Asian cuisines, especially Chinese, Korean, and Thai traditions, but it is now enjoyed worldwide. The ingredient responsible for chili oil’s characteristic heat and many of its health benefits is capsaicin, a bioactive compound found in chili peppers.

Chili Oil Nutrition Facts

While chili oil is primarily composed of fats, the inclusion of chili peppers and spices contributes valuable bioactive compounds, antioxidants, and vitamins. The nutritional profile per tablespoon (approximate, varies by recipe):

Nutrient	Amount
Calories	120 kcal
Total Fat	14 g
Saturated Fat	1.5 g
Vitamin E	~2% DV
Capsaicin	Varies (mg)
Carotenoids	Trace
Antioxidants	Present
Carbohydrates	<1 g

Capsaicin and other phytochemicals, such as carotenoids and flavonoids, are largely responsible for chili oil’s health-boosting properties.
Most calories in chili oil come from unsaturated fats, depending on the oil used.

9 Incredible Health Benefits of Chili Oil

Research continues to uncover a wide range of benefits associated with consuming chili oil. Here are the top science-backed advantages:

1. Rich In Antioxidants

Chili oil contains carotenoids, capsaicinoids, and flavonoids—potent antioxidants that fight cell damage caused by free radicals.
Dietary antioxidants help reduce the risk of chronic illnesses—such as cardiovascular disease and cancer—by protecting your body’s cells from oxidative stress.

2. Anti-Inflammatory Properties

The capsaicin in chili oil has strong anti-inflammatory effects. It inhibits the release of pro-inflammatory compounds, helping alleviate chronic inflammation, which is linked to conditions like arthritis, diabetes, and heart disease.
Regular (but moderate) consumption may decrease markers of inflammation and benefit those with inflammatory disorders.

3. Supports Heart Health

Several studies have found that people consuming chili peppers and capsaicin-rich foods regularly show a lower risk of cardiovascular diseases, heart attacks, and strokes.
Capsaicin can help lower blood cholesterol and triglyceride levels and improve blood circulation.
One large study showed chili eaters had a significantly reduced risk of heart disease-related deaths compared to non-eaters.

4. Metabolism And Weight Management

Capsaicin in chili oil increases thermogenesis—the process by which your body produces heat—leading to more calories burned, even at rest.
Chili oil can promote fat oxidation and suppress appetite, supporting efforts for weight loss or weight maintenance.
One meta-analysis suggests incorporating chili-based condiments can contribute to modest but meaningful reductions in body weight over time.

5. Pain Relief

Topical and dietary capsaicin is shown to provide pain relief by inhibiting substance P—a neurotransmitter that carries pain signals to the brain.
This makes chili oil useful not only as a food, but also as a massage oil for people with muscle soreness, joint pain, or arthritis.

6. Promotes Healthy Digestion

Capsaicin stimulates secretion of digestive fluids and boosts enzyme activity, aiding in the breakdown and absorption of nutrients.
Helps prevent or relieve constipation and may reduce uncomfortable symptoms of indigestion.
Some research indicates capsaicin can help balance gut motility and encourage the growth of healthy gut bacteria.

7. Antimicrobial Effects

Chili oil is rich in phytonutrients that have demonstrated the ability to inhibit the growth of certain bacteria and fungi.
This may contribute to food safety and help fight off foodborne pathogens, especially in traditional preservation methods.

8. Boosts Immune Function

The combination of vitamin E, capsaicin, and other antioxidants improves immune defense mechanisms.
Regular but moderate chili oil consumption may enhance resistance to infections and support faster recovery.

9. Improved Mood and Wellbeing

Eating spicy foods such as chili oil triggers the release of endorphins and serotonin, boosting your mood and potentially reducing symptoms of stress and depression.
This might explain why spicy food lovers often report feeling energized and happier after a meal.

Side Effects And Precautions

Although chili oil offers impressive health benefits, it’s important to use it safely and in moderation.

Stomach irritation: Overconsumption may cause heartburn, acid reflux, or aggravate digestive disorders such as gastritis or ulcers.
Hemorrhoids: Excessively spicy food can worsen symptoms in people with hemorrhoids.
Allergic reactions: Individuals allergic to chili peppers should avoid chili oil entirely.
Medication interactions: Capsaicin may interact with some medications. Consult your physician if you’re taking blood thinners or other prescription drugs.
Children and sensitive individuals: Use caution, as children and those with a low spice tolerance may experience discomfort.

How To Use And Make Chili Oil At Home

Chili oil’s intense flavor and vibrant color can elevate almost any dish. Here’s how to harness its culinary and health benefits:

Popular Culinary Uses

Drizzle on noodles, dumplings, stir-fries, and soups.
Add to salad dressings or marinades for an extra kick.
Mix with vegetables or use as a flavorful finishing oil for meats, tofu, and seafood.
Blend into dips or sauces for sandwiches and wraps.

Simple Homemade Chili Oil Recipe

Heat 1 cup of neutral-flavored oil (such as avocado, canola, or peanut oil) in a pan until just shimmering—not smoking.
Pour oil over 2-3 tablespoons of dried chili flakes in a heat-resistant bowl. Optionally, add minced garlic, a slice of ginger, or Sichuan peppercorns for added aroma.
Let cool, then strain and pour into a sterilized glass jar. Store in the refrigerator for up to one month.

Tips For Safe Consumption

Start with small amounts, particularly if you are not accustomed to spicy food.
Store homemade chili oil in a cool, dark place and refrigerate after opening to prevent spoilage.
Monitor for any signs of digestive discomfort or allergies, and reduce intake if needed.

Frequently Asked Questions (FAQs)

1. Is chili oil healthy for daily use?

Moderate consumption of chili oil may contribute to better metabolic, cardiovascular, and digestive health. However, it should be balanced with a diet low in saturated fat and consumed in reasonable amounts to avoid potential side effects.

2. Can chili oil help with weight loss?

Chili oil, when included as part of a calorie-controlled diet, can aid in weight management by boosting metabolism and promoting fat oxidation, thanks to capsaicin.

3. Does chili oil irritate the stomach?

For most healthy individuals, moderate quantities are unlikely to cause harm. However, those with acid reflux, ulcers, or sensitive digestive systems should use it cautiously to avoid irritation.

4. Are there different types of chili oils?

Yes. Chili oil can be made with a variety of chili peppers and oil bases, resulting in different heat levels, aromas, and flavors. Asian-style chili oils often contain additional spices for complexity.

5. Can I use chili oil topically?

While some medicinal capsaicin oils are designed for topical use to relieve pain, culinary chili oil is intended for food and may not be appropriate or safe for application on skin.
