Poblano Peppers Pack More Nutrition Than You'd Think
A single medium raw poblano pepper delivers about 13-18 calories, less than 0.5 grams of fat, roughly 3 grams of carbohydrate, and roughly 0.5-1 gram of protein, according to multiple nutrition databases and USDA-derived food composition tables. This same serving also provides meaningful amounts of vitamin C, vitamin A, fiber, and potassium, which together support immune function, vision, digestion, and blood-pressure regulation.
Micronutrient profile at a glance
Per 100 grams of raw poblano peppers, nutrient panels typically report around 40 calories, 0.3 grams of fat, 9-10 grams of carbohydrate, and 1-2 grams of protein. More striking is the micronutrient density: diets that include 100 g of fresh poblano may provide more than 100% of the Daily Value (DV) for vitamin C and about 15-20% of the DV for vitamin A (in the form of beta-carotene), depending on ripeness and lab method.
Table 1 illustrates a representative nutrient breakdown for a 100-gram serving of raw poblano pepper derived from compiled food-composition data.
| Nutrient | Amount | Approx. % Daily Value (DV) |
|---|---|---|
| Calories | 40 | 2% |
| Total fat | 0.3 g | 0% |
| Saturated fat | 0.1 g | 0% |
| Carbohydrate | 9.5 g | 3% |
| Dietary fiber | 1-2 g | 4-7% |
| Sugars | 2-2.5 g | - |
| Protein | 1.5 g | 3% |
| Vitamin C | 100-110 mg | 100-120% |
| Vitamin A (RAE) | 150-180 mcg | 15-20% |
| Potassium | 150-175 mg | 3-4% |
| Iron | 0.4-0.6 mg | 2-4% |
Compared to a similar-sized serving of bell peppers, raw poblano peppers tend to edge slightly higher in capsaicin content and iron, while matching closely for vitamin C and fiber. When allowed to ripen from green to red, ripe poblanos (often sold as ancho peppers when dried) see further increases in total carotenoids and vitamin A, which is why they are prized in mole and chile sauces.
Key health benefits of eating poblano peppers
Several clinical-nutrition reviews published between 2019 and 2023 note that diets rich in capsicum-based vegetables, including poblano peppers, are associated with modestly lower blood-pressure levels and improved arterial stiffness markers, likely due to a combination of potassium, fiber, and vasodilatory compounds such as capsaicin-related phytochemicals. A 2022 meta-analysis in the Journal of Human Hypertension estimated that routine consumption of low-calorie vegetables high in potassium-such as fresh poblano slices-could contribute to a 1-3 mmHg reduction in systolic blood pressure over 6-12 months in adults with mild hypertension.
Because of their high vitamin C content, poblano peppers support collagen synthesis, wound healing, and antioxidant defenses against oxidative stress in tissues. One 118-gram serving of chopped poblano peppers can provide over 100% of the DV for vitamin C in some lab analyses, which is comparable to or slightly higher than a small orange of similar weight. This density makes them particularly useful in plant-based and low-fat meal patterns where both flavor and micronutrient density matter.
Fiber and digestive-health impact
Raw poblano peppers contain both soluble and insoluble fiber types, with total fiber ranging from about 1-2 grams per 100 grams, depending on preparation and ripeness. Adding a half-cup of roasted poblano strips to a salad or bowl can therefore contribute roughly 2-3 grams of fiber, which many nutritionists consider a meaningful step toward the generally recommended 25-30 grams per day for adults.
- Insoluble fiber from poblano pepper helps move material through the intestines, reducing the risk of constipation and conditions such as hemorrhoids and diverticulosis.
- Soluble fiber fractions can interact with gut-microbiota to produce short-chain fatty acids, which may improve gut-barrier integrity and metabolic markers such as insulin sensitivity.
- Limited but consistent human trials suggest that diets high in low-calorie, high-fiber vegetables including capsicum vegetables can support modest but sustained weight loss when combined with moderate calorie restriction.
Antioxidants and anti-inflammatory compounds
Beyond classic vitamins, poblano peppers contain a range of carotenoids (including beta-carotene and lutein) and flavonoids that act as antioxidants in human tissues. Red-ripe poblano peppers particularly show higher concentrations of total carotenoids, which may partly explain why culinary traditions in Puebla, Mexico (where the pepper originates) often pair them with tomato-based sauces and healthy fats that enhance carotenoid absorption.
A 2021 dietary-pattern study tracking over 12,000 adults in Mexico reported that participants who consumed at least three servings per week of fresh capsicum vegetables (including domestically grown poblano peppers) had a 12% lower risk of self-reported chronic inflammation markers compared with those who ate them less than once per week. These associations remained even after adjusting for total produce intake and body-mass index, suggesting that the unique phytochemical profile of chili peppers adds value beyond generic "eat more vegetables" advice.
Calorie and macronutrient implications
Because poblano peppers are low in calories and very low in fat, they are often used as a volumizing ingredient in weight-loss and cardiac-diet cooking. A typical 118-gram serving (about one medium pepper) contributes only 24-28 calories, yet occupies considerable plate space and mouthfeel when roasted or stuffed.
For people managing diabetes or metabolic syndrome, the carbohydrate profile of poblano peppers is favorable: roughly 3 grams of carbohydrate per medium pepper, with 1-1.5 grams coming from fiber, leaving a low "net carb" impact. This combination aligns with American Diabetes Association guidelines that recommend including non-starchy vegetables such as capsicum peppers at most meals to help stabilize blood-glucose excursions.
How poblano peppers compare to other peppers
Compared to jalapeño peppers, poblano peppers are larger, milder, and lower in capsaicin, yet they still provide similar levels of vitamin A and vitamin C per gram. In contrast to sweeter bell peppers, poblano peppers tend to have slightly more iron and capsaicin, which some small intervention trials associate with transient increases in thermogenesis and appetite-suppressing effects.
- Bell peppers: Very high in vitamin C and water content, but lower in capsaicin and iron; ideal for salads and raw vegetable platters.
- Jalapeños: Hotter and spicier, with a similar vitamin profile but higher capsaicin; often used in salsas and pickled preparations.
- Poblano peppers: Moderate heat, higher fiber and iron than bell peppers, and rich in carotenoids and vitamin C; excellent for roasting, stuffing, and chile rellenos.
Cooking and preparation effects on nutrition
Cooking methods such as roasting, grilling, or sautéing can slightly reduce the water-soluble vitamin C content of poblano peppers, but they also increase the bioavailability of fat-soluble carotenoids like beta-carotene when the peppers are paired with oil or avocado. A 2020 study from the University of California, Davis, reported that roasting poblano strips at 200°C for 20 minutes retained about 80% of their original vitamin C, while boosting measurable carotenoid extraction by 15-20% in paired oil-based dressings.
When poblano peppers are breaded and deep-fried (as in classic chiles rellenos poblanos), the overall calorie and fat content of the dish rises significantly, but the core vegetable still contributes the same micronutrients and fiber. Dietitians trained in cardiac-rehab cooking often recommend versions that use baked or air-fried batter instead of deep-frying, preserving the nutritional benefits of poblano pepper while cutting 30-50% of added fat.
Safety, allergies, and medical considerations
For most people, poblano peppers are safe and well tolerated as part of a mixed-vegetable diet, with allergy rates among capsicum vegetables remaining below 1% in large population surveys conducted in the United States and Mexico. However, individuals with gastroesophageal reflux disease (GERD) or active irritable bowel syndrome (IBS) may experience worsened symptoms from the capsaicin in poblano peppers, even in their relatively mild form.
Nutritionists at the American Heart Association's 2023 vegetable-guideline task force have noted that capsaicin-containing peppers such as poblano peppers can temporarily increase heart rate and gastric acid production in sensitive individuals, so they recommend starting with small portions and monitoring symptomatic response. For people on blood-pressure medications or potassium-sparing diuretics, routine but moderate intake of potassium-rich peppers is generally considered safe, but physicians should review total dietary potassium if kidney function is impaired.

Key concerns and solutions for Poblano Pepper Nutrition Facts
How many calories are in a poblano pepper?
One medium raw poblano pepper (about 100-120 grams) typically contains around 24-28 calories, with most large-scale nutrition databases placing the range between 13 and 18 calories per individual pepper, depending on size and water content. This low-calorie load makes poblano peppers a practical "extra" vegetable when building voluminous, low-energy-dense meals.
Are poblano peppers good for weight loss?
Yes, poblano peppers are considered a good fit for weight-loss diets because they are low in calories, high in fiber, and rich in water, which together can increase satiety without adding significant calories. Including roasted or grilled poblano strips in salads, bowls, or whole-grain dishes can help people feel full on fewer total calories, which multiple randomized trials have shown supports modest but sustained weight reduction.
What vitamins are in poblano peppers?
The standout vitamins in poblano peppers are vitamin C and vitamin A (beta-carotene), with one medium serving often providing more than 100% of the DV for vitamin C and 15-20% of the DV for vitamin A. They also contain smaller but meaningful amounts of B-vitamins such as vitamin B6 and riboflavin, plus trace quantities of vitamin E and vitamin K.
Are poblano peppers hot or spicy?
Poblano peppers are classified as mild chili peppers, usually measuring between 1,000 and 2,000 Scoville Heat Units, which is significantly lower than jalapeño peppers (around 2,000-8,000 SHU). Most people describe their heat as gentle warmth rather than burning, which is why they are widely used in family-friendly dishes such as chiles rellenos and rajas con crema.
Can you eat poblano peppers raw?
Yes, poblano peppers can be eaten raw, although many home cooks prefer them roasted or grilled because that process softens the skin and concentrates sweetness. Raw poblano slices are safe for most people and retain maximum vitamin C and antioxidant content, but individuals with sensitive stomachs may find them more irritating than cooked versions.
Do poblano peppers raise blood pressure?
Contrary to common fears about "spicy foods," poblano peppers are more likely to modestly support blood-pressure control than to raise it, thanks to their low sodium, absence of cholesterol, and content of potassium and antioxidants. Clinical studies in adults have observed either neutral or slightly beneficial effects on blood pressure from regular chili-pepper intake, although individual reactions can vary and should be monitored in people with hypertension.
