Basic nutrition profile
Per 100 g of raw poblano peppers, the core macronutrient averages cluster around 40 calories, 0.3 g fat, 9 g carbohydrates, and about 1-2 g protein, with nearly all calories coming from carbohydrates rather than fat. This plate-friendly profile aligns well with weight-management and low-fat dietary patterns, especially when poblanos are grilled, roasted, or sautéed in minimal oil.
Dietary fiber in raw poblano peppers typically ranges from 1-2 g per 100 g, which supports digestive regularity and helps moderate blood-sugar swings after meals. This level of fiber, combined with almost no added sugars beyond the small amount of natural sugars inherent in the pepper, reinforces their role as a "clean" vegetable in diabetes-friendly and heart-healthy meal plans.
Vitamins and antioxidants
Vitamin C stands out in poblano peppers, with a 45 g raw serving providing roughly 85-110 mg, or up to about 120% of the Daily Value depending on source assumptions. This ascorbic acid content supports immune-cell function, collagen synthesis for skin and joints, and acts as a potent antioxidant that helps neutralize free-radical stress in tissues.
Vitamin A in the form of carotenoids also features prominently; a 100 g serving of poblano can deliver about 160 µg of vitamin A, or roughly 18% of the Daily Value. This nutrient duo of vitamin A and vitamin C supports eye health, mucosal integrity, and overall immune defense, which is why poblanos are often recommended in antioxidant-rich plant-based diets.
Additional micronutrients boosted by poblano peppers include small but meaningful amounts of potassium (around 145-175 mg per 100 g), which helps regulate blood pressure and electrolyte balance, and trace iron (about 0.5 mg per 100 g) that supports oxygen transport in hemoglobin. These minerals contribute to cardiovascular and metabolic health even in modest serving sizes, particularly when poblanos replace higher-sodium, lower-fiber ingredients in dishes.

Calorie and carb context
From a calorie-control standpoint, a single medium poblano pepper (roughly 45 g) clocks in at about 18 calories, with fat and protein each contributing less than 1 g and the bulk of energy coming from simple plant carbohydrates. This makes them ideal for low-calorie snacks, stuffed-pepper entrees, or as bulk-adding vegetables in casseroles without pushing daily energy above target ranges.
In terms of carbohydrates, the same 45 g serving yields about 4 g total carbs, with roughly 1 g of dietary fiber, so net carbs sit around 3 g per pepper. For those following carb-conscious or ketogenic-adjacent plans, using poblano as a vessel in dishes like chiles rellenos or "fajita" bowls can be reconciled with goals if fillings are kept low in refined starch and added sugars.
Health benefits and evidence base
Human nutrition studies and meta-analyses through 2023 highlight that diets rich in capsicum vegetables, including poblano, correlate with lower rates of chronic inflammatory conditions, partly due to high vitamin C and carotenoid content. A 2021 observational study pooling data from over 150,000 adults across six countries found that frequent consumption of non-spicy chili vegetables (including poblano and bell-type peppers) was associated with about a 12-15% lower all-cause mortality risk over an 8-year follow-up period.
Within pepper-based vegetables, poblanos also supply capsaicin, albeit at lower levels than jalapeños or habaneros, which may modestly enhance thermogenesis and satiety. Research published in 2022 noted that including mild capsaicin-containing peppers in meals led to an average self-reported reduction of about 10-15% in subsequent snack intake, likely due to subtle stimulation of satiety-linked gut peptides.
Mineral and micronutrient highlights
Beyond the headline vitamins, poblano peppers contribute useful background levels of trace minerals that support metabolic processes. A 100 g slice provides roughly 10 mg of magnesium (about 3% of the Daily Value) and small amounts of manganese, copper, and phosphorus, all of which play roles in bone formation, energy metabolism, and enzyme function.
One lesser-discussed but nutritionally relevant point is the presence of folate and B-complex vitamins in poblano peppers; a 100 g portion yields about 10 µg of folate (2% DV), 0.1 mg vitamin B6, and under 1 mg of niacin, which together support red-blood-cell formation, neurotransmitter synthesis, and carbohydrate metabolism. These micronutrients are easily lost in ultra-processed foods, so even modest servings of poblano can help close small dietary gaps in plant-forward diets.
When preparation changes nutrition
Raw poblano peppers retain the highest vitamin C and most heat-sensitive phytonutrients, while roasting or grilling can slightly reduce vitamin content but increase flavor and digestibility. A 2020 controlled-cooking study found that 10 minutes of moderate roasting reduced vitamin C by roughly 20% but actually increased the bioavailability of certain carotenoids, suggesting a net benefit when peppers are cooked gently.
On the other hand, heavy frying, especially in deep-fat or with cheese-laden fillings, can dramatically shift the nutritional profile away from the naturally low-fat baseline. For example, a traditional restaurant-style chile relleno using a breaded, fried poblano stuffed with cheese can push the dish into the 300-400 calorie range with 15-20 g of fat, largely due to oil and dairy rather than the pepper itself.
How to incorporate more poblano peppers into meals
One practical way to boost intake of poblano peppers is to add them to breakfast egg dishes, such as frittatas, scrambled eggs, or breakfast burritos, where they lend mild flavor without overpowering other ingredients. Roasting or grilling several peppers at once and storing them in the refrigerator allows for quick assembly of salads, grain bowls, and tacos with consistent nutrient density.
To maximize both flavor and health benefits, consider the following routine steps for using poblano peppers in rotation on your weekly menu:
- Rinse and dry 2-3 whole poblano peppers under cool water, then roast them over a gas flame or under a broiler until the skin is charred and blistered.
- Place the hot peppers in a covered bowl or sealed bag for 10-15 minutes to steam, loosening the skin for easier peeling.
- Peel off the blackened skin, remove the core and seeds, and slice the flesh into strips for "rajas" to add to soups, salads, or scrambled eggs.
- Use 1 stuffed poblano per person as a main-dish vegetable, filling it with a blend of beans, lean meat or tofu, and a small amount of cheese or nutritional yeast to keep added fat in check.
- Freeze leftover roasted poblano strips in a single layer on a tray, then transfer to a sealed container for use in future meals, preserving much of their vitamin content for up to 3 months.
How poblano peppers fit into common diets
For Mediterranean-style diets, poblano peppers work well alongside olive oil, legumes, and whole grains, contributing fiber, antioxidants, and mild spice without increasing saturated-fat intake. In vegetarian and vegan meal plans, they pair especially well with beans, lentils, and tofu to create iron- and protein-rich dishes that still remain low in calories per serving.
In low-carb and diabetic-friendly patterns, poblano peppers offer a low-glycemic way to add volume and nutrients; a 100 g serving adds only about 9 g of carbohydrates and 2 g of fiber, which can be easily accommodated within most daily carb limits. Professional dietitians surveyed in a 2023 U.S. practice survey reported that poblano-based vegetable dishes were among the top five recommended "swap-in" items for reducing refined-grain intake in Mexican-style meals.
Are poblano peppers safe for people with kidney disease?
Poblano peppers are generally kidney-friendly due to very low levels of sodium and moderate potassium content, but patients on strict potassium-restricted diets should account for the roughly 150 mg of potassium per 100 g
Key concerns and solutions for Poblano Peppers Shocking Nutrition
How many calories are in one poblano pepper?
A typical medium poblano pepper, weighing about 45 grams raw, contains approximately 13-18 calories, depending on exact size and moisture content. This serving includes roughly 4 g carbohydrates, less than 1 g of fat, and about 1 g of protein, with no cholesterol and negligible saturated fat.
Are poblano peppers good for weight loss?
Yes, poblano peppers are generally supportive of weight-loss diets because they are low in calories, high in water content, and rich in fiber, which promotes fullness between meals. Their mild heat from capsaicin can also slightly increase thermogenesis and reduce hedonic snacking when they are used as seasonings in otherwise low-calorie meals.
What vitamins are in poblano peppers?
Poblano peppers are particularly rich in vitamin C and vitamin A (from carotenoids), along with smaller amounts of vitamin E, vitamin K, and several B-vitamins including folate and vitamin B6. These vitamins collectively support immune function, vision, skin integrity, and energy metabolism, which is why poblano-heavy dishes often appear in antioxidant-focused meal plans.
Are poblano peppers inflammatory or anti-inflammatory?
Capsaicin-containing peppers such as poblano peppers are considered mildly anti-inflammatory because capsaicin can modulate inflammatory pathways and reduce oxidative stress markers in animal and in vitro models. Human trials through 2024 have shown that regular consumption of mild chili peppers correlates with lower levels of systemic inflammatory markers such as C-reactive protein, though the effect size is modest.
How much fiber is in poblano peppers?
A 100 g portion of raw poblano peppers contains about 1-2 g of dietary fiber, while a single medium pepper (45 g) provides approximately 0.7-1 g of fiber. This soluble and insoluble fiber mix supports bowel regularity, helps prevent constipation, and may improve short-term glycemic control when peppers are eaten with carbohydrate-rich foods.
Are poblano peppers low FODMAP?
Small portions of poblano peppers are generally considered low FODMAP; a serving of about 30-40 grams is typically tolerated by people following a low-FODMAP diet aimed at reducing irritable-bowel symptoms. However, larger servings or combinations with high-FODMAP ingredients (such as garlic or onions cooked alongside them) may trigger symptoms in sensitive individuals.
What is the difference between poblano and bell peppers nutritionally?
Poblano peppers and bell peppers are nutritionally similar in terms of calories, fat, and carbohydrate content, but poblanos tend to provide slightly more vitamin A and a trace of capsaicin, while bell peppers are usually richer in vitamin C per gram. Bell peppers can reach up to about 190 mg of vitamin C per 100 g, whereas poblanos land closer to 100-110 mg, a difference that may matter for strict antioxidant targets.
Can you eat poblano peppers every day?
Consuming poblano peppers daily is generally safe for most people, provided they are part of a balanced diet and not prepared with excessive added fats, salt, or cheese. Habitual intake is actually associated with better micronutrient status and modest cardiovascular benefits, but those with suspected chili or nightshade sensitivities should monitor symptoms and consult a clinician.
