Why it scores 66
Red bell peppers achieve a 'Good' FoodScore of 66 out of 100, largely driven by their strong micronutrient profile and unprocessed nature. The most significant positive impact comes from its high vitamin C content, providing 157% of the Daily Value per 100g, which contributes a substantial bonus. Additionally, its status as a minimally processed whole food (NOVA class 1) adds a significant 10-point bonus, aligning with dietary guidelines that emphasize whole, unprocessed foods. The presence of folate, contributing 12% of the Daily Value, also provides a smaller bonus. Red bell peppers benefit from having no penalties, as they contain 0g of added sugar, 0mg of sodium, and negligible saturated fat. While its fiber content at 1.16g per 100g is present, it's not high enough to earn a significant bonus. To achieve a higher score, red bell peppers would need to provide higher amounts of fiber or other beneficial micronutrients beyond vitamin C and folate, or a more substantial protein contribution, though this is not typical for a non-starchy vegetable.
Health benefits
What the nutrients in bell pepper red actually do for you, grounded in established dietary science.
Immune System Support
Red bell peppers are an excellent source of vitamin C, a key nutrient for immune system function. A 100g serving provides 157% of the Daily Value for vitamin C, far exceeding daily requirements. This vitamin acts as an antioxidant, protecting cells from damage, and is crucial for the production of white blood cells that fight infections. Regular intake of vitamin C-rich foods like red bell peppers can help maintain a robust immune response. While vitamin C is vital, a balanced diet with other nutrients is also essential for overall immune health.
Antioxidant Protection
Beyond vitamin C, red bell peppers contain various antioxidant compounds that help combat oxidative stress in the body. These antioxidants, including carotenoids like beta-carotene (which the body converts to vitamin A) and other phytonutrients, work to neutralize free radicals. This protective action is important for reducing cellular damage and may contribute to a lower risk of chronic diseases. Including a variety of colorful vegetables like red bell peppers in your diet ensures a broad spectrum of these beneficial compounds.
Supports Healthy Vision
The vibrant red color of bell peppers indicates the presence of beneficial compounds, including those that support eye health. While the specific vitamin A percentage isn't listed, red bell peppers are known to contain carotenoids like beta-carotene, lutein, and zeaxanthin. These compounds accumulate in the retina and can help protect the eyes from oxidative damage and filter harmful blue light. Regular consumption of foods rich in these carotenoids is associated with maintaining good vision as you age. However, other foods like leafy greens are also crucial for comprehensive eye health.
Promotes Red Blood Cell Formation
Red bell peppers contribute to the body's ability to form healthy red blood cells due to their folate content. A 100g serving provides 12% of the Daily Value for folate. Folate is a B vitamin essential for DNA synthesis and cell division, processes critical for the production of red blood cells. Adequate folate intake helps prevent certain types of anemia and supports overall cellular health. While not the highest source, red bell peppers can be a valuable part of a diet rich in folate-contributing foods.
Red bell peppers score a solid 66/100, primarily due to their exceptional vitamin C content and status as a minimally processed whole food.
How to eat it
Red bell peppers are a versatile and popular vegetable in the US diet, often consumed raw, roasted, grilled, or stir-fried. Their sweet flavor and crisp texture make them a favorite for adding color and nutrients to a wide range of dishes.

Things to keep in mind
Red bell peppers are generally considered safe for consumption by most individuals and are not commonly associated with allergies. Some people with a sensitivity to the nightshade family of vegetables may experience mild digestive discomfort, but this is rare. There are no widely documented drug interactions or specific populations for whom red bell peppers are cautioned against at normal serving sizes. Their low FODMAP content also makes them generally well-tolerated for individuals with irritable bowel syndrome (IBS).
Yes, red bell peppers are very healthy. They score 66/100 on FoodScore, indicating a 'Good' nutritional profile. They are notably rich in Vitamin C, providing 157% of the Daily Value per 100g, and are a minimally processed whole food (NOVA 1). They contain no added sugar, sodium, or saturated fat, making them a nutrient-dense choice for a balanced diet.
Are red bell peppers good for weight loss?
Red bell peppers can be a beneficial addition to a weight loss diet. They are very low in calories (0 per 100g) and contain no fat or added sugar. Their high water content and fiber (1.16g per 100g) can contribute to satiety without adding significant calories, helping you feel full. They are a great way to add volume and nutrients to meals.
Are red bell peppers processed?
No, red bell peppers are classified as a NOVA 1 food, meaning they are unprocessed or minimally processed. This indicates they are consumed in their natural state or have undergone minimal processing like washing or cutting, without the addition of unhealthy ingredients. This aligns with dietary recommendations to prioritize whole, unprocessed foods.
What's the best way to cook red bell peppers to preserve nutrients?
To preserve the most nutrients, especially heat-sensitive Vitamin C, it's best to eat red bell peppers raw or lightly cooked. Steaming, stir-frying for a short duration, or quick grilling are good options. Over-boiling or prolonged high-heat cooking can reduce their vitamin content. Enjoying them raw in salads or as a snack is an excellent way to maximize their nutritional benefits.
Can I substitute green bell peppers for red bell peppers?
Yes, you can substitute green bell peppers for red bell peppers in most recipes, but there are some differences. Green bell peppers are simply unripe red bell peppers, so they have a slightly more bitter taste and firmer texture. Nutritionally, red bell peppers tend to have higher levels of Vitamin C and Vitamin A (from beta-carotene) compared to green ones. The choice depends on your preference for flavor and desired nutrient profile.
Do red bell peppers help with blood sugar control?
Red bell peppers can contribute to healthy blood sugar management. They have a very low glycemic load due to their minimal carbohydrate content and absence of added sugars. Their fiber content, though not exceptionally high at 1.16g per 100g, can also help slow down sugar absorption when consumed as part of a meal. Including non-starchy vegetables like bell peppers helps create balanced meals that support stable blood glucose levels.
What are the main vitamins in red bell peppers?
The main vitamins in red bell peppers are Vitamin C and Folate. A 100g serving provides an impressive 157% of the Daily Value for Vitamin C, making it one of the best dietary sources. It also offers 12% of the Daily Value for Folate, a B vitamin important for cell function. While other vitamins are present, these two are the most significant contributors to its nutritional value.
