Also known as: red bell pepper, sweet pepper, bell pepper, Capsicum annuum

Overview

Red bell peppers, a variety of *Capsicum annuum*, are nutrient-rich vegetables known for their vibrant color and sweet flavor. They are particularly high in vitamin C, beta-carotene, and various antioxidants such as lycopene. Alongside their nutritional benefits, red bell peppers are commonly used in culinary applications, enhancing the flavor and nutritional content of numerous dishes. The primary bioactive compound, capsaicin, is noted for its potential health benefits, particularly in pain relief and metabolic enhancement. While extensive research exists on capsaicin, studies specifically highlighting the health benefits of whole red bell peppers are somewhat limited, primarily focusing on their nutritional content and antioxidant properties.

Benefits

Capsaicin in red bell peppers is linked to several health benefits. Meta-analysis shows that capsaicin supplementation can result in modest weight loss, with an approximate BMI reduction of -0.25 kg/m2 and body weight reduction of about -0.51 kg in obese individuals, particularly over studies lasting 6-12 weeks. Additional evidence suggests that capsaicin may help in reducing inflammation and improving metabolic health by enhancing fatty acid oxidation. However, the effect sizes are generally modest, and individual responses may vary. More pronounced effects are observed with longer supplementation durations.

How it works

Capsaicin operates mainly by activating the transient receptor potential vanilloid subtype 1 (TRPV1) channels, which subsequently stimulates the sympathetic nervous system. This activation can lead to increased energy expenditure and enhanced fat oxidation, thus potentially aiding weight management. The mechanism suggests that capsaicin influences metabolic pathways by promoting thermogenesis and fatty acid metabolism in the body.

Side effects

Red bell peppers are safe for general consumption. However, capsaicin supplements may cause gastrointestinal discomfort, including heartburn and stomach pain, in over 5% of users. Uncommon side effects (1-5%) can include sweating and flushing due to capsaicin's thermogenic properties. Serious adverse effects, such as allergic reactions, are rare (<1%). Caution is advised for individuals with gastrointestinal issues, as well as those taking certain medications, like blood thinners, due to potential interactions. Pregnant or breastfeeding individuals should consult a healthcare provider before using capsaicin supplements.

Dosage

There is no universally established effective dose for capsaicin; however, doses typically range from 0.1 to 10 mg per day, depending on the purpose. For weight loss, common dosages vary from 2 to 10 mg per day, though individual responses can differ. It is advised to consume capsaicin with meals to minimize gastrointestinal discomfort, and the choice of form (capsules, topical creams) should align with specific health goals. Taking capsaicin with fatty meals can enhance absorption, though there are no required cofactors needed for its effectiveness.

https://pubmed.ncbi.nlm.nih.gov/34676607/ – This systematic review and meta-analysis involving 762 participants across 15 studies found that capsaicin supplementation significantly reduced BMI and body weight. Effects were more pronounced in obese individuals and over longer study durations, though the authors noted high heterogeneity among included studies.
