Paprika
Also known as: Paprika, Sweet Pepper, Bell Pepper, *Capsicum annuum L.*
Overview
Paprika is a spice derived from the dried fruit of the sweet pepper plant (*Capsicum annuum L.*) and is renowned for its vibrant red color and diverse carotenoid content, including capsanthin, β-carotene, β-cryptoxanthin, and zeaxanthin. As a carotenoid-rich dietary supplement, paprika is lauded for its antioxidant properties, which can potentially mitigate cellular oxidative damage. In addition to its culinary applications, paprika's carotenoids are studied for their health benefits, which include improved bone quality and reduced cancer risk. The body of research on paprika carotenoids is expanding, showcasing randomized controlled trials and meta-analyses that underline their importance as functional foods.
Benefits
Evidence-based benefits of paprika include significant improvements in bone health, particularly in postmenopausal women, where a study demonstrated that supplementation with paprika carotenoid extract resulted in reduced markers of bone resorption (TRACP-5b) over 24 weeks. Furthermore, a meta-analysis found that high dietary intake of carotenoids, including those from paprika, correlates with lower risks of several cancers, such as gastric and colorectal cancers, with notable odds ratios indicating protective effects. Overall, postmenopausal women have shown notable benefits from paprika supplementation regarding bone quality maintenance.
How it works
Paprika carotenoids function primarily as antioxidants, safeguarding cells against oxidative stress and damage. They exert effects on bone metabolism by inhibiting the activity of osteoclasts, the cells responsible for bone resorption, leading to decreased bone loss. These carotenoids interact with key enzymes involved in bone turnover and may influence immune responses through their antioxidant capabilities, thereby supporting overall skeletal health.
Side effects
Paprika carotenoids are generally safe for consumption in dietary amounts, with limited data identifying common side effects (>5%). Uncommon side effects (1-5%) and rare side effects (<1%) are not well-documented, indicating a favorable safety profile. There is no strong evidence of drug interactions, although caution is recommended when taking with other antioxidants or medications that could interact with carotenoids. Particularly vulnerable groups, such as pregnant or breastfeeding women, should seek medical advice prior to supplementation. Individuals with known allergies to peppers or certain medical conditions should also consult healthcare professionals before use.
Dosage
The minimum effective dose of paprika carotenoid extract (PCE) for bone health is 20 mg per day, approximately equivalent to 1.4 mg of total carotenoids. This dosage corresponds to results observed in studies focusing on bone resorption markers. While optimal dosage ranges are not extensively studied beyond this threshold, maintaining continuous daily supplementation is advised based on current findings. Notably, the absorption of these carotenoids may be enhanced when consumed with dietary fats, as they are lipophilic compounds. No defined maximum safe dose exists, necessitating further investigation into upper limits of effectiveness and safety.
FAQs
