Abstract:
Flavonoids may be natural components came from many vegetables and fruits. A variety of heath effects of these compounds were found. However, a few safety studies indicated that certain adverse effects of these compounds could influence on human health, which could involve genotoxic/carcinogenic effects or interaction with thyroid hormone biosynthesis. Isoflavones' estrogenic activity could influence on sexual development of young animals and children. Furthermore, flavonoids could inhibit the absorption of some nutrients, interact with certain drug pharmacokinetics and affect neurobehavioral development. In this paper, the potential toxicities of flavonoids from recently published papers were reviewed.
Insights
Flavonoids from fruits and vegetables offer health benefits but may pose risks. Research reviews potential toxicities, including genotoxicity, endocrine disruption, and nutrient interactions, for informed consumption.
Area of Science:
- Dietary compounds
- Phytochemicals
- Natural products
Context:
- Flavonoids are abundant in fruits and vegetables.
- Health benefits of flavonoids are widely recognized.
- Emerging safety concerns necessitate a comprehensive review.
Purpose:
- To review potential toxicities of flavonoids.
- To synthesize recent findings on adverse health effects.
- To provide an evidence-based overview of flavonoid safety.
Summary:
- Flavonoids exhibit genotoxic/carcinogenic potential and can interfere with thyroid hormone synthesis.
- Isoflavones possess estrogenic activity, impacting sexual development in young organisms.
- Flavonoids may inhibit nutrient absorption, alter drug pharmacokinetics, and affect neurobehavioral development.
Impact:
- Informs consumers and healthcare professionals about potential flavonoid risks.
- Guides future research on flavonoid safety and risk assessment.
- Contributes to evidence-based dietary recommendations regarding flavonoid intake.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
