Scientific Proof of the Nutritional and Health Benefits of Orange Peels

This article presents scientific evidence supporting the nutritional and health benefits of orange peels. Orange peels are often discarded as waste, but recent research has highlighted their rich content of fiber, vitamins, disease-fighting polyphenols, and the potential protective effects of limonene against skin cancer. The findings discussed in this article contribute to our understanding of orange peels as a valuable source of bioactive compounds with potential health benefits.

  1. Introduction: Orange peels, which are typically discarded, have gained attention for their potential nutritional and health benefits. This document aims to provide scientific evidence supporting these claims, focusing on their fiber content, vitamin composition, polyphenol profile, and the potential role of limonene in skin cancer prevention.

  2. Fiber Content: Orange peels are a rich source of dietary fiber, which plays a crucial role in digestive health and maintaining a healthy weight. The high fiber content of orange peels can contribute to satiety, aid in regulating blood sugar levels, and support a healthy gastrointestinal system.
