The carob tree (Ceratonia siliqua L.) is a Mediterranean plant whose fruits, known as carob pods, are rich in bioactive compounds. These compounds include dietary fibres, polyphenols, natural sugars, and essential minerals, which offer various health benefits. This study reviews the nutritional and bioactive properties of carob pods and their derivatives. A comprehensive literature review was conducted, focusing on studies that analyze the composition and health benefits of carob. Carob pods contain both soluble and insoluble dietary fibers, which aid in digestion, regulate bowel movements, control appetite, and reduce cholesterol levels. Polyphenols, such as flavonoids and tannins, provide antioxidant properties that neutralize free radicals and protect against oxidative stress, thereby reducing inflammation. The natural sugars in carob, including sucrose and fructose, serve as a natural energy source with a lower impact on blood sugar levels compared to refined sugars. Essential minerals like calcium, potassium, magnesium, and iron support various physiological functions, including bone and heart health. Carob's anti-hyperglycemic properties help regulate blood sugar levels, beneficial for diabetes management. Its antioxidant properties reduce the risk of chronic diseases such as cardiovascular diseases and certain cancers, while its anti-inflammatory properties can alleviate conditions like arthritis and inflammatory bowel disorders. Carob-based products, such as carob flour and carob syrup, hold significant potential as functional food ingredients due to their nutritional and bioactive properties. Applications include its use as a chocolate substitute, food additive, and dietary supplement aimed at improving digestive and metabolic health. Thus, carob and its derivatives represent a valuable resource for the food industry and health-conscious consumers seeking to enhance their health through nutrition.
