Effect of the fruits mentioned in the Holy Qur'an in improving cardiovascular diseases

Cardiovascular disease is the most common cause of death. Improving the quality of the diet, such as increasing the consumption of whole grains, vegetables, and fruits, has a beneficial effect on cardiovascular complications. The Qur'an is a heavenly book in which there are 11 words about fruits and their derivatives, which indicates the value of fruits from the Quran's point of view. In general, the holy book of Qur'an has highlighted 5 fruits including olives, figs, dates, pomegranates and grapes and has repeated them in various verses.

In this review study, noble verses of Qur'an, books on interpretation of Quran and reliable scientific databases such as Web of Science, PubMed, Scopus, IranMedex, Magiran, SID and Google Scholar were reviewed from 2000 to 2021. Related articles were reviewed using the keywords of Quran, olives, grapes, dates, figs, pomegranates, and cardiovascular disease.

The results suggest that the fruits mentioned in the Qur'an such as olives, figs, dates, grapes, and pomegranates, play a major role in human nutrition and health due to their strong antioxidant effects, which reduce oxidative stress, and substances such as carotenoids, anthocyanins, and phenolics. The results of the studies have shown the anti-inflammatory and antioxidant role of these fruits. It has been proven that these fruits have a high potential to prevent cardiovascular diseases, reduce the complications of cardiovascular diseases and improve the health of these patients.

The results of the studies have suggested that consumption of the fruits mentioned in the Qur'an reduces the risk of cardiovascular events, causes recovery in cardiovascular patients and reduces mortality due to cardiovascular diseases.
