            Introduction

            Quince is often incorporated into our daily lives as an extract, powder, or tea. It is often used as a compressor application for swollen and painful parts, injuries, and cuts. Its lotion is perfect for soothing eyes. This fruit is also available as juice, wine, jelly, jam, pudding, and other sweets.

            Guava is a tropical fruit cultivated mainly in Brazil, Venezuela, Colombia, and Mexico. The fruit, its juice, and leaves are often used as medicine. They are usually eaten raw, though they may be used in beverages, jams, and desserts.

            Vitamins and Minerals

            Guava has richer vitamin and mineral profiles than quince. It contains 15 times more vitamin A and vitamin C than quince, and it is also significantly richer in all B-group vitamins.

            Health Impact

            These fruits have been part of the human diet since ancient times, and their health benefits have been known for centuries.

            Quince is known for its effects on digestive disorders. Quince may decrease the risk of having stomach ulcers. Quince may beneficially affect nausea, constipation, and hemorrhoids, whereas quince leaves may help with diarrhea. It may also beneficially affect coughing and help heal cuts and injuries (1, 2, 3).

            Guava has beneficial effects on diabetes and hypercholesterolemia. It also acts as a cough suppressant. It has protective functions against heart disease and cancer development (4).

            Both these fruits are rich in antioxidants that neutralize free radicals and reduce oxidative stress, which lowers inflammation and decreases the risks of multiple diseases. The guava leaf extract is anti-hyperglycemic and widely used in treating diabetes (5).

            Cardiovascular health

            Section reviewed by cardiologist Astghik Grigoryan Article author photo Astghik Grigoryan

            Studies have shown that extracts from quince leaves at 320mg/kg doses have an antihypertensive effect similar to Captopril. Another study found that an aqueous-methanolic extract from quince seeds was most effective at 600mg/kg and prevented increased blood pressure (6).

            Guava also has ACE inhibitory activity similar to antihypertensive drugs like Captopril and Perindopril and antioxidative properties, essential in reducing cardiovascular risk (7, 8).

            The quince fruit is packed with quinic acid, shikimic derivatives, procyanidins, and flavonoids, which can help prevent atherosclerosis. Notably, the quince peel extract had the highest antioxidant activity (6).

            According to this research, the extract obtained from quince leaves can regulate the levels of lipids in the blood, much like Atorvastatin. However, it did not show significant improvement in atherosclerosis caused by a high-fat diet. Therefore, reducing the intake of high-fat foods in your diet is recommended. 

            Other studies also found that the aqueous extract of quince fruit and guava may significantly lower serum levels of TG (triglycerides) and LDL (“bad” cholesterol) while increasing the levels of HDL (“good” cholesterol) (6, 9).
