Varieties

There are different types of passion fruits; for example, the most common one is the purple passion fruit. The shell of the passion fruit is purple, and the inside is dark yellow. Another type is the yellow passion fruit which is sweeter than the purple passion fruit.

Mexican cream guava and lemon guava are suitable for desserts and frosting. There is also a very peculiar guava which is called strawberry guava due to its peculiar strawberry flavor. Other types also exist; however, these are the most commonly found in markets.

Cardiovascular health

Section reviewed by cardiologist Astghik Grigoryan

Cardiovascular disease (CVD) is a significant health concern, and diet plays a crucial role in its prevention and management. Both passion fruit and guava offer various nutrients and compounds that can contribute to heart health.

Passion fruit is rich in antioxidants, including vitamin C, beta-carotene, and flavonoids, which can help reduce inflammation and oxidative stress in the body. These compounds may contribute to lower blood pressure and improved heart health overall. Additionally, passion fruit contains fiber, which can help lower cholesterol levels, reducing cardiovascular risk (the risk of myocardial infarction, stroke, and death from cardiovascular disease) (1).

Guava is also packed with nutrients that are beneficial for cardiovascular health. It's particularly high in vitamin C, potassium, and fiber. Potassium helps regulate blood pressure, while fiber aids in lowering cholesterol levels. Guava also contains lycopene, another powerful antioxidant that may help reduce the risk of heart disease by preventing the oxidation of LDL (“bad” cholesterol) (2, 3).

In summary, both passion fruit and guava can be beneficial for cardiovascular health due to their high content of antioxidants, fiber, and other heart-healthy nutrients. Including a variety of fruits like passion fruit and guava in your diet, along with other heart-healthy foods, can contribute to overall cardiovascular wellness.

Diabetes

Guava consumption is linked to lower fasting blood glucose levels. As a result of having control over blood glucose and insulin, the risk of acquiring type 2 diabetes is reduced (4).

Consuming the rind of the passion fruit peel has beneficial effects on diabetic patients. The peel of yellow passion fruit consumption is linked with decreased risks of developing insulin resistance in type 2 diabetic individuals (5).

Obesity

Guava intake can lessen blood glucose and cholesterol levels, lowering the risk of developing high BMI levels and obesity (6).

Passion fruit consumption is related to decreased risk of obesity, which will be discussed further in the metabolic syndrome section.

Metabolic syndrome

Passion fruit contains piceatannol, which has overall reduced risks of insulin sensitivity, glucose and lipid level decrease, and overall protective effects. Piceatannol is linked with decreased risks of metabolic syndrome and obesity, as was mentioned before (7).

Guava and mostly guava leaves are important in reducing metabolic syndrome risks in individuals. As mentioned above, guava reduces risks of cardiovascular disorders, including hypertension, decreases risks of diabetes and obesity, and overall decreases risks of developing metabolic syndrome. In addition to that, guava leaf extract has a direct relation with decreased risks of metabolic syndrome (8).

Drug interactions

Passion fruit flowers might interact with central nervous system depressants and sedatives and amplify their effect and oversedate (9).

No drug interactions have been observed with guava.

Immunity

Vitamin C is an antioxidant and immune booster that helps prevent oxidative stress disorders due to its antioxidative effects. In addition to that, it boosts the immune system to fight off any infections (10).

Women’s Health

Guava extracts have reduced pain levels in women who have stomach cramps throughout their menstrual periods. These, however, occur during the intake of guava extracts rather than the guava fruit itself (11).

Kidney and liver

Patients with uncontrolled diabetes may develop nephropathy. Guava extracts have been proven to lower the risk of diabetic nephropathy (12).

The passion fruit extract has been shown to have hepatoprotective and nephroprotective properties (13).

Sleep

Passion fruit flower has a sedative and calming effect that acts on the central nervous system by flavonoids (14).
