Many people enjoy guava fresh, but it can be juiced or combined with many other foods. The following beneficial properties are posted on Health.com.
Guava leaves and fruit can help control blood sugar
Guava leaves have been used in traditional folk medicine for many years, but recent research has shed light on their role in blood sugar control. Animal studies have shown that guava leaf extract has a powerful effect on insulin sensitivity, improving fasting blood sugar and insulin resistance.
A 2016 study found that eating guava without its skin was effective in lowering blood sugar levels. The pectin or fiber in guava can slow down the absorption of glucose in the intestine and improve glucose tolerance.
Another study in 2025 found that guava leaves may help treat diabetes. While guava cannot replace a doctor’s prescription, it can be a lifestyle choice that can help support regular diabetes care.
May support heart health
According to folk experience, guava leaf extract appears to have antihypertensive properties, but its mechanism of action is not fully understood.
A 2022 animal study found that guava's effects on blood pressure may be related to the sympathetic nervous system. Scientists stressed that more human research is needed.
The flesh of the guava fruit may have a positive effect on blood lipid levels. Researchers noted significant reductions in triglycerides, total cholesterol, and LDL cholesterol after study participants were supplemented with guava for six weeks.
Since high cholesterol and triglycerides can be detrimental to heart health, including guava in your diet helps support a healthy immune system.
Vitamin C is an antioxidant that plays a role in the immune system. Since the body cannot produce vitamin C on its own, it must be supplemented through the diet. Guava is high in vitamin C.

Good for digestive health
Guava is a great source of fiber, making it an ideal choice for a healthy digestive system. A medium-sized guava contains about 3 grams of fiber. Including guava in your diet can help promote regular bowel movements and prevent constipation.
Several studies have shown the effectiveness of this fruit in reducing the symptoms of diarrhea. Guava fruit extract has been linked to positive effects on balanced gut health which can help support a healthy heart.
