Guava fruits are amazingly rich in antioxidants, vitamin C, potassium, and fiber. This remarkable nutrient content gives them many health benefits. Here are 8 evidence-based health benefits of guava fruits and leaves.
May Help Lower Blood Sugar Levels– Some evidence suggests that guava can improve blood sugar control. Several test-tube and animal studies found that guava leaf extract improved blood sugar levels, long-term blood sugar control, and insulin resistance. This is good news for people with diabetes or those at risk.
May Boost Heart Health– Guavas may help boost heart health in a number of ways. Many scientists believe that the high levels of antioxidants and vitamins in guava leaves may help protect your heart from damage by free radicals. The higher levels of potassium and soluble fiber in guavas are also thought to contribute to improved heart health.
Additionally, guava leaf extract has been linked to lower blood pressure, a decrease in “bad” LDL cholesterol, and a rise in “good” HDL cholesterol. Since high blood pressure and high levels of LDL cholesterol are linked to higher risks of heart disease and stroke, taking guava leaf extract could lead to valuable benefits. What’s more, the fruit may have benefits for heart health as well.
May Help Relieve Painful Symptoms of Menstruation-Many women experience dysmenorrhea — painful symptoms of menstruation, such as stomach cramps. However, there is some evidence that guava leaf extract may reduce the pain intensity of menstrual cramps. A study in 197 women who experienced painful symptoms found that taking 6 mg of guava leaf extract daily resulted in reduced pain intensity. It appeared to be even more powerful than some painkillers.
May Benefit Your Digestive System- Guavas are an excellent source of dietary fiber. Therefore, eating more guavas may aid healthy bowel movements and prevent constipation. Just one guava can provide 12% of your recommended daily intake of fiber. Additionally, guava leaf extract may benefit digestive health.
Studies suggest that it may reduce the intensity and duration of diarrhea. Several studies have also shown that guava leaf extract is antimicrobial. This means that it can neutralize harmful microbes in your gut that can cause diarrhea. Guava leaf extract is also thought to help relieve uterine cramps.
May Aid Weight Loss- Guavas are a weight-loss-friendly food. With only 37 calories in one fruit and 12% of your recommended daily fiber intake, they are a filling, low-calorie snack. Unlike some other low-calorie snacks, they are packed with vitamins and minerals — so you aren’t losing out on important nutrients.
May Have an Anticancer Effect– Guava leaf extract has been shown to have an anticancer effect. Test-tube and animal studies show that guava extract can prevent and even stop the growth of cancer cells. This is likely due to the high levels of powerful antioxidants that prevent free radicals from damaging cells, one of the main causes of cancer.
One test-tube study found that guava leaf oil was four times more effective at stopping cancer cell growth than certain cancer drugs. Although the results of test-tube experiments are promising, it doesn’t mean that guava leaf extract helps treat cancer in people. Further studies are needed before any claims can be made.
May Help Boost Your Immunity-Low levels of vitamin C are linked to an increased risk of infections and illness. Guavas are a fantastic way to get this nutrient, as they’re one of the richest food sources of vitamin C. In fact, one guava provides about double the Reference Daily Intake (RDI) for vitamin C. This is almost twice the amount you would get from eating an orange.
Vitamin C plays an important role in maintaining a healthy immune system. Although it’s not proven to prevent the common cold, vitamin C has been shown to reduce a cold’s duration. It’s also linked to antimicrobial benefits. This means that it helps kill off bad bacteria and viruses that can lead to infections. Because vitamin C can easily be flushed out of your body, it’s important to regularly get enough through your diet.
Eating Guavas May Be Good for Your Skin-The wide range of vitamins and antioxidants packed into a guava may work wonders for your skin. Its antioxidants may protect your skin from damage, which can slow down its aging process, helping prevent wrinkles. What’s more, guava leaf extract may even help treat acne when applied directly to your skin.
One test-tube study found that guava leaf extract was effective at killing acne-causing bacteria — likely due to its antimicrobial and anti-inflammatory properties. More studies are needed to confirm the role of guavas and guava extract in maintaining healthy skin. (Healthline.com)
