As you can see, guava is a low-calorie fruit that is high in fiber and vitamin C. It also contains significant amounts of other essential vitamins and minerals.
1. Boosts Immunity
Guava is one of the best sources of vitamin C, which is essential for a healthy immune system. A 100-gram serving of guava provides 228% of the recommended daily intake of vitamin C. Vitamin C is an antioxidant that helps protect your cells from damage caused by free radicals.
A study published in the Journal of Agricultural and Food Chemistry found that guava extract can help boost the production of immune cells called lymphocytes and enhance their activity. This can help improve your body's ability to fight off infections and diseases.
2. Improves Digestion
Guava is rich in dietary fiber, which is essential for good digestion. A 100-gram serving of guava provides 5.4 grams of fiber, which is about 22% of the recommended daily intake.
Fiber helps promote regular bowel movements, prevent constipation, and keep your digestive system healthy. It also helps regulate blood sugar levels and can help reduce the risk of developing type 2 diabetes.
3. Reduces the Risk of Cancer
Guava contains antioxidants that can help protect your cells from damage caused by free radicals, which can lead to cancer. A study published in the Journal of Medicinal Food found that guava extract can help inhibit the growth of cancer cells in the prostate.
Another study published in the Journal of Agricultural and Food Chemistry found that guava extract can help induce apoptosis, or programmed cell death, in breast cancer cells. This suggests that guava may have potential as a natural treatment for breast cancer.
4. Lowers Blood Sugar Levels
Guava is low in glycemic index, which means it can help regulate blood sugar levels. A study published in the Journal of Ethnopharmacology found that guava leaf extract can help lower blood sugar levels in people with type 2 diabetes.
Another study published in the Journal of Medicinal Food found that guava leaf extract can help improve insulin resistance, which is a key factor in the development of type 2 diabetes.
5. Protects the Heart
Guava is rich in potassium, which is essential for a healthy heart. A 100-gram serving of guava provides 8% of the recommended daily intake of potassium.
Potassium helps regulate blood pressure, which can help reduce the risk of developing heart disease. A study published in the Journal of Agricultural and Food Chemistry found that guava extract can help reduce blood pressure in people with hypertension.
6. Improves Skin Health
Guava is rich in vitamin C, which is essential for the synthesis of collagen, a protein that helps keep your skin healthy and firm. Vitamin C also has antioxidant properties that can help protect your skin from damage caused by free radicals.
A study published in the Journal of Drugs in Dermatology found that a cream containing guava extract can help improve skin elasticity and reduce the appearance of wrinkles.
7. Enhances Brain Function
Guava is rich in vitamins and minerals that are essential for brain function, including vitamin C, vitamin B6, and magnesium. A study published in the Journal of Alzheimer's Disease found that magnesium can help improve cognitive function in older adults.
Another study published in the Journal of Nutrition, Health and Aging found that vitamin B6 can help improve memory and cognitive function in older adults.
8. Promotes Weight Loss
Guava is a low-calorie fruit that is high in fiber, which can help promote weight loss. A study published in the European Journal of Nutrition found that consuming high-fiber foods like guava can help reduce appetite and promote feelings of fullness.
Another study published in the Journal of Medicinal Food found that guava leaf extract can help inhibit the absorptionof carbohydrates, which can help reduce calorie intake and promote weight loss.
9. Strengthens Bones
