Is Guava Good for Diabetes? Let’s Find Out


Guava is a delicious and nutritious fruit found all year round in most warm and temperate states. They are tasty and have a low Glycemic Index (GI), which measures how quickly carbohydrates are broken down and released as glucose into the system.

It means guavas can be particularly helpful in maintaining healthy blood sugar levels. In addition, guavas are indigenous to Mexico, Central America, and northern South America and can mature at any time of the year.

As a diabetic patient, following a strict diet is essential to keep your blood glucose or blood sugar levels within safe ranges. Blood glucose is your primary energy source, which you get from the food you consume. 

Many foods can help regulate your blood sugar levels. The rise in blood glucose signals the release of insulin into your bloodstream. High insulin levels can lead to the storage of extra sugar as fat, increasing blood pressure, bad cholesterol, triglyceride levels, and appetite.

Nutritional Value of Guava

Guavas contain essential nutrients, including calcium, manganese, lycopene, potassium, and vitamins A and C.

With its low glycemic index of 12–24, the fruit is ideal for those who don’t want to experience a blood sugar spike. Moreover, guavas are a valuable source of iron, vitamin B6, calcium, magnesium, vitamin D, and vitamin A. They are also rich in antioxidants, which offer numerous health benefits.

As per USDA, one hundred grams of guava offer the following nutrients.

Glycemic Index of Guava

The glycemic index (GI) measures how a food item can raise blood sugar levels. Foods with a high GI are quickly absorbed by the body, causing a rapid increase in blood sugar. Conversely, foods with a low GI are absorbed more slowly and can help maintain stable blood sugar levels.

The higher the GI, the quicker the rise in blood sugar. You can identify how quickly a fruit will convert to glucose in your body by looking up its glycemic index (GI).

Guava is an excellent option for those with diabetes or anyone looking to maintain stable blood sugar levels. That is because it has a low glycemic index (GI) score of 12-24.

Furthermore, only 8.92 g of sugar is present per 100 grams of guava, making it easier to digest and absorb. As a result, it leads to minimal spikes in blood glucose levels. 

It’s essential to remember that the glycemic index is only one factor to consider when managing blood sugar levels. One should also take a meal’s portion size and overall nutrient balance.

Guava for Diabetes – The Connection

There is no evidence to suggest that guava directly affects diabetes. However, it is a nutritious fruit that can be part of a healthy diet. Guava is rich in vitamin C, fibre, and other essential nutrients.

Can diabetic patient eat guava?

There is no indication that guava consumption is unsafe for people with diabetes.

It is crucial, however, that they manage their carbohydrate intake, including that from fruit, as part of their blood sugar control plan.

Guava has a moderate to low glycemic index (GI), which means that it is absorbed more slowly and thus less likely to cause a spike in blood sugar levels.

Benefits of Guava for People with Diabetes

Guava is Rich in Fibre

Research indicates that guavas are an excellent choice for people with diabetes looking to regulate their blood sugar levels, as they are high in fibre.

This fibre takes longer to digest and helps slow down sugar’s release into the bloodstream. As a result, people with diabetes can avoid periods of hypoglycemia as the fruit is digested gradually over time.

Guava can Improve Digestion.

Guavas are an excellent choice for those trying to burn fat, as they are a delicious, low-calorie snack high in nutrients.

Not only that, but they contain a good amount of protein and fibre, which both take longer to digest and can help keep you feeling full for longer. Furthermore, the high fibre content helps to regulate metabolism. Lastly, unripe guavas have much less sugar than most other fruits.

Research has shown that consuming guavas is beneficial for maintaining healthy antibacterial gut flora. Moreover, eating any type of fruit can help improve digestion and promote regular bowel movements, contributing to weight loss.

Weight Management

Due to its low-calorie content, guava can help in weight management, an essential factor for people with diabetes. Excessive weight can lead to cardiovascular issues in people with diabetes. Additionally, the fibre in guava can aid in weight loss.

Rich Source of Vitamin C

Guavas are an excellent source of Vitamin C. Contrary to popular belief, guavas contain more vitamin C than citrus fruits such as oranges

Studies have shown that inadequate levels of vitamin C can put individuals at a heightened risk of diseases and infections. Furthermore, guava has antibacterial properties, helping eliminate dangerous bacteria and viruses that could lead to illnesses. 

It is important to regularly consume adequate amounts of vitamin C as its depletion is a common phenomenon.

In addition, guavas promote a robust immune system and manage chronic conditions like diabetes. Thus, guava is often considered a necessary fruit for regulating diabetes.

Low in sodium and High in Potassium

People with diabetes should pay close attention to their sodium intake, as too much salt can harm their health.

Guavas are a great option, as they contain a high level of potassium and low sodium, two essential nutrients needed to manage diabetes. Therefore, including guava in your diet can benefit your health and help maintain the balance of nutrients.

Cell Repair

Guavas contain phytonutrients such as carotenoids, polyphenols, and vitamin C, which function as natural antioxidants in the body.

Antioxidants help prevent or delay oxidative damage caused by free radicals, which our bodies produce. In addition, they also prevent oxidative stress due to toxins from our environment. Research has indicated that this damage can lead to inflammation and illness.
