Breadfruit, a tropical fruit with a starchy texture, has gained attention for its nutritional profile and potential health benefits. As more people seek alternatives to traditional staples, understanding the glycemic impact of foods becomes crucial.
The glycemic index of breadfruit is 65, placing it in the medium GI category. This means it causes a moderate rise in blood sugar levels compared to pure glucose. With a glycemic load of 17.6, breadfruit offers a balanced option for those monitoring their carbohydrate intake.
Beyond its glycemic properties, breadfruit packs a nutritional punch. A 100-gram serving contains 103 calories and provides significant amounts of potassium and vitamin C. Its low-fat, gluten-free nature makes it an appealing choice for various dietary needs. As research continues, breadfruit’s versatility and nutritional value may position it as a valuable addition to diets worldwide.
Understanding Glycemic Index
The glycemic index (GI) is a valuable tool for measuring how quickly carbohydrates affect blood sugar levels. It provides insights into food choices for managing diabetes and overall health.
Glycemic Index Explained
The glycemic index ranks carbohydrate-containing foods on a scale of 0 to 100 based on how rapidly they raise blood glucose levels. Foods with a high GI (70 or above) cause a quick spike in blood sugar, while those with a low GI (55 or below) lead to a more gradual increase.
Pure glucose serves as the reference point with a GI of 100. Foods are classified into three categories:
- Low GI: 0-55
- Medium GI: 56-69
- High GI: 70-100
Factors affecting a food’s GI include fiber content, processing methods, and cooking time.
Impact on Blood Sugar Regulation
The glycemic index helps predict how different foods will affect blood sugar levels. High-GI foods cause rapid increases in blood glucose, prompting the body to release more insulin to manage the spike.
Low-GI foods, in contrast, result in a slower and more steady rise in blood sugar. This gradual increase helps maintain more stable glucose levels over time.
Choosing low-GI foods can lead to improved blood sugar control and reduced insulin demand. This is particularly beneficial for individuals with diabetes or those at risk of developing the condition.
Significance for Diabetes Management
For people with diabetes, understanding the glycemic index is crucial for blood sugar management. Incorporating more low-GI foods into meals can help:
- Reduce blood glucose fluctuations
- Improve insulin sensitivity
- Decrease the risk of diabetes-related complications
A glycemic index chart serves as a useful reference for making informed food choices. It allows individuals to select foods that align with their blood sugar management goals.
Combining low-GI foods with protein and healthy fats can further slow digestion and minimize blood sugar spikes. This approach supports better overall glycemic control and long-term health outcomes for those with diabetes.

This comparison highlights breadfruit’s potential as a healthier alternative to high-GI staples. Its moderate GI and GL make it a suitable option for individuals managing their blood sugar levels, including those with diabetes.
Breadfruit’s nutritional profile further enhances its appeal. It is rich in potassium (490mg per 100g) and vitamin C (29mg per 100g), while being low in fat and cholesterol-free. These characteristics, combined with its moderate glycemic impact, contribute to breadfruit’s versatility as a nutritious food choice.
Potential Adverse Effects and Considerations
Breadfruit is generally safe for consumption, but there are some important factors to consider regarding allergies and proper storage. These aspects can impact the safety and quality of breadfruit for certain individuals.
Allergic Reactions
Some people may experience allergic reactions to breadfruit. Those with latex allergies should be particularly cautious, as breadfruit belongs to the same plant family as latex-producing trees. Symptoms of an allergic reaction can include itching, swelling, or difficulty breathing.
Cross-reactivity with other fruits in the Moraceae family, such as jackfruit or figs, is possible. Individuals with known allergies to these fruits should consult a healthcare provider before consuming breadfruit.
In rare cases, severe allergic reactions may occur. Seek immediate medical attention if symptoms like throat tightness or severe swelling develop after eating breadfruit.
Storage and Food Safety
Proper storage is crucial for maintaining breadfruit’s quality and safety. Fresh breadfruit should be stored in a cool, dry place and consumed within a few days of harvesting or purchase.
Cooked breadfruit can be refrigerated for 2-3 days. For longer storage, it can be frozen for up to 3 months. Ensure proper packaging to prevent freezer burn.
Discard breadfruit if it shows signs of mold, unusual discoloration, or off-odors. These may indicate spoilage and potential food safety risks.
When preparing breadfruit, wash it thoroughly to remove any surface contaminants. Use clean utensils and cutting surfaces to prevent cross-contamination.
