Top 10 Health Benefits of Jackfruit
Jackfruit (Artocarpus heterophyllus) is a giant fruit grown in tropical and subtropical regions, primarily in South Asia (e.g. India, Bangladesh, Sri Lanka) and Southeast Asia (e.g. Indonesia, Thailand, Philippines, Malaysia). It is a member of Moraceae family, which also includes breadfruit, fig, and mulberry.
Jackfruit is considered the largest tree-borne fruit in the world with an average weight of 3.5-10 kg and can reach up to 45 kg in weight, 90 cm in length, and 50 cm in diameter.
As in the durian fruit, the outer surface of the jackfruit is covered by thorns and is green in color, but the difference is that the durian thorns are pointed and sharp while the thorns of jackfruit are smaller and blunt. Both have distinct, strong aromas that are different and may be repelling to foreigners who are unfamiliar with the smell.
The inside of the fruit contains hundreds of yellow-colored bulbs and each bulb consists of sweet flesh (sheath) that encloses a smooth, oval, light-brown seed. The seeds can also be eaten and are loaded with various nutrients.

Is Jackfruit Seed Edible? If So, How Can I Eat It?
Yes, the jackfruit seeds are edible and highly nutritious. They contain good amounts of vitamins and minerals, including protein, riboflavin, thiamine, magnesium, and phosphorus.
Jackfruit seeds are also packed with fiber and resistant starch, both of which act as food for your beneficial gut bacteria.
Though jackfruit seeds contain several nutrients, some health experts believe that jackfruit seeds can be harmful to the body if eaten raw.
Raw jackfruit seeds contain antinutrients such as tannins and trypsin inhibitors. These compounds are known to interfere with nutrient absorption and digestion, making it difficult to digest food. For these reasons, you should not eat raw jackfruit seeds.
The good news is that heat inactivates these antinutrients. Therefore, always cook them before you eat them.
Jackfruit seeds can be prepared in many ways. However, roasting or boiling are two of the most popular preparation methods.
You can roast jackfruit seeds by preheating the oven to 205°C and laying them flat on a pan. Bake the seeds for 20 minutes, or until they are brown and toasted.
You can also boil jackfruit seeds in a large pot of water for 20–30 minutes. Once the seeds are tender, drain the pot and let them cool and dry.
