100 grams of these beans have 2.7 mg of iron, which is about 15 percent of the daily recommended intake.

Tip – to increase the absorption of iron from plant sources (called non-heme iron), it is recommended to eat them with a good source of vitamin C, like – kiwi, citrus fruits, bell peppers, or strawberries.


Proteins are organic molecules that are made up of amino acids. The organs, muscles, and immune system are made up mostly of protein. Also, protein helps replace, maintain, and build the tissues in the physical body.

Other benefits of protein include:

  • boosting a stronger immune system;
  • providing energy;

There are two types of dietary fiber: insoluble and soluble.

Insoluble fiber accelerates the passage of waste and food. Insoluble fiber doesn’t absorb water or dissolve. It is found in foods such as wheat bran, whole-wheat flour, beans, nuts, and vegetables.

Soluble fiber absorbs water from food, which slows down digestion. This is helpful for supporting healthy cholesterol and blood sugar (glucose) levels. Soluble fiber is found in foods such as barley, oats, beans, peas, citrus fruits, and apples.

According to research, adding more foods high in dietary fiber can be an effective method to lose weight.

Also, a 2017 British study established that adding 7 grams of dietary fiber a day substantially increased heart health.

100 grams of petai beans have 3.4 grams of dietary fiber which is about 14 percent of the daily recommended intake.

100 grams of these beans have 0.5 mg of manganese which is about 22 percent of the daily recommended intake.


Calcium is essential for various body functions, like – muscle contraction, nerve impulse transmission, and blood clotting.

Calcium also helps to mediate enzymatic reactions and the secretion of hormones required for cell metabolism.
