Bitter Melon (Momordica charantia), commonly referred to as bitter gourd, karela, and balsam pear, is widely used as a vegetable in Bangladesh and several other countries in Asia, the Amazon, East Africa, and the Caribbean. The food looks like a bumpy cucumber and has a pungent taste. Bitter melon also has a strong history of use in folk medicine.

Even though bitter melon calories are very low, keep in mind that the nutrition changes if you add other ingredients (such as oil) to prepare it.

There is very little fat in bitter melon. One entire bitter melon contains less than a single gram of fat.

Protein in Bitter Melon

Bitter melon is not a good source of protein. There is just over 1 gram of protein in a single bitter melon.

Micronutrients in Bitter Melon

Micronutrients in the vegetable again vary based on the part of the vegetable that you eat. If you consume the pods, you'll benefit from vitamins including vitamin A, vitamin C, and folate. Minerals in the pods include calcium, potassium, iron magnesium, sodium, zinc, and selenium.

If you consume the leafy tips, you'll consume the same micronutrients in slightly higher amounts.

Bitter melon is not a good source of any micronutrients except for vitamin C.

Health Benefits

Bitter melon juice, fruit, and dried powder are reported to possess antioxidant, anti-inflammatory, anti-cancer, anti-diabetic, anti-bacterial, anti-obesity, and other disease prevention properties.

Though research is ongoing, strong clinical evidence does not exist to support all of bitter melon's medicinal uses.

In Asia, South America, India, and East Africa, bitter melon is often used to treat diabetes. However, a published review concluded that high-quality studies with human subjects are limited and often too flawed to provide strong enough evidence. A 2014 study published in Nutrition and Diabetes showed that bitter melon did not provide any significant benefit to diabetic patients.

Another published review evaluated evidence regarding the use of bitter melon to treat high cholesterol, obesity, cardiac function, hypertension, and certain cancers. Again, authors also note that most bitter melon studies suffer from poor design and conclude that more high-quality research is needed to understand bitter melon benefits.
