Bitter melon

What does bitter melon look like?  Despite the fact that it comes in a relatively wide range of varieties, bitter melon is easily recognisable due to its close resemblance to the common cucumber: elongated, with green ridged or bumpy skin and large seeds. The popular Indian bitter melon, the same variety used in Okinawan and Japanese cuisine, is generally 10-20 cm long, has a thick, dark green skin, full of wart-like bumps and pointy ridges. It has an elongated, cucumber shape, with pointy ends. The flesh is whiteish and contains large, irregular-shaped reddish-brownish seeds.

The Chinese bitter melon has a lighter green skin, softer bumps or ridges and ranges from 10-15 cm to 20-30 cm in length. This variety is fuller in width and looks more like a zucchini than a cucumber. Bitter melons are traditionally consumed while still green, but they are edible even when their skin starts turning yellow or brown. Color indicates a different ripening level.

What does bitter melon taste like? Its name gives away its taste: bitter. While there may be slight variations between cultivars, bitter melons have a decidedly bitter taste, which is why they are an aquired taste for first-timers. Bitter melon has a crisp, cucumber-like texture. Green ones are quite tender and require little to no cooking, especially if sliced finely, while yellow or brownish bitter melons have a chewier texture. Despite being a fruit, bitter melon is used as a culinary vegetable. The fact that it looks a lot like a bumpy, ridged cucumber adds to the confusion.

The fruit is beginning to enjoy an increase in popularity as a result of studies asserting its beneficial effects on human health, most notably disease management and nutrition. Here are the 7 most noteworthy health benefits and nutrition facts of bitter melon:

1) Aids digestion. Rich in dietary fiber (2.8 g/100 g of fruit), bitter melon is a good natural laxative which stimulates peristalsis, a series of movements of the gastrointestinal muscles that help move food down the digestive tract. Regular consumption of bitter melon thus contributes to relieving constipation and, at the same time, supports healthy gut bacteria which favors digestion and nutrient absorption.

2) Battles infection. Traditional medical practices recommend the topical application of bitter melon for the treatment of skin problems such as psoriasis, as well as open wounds and skin infections. Although research on the matter is labeled as insufficient, it is believed that bitter melon can successfully battle skin infections due to its ability to cleanse the blood from toxins.

3) Great tonic. Bitter melon is a great source of essential nutrients, most notably vitamin C, folate, vitamin K, potassium, magnesium, phosphorus and zinc. Regular consumption of the fruit helps boost immunity, reduce infection rates and severity, improve blood pressure, muscle activity and maintain strong, healthy bones. And with only 17 kcal/100 g of fruit, bitter melon is an ideal choice for maintaining a slim waistline.

4) Good for bright skin and healthy eyes. Bitter melon is one of the few fruits that naturally purify the blood of toxins, giving the skin a healthy glow. In addition to brightening the skin, the fruit contains powerful provitamin A antioxidants (beta-carotene, alpha-carotene, lutein, zeaxanthin) which maintain retina health, protect against harmful free radicals from blue light especially and improve eyesight quality.

5) Boosts immunity. According to the National Nutrient Database for Standard Reference, 100 g of bitter melon contains 84 mg of vitamin C. Vitamin C not only supports the immune function, but also reduces the incidence, severity and duration of viral and bacterial infections, notably respiratory infections and maintains overall low inflammation markers, contributing to a lower risk of developing chronic illnesses (cancer, diabetes, heart disease, dementia, etc).

6) Exhibits anticancer properties. An in vitro study conducted by Dr. Ratna Ray and colleagues at the Saint Louis University and the University of Hawaii (‘Bitter Melon (Momordica charantia) Extract Inhibits Breast Cancer Cell Proliferation by Modulating Cell Cycle Regulatory Genes and Promotes Apoptosis’, published in the February 23, 2010 issue of Cancer Research) showed that cultured breast cancer cells underwent apoptosis (programmed cell death) when exposed to liquid bitter melon extract. Although preliminary, these results encourage the consumption of bitter melon and bitter melon extracts as a means for breast cancer prevention.

7) Lowers blood sugar levels and contributes to better diabetes management. Vicine, charantin and polypeptide-P are the three naturally occurring compounds that are responsible for the hypoglycemic and anti-diabetic properties of bitter melon. According to clinical studies, these compounds help improve insulin sensitivity, glycogen synthesis in the liver, reduce insulin resistance and overall blood glucose levels, sparking hope for the emergence of an alternative therapy for diabetes management and treatment.

Nevertheless, pregnant women are advised to avoid eating bitter melon because it increases the risk for miscarriages as a result of inducing contractions. Nursing mothers should also avoid bitter melon due to it containing several compounds that may prove harmful for babies. The reddish arils surrounding the seeds are also potentially toxic for young children.

Other than this, bitter melon is safe for human consumption. Only mild side effects such as gastrointestinal discomfort or diarrhea are reported in particularly sensitive people who consume large amounts of the fruit.

Overall, preliminary research shows bitter melon is an amazingly healthy food, rich in essential nutrients and vital antioxidant compounds believed to offer significant anticancer and anti-diabetic protection, as well as stimulate immunity, reduce inflammation and improve digestive health. But there are many more secrets to this vegetable look-alike that Chinese and Okinawan centenarians love. Don’t let its bitter, unappealing taste fool you into thinking less of it.
