6 Benefits of Bitter Melon (Bitter Gourd) and Its Extract
Bitter melon — also
known as bitter gourd or Momordica charantia — is a tropical vine that belongs
to the gourd family and is closely related to zucchini, squash, pumpkin, and
cucumber. It’s cultivated around the world for its edible fruit, which is
considered a staple in many types of Asian cuisine. The Chinese variety is
typically long, pale green, and covered with wart-like bumps. On the other
hand, the Indian variety is more narrow and has pointed ends with rough, jagged
spikes on the rind. In addition to its sharp flavor and distinct appearance,
bitter melon has been associated with several impressive health benefits. Here
are 6 benefits of bitter melon and its extract.
1. Packs Several Important Nutrients
Bitter melon is a great
source of several key nutrients. One cup (94 grams) of raw bitter melon provides.
- Calories: 20
- Carbs: 4 grams
- Fiber: 2 grams
- Folate: 17% of the RDI
- Iron: 4% of the RDI
- Potassium: 8% of the RDI
- Vitamin A: 44% of the RDI
- Vitamin C: 93% of the Reference Daily Intake (RDI)
- Zinc: 5% of the RDI
Bitter melon is
especially rich in vitamin C, an important micronutrient involved in disease
prevention, bone formation, and wound healing.
It’s also high in
vitamin A, a fat-soluble vitamin that promotes skin health and proper vision. It
provides folate, which is essential for growth and development, as well as
smaller amounts of potassium, zinc, and iron. Bitter melon is a good source of
catechin, gallic acid, epicatechin, and chlorogenic acid, too — powerful
antioxidant compounds that can help protect your cells against damage. Plus,
it’s low in calories yet high in fiber — fulfilling approximately 8% of your
daily fiber needs in a single one-cup (94-gram) serving.
SUMMARY
Bitter melon is a good
source of nutrients like fiber, vitamin C, folate and vitamin A.
2. Can Help Reduce Blood Sugar
Thanks to its potent
medicinal properties, bitter melon has long been used by indigenous populations
around the world to help treat diabetes-related conditions. In recent years,
several studies confirmed the fruit’s role in blood sugar control.A 3-month
study in 24 adults with diabetes showed that taking 2,000 mg of bitter melon
daily decreased blood sugar and hemoglobin A1c, a test used to measure blood
sugar control over three months. Another study in 40 people with diabetes found
that taking 2,000 mg per day of bitter melon for 4 weeks led to a modest
reduction in blood sugar levels. What’s more, the supplement significantly
decreased levels of fructosamine, another marker of long-term blood sugar
control. Bitter melon is thought to improve the way that sugar is used in your
tissues and promote the secretion of insulin, the hormone responsible for
regulating blood sugar levels. However, research in humans is limited, and
larger, more high-quality studies are needed to understand how bitter melon may
impact blood sugar levels in the general population.
SUMMARY
Bitter melon has been
shown to improve several markers of long-term blood sugar control, including
levels of fructosamine and hemoglobin A1c. Still, more high-quality research is
needed.
3. May Have Cancer-Fighting Properties
Research suggests that
bitter melon contains certain compounds with cancer-fighting properties. For
example, one test-tube study showed that bitter melon extract was effective at
killing cancer cells of the stomach, colon, lung, and nasopharynx — the area
located behind the nose at the back of your throat. Another test-tube study had
similar findings, reporting that bitter melon extract was able to block the
growth and spread of breast cancer cells while also promoting cancer cell death.
Keep in mind that these studies were performed using concentrated amounts of
bitter melon extract on individual cells in a laboratory.
Further research is
needed to determine how bitter melon may affect cancer growth and development
in humans when consumed in the normal amounts found in food.
SUMMARY
Test-tube studies show
that bitter melon may have cancer-fighting properties and could be effective
against stomach, colon, lung, nasopharynx, and breast cancer cells.
4. Could Decrease Cholesterol Levels
High levels of
cholesterol can cause fatty plaque to build up in your arteries, forcing your
heart to work harder to pump blood and increasing your risk of heart disease. Several
animal studies found that bitter melon may decrease cholesterol levels to
support overall heart health. One study in rats on a high-cholesterol diet
observed that administering bitter melon extract led to significant decreases
in levels of total cholesterol, “bad” LDL cholesterol, and triglycerides. Another
study noted that giving rats a bitter melon extract significantly reduced
cholesterol levels compared to a placebo. Higher doses of bitter melon showed
the greatest decrease. Still, current research on the potential
cholesterol-lowering properties of bitter melon is mostly limited to animal
studies using large doses of bitter melon extract.
Additional studies are
needed to determine whether these same effects apply to humans eating the gourd
as part of a balanced diet.
SUMMARY
Animal studies show that
bitter melon extract may decrease cholesterol levels, which could help support
heart health. Nonetheless, human research to confirm these effects is lacking.
5. May Aid Weight Loss
Bitter melon makes an
excellent addition to a weight loss diet, as it’s low in calories yet high in
fiber. It contains approximately 2 grams of fiber in each one-cup (94-gram)
servin. Fiber passes through your digestive tract very slowly, helping keep you
fuller for longer and reducing hunger and appetite. Therefore, swapping
higher-calorie ingredients with bitter melon could help increase your fiber
intake and cut calories to promote weight loss. Some research also shows that
bitter melon can have beneficial effects on fat burning and weight loss.
One study found that
consuming a capsule containing 4.8 grams of bitter melon extract each day led
to significant decreases in belly fat. Participants lost an average of 0.5
inches (1.3 cm) from their waist circumference after seven weeks. Similarly, a
study in rats on a high-fat diet observed that bitter melon extract helped
decrease body weight compared to a placebo. Note that these studies were
performed using high-dose bitter melon supplements. It remains unclear whether
eating bitter melon as part of your regular diet would have the same beneficial
effects on health.
SUMMARY
Bitter melon is low in
calories but high in fiber. Human and animal studies have found that bitter
melon extract may also help decrease belly fat and body weight.
6. Versatile and Delicious
Bitter melon has a sharp
flavor that works well in many dishes. To prepare it, start by washing the
fruit and cutting it lengthwise. Then use a utensil to scoop out the seeds from
the center, and cut the fruit into thin slices. Bitter melon can be enjoyed raw
or cooked in various recipes. In fact, it can be pan-fried, steamed, baked, or
even hollowed out and stuffed with your choice of fillings. Here are a few
interesting ways to add bitter melon to your diet:
- Juice bitter melon along with a few other fruits and vegetables for a nutrient-packed beverage.
- Mix bitter melon into your next stir-fry to bump up the health benefits.
- Sauté bitter melon alongside tomatoes, garlic, and onions and add to scrambled eggs.
- Combine seedless bitter melon with your choice of dressing and garnish for a savory salad.
- Stuff with ground meat and vegetables and serve with a black bean sauce.
SUMMARY
Bitter melon is easy to
prepare and can be used in many different dishes and recipes.
Potential Side Effects
When enjoyed in
moderation, bitter melon can be a healthy and nutritious addition to your diet.
However, consuming high amounts of bitter melon or taking bitter melon supplements
may be associated with several adverse effects. In particular, bitter melon has
been linked to diarrhea, vomiting, and stomach pain. It’s also not recommended
for women who are pregnant, as its long-term effects on health have not been
extensively studied. Due to its impact on blood sugar, you should consult with
your healthcare provider before eating it if you’re taking any blood
sugar-lowering medications. Also, talk with a healthcare professional before
supplementing with bitter melon if you have any underlying health conditions or
are taking any medications, and be sure to use as directed.
SUMMARY
Bitter melon may be
associated with adverse side effects. Pregnant women, people with underlying
health problems, and those taking blood sugar-lowering medications should
consult their doctor before use.
Conclusion
Bitter melon is a fruit
in the gourd family with a unique appearance and flavor. It’s not only rich in
several important nutrients but also linked to numerous health benefits,
including improved blood sugar control and cholesterol levels. Note that people
who are pregnant or on certain medications — particularly blood sugar-lowering
medications — should speak to their healthcare provider before consuming high
amounts or taking supplements. Still, in moderation, bitter melon makes for a
flavorful, nutritious, and easy addition to a healthy, well-rounded diet.
