Gac fruit, scientifically known as Momordica cochinchinensis, is a distinctive tropical fruit native to Southeast Asia, particularly Vietnam and Thailand. Often called the “fruit from heaven,” it has a unique appearance. This round or ovoid fruit is about the size of a small melon and is covered with numerous small spines, resembling a pufferfish. As it ripens, its skin transforms from green to a vibrant deep orange or red.
Gac Fruit’s Nutritional Profile
Gac fruit is recognized for its rich nutritional content, particularly within the red pulp surrounding its seeds, known as the aril. This aril is especially abundant in carotenoids, which are natural pigments. Among these, lycopene is present in exceptionally high concentrations, reported to be up to 70 times more than in tomatoes. Beta-carotene, a precursor to Vitamin A, is another prominent carotenoid found in Gac fruit, often in amounts significantly greater than in carrots.
Beyond carotenoids, Gac fruit also contains other beneficial compounds. It is a source of alpha-tocopherol (Vitamin E) and polyunsaturated fatty acids, including omega-3 and omega-6. The fruit also provides Vitamin C, flavonoids, and polyphenols. These components contribute to its nutritional value and potential health benefits.
Major Health Benefits of Gac Fruit
The impressive array of nutrients in Gac fruit translates into several notable health benefits. Its high concentration of beta-carotene makes it particularly supportive of eye health. Beta-carotene converts to Vitamin A in the body, which is essential for maintaining good vision, helping to prevent conditions such as age-related macular degeneration, cataracts, and night blindness. The presence of zeaxanthin further enhances eye protection by shielding tissues from harmful light and reducing oxidative damage.
Gac fruit’s rich antioxidant profile, particularly its lycopene and beta-carotene content, helps to neutralize harmful free radicals in the body. Its antioxidant activity helps reduce the risk of chronic diseases, including certain cancers, by preventing abnormal cell growth and protecting against cellular damage. These compounds also support cardiovascular health by lowering cholesterol and reducing inflammation, improving blood circulation.
Gac fruit’s nutrients also contribute to healthier skin. Beta-carotene, Vitamin C, and healthy fats work together to improve skin elasticity, reduce the appearance of wrinkles, and promote a natural glow. The antioxidants in Gac fruit also help protect skin cells from oxidative stress and environmental damage. Its Vitamin C content strengthens the immune system, aiding the body’s ability to fight infections and inflammation. Omega-3 fatty acids and alpha-tocopherol also provide anti-inflammatory properties, protecting the body from daily stresses.
How to Use Gac Fruit
Gac fruit can be incorporated into the diet in various ways, often leveraging its vibrant color and mild flavor. In its native Vietnam, a popular traditional dish is “Xoi Gac,” a sticky rice preparation where the red aril of the fruit is mixed with glutinous rice, imparting a striking red color and unique taste. This dish is frequently served during special occasions and festivals, such as Tet (Lunar New Year) and weddings. The fruit’s pulp can also be added to soups, smoothies, and other desserts.
Beyond fresh consumption, Gac fruit is available in processed forms. Its aril can be used to extract oil, which is rich in fat-soluble vitamins and carotenoids, aiding in nutrient absorption. Gac fruit extracts are also found in dietary supplements, juices, and pastes, offering year-round access to its beneficial compounds. Immature or green Gac fruits and young leaves are sometimes boiled and used in curries, particularly in Thailand.
Things to Consider Before Consumption
Gac fruit is seasonal, typically harvested between December and February in Southeast Asia. While fresh fruit is available in Asian supermarkets or online, its exotic nature can lead to higher prices. For extended storage, the pulp can be refrigerated, frozen, or processed into oil or powder.
The spiny outer skin and seeds are generally not consumed and may be toxic if ingested raw. The red aril and the cooked pulp are the primary edible portions. Gac fruit is generally safe, but introducing it gradually is advisable, as large quantities may cause digestive discomfort in some individuals. Individuals with allergies to similar fruits or those on specific diets should consult a health professional before incorporating Gac fruit.
