Gac fruit, also known as spiny bitter gourd, is a species of herbaceous plant of the cucurbitaceae / gourd family, produced in Taiwan, Southeast Asia and other regions. The fruit is in oval shape with rind in orange-red and covered with small soft spines. Its flesh is orange-yellow, and the fruit is wrapped with brown kernels. It is rich in nutrients that have anti-cancer, anti-oxidants, cholesterol-lowering and other effects, so it is also known as "paradise fruit", a fruit from heaven.
Although gac fruit has a little bitter taste, it is very beneficial to the body, especially the eyes. It contains more β-carotene, lycopene and vitamin A than ordinary fruits and vegetables that are easily absorbed by the body. β-carotene is very helpful in preventing vision impairment, dry eye syndrome, night blindness, etc., and can improve the condition of eye diseases such as macular degeneration. It also has good antioxidant capacity and can inhibit the incidence of certain cancers and heart diseases. Lycopene also has antioxidant effects, and can scavenge free radicals, delay aging, enhance immunity, inhibit cholesterol synthesis, reduce blood cholesterol concentration, and prevent arteriosclerosis and cardiovascular disease. Its flesh is also rich in dietary fiber, which is helpful for relieving constipation and maintaining intestinal health. Gac fruit is suitable for people of all ages, especially those who wear contact lenses for a long time or use computers and mobile phones for a long time.
