Deliciously sweet with musky undertones and a soft, butter-like consistency, it is no wonder the papaya was reputably called the "fruit of the angels" by Christopher Columbus. Once considered quite exotic, they can now be found in markets throughout the year. Although there is a slight seasonal peak in early summer and fall, papaya trees produce fruit year round.
Papayas are spherical or pear-shaped fruits that can be as long as 20 inches. The ones commonly found in the market usually average about 7 inches and weigh about one pound. Their flesh is a rich orange color with either yellow or pink hues. Inside the inner cavity of the fruit are black, round seeds encased in a gelatinous-like substance. Papaya's seeds are edible, although their peppery flavor is somewhat bitter. The fruit, as well as the other parts of the papaya tree, contain papain, an enzyme that helps digest proteins. This enzyme is especially concentrated in the fruit when it is unripe. Papain is extracted to make digestive enzyme dietary supplements and is also used as an ingredient in some chewing gums.
Papayas offer not only the luscious taste and sunlit color of the tropics, but are rich sources of antioxidant nutrients such as carotenes, vitamin C and flavonoids; the B vitamins, folate and pantothenic acid; and the minerals, potassium, copper, and magnesium; and fiber. Together, these nutrients promote the health of the cardiovascular system and also provide protection against colon cancer. In addition, papaya contains the digestive enzyme, papain, which is used like bromelain, a similar enzyme found in pineapple, to treat sports injuries, other causes of trauma, and allergies.
Papayas may be very helpful for the prevention of atherosclerosis and diabetic heart disease. Papayas are an excellent source of the powerful antioxidants vitamin C and vitamin A (through their concentration of pro-vitamin A carotenoid phytonutrients).
These nutrients help prevent the oxidation of cholesterol. Only when cholesterol becomes oxidized is it able to stick to and build up in blood vessel walls, forming dangerous plaques that can eventually cause heart attacks or strokes. One way in which dietary vitamin E and vitamin C may exert this effect is through their suggested association with a compound called paraoxonase, an enzyme that inhibits LDL cholesterol and HDL cholesterol oxidation.
Papayas are also a good source of fiber, which has been shown to lower high cholesterol levels. The folic acid found in papayas is needed for the conversion of a substance called homocysteine into benign amino acids such as cysteine or methionine. If unconverted, homocysteine can directly damage blood vessel walls and, if levels get too high, is considered a significant risk factor for a heart attack or stroke.
The nutrients in papaya have also been shown to be helpful in the prevention of colon cancer. Papaya's fiber is able to bind to cancer-causing toxins in the colon and keep them away from the healthy colon cells. In addition, papaya's folate, vitamin C, beta-carotene, and vitamin E have each been associated with a reduced risk of colon cancer.
These nutrients provide synergistic protection for colon cells from free radical damage to their DNA. Increasing your intake of these nutrients by enjoying papaya is an especially good idea for individuals at risk of colon cancer.
Papaya contains several unique protein-digesting enzymes including papain and chymopapain. These enzymes have been shown to help lower inflammation and to improve healing from burns. In addition, the antioxidant nutrients found in papaya, including vitamin C and beta-carotene, are also very good at reducing inflammation. This may explain why people with diseases that are worsened by inflammation, such as asthma, osteoarthritis, and rheumatoid arthritis, find that the severity of their condition is reduced when they get more of these nutrients.
Vitamin C and vitamin A, which is made in the body from the beta-carotene in papaya, are both needed for the proper function of a healthy immune system. Papaya may therefore be a healthy fruit choice for preventing such illnesses as recurrent ear infections, colds and flu.
Your mother may have told you carrots would keep your eyes bright as a child, but as an adult, it looks like fruit is even more important for keeping your sight. Data reported in a study published in the Archives of Ophthalmology indicates that eating 3 or more servings of fruit per day may lower your risk of age-related macular degeneration (ARMD), the primary cause of vision loss in older adults, by 36%, compared to persons who consume less than 1.5 servings of fruit daily. In this study, which involved over 110,000 women and men, researchers evaluated the effect of study participants' consumption of fruits; vegetables; the antioxidant vitamins A, C, and E; and carotenoids on the development of early ARMD or neovascular ARMD, a more severe form of the illness associated with vision loss. While, surprisingly, intakes of vegetables, antioxidant vitamins and carotenoids were not strongly related to incidence of either form of ARMD, fruit intake was definitely protective against the severe form of this vision-destroying disease. Three servings of fruit may sound like a lot to eat each day, but papaya can help you reach this goal. Add slices of fresh papaya to your morning cereal, lunch time yogurt or green salads. Cut a papaya in half and fill with cottage cheese, crab, shrimp or tuna salad. For an elegant meal, place slices of fresh papaya over any broiled fish.
While one study suggests that high doses of supplemental vitamin C makes osteoarthritis, a type of degenerative arthritis that occurs with aging, worse in laboratory animals, another indicates that vitamin C-rich foods, such as papaya, provide humans with protection against inflammatory polyarthritis, a form of rheumatoid arthritis involving two or more joints.
The findings, presented in the Annals of the Rheumatic Diseases were drawn from a study of more than 20,000 subjects and focused on subjects who developed inflammatory polyarthritis and similar subjects who remained arthritis-free during the follow-up period. Subjects who consumed the lowest amounts of vitamin C-rich foods were more than three times more likely to develop arthritis than those who consumed the highest amounts.
Choosing to regularly eat lycopene-rich fruits, such as papaya, and drink green tea may greatly reduce a man's risk of developing prostate cancer, suggests research published the Asia Pacific Journal of Clinical Nutrition (Jian L, Lee AH, et al.)
In this case-control study involving 130 prostate cancer patients and 274 hospital controls, men drinking the most green tea were found to have an 86% reduced risk of prostate cancer compared, to those drinking the least.
A similar inverse association was found between the men's consumption of lycopene-rich fruits and vegetables such as tomatoes, apricots, pink grapefruit, watermelon, papaya, and guava. Men who most frequently enjoyed these foods were 82% less likely to have prostate cancer compared to those consuming the least lycopene-rich foods.
Regular consumption of both green tea and foods rich in lycopene resulted in a synergistic protective effect, stronger than the protection afforded by either, the researchers also noted.
Practical Tips: Get in the habit of drinking green tea and eating lycopene-rich foods.
Papayas are fruits that remind us of the tropics, the regions of the world in which they are grown. Once considered an exotic fruit, papayas' rise in popularity has made them much more available.
Papayas are spherical or pear-shaped fruits that can be as long as 20 inches. The ones commonly found in the market usually average about 7 inches and weigh about one pound. Their flesh is a rich orange color with either yellow or pink hues.
Papaya has a wonderfully soft, butter-like consistency and a deliciously sweet, musky taste. Inside the inner cavity of the fruit are black, round seeds encased in a gelatinous-like substance. Papaya's seeds are edible, although their peppery flavor is somewhat bitter.
The fruit, as well as the other parts of the papaya tree, contain papain, an enzyme that helps digest proteins. This enzyme is especially concentrated in the fruit when it is unripe. Papain is extracted to make digestive enzyme dietary supplements and is also used as an ingredient in some chewing gums.
Papayas, native to Central America, have been long revered by the Latin American Indians. Spanish and Portuguese explorers brought papayas to many other subtropical lands to which they journeyed including India, the Philippines, and parts of Africa.
This revered tropical fruit was reputably called "the fruit of the angels" by Christopher Columbus. In the 20th century, papayas were brought to the United States and have been cultivated in Hawaii, the major U.S. producer since the 1920s. Today, the largest commercial producers of papayas include the United States, Mexico and Puerto Rico.
If you want to eat them within a day of purchase, choose papayas that have reddish-orange skin and are slightly soft to the touch. Those that have patches of yellow color will take a few more days to ripen.
Papayas that are totally green or overly hard should not be purchased, unless you are planning on cooking them, or unless you want to use green papayas in a cold dish like an Asian salad, as their flesh will not develop its characteristic sweet juicy flavor.
While a few black spots on the surface will not affect the papaya's taste, avoid those that are bruised or overly soft. Papayas are more available during the summer and fall; however, you can usually purchase them throughout the year.
At WHFoods, we encourage the purchase of certified organically grown foods, and papaya is no exception. Repeated research studies on organic foods as a group show that your likelihood of exposure to contaminants such as pesticides and heavy metals can be greatly reduced through the purchased of certified organic foods, including papaya. In many cases, you may be able to find a local organic grower who sells papaya but has not applied for formal organic certification either through the U.S. Department of Agriculture (USDA) or through a state agency. (Examples of states offering state-certified organic foods include California, New York, Oregon, Vermont, and Washington.) However, if you are shopping in a large supermarket, your most reliable source of organically grown papaya is very likely to be papaya that displays the USDA organic logo.
Papayas that are partially yellow should be left at room temperature where they will ripen in a few days. If you want to speed this process, place them in a paper bag with a banana. Ripe papayas should be stored in the refrigerator and consumed within one or two days, so you can enjoy their maximum flavor.
Papayas can be used many different ways. They can be eaten as is, added to a fruit salad or to a host of different recipes.
One of the easiest (and most delightful) ways to eat papaya is to eat it just like a melon. After washing the fruit, cut it lengthwise, scoop out the seeds and then eat it with a spoon. For a little extra zest, you can squeeze lemon or lime juice on top.
To cut papaya into smaller pieces for fruit salad or recipes, first peel it with a paring knife and then cut into desire size and shape. You can also use a melon baller to scoop out the fruit of a halved papaya. If you are adding it to a fruit salad, you should do so just before serving as it tends to cause the other fruits to become very soft.
While most people discard the big black seeds, they are actually edible and have a delightful peppery flavor. They can be chewed whole or blended into a creamy salad dressing, giving it a peppery flavor.
