The Colors of Health

Fruits and vegetables come in terrific colors and flavors, but their real beauty lies in what's inside. Fruits and vegetables are great sources of many vitamins, minerals and other natural substances that may help protect you from chronic diseases.

To get a healthy variety, think color. Eating fruits and vegetables of different colors gives your body a wide range of valuable nutrients, like fiber, folate, potassium, and vitamins A and C. Some examples include green spinach, orange sweet potatoes, black beans, yellow corn, purple plums, red watermelon, and white onions. For more variety, try new fruits and vegetables regularly.

Gold Fish - Lionhead (Oranda)

The Oranda, or so-called Dutch Lionhea, is one of the largest forms of this variey. It reaches a length of 30 cm, with the length of the tail equalling that of the head and body combined. All the fins are long. The Dutch Lionhead was apparently brought from China to Japan (Nagasaki) by Dutch merchants in the 17th century and bred further in that country.

The papaya is sometimes called papaw or pawpaw, but in the United States these names are generally restricted to Asimina triloba (L.) Dunal (see "Papaw"). Papayas are grown to a limited extent in continental United States. They have been tried in Texas and in California, have never exceeded a few hundred acres even in Florida (Harkness 1967), but are more common in Hawaii and Puerto Rico. The 1964 United States Census of Agriculture showed that 32 farms in Florida produced almost 1.5 million pounds of fruit, while 266 farms in Hawaii produced almost 22 million pounds.

Papayas grow from about 32 deg N. to 32 deg S. latitude, from sea level to 5,000 feet altitude. They are killed by frost but do well in full sun or under irrigation. They do not occur in the wild, probably originated in Mexico or Costa Rica, and now consist of many cultivars (Purseglove 1968*).

The ripe fresh fruit (90 percent water, 4 to 10 percent sugar) (Wolfe and Lynch 1940) is eaten throughout the tropics for breakfast, dessert, in salads, jams, ice creams, and soft drinks. The dried latex or "milk" of immature fruit yields papain, a proteolytic enzyme similar in action to pepsin, which is used as a meat tenderizer (Becker 1958). It also creates shrink-resistance in wool.

Appalachian Fruit Research Station (AFRS)

The mission of the Appalachian Fruit Research Station (AFRS) is to identify critical problems of temperate fruit production; develop the science, technology, and genetic base needed to maximize productivity and quality of fruit crops; and minimize the adverse effects of biotic and environmental factors on these crops.

Chemical Vapor Deposition (CVD)

A method of depositing thin semiconductor films used to make certain types of photovoltaic devices. With this method, a substrate is exposed to one or more vaporized compounds, one or more of which contain desirable constituents. A chemical reaction is initiated, at or near the substrate surface, to produce the desired material that will condense on the substrate.
