Much of our good health depends on the cooperation（协同作用） between substances（物质）. When they work together ,chemical reactions（反应） take place smoothly. Body systems are kept in balance. Some of the most important helpers in the job of good health are the substances we call vitamins.
Vitamin A is needed to produce a light –sensitive substance in the eyes. People who do not get enough vitamin A can’t see well in the dark. The best source(来源) of vitamin A is fish liver oil. It is also found in the yellow part of eggs. What’s more, squash, sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.
Vitamin B-1 is also called thiamine. It changes starchy foods into energy. It also helps the heart and nervous system work smoothly. Without it, we would be weak and would not grow. Thiamine is found not just in whole grains like brown rice, but also in other foods. These include beans and peas, nuts and meat and fish.
VitaminB-12 is needed so folic acid can do its work. Together , they help produce red blood cells. Without them, a person suffers from anemia(贫血)。VitaminB-12 is found naturally in foods such as eggs, meat, fish and milk products.
Vitamin C is necessary for strong bones and teeth, and for healthy blood vessels. It also helps wounds heal quickly. The body stores very little Vitamin C. so we must get it very day in foods such as citrus, tomatoes and uncooked cabbage.

As you are soon on your way to Eastern Europe, here are a few tips on what you should pack. In general, pack lightly, with only the most basic clothes. People dress casually(随便地) in Eastern Europe, so you don’t need to bring along your smartest clothing.
Batteries: If your camera, flash, or other appliances run on batteries, bring enough supply along. Certain types of batteries don’t exist in Eastern Europe, and those that do often don’t last very long.
Cash: We have found it good to have supply of small-unit U.S. bills($1and $5) to use in hard–currency stores, to buy international train tickets, etc. The hard–currency stores never seem to have the right change.
Electric Current Adapter(转换器): If you bring any appliances, remember that the electricity in Eastern Europe uses 220 volts A.C., not the standard 110 volts of North America. A 110 volts appliance will soon burn out when attached to an unchanged 220-volt plug.
Language Tools: One of Europe’s biggest challenges is communicating with the local people since their languages are so different from our own. To help overcome difficulties, you might buy phrasebooks before you go — you won’t find them once you are in Eastern Europe.
Money Belt: A money belt is especially helpful when you have many documents to carry around ( as you always do in Eastern Europe). The best one we find is made by Eagle Greek Travel Gear, 143 Cedros Ave. (P. O. box 651), Solona Beach, CA 92075 (tel. 619/755 – 9399, or toll free 800/874 – 9925) outside California.
Traveler’s Checks: These are necessary. Bring your traveler’s checks in small to medium unit ($10, $20, or $50) to change a little bit at a time, so as not to be left with a lot of local money. To be on the safe side, be sure to copy down the check numbers in two places, just in case something happens to the checks.
