ATER PURIFICATION The simplest way of purifying water is to boil it thoroughly. Vigorously boiling for five minutes should be satisfactory; however, at high altitude water boils at lower temperatures, so germs are less likely to be killed. Simple filtering will not remove all dangerous organisms, so if you cannot boil water it should be treated chemically. Chlorine tablets (Puritabs, Steritabs or other brand names) will kill many but not all pathogens, including giardia and ameobic cysts
NUTRITION If your food is poor or limited in availability, if you're traveling hard and fast and missing meals, or if your children simply lose their appetite, they can soon start to lose weight and place their health at risk. Make sure you have a well-balanced diet. Eggs, tofu, beans, lentils (dal in India) and nuts are all safe ways to get protein. Fruit you can peel (bananas, oranges or mandarins for example) is always safe and a good source of vitamins
When traveling to an underdeveloped country, make sure that everyone in your traveling party is adequately immunized against any infectious disease you might encounter
Cooked foods are usually safe, but raw foods and salads (lettuce, raw vegetables, fruit with peel, unpasteurized milk, milk products, undercooked seafood or meat) can lead to gastrointestinal problems. Eat in restaurants that have a reputation for safe cooking.
