Experts are finding your standard first aid response may be the worst thing you can do in an emergency.Here’s how to update your first aid kit.

　 CUTS AND SCRAPES

　 When the skin isn’t broken，it’s hard to beat iodine (碘酒) for killing bacteria.　　　

doctors use it to clean before surgery.But when there’s a cut，full?strength iodine and rubbing alcohol can be harmful to skin cells，preventing healing.Putting iodine on cuts and wounds kills bacteria，but it won’t clean the wound.The most effective way is washing the wound with water.

　 BURNS

　 If you spread some butter on the burn to ease the pain，it isn’t a good idea.Butter was thought to cool the burn，but it can cause infection and create an environment for bacterial growth.Run the burn under cool water immediately to help remove the heat and put an end to the damaging process. Wrap the burn with a bandage，and keep it clean and dry.If blisters (水泡) form，don’t break them.

　 POISONING

　 When a child swallows anything poisonous，parents probably think they’re well prepared if ipecac (催吐劑) is on hand.Wrong.Ipecac was thought to be a good way to treat a child who had swallowed a poisonous substance，but not any more because it doesn’t always remove the toxic substance.That may cause dehydration (脫水) and prevent doctors from giving other treatments.

　 EXCESS BLEEDING

　 Everyone learns how to stop bleeding with a tourniquet (止血帶).But studies show this method causes more harm than good.Tourniquets can increase the risk of tissue damage or even the loss of a limb.Apply direct pressure to the wound.Simply place a clean cloth on the wound and press firmly；don’t remove the cloth，even if it gets black.If necessary，add more cloths.If that’s not enough，you can further slow the blood flow by applying pressure to the main artery (動(dòng)脈) of the upper arm or leg.

The food we eat seems to have profound effects on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet as well that food is connected with illness is not a new discovery. In 1940’s scientists realized that nitrates（硝酸鹽）, which are often used to keep color of meat, and other additives（添加劑）caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this.
