The reason fruits and vegetables are so important to your overall health is that they are major purveyors of antioxidants.
Antioxidant molecules are like the missile【C1】______system of your body, preventing damage from molecular bombs called free radicals. It works like this: in order to breathe, move, or eat, your body’s cells【C2】______food and oxygen into energy. This chemical reaction releases【C3】______byproducts, the free radicals we mentioned. Basically, they’re highly reactive【C4】______of oxygen that are missing an electron.
【C5】______for that missing electron, they steal them from normal cells, damaging the healthy cell and its
DNA in the【C6】______. This damage eventually【C7】______to any number of major health problems, including heart disease, memory loss, and cancer.
Antioxidants, however,【C8】______with this process by giving free radicals one of their own electrons to stabilize them. Or they combine with free radicals to form different, more【C9】______compounds. There are also antioxidant enzymes that help free radicals react with other chemicals to produce safe, instead of toxic, substances. Antioxidants, for instance, help prevent "bad" LDL cholesterol from becoming【C10】______and forming plaque(斑). This is the reason the health establishment is so insistent on people eating more fresh produce: It provides around-the-clock defenses against free-radical damage to your arteries.
A)change B)contributes C)convert D)defense E)Desirous
F)Desperate G)forms H)harmful I)interfere J)offense
K)participates L)process M)stable N)stickier O)thinner
【C6】
