1. Read the text and match the headings (A-1) to the paragraphs (1-7). There are two extra headings you do not need to use. Pumpkins Are Good for Your Health (1) There is one food that takes the center stage during autumn - the pumpkin! Many people use this orange vegetable as a decoration at Halloween. But we also use it in many foods that are popular during the autumn season - foods like pumpkin bread, pumpkin coffee, pumpkin cookies, pasta made with pumpkin and pumpkin pie. In fact, pumpkin pie is one of the most common desserts at an American Thanksgiving table. (2) But perhaps we should try to eat pumpkin all year long, and not just in autumn. Pumpkins are packed with important nutrients and vitamins. If cooked in a healthy way, without much butter or sugar, pumpkin is very useful for your body. (3) The nutrient beta-carotene and Vitamin A are necessary for maintaining good eyesight. Pump- kins are a great source of both. In fact, one nutrition website says that one cup of cooked, mashed pumpkin can give you more than 200 percent of your daily recommended amount of Vitamin A. (4) The National Cancer Institute in the United States says on its website that antioxidants may help reduce a person's risk of getting cancer. That is because antioxidants neutralize something called free radicals in the body. Antioxidants help to get rid of these free radicals. And as we said earlier, pumpkin is full of beta-carotene as well as vitamin A which are natural antioxidants. (5) Beta-carotene also helps to keep your skin healthy and young-looking. Yet another good reason to eat pumpkin! (6) Pumpkin is also full of potassium. Health experts say that consuming potassium may help treat high blood pressure that is bad for your heart. Pumpkin also has a lot of fiber. Fiber slows down digestion of food. So, when you eat pumpkin. ou feel full and eat less. So, if it is available where you live, try to find ways to include pumpkin in your next meal!

A. All year long decoration.
B. Pumpkin helps your skin.
C. Protection for the heart.
D. Holiday vegetable.
E. Control your weight.
P. Keep it simple.
G. Tasty recipes.
H. Pumpkin is good for your eyes.
I. Protection from a deadly disease.
