常吃披薩餅會對身體健康有影響嗎?
Pizza is healthy. And it isn't healthy.
披薩很健康，但也不健康。Depending on the type of crust, the amount of cheese and the toppings used, pizza can rank anywhere from nutritionally decent to a diet disaster.
這取決於它餅皮的類型、芝士的量和餅皮上的食材，披薩可以營養豐富，也可以是健康飲食的剋星。Even healthy pizzas deliver a good amount of sodium from tomato sauce and cheese, so if you are watching your salt intake, you should eat with caution. Of course, the size of the slice and the number of slices you eat count, too.
因爲健康披薩的番茄醬和芝士中含有豐富的鈉，所以如果你在控制鈉的攝入量的話，吃披薩時你就該小心了。當然，披薩塊的大小和你吃的數量同樣應該考慮進去。
Pizza pros include the fact that it offers calcium from cheese and disease-fighting lycopene from tomatoes.
披薩的優點在於，它裏面的芝士富含鈣元素，番茄中的番茄紅素則有抵抗疾病的功效。And pizza crust made with whole-wheat flour (including whole white wheat flour) is healthier than regular white crust, as it offers whole grains and fiber and is digested more slowly than refined grains.
由全麥麪粉（包括全麥白麪粉）做成的餅皮比普通精白麪粉做成的餅皮要健康，它能爲我們提供全穀物和纖維素，而且比細糧消化得更慢。
But what you put on your pizza can significantly impact its nutritional value.
但是你在披薩上所放的食材可以在很大程度上影響披薩的營養價值。Toppings such pepperoni, sausage and extra cheese can boost saturated fat, sodium and calories, while slices made with thinner crusts and topped with veggies tend to have lower calorie, saturated fat and sodium counts.
諸如意大利辣香腸、香腸和過量的芝士含有很多飽和脂肪、鈉以及卡路里。薄一點的餅皮上配蔬菜會含有更低的卡路里、飽和脂肪和鈉含量。For example, a large slice of Pizza Hut's Thin 'N Crispy Veggie Lovers pizza has 240 calories, 4 grams of saturated fat and 710 milligrams of sodium.
舉個例子，一大塊Pizza Hunt's的素薄餅披薩含有240卡路里，4克飽和脂肪和710毫克鈉。But a large slice of the chain's Meat Lovers pan pizza with pepperoni, sausage, ham, bacon, pork and beef has 480 calories, 10 grams of saturated fat and 1,180 milligrams of sodium.
但是同樣來自Pizza Hunt's的一大塊包含意大利辣香腸，香腸，火腿，培根，豬肉以及牛肉的披薩，則包含480卡路里，10克反式脂肪以及1180毫克鈉。Frozen pizzas can be a convenient dinner, but they too can vary in terms of ingredients and nutritional value, especially with sodium counts, so it's important to read labels carefully (some contain small amounts of trans fats, too).
速凍披薩可以是簡易晚餐的選擇，但他們同樣可以包含不同的食材，因此也有着不同的營養價值，特別是鈉含量的多少，因此仔細看營養成分表就很重要（其中一些反式脂肪也很少）。When it comes to kids and pizza, one recent study concluded that pizza consumption among children and adolescents was associated with a higher daily calorie intake and higher intakes of saturated fat and sodium. The study also found that pizza eaten as a snack or from fast-food restaurants had the greatest negative impact on calorie intake.
提到孩子，最近一項研究顯示披薩的攝入量使得兒童和青少年每天攝入較高的卡路里、反式脂肪和鈉。該項研究還表明把披薩當零食吃，或者快餐店的披薩都對控制卡路里的攝入很不利。Pizza consumed in schools did not significantly affect children's calorie intake, probably because it may not be that nutritionally different from other school entrees, according to study authors.
據一位研究員所述，在校生的披薩攝入量並沒有很大程度地影響到他們的卡路里攝入情況，也許是因爲披薩的營養價值和他們平時在學校裏吃的東西差不多。If you enjoy pizza on a regular basis, try making it at home using healthier ingredients, such as whole-wheat English muffins, part-skim mozzarella cheese and tomato sauce without added salt. And don't forget to top it with lots of vegetables; the more colorful your pizza, the better!
如果你平時定期就想吃頓披薩，儘量在家裏自己做，用些健康的食材，比如全穀物的英國鬆餅，部分脫脂的馬蘇裏拉奶酪以及不加鹽的番茄醬。別忘了多多加上蔬菜，披薩的顏色越多樣，越健康！
