Q:According to the USDA, there is no difference between a “portion” and a “serving.” True or False?
A:False. A “portion” is how much food you choose to eat at one time, whether in a restaurant, from a package, or in your own kitchen. Versus a portion, a “serving” size is the amount of food listed on a product's Nutrition Facts. Sometimes, the portion size and serving size match; sometimes they do not. Keep in mind that the serving size on the Nutrition Facts is not a recommended amount of food to eat. It is a quick way of letting you know the calories and nutrients in a certain amount of food.
Q:A serving of what kind of vegetables should be about the size of a baseball?
A:A Serving of Broccoli. A serving of broccoli should be about the size of a baseball, which is equivalent to about one cup.
Q:From which foods can we get carbohydrates?
A:Milk products and fruits, whole grain breads and cereals, table sugar, starchy vegetables, and legumes. Carbohydrates are called "simple" or "complex," depending on how fast your body digests and absorbs the sugar. You get simple carbohydrates from fruits, milk products, and table sugar. Complex carbohydrates include whole grain breads and cereals, starchy vegetables, and legumes. Complex carbohydrates and some simple carbohydrates provide vitamins, minerals, and fiber. Products made with refined sugar provide little nutrition. It is wise to limit these products.
Q:Which has more calories: A plain bagel with cream cheese or a toaster waffle with syrup?
A:A Toaster Waffle with Syrup. A 4-inch regular toaster waffle with syrup has 129 calories.
Q:A good rule of thumb is to drink 10-12 glasses of water per day. True or False?
A:False. There is no evidence to show that drinking 10-12 glasses of water is necessary. Generally, nutritionists recommend we follow the “8x8” rule, which is to drink eight 8-ounce glasses of water per day. Drinking more water does indeed boost metabolism - especially if your glass is icy cold. Your body must work to warm the water up, burning a few extra calories in the process. As for other benefits of water, 85% of your brain tissue is water, which means that if you're dehydrated, both your body and your mind will be stressed.
Q:According to the USDA’s famous Food Pyramid, we need 2-3 servings of which food group every day?
A:Milk, cheese, and yogurt products. The USDA's famous Food Pyramid confirms that we need 2-3 daily servings from the milk, yogurt, and cheese group; 2-3 daily servings from the meat, poultry, fish, dry beans, eggs, and nuts group; 3-5 daily servings of vegetables; 2-4 servings from the fruit class; 6-11 daily servings from the bread, cereal, rice, and pasta category, and to use fats, oils, and sweets very sparingly.
