What It's All About
Bone-strengthening activity — any activity that produces a force on the bones and promotes bone growth and strength. This force is produced most often by impact on the ground in activities like running and jumping.
Calcium — a mineral that helps to form bones and keeps them hard and strong. Most of the calcium in the body is stored in bones and teeth. The remaining calcium is contained in body tissues, blood, and other body fluids. Calcium can be found in some foods and drinks.
Lactose intolerance — a in which the body does not easily digest foods that contain lactose, which is the natural sugar found in dairy products. People who are lactose intolerant have a shortage of enzymes that break down lactose into sugars. Common symptoms include nausea, cramps, bloating, gas, and diarrhea.
Milligram (mg) — a unit of measure used to show the amount of calcium and other vitamins and minerals in foods. There are 1,000 milligrams in a gram. One cup (8 ounces) of milk contains 300 milligrams of calcium.
Mineral — a nutrient essential in small amounts for good nutrition and health. Examples of minerals include calcium, iron, potassium, sodium, and zinc. Like vitamins, the best way for minerals to enter the body is through food.
Nicotine — the drug in tobacco leaves. Whether someone smokes, chews, or sniffs tobacco, he or she is delivering nicotine to the brain. Each cigarette contains about 10 milligrams of nicotine. According to the National Institute on Drug Abuse, more than 3.5 million teens between the ages of 12 and 17 use tobacco.
Nutrition Facts Panel — also known as a "food label" or "nutrition label," this label on food packages lists the nutrients in a food or drink, such as vitamins, minerals, and other components such as calories, sugar, fat, and protein.
Osteoporosis — a disease in which bones become fragile and more likely to break. These broken bones, or fractures, typically occur in the hip, spine, and wrist. Both men and women are at risk, but women are 2-3 times more likely than men to develop osteoporosis. Building strong bones during childhood can help prevent osteoporosis later in life.
Percent Daily Value (% DV) — the "% DV" on the Nutrition Facts Panel is a number that indicates if there is a lot or a little of a nutrient (like calcium) in a serving of food: 5% DV or less of a nutrient is considered low; 20% DV or more is high. If the label says, "Calcium 4%," that means one serving of the food has 4% of the calcium that a person needs in a day. However: (1) the percentage is calculated for an adult, who needs 1,000 milligrams of calcium per day and (2) girls need more calcium than most adults, so help them strive to get 1,300 milligrams of, or 130% DV for, calcium. Visit the FDA and Kids Health for Parents to read more about food labels.
Serving size — serving size, shown on a Nutrition Facts Panel (food label), is the amount of food that people typically eat. The information on a food label (such as calcium, vitamins, and fat) is for one serving. Serving sizes can be shown in different ways for different foods — "slices" of cheese or "ounces" of juice, for example.
Type 2 diabetes — the most common form of diabetes; in type 2, the body either does not make enough insulin (a hormone that helps change sugar and food into the energy needed to live) or the cells ignore the insulin.
Vitamin — a nutrient essential in small amounts for good nutrition and health. Examples of vitamins include vitamin D, vitamin C, and vitamin K. Like minerals, the best way for vitamins to enter the body is through food.
