Jana, a senior in high school, recently stopped consuming dairy products. She also started smoking, and her physical activity level is low. Jana's diet yesterday (which is typical) consisted of the following items. For breakfast, she had oatmeal made with water, a banana, and a cup of juice. At midmorning, she bought a snack cake from the vending machine. At lunch, she had vegetable pasta, bread with olive oil, small green salad and a soft drink. For dinner, she had a chicken burger with fries and water. For an evening snack she had some cookies and hot tea. What 3 factors place Jana at risk of poor bone health?

1. Stopping consumption of dairy products: Dairy products are a major source of calcium, which is essential for maintaining strong bones. Without an adequate intake of calcium, Jana may be at risk of developing weak bones.

2. Smoking: Smoking has been linked to a decrease in bone density, which can increase the risk of fractures and osteoporosis.

3. Low physical activity level: Physical activity, especially weight-bearing exercises, is important for building and maintaining strong bones. A sedentary lifestyle can lead to decreased bone density and overall poor bone health.
