Question

moderate physical activity ______ risk for cardiovascular disease.

• increases
• decreases
• has no effect on
• is less effective than exercise for decreasing

question 8 (1 pts)
high intake of which substance is associated with a decreased risk for cardiovascular (heart) disease?

• saturated fat
• sodium
• fiber
• refined carbohydrates

Explanation:

Analyze the first question on physical activity and cardiovascular risk

Moderate physical activity is clinically proven to strengthen the heart muscle, improve blood circulation, lower blood pressure, and optimize cholesterol levels. These physiological adaptations directly lower the likelihood of developing heart conditions. Therefore, moderate physical activity decreases the risk for cardiovascular disease.

Analyze the second question on dietary substances and cardiovascular risk

High intakes of saturated fats, sodium, and refined carbohydrates are well-documented dietary risk factors that elevate blood pressure, promote arterial plaque buildup, and increase cardiovascular disease risk. Conversely, dietary fiber (especially soluble fiber) helps lower blood cholesterol levels and improves glycemic control, which is strongly associated with a decreased risk of cardiovascular disease.

Answer:

Question 1

• increases
• decreases (Correct answer)
• has no effect on
• is less effective than exercise for decreasing

Question 2
