Final answer:
Adults tend to lose height due to osteoporosis as they age. Maintaining a healthy lifestyle with proper nutrition and physical activity is important for reducing the risk of osteoporosis, obesity, and associated health issues. The correct option is 3.
Step-by-step explanation:
Among the given options, the correct statement that adults require as they age is to lose height due to osteoporosis. Osteoporosis is more common in postmenopausal women due to hormonal changes that reduce bone matrix production, but men are also susceptible to this condition.
While some adults might have a higher fat content and less muscle than they did in their younger years, the other options which suggest adults need to exercise more than when they were younger or eat more sweets, do not accurately represent the needs of aging adults.
In fact, maintaining a healthy lifestyle, including adequate physical activity and proper nutrition, is essential for preventing an array of health issues, including osteoporosis and obesity. Obesity is a complex issue, affected by lifestyle choices such as lack of exercise and overconsumption of carbohydrates and sugary drinks, which can lead to significant health problems like cardiovascular disease, diabetes, and certain cancers.
It is important to encourage healthy habits early on; for instance, maximizing bone mass before the age of 30 can reduce the risk of osteoporosis later in life. Adults should aim to be as lean as possible without becoming underweight, be physically active each day, avoid sugary drinks, eat a variety of nutrient-rich foods, limit consumption of red and processed meats, and moderate alcohol intake.
