Staying engaged with other people can help counter frailty, according to an expert in geriatric medicine. Having a reason to ghet up in the morning helps yhou stay active”, says Dr Linda Fried, dean of Columbia’s School for Public Health. Frailty in old age – more prevalent in women – is not inevitable. Doctors can diagnose it and provide treatment to prevent and sometimes reverse it. It can be caused partly by loss of muscle mass, which is related to aging. Two of the most critical ways to prevent it, says Dr Fried, are exercise and diet. “Walking and resistance training with weights are similar to the benefits of getting a car tuned up: every part of one’s physiology runs better.” It is also important to eat foods such as fish, chicken, vegetables, low dairy products and whole grains each day, rather than carbohydrates.
