Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles.
From the list below, choose all the correct statements about changes in older adults.
Select all that apply.
Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals.
With age, taste and visual perception decline.
As people age, salivary production increases.
In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated.
Lean body mass increases in older adults.
When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well.
From the list below, choose all the correct statements about the effects of increased physical activity or athletic training.
Select all that apply.
An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day.
How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity.
Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake.
Athletes who are following energy-restricted diets are at risk for consuming insufficient protein.
The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.
When taking vitamins and vitamin-mineral supplements, how can one be sure they are getting what they are taking?
