Which point is important for older adults regarding healthy nutrition?

The importance of avoiding grapefruit and grapefruit juice for older adults primarily stems from its potential interaction with various medications commonly prescribed to this population. Grapefruit contains compounds that can inhibit certain enzymes in the liver that metabolize medications. This can lead to higher levels of drugs in the bloodstream, increasing the risk of side effects or toxicity. For older adults, who often take multiple medications, this interaction can be particularly significant and may result in adverse health effects.

In contrast to the chosen answer, increasing carbohydrates for energy might seem beneficial, but it is crucial that older adults balance their carbohydrate intake with other macronutrients—especially protein and healthy fats—to maintain overall health and muscle mass. Decreasing protein intake is typically not recommended; in fact, higher protein intake can support muscle health and prevent sarcopenia. Limiting fluids may be necessary in certain medical conditions, but for many older adults, adequate hydration is essential to maintain health and prevent complications.
