Activity 3: Nutrition and ageing (approx. 300 words)

1. The importance of sufficient protein intake in the elderly:
   As we age, our bodies become less proficient at retaining and utilizing protein which is due to a number of components, including a decrease in kidney function, a diminish in muscle mass, & changes in gut health. As a result, older adults got to consume more protein than more youthful adults in arrange to preserve their wellbeing (Bhasin et al., 2018).
   Protein is fundamental for a number of bodily functions, including:
   • Building and maintaining muscle mass.
   • Repairing issue damage.
   • Boosting the immune system
   • Maintaining bone health.
   • Regulating blood sugar levels.
   • Preventing sarcopenia (age-related muscle loss).
2. Protein needs in the elderly:
   The current Australian RDI for protein for adults over 70 is 1.2 grams/kg body weight per day. In anyase, some specialists think this recommendation may be too low, as elderly people may need up to 15 grams of protein/kg of body weight per day (Anthony, 2020). There are a number of a wide range of restrictions to the current RDI for protein within the elderly.
   • First, the RDI is based on the average needs of older adults, and there is individual variation in protein needs.
   • Second, the RDI does not take into account the activity level of older adults.
   • Third, the RDI does not take into account the health status of older adults.
3. Change in the RDI in the elderly compared to adults:
   The RDI for protein is lower in adults than in the elderly because adults are generally more active and have more muscle mass. As we age, we become less active and our muscle mass declines and due to this we need to consume more protein to maintain our health.
4. A diet that has sufficient protein levels for an elderly person should include a variety of protein- rich foods, such as:
   • Breakfast: Greek yogurt with mixed berries and a sprinkle of almonds.
   • Protein breakdown: mixed berries 2g protein; greek yogurt (200g), 10g protein; almonds (10g). 2g protein.
   • Lunch: Grilled chicken breast salad with tomato, cucumber, & mixed greens
   • Protein breakdown: mixed greens and vegetables, 2-4g protein; chicken breast (100g), 31g protein; vinaigrette dressing. Ig protein. greens.
   • Dinner: Baked salmon with quinoa & steamed broccoli.
   • Protein breakdown: steamed broccoli (100 g) provides 3 g of protein; salmon fillet (100g) provides 25g protein; Cooked quinoa (1/2 cup) provides 5 g of protein.
5. Impact of regular physical activity on protein needs:
   A senior's protein requirements may exceed the RDI if they are really active and train often. Because exercise can promote the breakdown of muscle protein, the body need extra protein to rebuild and repair muscle tissue. A senior whexercises frequently and engages in high levels of activity should try to ingest 1.5-2 grammes of protein per kilogramme of body weight per day. This may be accomplished by incorporating a protein supplement after exercise and consuming a range of meals high in protein throughout the day.
