According to the key findings of the Australian Institute of Health and Welfare, 1 out of 6 Australians belong to the older adult segment, aged 65 and above. Of this number, more than half are women. The ageing population trend is continuing to rise, so much so that it is projected that the older adult population in Australia will comprise anywhere between 21 to 23% of the total population by 2066. This significant development can be attributed to several factors, including increasing longevity, the baby boom of the 50s and 60s, and a falling birth rate.
As we age, our bodies undergo numerous changes that affect our nutritional needs and dietary habits. Maintaining a balanced and nutritious diet is crucial for healthy ageing, ensuring that older adults remain active, healthy, and independent for as long as possible.
Malnutrition is of special concern as 1.2 million older adults are found to be either malnourished or at risk of malnutrition. In particular, older adults require more protein to help them maintain their muscle mass; sufficient calcium, vitamin D, and vitamin B2 to maintain bone strength, and enough calories to prevent unintentional weight loss.
In this post, we will explore the common dietary problems faced by the elderly, the different ways to improve digestion, the foods to avoid, methods to increase appetite, and the overall nutritional needs of the elderly. Additionally, we will highlight the vital role of dietitians in Aged Care.
Common dietary problems in the elderly
Elderly individuals often face a range of dietary problems that can impact their overall health and wellbeing.
| Common dietary issues
among older adults |
Dietitian’s recommendations |
| Poor appetite
Many older adults experience a decrease in appetite, which can lead to inadequate calorie and nutrient intake. |
• Eating small, frequent meals — Encourage eating smaller portions more often throughout the day to avoid overwhelming the appetite.
• Nutrient-dense foods – Focus on foods high in calories and nutrients, such as nuts, avocados, and full-fat dairy products.
• Making use of appetising food presentations – Make meals visually appealing and aromatic to stimulate the senses and appetite.
• Setting a meal routine – Establish regular mealtimes to create a routine and help stimulate hunger cues.
• Using flavour enhancers – Use herbs, spices, and healthy sauces to make food more flavourful and appealing. |
| Difficulty chewing and swallowing
Dental problems and conditions like dysphagia can make it hard to eat certain foods. |
• Eating soft foods – Incorporate softer foods like mashed potatoes, yoghurt, scrambled eggs, and smoothies that are easier to chew and swallow.
• Use moistening agents – Add gravies, sauces, or broths to dry foods to make them easier to swallow.
• Consuming pureed or minced foods – Modify the texture of foods by pureeing or mincing to reduce the effort required for chewing.
• Dental care – Ensure regular dental check-ups and proper oral hygiene to address any dental issues that may impact eating.
• Use of swallowing techniques – Work with a speech therapist to learn specific techniques and exercises that can help improve swallowing. |
| Altered sense of taste and smell
Changes in taste and smell can reduce the enjoyment of food, leading to reduced food intake. |
• Employ a variety of flavours – Use various herbs, spices, and seasonings to enhance the flavour of foods without adding extra salt or sugar.
• Use temperature contrasts – Serve foods at different temperatures, such as warm soups and cold salads, to provide sensory contrast and enhance the eating experience.
• Tap into a variety of textures – Incorporate different textures, such as crunchy, smooth, and creamy, to make meals more interesting and enjoyable.
• Use aroma to enhance palatability and enjoyment — Cook with aromatic ingredients like garlic, onions, and herbs to stimulate the sense of smell and appetite.
• Eat meals on a regular schedule — Maintain a regular eating schedule to help establish hunger cues despite changes in taste and smell. |
| Digestive issues
Conditions like constipation, gastroesophageal reflux disease (GERD), and slowed digestion are prevalent among the elderly. |
• Eat a high-fibre diet – Include plenty of fruits, vegetables, whole grains, and legumes to promote regular bowel movements and prevent constipation.
• Hydrate well – Encourage adequate fluid intake, aiming for at least 8 glasses of water per day, to support digestion and prevent dehydration.
• Use probiotics – Incorporate probiotic-rich foods like yoghurt, kefir, and fermented vegetables to maintain a healthy gut microbiome.
• Consume smaller meals – Eating smaller, more frequent meals can help prevent overloading the digestive system and reduce symptoms of GERD and indigestion.
• Incorporate physical activity in your daily life – Encourage regular physical activity, such as walking, to stimulate digestion and alleviate constipation. |
| Chronic diseases
Diabetes, heart disease, and hypertension require dietary modifications, which can be challenging to manage. |
FOR DIABETES MANAGEMENT:
• Eat a balanced diet — Emphasise a balanced diet with controlled carbohydrate intake, focusing on whole grains, lean proteins, and plenty of vegetables.
• Glycemic Control – Choose foods with a low glycemic index to help maintain stable blood sugar levels.
• Exercise portion control — Practice portion control to avoid blood sugar spikes and maintain a healthy weight.
• Do regular monitoring – Monitor blood sugar levels regularly and adjust the diet as needed in consultation with a healthcare provider. Also make sure you have regular diabetes/foot health checks for your feet.
FOR HEART DISEASE MANAGEMENT:
• Eat a low-sodium diet – Reduce sodium intake by avoiding processed foods, canned soups, and salty snacks.
• Have health fats – Incorporate heart-healthy fats from sources like avocados, nuts, seeds, and olive oil while avoiding trans fats and saturated fats.
• Up your fibre intake – Increase dietary fibre intake to help manage cholesterol levels and support heart health.
• Eat a balanced diet – Follow a balanced diet rich in fruits, vegetables, whole grains, and lean proteins to support cardiovascular health.
FOR HYPERTENSION MANAGEMENT:
• Use the DASH Diet: Follow the Dietary Approaches to Stop Hypertension (DASH) diet, which emphasises fruits, vegetables, whole grains, and lean proteins.
• Limit sodium – Reduce sodium intake to less than 2,300 milligrams per day, or lower if advised by a healthcare provider.
• Consume potassium-rich foods – Include potassium-rich foods like bananas, potatoes, and leafy greens to help balance sodium levels and manage blood pressure.
• Manage your weight – Maintain a healthy weight through a balanced diet and regular physical activity to help manage blood pressure. |
How to improve digestion in advancing/old age
Improving digestion in the elderly can significantly enhance their overall health. Here are some strategies to promote better digestive health in advancing age:
- Hydration – Drinking plenty of water aids digestion and prevents constipation. Aim for at least 8 glasses of water per day.
- Fibre-rich foods – Incorporating fruits, vegetables, whole grains, and legumes can help maintain regular bowel movements.
- Small, frequent meals – Eating smaller meals more frequently can prevent overloading the digestive system and ease digestion.
- Probiotics – Including probiotic-rich foods like yoghurt can support gut health by maintaining a healthy balance of gut bacteria.
- Physical activity – Regular physical activity, such as walking, can stimulate digestion and reduce constipation.
What foods should the elderly avoid and why?
Certain foods can be detrimental to the health of elderly individuals and should be consumed with caution or avoided altogether.
| Foods to avoid | Reasons why |
| Foods high in sodium | Excess sodium can lead to hypertension and cardiovascular problems. Limit processed foods, canned soups, and salty snacks. |
| Sugary foods and beverages | High sugar intake can exacerbate diabetes and lead to weight gain. Avoid sugary snacks, desserts, and sugary drinks. |
| Trans fats | Foods containing trans fats, such as fried foods and baked goods, can increase the risk of heart disease. |
| Alcohol | Excessive alcohol consumption can interfere with medications and exacerbate health conditions. Limit or avoid alcohol intake. |
