Meeting Nutritional Needs for the Elderly: Reduce Risk of Chronic Disease, Constipation and Nutritional Deficiencies.

Healthy muscles are very important to ensure that seniors continue to retain their mobility, strength, energy levels, and independence. Aging and poor nutrition are common causes of sarcopenia (loss of muscle and strength).

Older adults often consume less protein than needed, due to reduced appetite, dental problems, or limited food choices​. The Singapore National Nutrition Survey 2022, found that 1 in 2 adults aged 50 to 69 did not meet their recommended protein requirements due to their lower protein intake compounded by higher protein requirements with age.

Top 3 Protein Intake Guides:

1. Quantity – 1.2g per kg body weight (e.g. a 60kg adult will need 72g protein)
2. Quality – focus on quality (e.g. have high quality proteins like fish, lean meat, eggs, dairy, soy and legumes)
3. Timing – distribute your protein intake across 3 to 4 meals and mid-meals rather than have it all at 1 or 2 meals

Bone mineral density declines from 30-40 years of age, increasing the risk of fractures and osteoporosis. Weight-bearing exercises, together with sufficient calcium and vitamin D, help keep your bones stronger and denser.

Weight-Bearing Exercises

Exercises like dancing, brisk walking and jogging cause the body to respond by increasing the density of your bones. Low impact exercises such as walking and low impact aerobics can also help maintain bone density.

Vitamin D

Vitamin D deficiency can occur due to reduced skin synthesis and limited sun exposure. Low levels of vitamin D can lead to osteoporosis, impaired immune function, and muscle weakness.

To meet your daily dose of vitamin D, include eggs, oily fish (Salmon, Mackerel, Sardines or Tuna), liver or vitamin D-fortified food.

For natural Vitamin D synthesis by your body, 10 to 30 minutes of sun exposure, 2 to 3 times per week is recommended.

Calcium

Calcium helps to ensure your muscles, blood vessels, and nerves function well. If you do not consume sufficient calcium, your body will draw the necessary calcium from your bones, in a process known as ‘leeching’. This will result in your bones becoming more brittle over time, and hence, putting you at higher risk for osteoporosis.

Some common sources of calcium are:

* Item may be high in salt. Table above from HealthHub. For more information, find out here.

With age, your body’s ability to digest the milk sugar lactose reduces, resulting in bloatedness, stomach discomfort and diarrhoea. This is a common cause for seniors limiting their milk and dairy consumption, and hence not being able to meet their recommended calcium requirement of 1,000mg a day.

If you are lactose intolerant, try:

1. Milk with other foods such as biscuits
2. Small amounts of milk at a time (e.g., ½ glass of milk per sitting)
3. Low lactose milk

As you age, your basal metabolic rate and physical activity decrease, while your micronutrient needs remain the same or can even increase. Having a variety of well-balanced, nutrient-dense meals is key to meeting energy needs and preventing micronutrient deficiencies.

Constipation occurs when bowel movements become difficult or less frequent. The risk of constipation is increased by slower gut mobility, brought on by aging, and is compounded by reduced fluid and fiber intakes.

Insufficient fluids can lead to constipation, dizziness and falls, Urinary Tract Infections (UTIs) and can worsen kidney function.

As you age, the sensation of thirst reduces. As such, thirst is not a good indicator of hydration. It is also common for the elderly to limit their fluid intake due to a fear of frequent urination or incontinence.

Unless you are advised to restrict fluids by your doctor, you should consume 6-8 cups of fluid a day (25-30ml per kg per day). If you are concerned about frequent night-time urination, drink more during the day.

Meeting your nutritional needs while managing a chronic disease can be a challenge.

Some common challenges are:

1. Balancing restrictions (e.g. Sodium, sugar, saturated fat) with adequate intake​
2. Managing multiple diet messages, which can be confusing​
3. The chronic disease itself may affect appetite

Tips:​

1. Avoid overly-restrictive diets that worsen malnutrition risk​
2. Follow the diet advice given by your treatment team

Medications (either singly or in combination) can affect:​

1. Appetite​
2. Nutrient Absorption​
3. Gastrointestinal Tolerance​

Remember:

1. Do not stop medications on your own​
2. Discuss with your Dr or pharmacist if there is​ unintentional weight loss​, poor appetite & taste changes​ and/or anemia, neuropathy, gastric irritation

1. Eat more plants​

Plants are high in fibre, which provide fuel for “good” gut bacteria, thus promoting bowel health. Brightly-coloured plants also contain polyphenols (antioxidants), which can reduce risk of type 2 diabetes, cancer, and heart disease. ​Aim for 30 different plant foods a week, including nuts, seeds, herbs and spices.

2. Eat prebiotic and probiotic foods

Prebiotics are a type of fibre that fuel “good” bacteria (probiotics). ​

• Prebiotic-rich foods include onions, garlic, leeks, asparagus, Jerusalem artichokes and bananas.​

Probiotics are live bacteria that are found in fermented foods. ​

• Popular fermented foods include fermented vegetables like kimchi or sauerkraut, dairy products such as kefir and live yogurt, and fermented tea (kombucha). 

3. Eat healthy fats

Healthy fats provide energy, support cell growth, help with nutrient absorption, and produce important hormones. ​

• Replace unhealthy animal fats (found in processed meats, butter, and cream), for healthier plant sources of fat (nuts, seeds, avocados and extra virgin olive oil).​

4. Drink less alcohol

Aging can lower alcohol tolerance, and drinking too much alcohol can increase the risk of high blood pressure, cancer, liver disease, and stroke. ​

• Moderate amounts of red wine may have some health benefits, possibly by improving gut health​. However, if you do not already drink alcohol, do not start drinking for its purported health benefits as evidence is emerging that the health benefits of alcohol may be over-rated

5. Follow a Mediterranean-style diet

The Mediterranean diet is an eating pattern that includes plant-based foods such as grains, fruits, vegetables, nuts, seeds, and healthy fats like extra virgin olive oil. ​This eating pattern is easily adopted in Asia as there is a wide variety of locally available and affordable plant foods like kai lan, spinach, chye sim,  guava, papaya, and the humble peanut too!

Other aspects of the Mediterranean diet include eating red meat, unhealthy fats, and processed foods occasionally, and consuming wine (primarily red wine) in moderation

Eat more often	Eat less often
Vegetables & fruits	Red & processed meats (e.g. luncheon meat, char siew
Whole grains (e.g. brown rice, whole meal bread)​	Sugary beverages & desserts (e.g. sweet drinks, desserts)​
Nuts & legumes (e.g. baked cashews, dhal, tau kwa​)	Trans‑fat‑rich snacks (e.g. curry puff, pastries)
Unsaturated fats (e.g. vegetable oils with the Healthier Choice symbol)	High sodium foods (e.g. salty gravies, sauces)​
Fish & low‑fat dairy (in moderation)	Ultra‑processed foods (e.g. packaged snacks, instant foods)

Eating for healthy aging is not about strict rules about what to eat or how much to eat.​

There is no single “best” diet, but diets rich in whole, minimally processed foods are consistently linked to:​

• Better physical function​
• Better cognitive and mental health​
• lower risk of chronic disease
