Why Do Elderly People with Dysphagia Need More Protein?

Protein is essential for maintaining muscle mass, immune function and wound healing. Elderly people with dysphagia face a double challenge: age itself increases protein requirements, while a modified-texture diet severely restricts access to high-protein foods such as meat, nuts and legumes.

Sustained protein deficiency produces the following consequences:

• Sarcopenia: Progressive muscle mass and strength loss, increasing the risk of falls and functional dependency
• Weakened immunity: Greater susceptibility to infections including aspiration pneumonia
• Delayed wound healing: Impaired recovery from surgery, pressure injuries and fractures
• Fatigue and cognitive decline: Affecting daily function and quality of life

Protein Intake Targets for Elderly Patients

The general adult recommended protein intake is 0.8 g per kilogram of body weight per day. For older adults and those with medical conditions, the targets are substantially higher:

Example: A patient weighing 52 kg has a general daily protein target of 52–62 g. With active pressure injuries, that target can rise to 78–104 g per day.

Protein Content of Common Modified-Texture Foods in Hong Kong

The following foods can provide meaningful protein without changing the patient’s IDDSI level:

Strategies for Increasing Protein in a Modified-Texture Diet

Strategy 1: Choose Naturally High-Protein, Soft Foods

In Cantonese cuisine, several ingredients are naturally soft-textured and protein-rich:

• Eggs: Steamed egg custard, steamed dessert egg, mixed into congee — versatile and IDDSI Level 4 compatible
• Fish: Steamed deboned white fish fillet (ensure thorough deboning every time)
• Minced pork or chicken: Steamed minced patty, stirred into congee; can achieve IDDSI Level 5
• Silken tofu: Naturally Level 4 texture; provides both protein and calcium
• Unsweetened soya milk: Liquid protein source; must be thickened to the prescribed IDDSI level

Strategy 2: Add Protein Fortifiers

The following additions increase protein content without changing the food’s IDDSI level:

Full-cream milk powder:

• 2 tablespoons provides approximately 5–7 g of protein
• Stir into congee, steamed egg custard or vegetable purée
• Simultaneously boosts energy and calcium intake

Unflavoured protein powder (whey or pea protein):

• Choose unsweetened varieties that dissolve completely in liquids
• Stir into purées or thickened drinks
• Each serving (~20–25 g) can add 15–20 g of additional protein

Medical protein modules:

• Pharmaceutical-grade protein concentrates; available at Hong Kong pharmacies and medical supply retailers
• Used on top of an otherwise balanced diet to supplement targeted protein
• Should be used under medical or dietitian guidance

Strategy 3: Use Frequent Small Meals

Dysphagia patients typically eat small portions per sitting, making it difficult to reach protein targets across only three meals. Recommended approach:

• Distribute intake across 5–6 eating occasions per day, each containing a protein source
• Avoid using plain congee or pure starch foods as the entire meal — always include egg, fish, minced meat or tofu
• Mid-afternoon snacks can consist of steamed egg custard or thickened soya milk

Preparing Common Protein Sources (Hong Kong Households)

Steamed Egg Custard (IDDSI Level 4)

1. Beat 2 whole eggs, add an equal volume or 1.5 times the volume of de-fatted clear chicken stock
2. Sieve to remove air bubbles and any chalaza
3. Steam over low-medium heat for 8–10 minutes until just set
4. A small amount of ginger-soy sauce may be added for flavour (note the liquid’s IDDSI level)

Protein yield: approximately 14–16 g (2 eggs with chicken stock)

Steamed Fish Fillet (IDDSI Level 5–6)

1. Choose low-bone fish (threadfin, grass carp)
2. Remove all bones thoroughly — check at least twice — cut into pieces smaller than 1 cm
3. Add a little ginger and spring onion; steam on medium heat for 6–8 minutes
4. After steaming, apply the fork pressure test before serving

Important: Fish bones are a high-risk choking hazard for dysphagia patients. Thorough deboning is non-negotiable every time.

Micronutrients: What Else to Monitor Alongside Protein

While increasing protein intake, the following micronutrients are also commonly deficient in modified-texture diets:

When to Request a Dietitian Referral

Request a referral to a registered dietitian in the following situations:

• The patient has lost more than 5% of body weight in 3 months
• The patient’s food intake is consistently well below requirements
• The patient has diabetes, chronic kidney disease or another condition requiring specialised dietary management
• The caregiver is unsure how to meet protein targets within IDDSI dietary constraints
• Nasogastric tube feeding or enteral nutrition is being considered

Referral Pathways in Hong Kong

Frequently Asked Questions

Q: Can elderly dysphagia patients take protein bars or gym protein supplements?

A: Most commercial protein bars have a hard texture (IDDSI Level 7 or above) and are entirely unsuitable. Gym protein powders are formulated for younger athletic users and typically contain high amounts of artificial sweeteners. If protein supplementation is needed, choose an unflavoured, fully soluble medical-grade or food-grade protein powder and use it under dietitian guidance.

Q: Does increasing protein intake damage the kidneys?

A: For patients with normal kidney function, intakes of 1.0–1.5 g/kg body weight are considered safe. Patients with chronic kidney disease (CKD) require protein restriction — their protein targets should be jointly determined by their nephrologist and dietitian. Do not significantly increase protein intake without first consulting the medical team.

Q: Is tofu sufficient as a meat substitute for protein?

A: Silken tofu is a valuable plant-based protein source, but at approximately 5–6 g per 100 g it has a significantly lower protein density than meat (15–20 g per 100 g). Using tofu as the primary protein source requires larger portions or concurrent fortification strategies such as milk powder or protein powder to meet daily targets.

Q: Is it safe to eat steamed egg every day?

A: Yes, for most patients. Eggs do not need to be strictly limited unless a physician has advised otherwise for cardiac or other medical reasons. One to two eggs per day is reasonable for a healthy elderly person. Eggs provide high-quality protein, vitamin D, vitamin B12 and choline — they are an extremely practical ingredient in modified-texture diets.

Q: Which oral protein supplements are available from Hong Kong pharmacies?

A: Multiple products are available at pharmacy chains (Mannings, Watsons) and medical supply retailers. When selecting, consider: whether thickening is required before serving (most liquid supplements are IDDSI Level 0), sugar and artificial sweetener content, and whether a prescription or dietitian recommendation is required. Consult the attending physician or dietitian for specific product guidance.
