How much protein should older adults eat each day?

A general recommendation is approximately 1–1.2 grams per kilogram of body weight per day. For example, a 60-kilogram person would receive about 60–72 grams per day, distributed across all meals, from easily digested sources such as fish, eggs, tofu, and low-fat milk.

What should be eaten to support bowel movements and blood-sugar control?

Increase fibre from leafy green vegetables, fresh fruit such as apples, guava, and bananas, and whole grains such as brown rice and oats to support bowel movements and help control blood sugar and blood lipids.

Which foods and drinks should be avoided?

Avoid fried foods, saturated and trans fats, high-sodium foods such as processed foods and strongly flavoured seasonings, and high-sugar drinks such as soft drinks and sweet milk tea because they increase the risk of heart disease, diabetes, and high blood pressure.

How much water should older adults drink each day?

Generally, approximately 1.5–2 litres, or 6–8 glasses, should be sipped throughout the day. This should be adjusted according to medical advice when kidney disease or fluid restrictions are present.

Why should meals be eaten on time?

Eating on time helps medications act appropriately, reduces blood-sugar fluctuations and faintness or fatigue, and improves hunger control.

How should food be adjusted when diabetes, high blood pressure, or kidney disease is present?

Consult a doctor or dietitian for an individualised menu, such as restricting sodium for high blood pressure, controlling sugar for diabetes, and potentially limiting protein or potassium for kidney disease.

What Should Older Adults Eat, and What Should They Avoid?

Food is an important part of caring for older adults’ health. As the body moves from middle age into retirement age, many changes occur, such as slower digestion, reduced muscle mass, and less effective control of blood sugar and blood pressure. Choosing suitable foods is therefore essential for supporting health, preventing disease, and sustainably improving quality of life.

This article explains which foods should be eaten, which should be avoided, and why eating meals on time is important. These are all key elements of caring for older adults correctly.

Foods to Eat

1. Easily Digested Protein
Protein plays an important role in maintaining muscle mass and repairing worn tissues, especially in older adults who are more likely to lose muscle. Choose easily digested protein sources such as:

Fish, such as mackerel, tilapia, and sea bass
Boiled or soft-boiled eggs
Tofu, soybeans, and other beans
Low-fat milk or unsweetened yoghurt

Protein intake should be approximately 1–1.2 grams per kilogram of body weight per day. For example, a person weighing 60 kilograms should receive around 60–72 grams of protein per day, distributed across every meal.

2. High-fibre Vegetables and Fruit
Fibre supports bowel movements, blood-sugar control, and lower blood lipids. Leafy green vegetables, pumpkin, carrots, apples, guava, and bananas are all good sources of dietary fibre and should be eaten regularly with every meal.

3. Whole Grains
Brown rice, Riceberry rice, oats, and other unrefined grains provide energy gradually, reduce fluctuations in blood-sugar levels, and also provide additional fibre.

Foods to Avoid: Reduce Disease and Improve Quality of Life

1. Fatty and Fried Foods
High-fat foods, especially those containing trans fats and saturated fats, such as fried pork belly, fried chicken, and French fries, can increase blood lipids and the risk of cardiovascular disease.

2. High-sugar Foods
Desserts, soft drinks, sweet milk tea, and other sugary foods cause blood-sugar levels to rise quickly, increasing the risk of diabetes and excess body weight.

3. High-sodium Foods
Processed foods such as sausages, meatballs, and instant noodles, together with strongly flavoured seasonings such as fish sauce, soy sauce, and monosodium glutamate, may cause high blood pressure and fluid retention when consumed in large amounts.

Drink Enough Clean Water

Clean water is essential for the body’s processes. It helps balance circulation and digestion and regulates body temperature. Older adults should drink approximately 1.5–2 litres, or 6–8 glasses, per day, divided throughout the day rather than waiting until they feel thirsty.

Insufficient water intake may cause constipation, dizziness, heatstroke, or low blood pressure, especially in older adults whose sense of thirst has declined.

Eat Meals on Time Because Timing Affects Medication and Health

Older adults often take regular medications, such as blood-pressure or diabetes medicines. Eating at irregular times may cause:

Medication to take effect at a time that does not match the body’s needs
Fluctuating blood-sugar levels
Faintness, dizziness, or fatigue

A clear meal schedule should be arranged, such as breakfast at 7:00–8:00 a.m., lunch at 12:00 noon, and dinner before 6:00 p.m. Small snacks between meals, such as a banana, apple, or unsweetened crispy grains, may help prevent blood sugar from dropping.

Precautions for People with Chronic Conditions

Older adults with chronic conditions such as diabetes, high blood pressure, heart disease, or kidney disease should seek advice from a doctor or dietitian before changing their menu, for example:

Control sodium when high blood pressure is present
Limit protein and potassium when kidney disease is present
Control sugar when diabetes is present

Choosing foods that suit each condition helps improve overall health and reduce long-term complications.

Suitable nutrition for older adults does not have to be complicated. Choosing food according to sound principles, focusing on high-quality protein and plant fibre, avoiding excessive fat and sugar, drinking enough water, and eating on time can help strengthen the body, reduce disease risk, and support a good quality of life every day.
