Dementia affects memory, thinking, and the ability to perform everyday activities. As a progressive condition, it can also impact a person’s nutritional intake and overall health. Individuals with dementia may experience changes in mental, physiological, and cognitive functions that can affect their appetite, eating habits, and ability to prepare or consume meals. Understanding these challenges allows caregivers to better support proper nutrition, hydration, and mealtime routines, helping to maintain the individual’s well-being and quality of life.
Common nutritional issues in dementia
Undernutrition and weight issues: Changes in taste and smell can make food seem less appealing, which may lead to decreased appetite, weight loss, and inadequate nutrient intake. Some individuals may experience behavioural changes such as agitation during mealtimes, along with a reduced interest in food. Some people may also forget to eat or have difficulty recognising food. On the other hand, certain types of dementia, such as frontotemporal dementia, may cause the opposite pattern, where individuals overeat and develop strong cravings for sweet foods or carbohydrates. These changes can make maintaining proper nutrition challenging and may require caregivers to provide additional support and monitoring.
Increase the risk of health problems: Many people with dementia also experience mobility difficulties and require assistance with toileting and personal hygiene, which further raises the risk of urinary tract infections. Muscle wasting is highly prevalent in this population, with many experiencing reduced strength, mobility, and functional independence, often worsened by insufficient protein intake. These combined health issues can also exacerbate confusion, mood changes and behavioral symptoms, making dementia more challenging to manage.
Dehydration and risk of falls: Compared to typical age-related dehydration, individuals with dementia are vulnerable to potentially dangerous conditions because their ability to sense thirst is often reduced, and cognitive impairments make it harder for them to remember to drink water. Dehydration can cause dizziness and weakness, increasing the risk of falls. Caregivers should watch for signs of dehydration in elderly loved ones, including dry mouth, decreased urination (such as going eight or more hours without urinating) and dark yellow urine.
Healthy eating for individuals with dementia
As cognitive function declines, maintaining proper nutrition becomes increasingly challenging, yet it is critically important. Throughout the illness, nutrition remains a vital component to maintaining both physical and psychological wellbeing. Good nutrition can help people with dementia to keep their energy up, support their brain health, and prevent problems like weight loss or getting sick more easily.
Incorporation of Mediterranean diet
A Mediterranean diet, rich in natural foods and high in antioxidants, is thought to be beneficial for individuals with dementia. This diet emphasizes fruits, vegetables, whole grains, legumes, nuts, and olive oil, along with moderate consumption of fish and poultry and limited red meat and processed foods. The high content of antioxidants, healthy fats, and fiber supports brain health, cardiovascular function, and overall nutrition, which may help slow cognitive decline and reduce the risk of dementia-related complications.
Practical ways to apply a Mediterranean diet
– Add more and different vegetables to the menu from leafy green to root vegetables. Add an extra serving of vegetables to both lunch and dinner, aiming for three to four servings a day.
– Replace at least one meal per week with a legume-based dish (chickpeas, lentils, beans) or a whole-grain dish to increase fiber and protein intake.
– Swap unhealthy fats for extra virgin olive oil in cooking and dressings.
– Eat oily fish (salmon, tuna) around twice a week.
Mediterranean-inspired meal ideas:
Whole grain toast with avocado, feta, tomato, or baked beans, or poached eggs.
Muesli with natural yogurt, fruits, and nuts.
Quinoa bowl with avocado, grilled chicken, and salad greens.
Soups with lots of vegetables, lentils, beans, and tomatoes.
Meal planning tips for easier eating
– Instead of unmoistened toast, soften it first in milk.
– Instead of chewy, high-fat cheese cubes for a snack, offer low-fat cottage cheese.
– Instead of a soup with large chunks of food, serve a low-sodium broth soup with a smooth texture.
– Instead of crispy vegetables with dinner, serve vegetables that have been steamed or boiled until soft.
