How Changes in Taste and Smell Affect Older Persons
As people age, changes in taste and smell can make meals seem less appealing. That can affect appetite, enjoyment, and food safety at home. Recognising these changes early can help older persons keep meals nourishing, enjoyable, and easier to manage.
Why Do Taste and Smell Change as You Age?
Human beings are born with thousands of taste buds. They detect sweet, salty, sour, bitter, and savoury (umami) flavours. The sense of smell contributes greatly to how we perceive taste because aroma and taste work together to tell the difference between foods. Changes in taste and smell often become more noticeable with age.
How Taste Buds Change With Age
The number of taste buds decreases, and remaining taste receptors may not respond as strongly, making it harder to enjoy meals that were once favourites.
With a declining sense of smell, the aroma that once made a warm bowl of soup inviting may not register in the same way. This can lead to less interest in fruits, vegetables, and nutrient-rich dishes.
To counteract these changes, it's common for older persons to experience sweet and salty cravings. To compound this, dry mouth, often caused by reduced saliva production, can also affect the taste of food and make it more difficult to swallow.
Other Causes of Taste and Smell Loss
Certain medications, including blood pressure medications, antihistamines, and antibiotics, can also affect taste and smell.
Nasal and sinus problems, such as sinusitis or congestion, may also interfere with smell, as can illnesses such as COVID-19. If medication could be part of the issue, it may help to review how to take medicine safely at home with a GP or pharmacist.
How Do These Changes Impact Appetite and Nutrition?
When older persons experience a diminished sense of taste and smell, their appetite may decline.
Meals that were once appealing may no longer taste or smell as good. This reduction in sensory enjoyment can have several important consequences:
Reduced nutrient intake - Individuals may struggle to consume enough fruits, vegetables, lean proteins, and other nutrient-rich foods.
Less enjoyment in eating - With flavours no longer as distinct, eating may become less pleasurable, turning a once-enjoyable experience into a routine task.
Decreased interest in key foods - Core dietary staples, including leafy greens or whole grains, may lose their appeal, leading to imbalanced meals.
Lower overall caloric consumption - Reduced interest in food can cause a drop in total calories eaten each day, affecting strength and energy levels.
Long-term health effects - Consistent nutrient shortfalls and diminished mealtime satisfaction can eventually influence overall wellbeing, making it harder to maintain good health and resilience.
How Can Older Persons Adapt to These Changes?
There are several steps older persons can take to improve their dining experience:
Enhance Flavour with Seasonings and Herbs
Adding fresh herbs, mild spices, or aromatic ingredients to dishes can help compensate for lost taste.
For example, seasoning vegetables with thyme or basil, or marinating lean meats in light sauces, can boost flavour without relying on excessive salt or sugar. A squeeze of lemon or lime juice, a splash of vinegar, or a pinch of black pepper can also brighten dishes and make flavours more noticeable.
Comfort Keepers provides guidance on personal care and meal preparation to help keep meals both enjoyable and nutritious.
Focus on Food Textures and Colours
Since taste buds may not function as well, exploring appealing textures and colourful produce can make meals more interesting. Crunchy vegetables, creamy soups, or a plate arranged with bright fruits can engage other senses like sight and touch, making it easier to enjoy eating.
Address Dry Mouth Concerns
If dry mouth makes swallowing difficult, discussing options with a pharmacist or GP can help identify products such as artificial saliva sprays or lozenges. Ensuring a balanced fluid intake and choosing foods that are easier to swallow, like mashed potatoes or soups, can also help.
Food Safety With a Reduced Sense of Smell
With a reduced sense of smell, spoiled or rancid food can be harder to identify. Marking purchase dates on containers, checking use-by dates, and storing food carefully can reduce that risk.
If shopping is becoming harder, shopping support for older persons can help keep fresh ingredients topped up. It also helps to make sure smoke alarms and carbon monoxide alarms are working properly as part of general home safety.
Our carers can assist with food handling, meal preparation, and routines that support safety at home.
Maintain Social Engagement Around Meals
Eating with family, friends, or with support through companionship care can create a more enjoyable dining atmosphere. Discussing meal choices, sharing recipes, or cooking together encourages older persons to find delight in the eating experience despite taste changes.
When to Seek Professional Advice
If changes in taste and smell are sudden, severe, or linked with other symptoms, it is worth speaking with a GP. A dentist may also help identify oral health issues that are affecting taste or making eating uncomfortable.
