Healthy Eating in Older Adults 1


Deciding what we mean by ‘older people’ is a little arbitrary. The World Health Organization classifies people aged between 45 and 59 as ‘middle age’, 60 to 74 as ‘elderly’ and over 75 as ‘old’.

But the nutritional needs of older adults are difficult to neatly categorise into absolute age groups. Dietary needs depend on current health, and while many older people are fit and active, some others who are younger may be frail and require additional care.

Nutrition for generally fit and healthy older adults

Fat

Advice to restrict fat intake, particularly cutting saturated fat to improve heart health, remains true for older people who are fit and well. Above the age of 75, fat restriction is less likely to be beneficial, and isn’t appropriate if the person is frail, has suffered weight loss or has a very small appetite. In fact, in these situations additional fat may be used to increase the calories in meals and snacks to aid weight gain.

Fibre

Older people can suffer from constipation and bowel problems mainly due to a reduced gut motility and inactivity. To relieve this, try eating high-fibre cereal foods, fruit and vegetables. Raw bran and excessive amounts of very high-fibre foods are not the answer, though; they’re too bulky and may interfere with the absorption of certain nutrients. To help the gut work properly, it’s also important to drink plenty of fluid, approximately eight medium glasses a day.

Fluid

Dehydration can make people feel drowsy or confused, it’s important to drink, even if this means extra trips to the toilet. The risk of dehydration can be higher in older people because their kidneys don’t function as efficiently as those of younger people. Older people are also not as sensitive to the feeling of thirst. Fluid intake doesn’t just mean water – it can also include such drinks as tea, coffee, fruit juice and squash.

Sugar

Generally fit and healthy older people should limit foods and drinks that are rich in sugar, as it can impair dental health and contribute to weight gain when energy intake is too high. But for people who have a poor appetite, or who have lost weight, sugar-rich foods can be a useful source of calories.

Iron

Anaemia is common in older adults. Poor absorption of iron, due to changes in the gastrointestinal tract, blood loss and the use of certain drugs – together with a poor dietary intake – may be causal factors. Make sure your iron intake is sufficient by eating red meat and foods from non-meat sources (such as fortified cereals, dried fruit, pulses and green leafy vegetables) every day. Absorption of iron from a meal containing non-meat sources is maximised by consuming foods rich in vitamin C at the same time (such as a glass of fruit juice, fresh fruit or vegetables).

Zinc

Zinc is needed for a healthy immune system and to support the healing of wounds including pressure ulcers. Rich sources include meat, pulses, wholemeal bread and shellfish.

Calcium and vitamin D

Adequate intake of calcium and vitamin D may help to slow the rate of calcium loss from bones, which starts at the age of 30 and accelerates considerably in later years. Calcium-rich foods (milk and dairy foods) should be eaten every day.

Vitamin D comes mostly from exposing skin to sunlight, although some foods such as oily fish and fortified spreads and breakfast cereals contain vitamin D. As you get older it’s advisable to take a vitamin D supplement, as your body isn’t able to get enough from the diet and British weather alone.

Vitamin C

Older people may have low vitamin C intakes if not consuming enough fruit and vegetables. This may be because crisp fruit and vegetables are often avoided if their teeth are in poor condition or if they have badly fitting dentures.

Regular check-ups with the dentist can help to ensure that teeth remain healthy, enabling older people to continue to enjoy a variety of foods that will help maintain overall health.

Foods to choose

To meet your nutritional needs, aim to eat a varied diet including regular meals and snacks, and drink enough fluid.

Sometimes older people can no longer eat as much food at a single sitting, so include more nutritious snacks in between meals to boost nutrient intake.
