How Guidelines Change Benchmarks for Older Adults

Age can affect population benchmarks for nutrition and physical activity. Guidelines for older adults place particular emphasis on balance and strength exercises, adequate intake of protein, calcium, iron, and vitamin D. At the same time, different institutions may use their own approaches and age thresholds, so the values provided should be read as benchmarks, not as a personal prescription.

What the evidence says

WHO recommends that people aged 65 and older add varied balance and strength exercises on 3 or more days a week. This is a distinct emphasis in recommendations for older age: the focus is not only on general physical activity, but also on practices that engage strength and balance. The specific choice of exercises depends on how a person feels, their previous experience, and the safety of performing them.

According to National Health and Medical Research Council Australia and Ministry of Health New Zealand, after age 70, the protein benchmark increases to 81 g per day for men and 57 g per day for women. In the same guidelines, after age 70, adequate vitamin D intake increases to 15 mcg per day. National Institutes of Health Office of Dietary Supplements in the United States gives a recommended vitamin D intake of 20 mcg, or 800 IU, per day for people over 70. This illustrates that benchmarks from different institutions may differ.

Calcium also has age-related features. According to National Institutes of Health Office of Dietary Supplements, after age 70, the recommended calcium intake is 1200 mg per day for men and women, while after age 50, the upper tolerable intake level decreases to 2000 mg per day. National Health and Medical Research Council Australia and Ministry of Health New Zealand specify 1300 mg of calcium per day for men aged 71 and older and women aged 51 and older. Population benchmarks are not personal prescriptions.

What this looks like in practice

It is useful to apply such data as a list of topics for planning diet and activity, rather than as a set of mandatory targets. The following benchmarks are worth noting:

• WHO advises people aged 65 and older to perform balance and strength exercises on 3 or more days a week.
• According to National Health and Medical Research Council Australia and Ministry of Health New Zealand, after age 70, the protein benchmark is 81 g per day for men and 57 g per day for women.
• National Institutes of Health Office of Dietary Supplements gives 1200 mg of calcium per day after age 70 and an upper tolerable intake level of 2000 mg per day after age 50.
• According to NHS, women aged 50 and older have the same iron requirement as men — 8.7 mg per day. National Institutes of Health Office of Dietary Supplements and National Health and Medical Research Council Australia and Ministry of Health New Zealand give an iron intake of 8 mg per day for women over 50.
• According to Міністерство охорони здоров'я України, the daily carbohydrate benchmark for women aged 60–74 is 270 g, and for women aged 75 and older — 240 g. For men, these benchmarks are 300 g at ages 60–74 and 270 g at age 75 and older.
• According to Міністерство охорони здоров'я України, the daily energy benchmark for women aged 60–74 is 1800 kcal, and for women aged 75 and older — 1600 kcal.

What to keep in mind

Benchmarks depend not only on age but also on the source of the recommendations. This is evident in the examples of calcium, iron, and vitamin D: different institutions provide different values or use different terms, such as “recommended intake” and “adequate intake.” Therefore, it is not advisable to mechanically combine all the figures from different guidelines into one personal plan.

The energy and carbohydrate data provided by Міністерство охорони здоров'я України apply to specific age groups and sexes. They do not describe every individual circumstance. If a person has dietary considerations, mobility limitations, or other factors that affect their diet or the safety of exercise, it is appropriate to discuss them with a professional.

In brief

• After age 65, WHO advises adding balance and strength exercises on 3 or more days a week.
• After age 70, some guidelines increase the benchmarks for protein and vitamin D.
• Age-related benchmarks for calcium and iron may change, and may differ between institutions.
• Ukrainian benchmarks for energy and carbohydrates vary by age and sex.
• Population benchmarks are not personal prescriptions.
