Nutrition for Over-55s: What Actually Works (According to the Evidence)
Food should support your life, not rule it. After years of training people in their 50s, 60s and beyond, that's the one piece of nutrition advice I'd keep if I had to bin all the rest. Too much of the nutrition advice aimed at people over 55 in the UK makes eating sound like a second job. Eat well and you'll have more energy for the things you love, more strength for carrying the shopping and the grandchildren, and you'll feel like yourself on a good day, most days. None of it requires a diet with a name.
You won't find better eating in a fad diet
If you want to eat better, you won't find it in a fad diet. You'll find it in your own kitchen, in food you already like, eaten in amounts that match what you do all day. There are no bad foods, just bad quantities. A slice of cake at your grandson's birthday is a slice of cake. Fourteen slices a week is a pattern worth changing.
Read the labels too, because plenty of food sold as “good” can be as bad as the regular version: high calorie, highly processed, high sugar. Fad diets drive this. The low-fat wave was the classic example. Manufacturers took the fat out, and to keep the taste they put sugar in, so a yoghurt that looked virtuous on the shelf often carried more sugar than the pudding it replaced. When a label shouts about what's been removed, check what's been added.
Protein deserves your attention
If I could get every member to change one thing, it'd be protein. Muscle responds to food as well as effort, and from your 50s onwards, you need more protein than you did at 30, not less. Most people over 55 eat less than they need.
The research gives a specific target. Phillips, Chevalier and Leidy (2016) put the useful range for older adults at 1.2 to 1.6 grams of protein per kilogram of body weight a day. For someone weighing 70kg, that's roughly 84 to 112 grams. The second half of the advice matters as much as the number: spread it across your meals rather than loading it all into dinner, because your body uses a steady supply better than one big delivery.
You don't need powders to get there. Eggs at breakfast, fish or chicken at lunch, beans or lentils in the evening, Greek yoghurt as a pudding or a snack. And if you're doing the strength classes on the Jim's Gym timetable, protein is what turns that work into results. A 2024 review by Whaikid and Piaseu found that protein combined with resistance exercise improved muscle mass and strength in older adults who'd already lost muscle. Food and effort work as a pair.
Feed your bones
Calcium and vitamin D keep bones strong, and recent reviews (Cianferotti and colleagues, 2024; Boyanov and Boyanova, 2024) support both for bone health and fracture risk in older adults. My rule is food first. Calcium comes readily from milk, cheese, yoghurt, tinned sardines eaten bones and all, and greens like kale. Vitamin D comes mostly from daylight on your skin, with oily fish, eggs and fortified cereals helping you through a British winter.
You won't find supplement doses in this post, because the right amount depends on you. If you're thinking about supplements, ask your GP or a registered dietitian first. Ten minutes of their time beats a guess in the vitamin aisle.
Patterns beat superfoods
No single food will transform your health, whatever the marketing says. Patterns will. The best-studied pattern is Mediterranean-style eating: vegetables and fruit at most meals, plus beans, nuts, whole grains, olive oil and regular fish, with meat and sweets taking a smaller role. Variety does the rest.
In older adults, this way of eating is linked with living longer and having fewer heart problems (Furbatto and colleagues, 2024), and with better mood and quality of life (Godos and colleagues, 2023). Diets built around plants and fibre are also linked with better measurable risk factors such as cholesterol and inflammation (Pandey and colleagues, 2024). None of that came from a superfood. It came from ordinary shopping done week after week.
Drink before you feel thirsty
Thirst gets quieter with age. Studies of older adults show the signal weakens (Li, Xiao and Zhang, 2023) and that drinking too little is common in this age group (Parkinson and colleagues, 2023). So don't wait for thirst. Get ahead of it.
My tip: pour a glass of water every time you put the kettle on. If the kettle goes on four or five times a day, that's four or five glasses without any counting. Pale yellow urine tells you you've got it about right.
Make it yours
Nutrition is personal. What works is whatever fits your taste, your budget and your week, which is exactly why it should support you rather than rule you.

FAQ
How much protein do I need after 55?
Research suggests older adults benefit from 1.2 to 1.6 grams of protein per kilogram of body weight a day, roughly 84 to 112 grams for someone weighing 70kg. Just as important, spread it across your meals rather than saving it all for dinner, as your body uses a steady supply better.
Do I need protein powders or supplements?
Not usually. Most people can hit their target with everyday food: eggs at breakfast, fish or chicken at lunch, beans or lentils in the evening, and Greek yoghurt as a snack. Powders are convenient, not essential. Whole foods bring other nutrients a scoop of powder simply doesn't.
Is a Mediterranean diet actually better for older adults?
The evidence is strong. Mediterranean-style eating, plenty of vegetables, beans, nuts, whole grains, olive oil and fish, is linked with living longer, fewer heart problems and better mood in older adults. It works as a pattern you keep up week after week, not a short-term diet with a finish line.
How much water should I drink as I get older?
Thirst weakens with age, so don't wait until you feel it. A simple habit helps: pour a glass of water every time you put the kettle on. Little and often through the day beats trying to catch up in one go, and keeps energy and concentration steadier.
Should I take calcium or vitamin D supplements for my bones?
Food first is the sensible rule. Calcium comes from dairy, tinned sardines and greens; vitamin D mostly from daylight, plus oily fish and eggs. Supplement doses depend on your own situation, so ask your GP or a registered dietitian before starting rather than guessing in the vitamin aisle.
