Eating well: the complete, no-fad guide

Most food advice aimed at people over 50 is really weight-loss advice in a cardigan. This guide is not that. It is about eating in a way that keeps you strong, steady on your feet, clear-headed and enjoying your dinner — for the next thirty years, not the next thirty days.

Nothing here is medical or dietary advice. If you have a health condition, take regular medication or have been told to follow a particular diet, check with your GP (family doctor) or a registered dietitian before changing what you eat.

What actually changes after 50

A few things shift, mostly quietly.

Appetite. Many people find they simply want less. The US National Library of Medicine puts it plainly: “You may need fewer calories, but you still need to get enough nutrients. Some older adults need more protein.” That is the whole puzzle in two sentences — a smaller plate that has to work harder.

Muscle. Nearly half the protein in your body is in your muscle, and muscle mass decreases with age. The US guidance on protein for older adults notes that this loss — sarcopenia — “may lead to frailty, disability, loss of independence”. Food and strength work are the two levers you have. (For the exercise half, see our Move guides.)

Bone. Calcium and vitamin D do the structural work. Needs don’t fall with age; if anything the US guidelines raise the targets after 70.

Thirst. The British Dietetic Association says older people “may not recognise the feeling of thirst in the same way”. You can be short of fluid and not feel it.

Taste and smell. Food can seem blander. MedlinePlus suggests adding “colour and texture to make your food more interesting” rather than reaching for the salt.

None of this is a problem if you know it is coming. It just means eating well after 50 is a bit more deliberate than it was at 30.

The shape of a good day: Eatwell and the US guidelines

You don’t need a special “over-50s diet”. The NHS Eatwell Guide and the US Dietary Guidelines describe the same basic plate.

The Eatwell Guide says fruit and vegetables and starchy foods (bread, rice, potatoes, pasta) should each make up “just over a third” of what you eat, with protein foods and dairy or alternatives as smaller sections and oils and spreads used sparingly. It asks for at least five portions of a variety of fruit and vegetables a day, two portions of fish a week (one oily, such as salmon, sardines or mackerel), and higher-fibre, wholegrain versions of starchy foods where you can.

The 2025–2030 US Dietary Guidelines say something worth pinning to the fridge: “Some older adults need fewer calories but still require equal or greater amounts of key nutrients such as protein, vitamin B12, vitamin D, and calcium.” Their advice is to lean on nutrient-dense foods — dairy, meat, seafood, eggs, beans and lentils, and whole plant foods.

So: half the plate plants and wholegrains, a proper portion of protein at every meal, dairy or a fortified alternative, and enough to drink. That is the whole framework.

Protein: the one to get right

If you change one thing, make it this.

The UK reference intake for adults, quoted by the British Nutrition Foundation, is 0.75g of protein per kilogram of body weight per day. The US guidance for older adults gives 0.8g/kg as the official allowance and notes that “emerging research” points to 1–1.2g/kg. The new US guidelines go further, suggesting 1.2–1.6g/kg for adults generally. The direction of travel is clear: more than the old minimum, especially if you are active.

Just as important is when. The US older-adults guidance says protein “should be spread out throughout the day with good protein sources at each meal” — and singles out breakfast as “a good opportunity” via eggs and Greek yoghurt. Toast and marmalade at eight, a sandwich at one and a big dinner at seven is the classic pattern that leaves the morning empty.

Our full article — Protein after 50: how much, when, and the easy ways to get it — has a table of everyday foods and the simplest breakfast fixes.

Fibre, calcium and vitamin D

Fibre. The NHS says adult fibre intake “should increase to 30g a day”, and that most adults manage only about 20g. The gap closes with unglamorous things: porridge, wholemeal bread, potatoes with skins on, beans, lentils, chickpeas, fruit, vegetables, nuts and seeds. It helps digestion, and the NHS links a higher intake with lower risk of heart disease, stroke, type 2 diabetes and bowel cancer.

Calcium. The NHS figure for adults is 700mg a day, from dairy, leafy greens such as kale, calcium-fortified soya drinks and bread, and fish eaten with the bones (sardines, pilchards). The US guidelines set higher daily goals for older adults — 1,200mg for women over 50 and for men over 70 — so if you are in the US, that is the number your doctor will be working from.

Vitamin D. Your body makes it from sunlight, and in the UK the sun is not strong enough between about October and early March. The NHS says “everyone should consider taking a daily vitamin D supplement during the autumn and winter”, at 10 micrograms a day, and that some people — those who are rarely outdoors, in a care home, or who have darker skin — should consider it all year. The NHS also gives an upper limit for adults of 100 micrograms a day. This is general information: talk to your GP or a pharmacist about what is right for you rather than picking a bottle off the shelf.

Drink: water, and alcohol

The Eatwell Guide recommends six to eight cups or glasses of fluid a day, and the BDA translates that into “at least 1,600ml (3 pints)” for women and “at least 2,000ml (3½ pints)” for men — more in hot weather. Tea, coffee, milk and soup all count. Pale yellow urine is the check.

On alcohol, the UK Chief Medical Officers’ guideline, as set out by the NHS, is not to drink more than 14 units a week on a regular basis, to spread that over three or more days, and to have several drink-free days each week. The NHS puts a pint of higher-strength (5.2%) beer at 3 units and a large 250ml glass of 12% wine at 3 units, so 14 units is somewhere under five pints, or about a bottle and a half of wine, across the whole week. The 2020–2025 US guidelines say two drinks or fewer a day for men and one or fewer for women, and warn of “greater fall and accident risk” for older adults; the 2025–2030 edition simply says “consume less alcohol for better overall health.”

Our article on thirst, hydration and alcohol after 50 goes into the practical side.

Cooking for one or two

Half the difficulty of eating well after 50 is not nutrition at all. It is that cooking a proper meal for one person, every night, feels like a lot of washing-up for not much reward.

The fix is to stop cooking one meal at a time. Age UK’s suggestion is the standard one: make “extra portions of meals and freezing them so you can have them later in the week”. Cook a big pot of something on Sunday, freeze it in single portions, and you have three dinners in the bank. Keep a small set of freezer and cupboard staples — frozen peas and spinach, tinned beans and fish, eggs, a good cheese — and a meal is never more than fifteen minutes away.

Cooking for one (or two) without the waste or the boredom lays this out properly, including the “component” approach that makes leftovers feel like a different meal.

Eating well on a budget

Good food does not have to be expensive. The cheapest sources of protein and fibre — eggs, tinned fish, dried or tinned pulses, oats, frozen vegetables, milk and yoghurt — are also among the best. The BDA and Age UK both say frozen, tinned and dried fruit and vegetables count towards your five a day, so there is no virtue in paying for fresh berries in January. Buy the wholegrain version of the things you already buy, and let the freezer take the strain of buying in bulk.

If you want all of this laid out week by week — shopping lists, batch-cook days, a protein target for each meal — our Eat Strong four-week kitchen planner does exactly that, for £7.

Why diets fail (and what to do instead)

Diets fail because they are designed to end. They ask you to eat less of everything for a while, which after 50 is precisely wrong: the guidance above is about eating more of certain things, not less. A restrictive diet on a body that already has a smaller appetite is a fast route to losing muscle rather than fat.

The alternative is boring and it works. Anchor every meal with protein. Fill the rest of the plate with plants and wholegrains. Drink before you are thirsty. Take vitamin D through the winter. Keep some alcohol-free days. Cook in batches so a good meal is always the easy option. Do that most days, and let the occasional cake be a cake.
