What "eating well" actually means at 70, 80, 90
The eating rules you learned at 40 weren’t designed for 70. A short read on what changes, what stays, and why the difference matters.
Most older Australians grew up with a clear set of nutrition rules. Smaller portions are better. Less fat is better. Avoid the snacks. Don’t eat too much late at night. Those rules made sense for the body of a 40- or 50-year-old, and most of us absorbed them deeply enough that they still drive what’s on the plate decades later.
The trouble is, the body of a 70-year-old or an 80-year-old works differently — and a few of those rules quietly stop being good advice.
One of the biggest surprises of healthy ageing is that your body often needs more protein and nutrition support, not less.
What changes
The headline change is that the body needs more nutrition per kilo, not less, as it ages. The systems that turn food into energy and into muscle become slightly less efficient. The appetite drops, naturally. The thirst signal softens.
The result is that a person can be eating a "sensible" diet — small portions, low fat, no snacks — and quietly not getting enough of what their body now needs.
Three specifics worth knowing
- Protein needs go up, not down. Australian Nutrient Reference Values: a healthy woman aged 19-70 needs about 0.75 g of protein per kg of body weight per day. After 70, that goes up to 0.94 g/kg. For men: 0.84 g/kg under 70, 1.07 g/kg over 70. The contemporary clinical guidance pushes higher still — 1.0 to 1.2 g/kg per day for healthy older adults, more after illness or surgery.
- Energy needs drop, but smaller meals can still hit the protein and nutrient targets if they’re chosen well. The "less" needs to be the right kind of less.
- Snacks become more important, not less. A small snack between meals — a piece of cheese, a handful of nuts, a small tub of yoghurt — is one of the easier ways to hit protein and energy targets when appetite is quieter.
What stays
A few things didn’t change.
- Real food is still the foundation. Vegetables, lean protein, whole grains, dairy. The Mediterranean-style eating pattern that’s been good advice for forty years is still good advice.
- Hydration matters. Slightly more than the average person realises.
- Variety helps. Eating the same five meals every week works for staying alive; it doesn’t work as well for staying strong.
The simplest shift
If there’s one practical change worth making, it’s this: at each meal, ask "is there protein here?"
If the answer is no — toast and tea, soup alone, a piece of fruit — add something. An egg with the toast. Cheese with the soup. A small piece of meat or fish with dinner. A spoonful of yoghurt with the fruit.
That single habit — protein at every meal — does more for strength and recovery after 70 than almost any other dietary change.
Before asking whether you're eating less, ask whether you're getting enough protein at each meal.
Three things to try this week
- Pick one meal you regularly have low on protein. Add one small protein to it. Make it a habit.
- Have a small snack between meals if your appetite is quiet. A handful of nuts, a small piece of cheese, a tub of yoghurt.
- If you’ve been told to "eat less" or "watch your weight" in the last few years, talk to your GP or a dietitian about whether that advice still fits your current health and strength.
Staying strong at home
The eating rules that worked at 40 were good for the body you had at 40.
The body at 70 wants something a bit different — more protein, more attention to snacks, more focus on strength than on weight.
The shift doesn’t have to be dramatic. It does have to happen.
