Eating Well as You Get Older: Practical Tips for Older Adults
Practical tips for older adults on protein and fiber from food, drinking enough, changes in appetite and taste, food safety, and cooking for one or two.
Key takeaways
- Some older adults need fewer calories but still need as much or more of nutrients such as protein, vitamin B12, vitamin D and calcium, according to the 2025–2030 Dietary Guidelines; ask your doctor what that means for you.
- Drink fluids through the day even if you are not thirsty: MedlinePlus says some people lose their sense of thirst as they age.
- Older adults are at higher risk from foodborne illness; the FDA lists foods to avoid, and leftovers keep 3 to 4 days in the refrigerator.
- If food tastes bland, the NIA suggests herbs, spices or lemon juice, and a doctor can check whether a medicine is changing taste or appetite.
Eating well later in life comes down to a few repeatable habits: get enough protein and fiber from real food, keep fluids coming through the day, and cook in a way that suits your kitchen and your appetite. This guide pulls together what federal sources say and turns it into steps you can use this week.
What changes and what stays the same
The 2025–2030 Dietary Guidelines have a short section on older adults. It says 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. To meet those needs, it says to prioritize nutrient-dense foods such as dairy, meats, seafood, eggs, legumes and whole plant foods (vegetables and fruits, whole grains, nuts and seeds).
In other words, the plate stays much the same, but there is less room for foods that add calories without much else. The National Institute on Aging (NIA) describes the same idea: choose a variety of nutrient-dense foods across and within the food groups, and for a visual of how that looks at each meal, see our balanced plate guide.
Protein and fiber from food
The NIA explains that protein is used to build and repair tissues, and says older adults should try to eat a variety of nutrient-dense proteins. Besides meat and poultry, it notes you can get protein from seafood, eggs, beans, nuts, seeds and soy products. To get enough protein through the day and maintain muscle, it suggests adding seafood, dairy or fortified soy products along with beans, peas and lentils to your meals.
For a general target, the Dietary Guidelines give a protein serving goal of 1.2 to 1.6 grams per kilogram of body weight per day, adjusting as needed based on your individual caloric requirements. If you have kidney disease or another condition, ask your doctor before changing how much protein you eat.
Fiber comes from plants. The NIA notes that fiber is found in vegetables, beans and peas, and that fruit eaten with the skin on has more fiber. For grains, the 2025–2030 Dietary Guidelines say to prioritize fiber-rich whole grains and to significantly reduce highly processed, refined carbohydrates such as white bread.
| Goal | Foods the sources name | Easy way to use them |
|---|---|---|
| Protein | Seafood, dairy, eggs, beans, peas, lentils, nuts, seeds, soy products | Eggs with toast, lentil soup, canned beans over rice, yogurt |
| Fiber | Vegetables, beans, peas, fruit with the skin on, whole grains | Oatmeal with a washed apple, bean chili, whole-grain bread |
| Calcium and vitamin D | Dairy, and fortified soy milk and yogurt | Milk or yogurt with breakfast, fortified soy beverage if you avoid dairy |
If you avoid dairy, the NIA says to talk to your health care provider about how to get enough calcium and vitamin D.
Drink fluids even when you are not thirsty
Thirst can be a poor guide with age. MedlinePlus lists older adults among those more likely to develop dehydration and says some people lose their sense of thirst as they age. Its listed symptoms in adults include dry mouth, dark-colored urine, feeling tired and dizziness.
MedlinePlus advises you to drink enough water every day and to ask your health care provider how much you should be drinking, because each person’s needs differ. The NIA also advises you to drink plenty of water throughout the day and to avoid sugary drinks. Our hydration basics guide goes into more detail.
When appetite or taste changes
Food can lose its appeal for many reasons. The NIA’s roadblocks page covers the most common ones, and each has a practical fix.
| What you notice | What the NIA suggests |
|---|---|
| Food tastes bland | Try adding fresh herbs, spices or lemon juice, and ask about food-drug interactions when you get a new prescription |
| Not hungry | Talk with your doctor about side effects, try to be more active, and season food with lemon juice, vinegar or herbs rather than extra salt |
| Trouble chewing | See your dentist, and if you wear dentures have the fit checked |
| Food seems to get stuck | Talk to your doctor about what may be causing swallowing problems |
| Too sad to eat | If low feelings last a few weeks or months, talk with your doctor |
The NIA also suggests varying the shape, color and texture of foods and steaming vegetables for a shorter time so they keep some crunch.
Food safety matters more with age
The FDA explains that as people age, their immune system and other organs become sluggish at recognizing and ridding the body of harmful bacteria. Higher-risk people are more likely to have a longer illness, be hospitalized, or die, so careful handling matters.
If you are at greater risk, the FDA advises avoiding foods including raw or undercooked meat or poultry, raw sprouts, raw or undercooked eggs and unpasteurized milk. It adds that hot dogs, luncheon meats and other deli-style meats should be reheated until steaming hot before you eat them.
For leftovers, USDA FSIS says to refrigerate them within 2 hours and to reheat them to 165°F as measured with a food thermometer.
Shopping and cooking at your own pace
The NIA’s tips are practical: plan in advance and make a shopping list to help stick to a budget, and look for pre-cut fruits and vegetables if slicing and chopping are a challenge. Our healthy grocery list on a budget guide has more on stretching your food dollars.
Cooking for one
Cook once and eat twice. Make a pot of soup, chili or a casserole, then divide it into single portions. FSIS says leftovers keep 3 to 4 days in the refrigerator or 3 to 4 months in the freezer, so freeze what you will not eat in time.
Canned beans, eggs, frozen vegetables and plain yogurt are all quick protein and fiber helpers. Our meal planning for one guide has a week of ideas.
Cooking for two
Scale a recipe for two, then use the extra as lunch the next day. Split the work: one person washes and chops, the other cooks. The NIA suggests that if you are tired of cooking, you try cooking with a friend to make a meal you can enjoy together.
Getting help with meals
You do not have to do it all yourself. The NIA suggests potluck meals where everyone brings one part, food delivery services, or meals at a nearby senior center, community center or religious facility. The same NIA page points to the Eldercare Locator to search for centers in your area.
If an illness such as arthritis makes cooking hard, the NIA says your doctor might recommend an occupational therapist, who might suggest rearranging things in your kitchen. It adds that special utensils and plates might make mealtimes easier.

Frequently asked questions
Do older adults need to eat less?
Not necessarily everything. The Dietary Guidelines say 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. Your doctor or a registered dietitian can tell you what fits your age, health and activity.
Why am I not feeling thirsty?
MedlinePlus says some people lose their sense of thirst as they age, so they don't drink enough fluids. It advises drinking enough water every day and asking your health care provider how much you should drink, since each person's needs can be different.
Which foods should I avoid for food safety?
The FDA advises people at greater risk of foodborne illness to avoid raw or undercooked meat, poultry and eggs, raw sprouts, unpasteurized milk and juices with a warning label, and deli meats unless reheated until steaming hot. Its page has the full list.
How long do leftovers last when I cook for one?
USDA FSIS says leftovers can be kept in the refrigerator for 3 to 4 days or frozen for 3 to 4 months, and should be refrigerated within 2 hours of cooking. Freezing single portions makes it easy to eat them in time.
Why does food taste different now?
The NIA says growing older, dental problems and medication side effects can change your sense of taste, smell or both. Fresh herbs, spices or lemon juice may help, and your doctor can review whether a medicine is involved.
