In Brief

• After 65, eating for your heart means balancing two goals at once: protecting your heart while also protecting muscle, function, and independence.
• Functional status—robust, pre-frail, or frail—not age alone, shapes the right approach. For frail older adults, getting enough to eat can matter more than strict limits.
• Protein needs rise with age (about 1.0–1.2 g/kg of body weight per day, roughly 25–30 g per meal) to defend against muscle loss.
• Appetite loss, dental problems, medication interactions, and eating alone are common, treatable obstacles—not things to accept silently.
• Any change to a long-standing heart diet (sodium, fat, calories) should be made with your healthcare team, who can track your weight, symptoms, and labs.

Introduction

Cardiovascular disease remains the leading cause of death in adults over 65.[1] But after 65, eating for your heart is no longer only about lowering risk factors—it’s about balancing goals. The same restrictions that protect a 55-year-old’s arteries can, in a frail 85-year-old, accelerate muscle loss, weight loss, and the loss of independence. Good nutrition after 65 means protecting the heart while also protecting strength, function, and the ability to keep living on your own terms.

Malnutrition becomes more common with declining health and dependency—it is uncommon among independent, community-dwelling older adults but rises to roughly 30% in long-term and rehabilitation care.[2] Sarcopenia (age-related muscle loss) is also common and increases with age, as discussed below. In heart failure, poor nutritional status is associated with worse symptoms and higher readmission risk.[3] For older adults with poor appetite or declining function, aggressive dietary restriction can worsen nutritional status—and the consequences of malnutrition may matter more than small changes in cholesterol or blood pressure.

If finances, housing, or food access are your main barriers, pair this with Article 12: Heart-Healthy Eating When Life Is Hard.

Matching Nutrition to Your Functional Status

Your functional status—not just your age—is a major factor your healthcare team considers when making nutrition recommendations:

• Robust: Walks several blocks, independent in daily activities, stable weight → Standard cardiovascular nutrition (Mediterranean/DASH pattern) is typically appropriate.
• Pre-frail: Slower walking, some weakness, mild unintentional weight loss → Preserving muscle and function becomes a priority; protein and adequate calories matter more.
• Frail: Needs help with daily activities, recurrent falls, significant weight loss → Avoiding malnutrition is often the primary goal; restrictions may be adjusted.

This is for general orientation. Your healthcare team will determine what’s right for your specific situation based on your complete medical picture.

Regardless of your functional status: three priorities apply to many adults over 65—taking cardiovascular medications as prescribed, aiming to include a source of protein at most meals, and staying adequately hydrated within the limits your healthcare team recommends. The rest of this article helps you navigate the details.

How Aging Changes Nutrition Needs

The Aging Cardiovascular System

Arterial stiffening is a well-established feature of cardiovascular aging and an independent predictor of cardiovascular events.[4] As the large arteries lose elasticity, systolic blood pressure rises even when diastolic pressure stays controlled, and isolated systolic hypertension (systolic >140 with diastolic <90) becomes the dominant pattern after 65.

The heart muscle thickens in response to the increased workload. Diastolic dysfunction—impaired heart relaxation—contributes to heart failure with preserved ejection fraction (HFpEF), which makes up roughly half of heart failure cases and becomes more common with age.[5]

Blood pressure regulation also becomes less responsive. Reduced baroreceptor sensitivity increases the risk of orthostatic hypotension—blood pressure dropping when you stand, causing dizziness and falls.

Physiological Changes Affecting Nutrition

Protein and Muscle Preservation

If you’re over 65 and losing strength: make sure every meal includes a clear source of protein. This is especially critical if you’re pre-frail or frail.

Sarcopenia—the progressive loss of muscle mass and strength—is common in older adults and grows more prevalent with age, affecting a large share of the oldest old.[6] It substantially increases the risk of falls, fractures, disability, and death; hip fractures in particular carry considerable excess mortality in the first year, reported across studies in a wide range up to about a third.[7]

The cardiovascular connection: in heart failure, muscle wasting is common and independently predicts reduced exercise capacity and more advanced disease,[8] which in turn limits participation in cardiac rehabilitation.

Protein Requirements Increase With Age

The PROT-AGE study group recommends older adults consume 1.0–1.2 g/kg of body weight daily—higher than the 0.8 g/kg recommended for younger adults.[9] Why? “Anabolic resistance”—muscle becomes less responsive to protein with age, so you need more of it to achieve the same muscle-building effect.

• 120 lb (54 kg) → 54–65 g protein daily
• 150 lb (68 kg) → 68–82 g protein daily
• 180 lb (82 kg) → 82–98 g protein daily

Research suggests muscle responds better to an adequate amount of protein at each meal (about 25–30 g) than to small amounts spread thinly through the day.[10]

Protein Sources

When to Modify Protein Intake

Chronic kidney disease requires individualized guidance:

• CKD stages 1–3a: The targets above are usually appropriate.
• Stages 3b–5, not on dialysis: Protein may need to be closer to 0.8 g/kg—this must be individualized with a nephrologist and renal dietitian.
• On dialysis: Protein needs are higher (often 1.2–1.5 g/kg) because dialysis removes amino acids.

Appetite Challenges

If you’re not eating enough: shrink meal size, increase frequency, and make each bite higher in protein and calories.

“Anorexia of aging” is common and has multiple causes:

• Physiological: Increased satiety hormones, slower gastric emptying, altered taste and smell, early fullness.
• Medical: Medications affecting appetite, depression, dental problems, swallowing difficulty, constipation, uncontrolled pain.
• Social: Eating alone, bereavement, cognitive impairment, poverty, difficulty shopping or cooking.

Strategies to Improve Intake

These are general strategies—discuss with your healthcare team what’s appropriate for you.

• Prioritize nutrient- and calorie-dense foods when appetite is limited—this may include full-fat dairy, nuts and nut butters, avocados, olive oil, and eggs. For older adults with poor appetite and weight loss, your team may prioritize adequate intake over strict limits on fat or calories.
• Eat protein first when you’re most hungry.
• Smaller, more frequent meals. Five or six small meals instead of three large ones, if full meals feel overwhelming.
• Social eating whenever possible. Senior center meals, church community meals, Meals on Wheels, or inviting friends or family.
• Address treatable causes. Constipation worsens appetite. Depression is common, under-diagnosed, and treatable in older adults. Dental problems limit food choices.
• Enhance flavor. Use herbs and spices liberally; lemon juice and vinegar brighten food.

Oral Health and Eating

Poor dentition pushes people toward soft, ultra-processed foods and away from heart-protective foods like raw vegetables, nuts, and whole grain breads. Periodontal disease is associated with higher cardiovascular risk in observational studies.[11]

Heart-healthy foods for limited chewing:

• Proteins: Scrambled eggs, canned fish, ground turkey, mashed beans, cottage cheese, Greek yogurt, nut butters
• Whole grains: Oatmeal, soft whole wheat bread, well-cooked brown rice
• Vegetables: Well-cooked/steamed vegetables, soups, cooked greens, mashed sweet potato
• Fruits: Bananas, stewed fruits, applesauce, very ripe fresh fruits, avocado

Addressing dental problems can meaningfully improve nutritional intake.

When to Use Nutrition Supplements

Consider commercial nutrition shakes (Ensure, Boost, or generic equivalents) when there is:

• Unintentional weight loss despite efforts
• Eating less than half of meals regularly
• Recent hospitalization with deconditioning

Use them between meals, not as a meal replacement, and choose “Plus” or “High Protein” versions.

Red flags requiring medical attention:

• Unintentional weight loss >5% in 3 months or >10% in 6 months
• Unable to eat for more than 24 hours
• New swallowing difficulty

When Dietary Restrictions May Need to Change

If you’re losing weight on a strict heart diet: in some older adults, particularly those who are pre-frail or frail, clinicians may recommend adjusting dietary restrictions to prioritize adequate intake.

Standard cardiovascular advice emphasizes restriction: sodium below ~2,000 mg, saturated fat limits, calorie restriction for weight loss. This assumes decades of life expectancy, adequate baseline nutrition, and the ability to maintain intake despite restrictions.

Those assumptions may not hold for all older adults—particularly those over 75–80, or with frailty, poor appetite, or declining intake. In these situations, your healthcare team may determine that adequate nutrition takes priority over strict adherence to standard targets.

Any changes to dietary restrictions should only be made together with your healthcare team, who can monitor your weight, symptoms, and lab results. Do not change your diet based on this article alone.

Sodium

For some older adults without symptomatic heart failure, clinicians may relax sodium limits when stricter limits make food unpalatable and reduce overall intake. This decision depends on blood pressure control, symptoms, and overall health—and requires ongoing monitoring.

Critical exception: for people with heart failure and fluid retention, sodium restriction remains important for symptom control. Never change sodium intake without discussing it with your cardiologist.

Saturated Fat and Cholesterol

In some frail older adults with poor appetite, clinicians may allow full-fat dairy and eggs to help maintain adequate protein and calorie intake. This is an individualized decision weighing the immediate risks of malnutrition against long-term cardiovascular concerns.

Calorie Restriction for Weight Loss

Older adults should approach intentional weight loss cautiously and only under medical supervision, because calorie restriction often causes muscle loss. In many older adults with cardiovascular disease, preventing unintentional weight loss and preserving strength matters more than losing additional weight—especially when frailty or functional decline is present.

Having This Conversation

Ask your healthcare team: “Given my age, health status, and appetite, should I follow standard dietary restrictions, or might adjusting some of them help me maintain better nutrition overall?”

Common Conditions in Older Adults

The following is general education. Your specific nutrition plan should be developed with your healthcare team based on your individual conditions and medications.

Heart Failure with Preserved Ejection Fraction (HFpEF)

HFpEF makes up roughly half of heart failure cases and becomes more common with age, especially among older women.[5]

• Many people with HFpEF are advised to limit sodium to help control fluid retention and symptoms—your cardiology team will set a specific target if needed.
• Follow your cardiology team’s fluid instructions; monitor daily weights.
• Protein remains important—discuss targets with your team, as malnutrition worsens heart failure outcomes.
• If you also have chronic kidney disease, your cardiologist and nephrologist will help balance protein goals for muscle preservation with kidney function.

Atrial Fibrillation

Atrial fibrillation is common in older adults and becomes more frequent with advancing age.[12]

• If on warfarin: Maintain consistent vitamin K intake—eat similar amounts of leafy greens each week. Don’t suddenly increase or decrease them without telling your clinician.
• If on DOACs (Eliquis, Xarelto, Pradaxa): No vitamin K interaction. Eat leafy greens freely.
• Limit alcohol—even moderate alcohol increases the risk of AFib episodes.[13]

Hypertension

Many guidelines recommend systolic blood pressure below 130 mmHg for healthy, independent older adults, while allowing more lenient targets (often around <140 mmHg) for those who are frail, have multiple comorbidities, or have limited life expectancy.[14]

• The DASH diet can help lower blood pressure in older adults, but sodium reduction must be balanced against adequate intake.
• Critical: older adults on blood pressure medications are at high risk of orthostatic hypotension. Stay well-hydrated, rise slowly, and report dizziness.

Diabetes

Glycemic targets are usually more lenient with age: many experts aim for an A1c around <7.5% in healthy older adults, while <8.0–8.5% may be reasonable in frail older adults or those with multiple comorbidities.[15] Targets should be individualized with your diabetes care team.

Hypoglycemia is dangerous—it causes falls, confusion, and cardiovascular events. Don’t skip meals if you’re on diabetes medications.

Medications and Food

More than a third of older adults take five or more prescription medications, and this kind of polypharmacy has been rising.[16]

Common Interactions

• ACE inhibitors and ARBs (lisinopril, losartan): Can raise potassium. Avoid potassium supplements and salt substitutes unless approved.
• Diuretics: Loop diuretics deplete potassium and magnesium and increase fluid loss—maintain hydration.
• Statins: Grapefruit juice significantly increases blood levels of simvastatin, atorvastatin, and lovastatin—avoid grapefruit with these. Pravastatin, rosuvastatin, and fluvastatin do not interact with grapefruit.
• Beta-blockers: Can mask hypoglycemia symptoms in people with diabetes.
• Digoxin: High-fiber meals can reduce absorption—take it 1 hour before or 2 hours after high-fiber meals.

Annual Medication Review

Ask your doctor or pharmacist each year: “Can we review my medications and see if I still need all of them?” Deprescribing is appropriate and often beneficial in older adults.

Supplements

Discuss any supplements with your healthcare team before starting them. The following are commonly considered in older adults.

Vitamin B12. Reduced stomach acid makes B12 absorption from food less efficient with age. Deficiency is common and can cause fatigue, cognitive changes, and nerve problems. Your doctor can check B12 with a blood test; if it’s low, oral or injectable supplementation may be recommended.

Vitamin D. Many older adults have low vitamin D from reduced sun exposure, decreased skin synthesis, and limited dietary intake. Vitamin D matters for bone health and muscle function—both relevant to fall prevention. Blood testing can determine whether supplementation is appropriate.

Calcium. Calcium remains important for bone health, but supplementation is debated—some studies have raised questions about cardiovascular risk with calcium supplements, while others have not confirmed this. Most experts recommend getting calcium from food when possible (dairy, fortified foods, canned fish with bones, leafy greens). Discuss with your team whether supplementation is right for you, and don’t start it on your own.

A note on multivitamins. Evidence that routine multivitamin use prevents cardiovascular disease or improves outcomes in older adults is limited. If your diet is adequate and varied, a multivitamin may not be necessary. If your diet is restricted or your appetite is poor, a basic multivitamin may help fill gaps—but it’s not a substitute for adequate food.

Alcohol

Alcohol deserves specific attention in older adults because its risks rise with age:

• Fall risk: Even one drink can impair balance. Falls are a leading cause of injury and loss of independence in older adults.
• Medication interactions: Alcohol interacts with many common medications, including blood thinners, blood pressure and diabetes medications, and sedatives.
• Atrial fibrillation: Even moderate alcohol consumption increases the risk of AFib episodes.[13]
• Cognitive effects: Alcohol affects cognition more in older adults than in younger adults.
• Sleep disruption: Alcohol impairs sleep quality, which is already often compromised with age.

Current guidance: if you drink, limit it to no more than one drink per day at 65+. If you have heart failure, atrial fibrillation, liver disease, or take medications that interact with alcohol, your team may recommend avoiding it entirely. If you don’t currently drink, there’s no cardiovascular reason to start.

Cognitive Health and Nutrition

Cognitive decline concerns many older adults, and diet may play a role—though the evidence is more about association than proven causation.

The Mediterranean diet pattern is consistently associated with slower cognitive decline in observational studies, possibly related to its emphasis on fish, olive oil, vegetables, and limited processed foods—though we can’t say definitively that the diet itself is responsible for the observed differences.

Practical points:

• The same eating pattern that supports cardiovascular health (Mediterranean/DASH) is also associated with better cognitive outcomes.
• Fish consumption (omega-3 fatty acids) has been studied for cognitive benefits, though results are mixed.
• There is no strong evidence that any specific supplement prevents cognitive decline in people with adequate nutrition.
• Staying socially engaged, physically active, and mentally stimulated also matters for cognitive health.

If you’re concerned about memory or thinking changes, discuss them with your healthcare team. Nutrition is one piece of a larger picture.

Special Circumstances

Hydration

Older adults are at higher risk of dehydration due to reduced thirst sensation, medications that increase fluid loss, and difficulty accessing water.

If you’ve been told to restrict fluids for heart failure or kidney disease, follow your team’s specific instructions—that takes priority. For others, many older adults do well with roughly 6–8 cups (48–64 oz) daily from water, other beverages, and high-water-content foods, though individual needs vary. Drink a glass with each meal and medication dose, and monitor urine color—pale yellow is ideal.

Eating Alone and Social Isolation

Living alone affects about 28% of adults 65+ and 43% of women 75+.[17] Social isolation is associated with higher mortality.[18]

Eating alone often leads to eating less and eating less well. Strategies that help: community meals at senior centers or churches, Meals on Wheels (which provides both nutrition and social contact), video calls with family during mealtime, batch cooking and freezing individual portions, and eating at a table with real plates rather than in front of the TV.

After Heart Hospitalization

Recovery timelines vary, but a general pattern:

• First 1–2 weeks (in many cases): The priority is adequate intake, not strict restriction. Protein needs may be higher during recovery.[9] Small, frequent meals and oral supplements can help if appetite is poor.
• Over the next several weeks: As appetite improves and energy stabilizes, gradually shift back toward a cardiovascular-protective eating pattern.
• Long term: Work with your healthcare team on a sustainable pattern. Attend cardiac rehabilitation if referred—it provides supervised exercise, education, and support.

Eating Well in Facilities

In assisted living or nursing homes, you may have limited control over food choices, but strategic advocacy helps. Talk to the dietary manager or facility dietitian.

Requests that often work:

• “Can I have my cardiac/diabetic diet order reviewed?” (requires a physician order)
• “Can I get extra vegetables instead of dessert a few times weekly?”
• “Can I get lower-sodium alternatives for soups and processed meats?”

If you or a family member notices weight loss or consistently uneaten meals, bring it to the attention of nursing staff and the physician.

Eating on a Fixed Income

If cost is limiting what you can eat, you’re not alone—roughly 1 in 14 adults over 60 are food insecure.[19]

• Ask about SNAP, Meals on Wheels, and senior meals at community centers.
• Use low-cost staples (beans, oats, eggs, frozen vegetables, peanut butter) as your base.
• If you’re choosing between medications and food, tell your doctor explicitly and ask for help with assistance programs.

The Bottom Line

For many adults over 65, three priorities anchor everything else: take your cardiovascular medications as prescribed, include a source of protein at most meals, and stay adequately hydrated—within the limits your healthcare team recommends.

Beyond that foundation, your functional status—robust, pre-frail, or frail—is the major factor your healthcare team weighs when setting nutrition goals. Appetite challenges are common and deserve attention rather than silent acceptance. Supplements like B12 and vitamin D may help depending on your levels. Alcohol carries more risk with age. And for those who are frail, your team may deliberately prioritize adequate nutrition over strict adherence to standard dietary targets—because after 65, the goal isn’t a perfect lab value, it’s staying strong, steady, and independent. Work with your healthcare team to find the approach that fits your life.

Key Terms

• Sarcopenia: Age-related loss of muscle mass and strength; raises the risk of falls, fractures, disability, and loss of independence.
• Functional status: How well you manage daily activities like walking, dressing, and shopping. Clinicians often group older adults as robust, pre-frail, or frail to tailor advice.
• Anabolic resistance: With age, muscle responds less to dietary protein, so older adults need more protein to build and maintain the same muscle.
• HFpEF (heart failure with preserved ejection fraction): Heart failure in which the heart squeezes with a normal ejection fraction but is stiff and fills poorly. Common in older adults.
• Isolated systolic hypertension: A high top number (systolic) with a normal bottom number (diastolic)—the typical pattern of high blood pressure after 65, driven by stiffer arteries.
• Orthostatic hypotension: A drop in blood pressure on standing that causes dizziness and raises fall risk; more common with age and with certain medications.
• Anorexia of aging: The reduced appetite that often comes with age, arising from physical, medical, and social causes combined.
• Deprescribing: The planned, supervised reduction or stopping of medications that may no longer help or may be causing harm.
