Nutrition Guides for Seniors & Caregivers

Evidence-based answers to the questions family caregivers ask about food and chronic conditions — each article summarizes what published research actually found, with references.

Medications & Food

GLP-1 weight-loss medications and food: timing rules that matter

Oral semaglutide on an empty stomach with a 30-minute wait; injectable GLP-1 drugs have no food timing — plus the diet and exercise evidence from SURMOUNT-4.

Blood pressure and heart medications: what to eat and what to avoid

Rivaroxaban with food, consistent vitamin K on warfarin, grapefruit caution with statins, and potassium from food — not pills.

Diabetes medications and food: metformin rules and what the evidence adds

Metformin with meals, alcohol caution, and the Mediterranean/DASH patterns that support glucose control from the 2025 JAMA review.

Alzheimer's medications and food: a practical guide for caregivers

Most Alzheimer's drugs have no food-timing requirement; sleep medications need a bedtime window; long-term use can affect micronutrients.

Osteoarthritis

What foods help with osteoarthritis pain?

Vegetables, berries, whole grains, legumes, fish and olive oil — the anti-inflammatory pattern behind the evidence.

What foods should you avoid with osteoarthritis?

Processed red meat, sugary drinks, high-sodium snacks and refined grains — and the swaps that help.

Can curcumin help osteoarthritis?

A meta-analysis of 29 RCTs: 120–1500 mg/day for 4–36 weeks reduced pain and inflammation, with caveats.

Does losing weight reduce knee osteoarthritis pain?

Randomized trials show ≥10% weight loss reduces knee pain and joint load — diet plus exercise works best.

Dementia

What should a senior with dementia eat?

Mediterranean-style eating and the MIND diet — the food groups linked to lower risk and slower cognitive decline.

What to do when a senior with dementia won't eat?

The ESPEN 2024 guideline's practical, person-centered steps for mealtime refusal.

Can diet protect against dementia?

What the prevention evidence shows about Mediterranean and MIND diets, coffee and more.

What to do when a person with dementia has trouble swallowing?

Signs to watch and safe-eating strategies from the dysphagia evidence.

Type 2 Diabetes

What should seniors with type 2 diabetes eat?

The ADA 2026 standards: Mediterranean-style, low-glycemic eating with whole grains, legumes, nuts, fish and lean protein.

How much fiber should you eat with type 2 diabetes?

ADA 2026 sets explicit targets: 25–30 g of fiber and 1–2 g of omega-3 per day — and how to reach them.

Chronic Kidney Disease

What should you eat with chronic kidney disease?

Kidney diet advice is shifting to a quality-first framework: balanced, diverse, plant-forward eating with less processing.

Can a plant-based diet help protect your kidneys?

What the research says about plant-forward eating — and why potassium limits still come from your care team.

What should seniors with kidney disease (dialysis) eat?

The 2026 Nature Reviews Nephrology framework: diet quality, variety and plant-forward choices — and why dialysis changes the rules.

Heart Failure

What should seniors with heart failure eat?

Low-sodium, Mediterranean- and DASH-style eating — olive oil, nuts, fish, vegetables and fiber, with processed high-salt foods limited.

Constipation

What should seniors with constipation eat?

The BDA 2025 guideline: 25–30 g of fiber and 1.5–2 L of fluid daily, built on whole grains, berries, legumes and dark leafy vegetables.

Parkinson's

How should protein timing work with Parkinson's levodopa?

Take levodopa 30 minutes before or 1–2 hours after meals; protein redistribution helps — a low-protein diet does not.

What should someone with Parkinson's eat?

Fiber for constipation, low-fat meals for gastroparesis, carb snacks for levodopa nausea — plus caffeine, vitamin C and B vitamins.

Cancer

What should you eat during cancer treatment?

High-energy (25–30 kcal/kg) and high-protein (1.2–1.5 g/kg) eating, with GLIM screening thresholds for malnutrition.

What should you eat after cancer treatment?

Mediterranean-style eating was linked to 23% lower mortality in breast cancer survivors — the evidence and the plate.

What to eat when cancer kills your appetite?

Cachexia isn't simple hunger — screen early, manage the blockers, protect muscle with energy- and protein-dense meals.
