Nutrição Pós-AVC: Alimentos a Limitar e a Incluir para Recuperação Ótima

Dietary Principles After Stroke

Post-stroke nutrition focuses on three pillars: secondary prevention to reduce recurrent stroke risk, neurorehabilitation support to aid brain recovery, and complication management addressing dysphagia, malnutrition, and sarcopenia. Recommendations should be individualized based on stroke subtype, comorbidities, and nutritional status.

Foods to Limit or Avoid

Category	Examples	Rationale
High Saturated Fat	Fatty red meat, processed meats, full-fat dairy, butter, lard, coconut/palm oil, fried foods	Raises LDL cholesterol → accelerates atherosclerosis; pro-inflammatory
Trans Fats	Partially hydrogenated oils: commercial baked goods, margarine, fried fast food, snack foods	Raises LDL, lowers HDL, increases inflammation and endothelial dysfunction
High Sodium	Processed meats, canned soups, soy sauce, pickles, salty snacks, restaurant meals, bread	Elevates blood pressure (major stroke risk factor); target <2,300 mg/day (ideally <1,500 mg)
Added Sugars	Sugar-sweetened beverages, candy, pastries, sweetened cereals, flavored yogurts, condiments	Increases triglycerides, weight gain, insulin resistance, inflammation
High-Cholesterol Foods	Organ meats, egg yolks (>1/day), shellfish (moderate)	Dietary cholesterol modestly raises serum cholesterol; limit if hyperresponder
Alcohol (Excess)	>2 drinks/day (men), >1 drink/day (women)	Raises BP, atrial fibrillation risk, hemorrhagic stroke risk, medication interactions
High-Mercury Fish	Shark, swordfish, king mackerel, tilefish, bigeye tuna	Neurotoxin; may impair cognitive recovery
Ultra-Processed Foods	Packaged meals, instant noodles, reconstituted meats	Low nutrient density, high sodium/sugar/unhealthy fats, additives

Foods to Emphasize (Mediterranean/MIND/DASH Patterns)

Category	Examples	Benefits
Fruits & Vegetables	Berries, leafy greens, cruciferous, citrus, colorful variety (≥5 servings/day)	Antioxidants, polyphenols, potassium, fiber, nitrate → lower BP, reduce oxidative stress
Whole Grains	Oats, quinoa, brown rice, whole wheat, barley, buckwheat	Fiber, magnesium, B vitamins → lower LDL, improve insulin sensitivity
Lean Protein	Fish (salmon, sardines, mackerel – omega-3), poultry, legumes, tofu, low-fat dairy, eggs	Muscle maintenance, anti-inflammatory omega-3s, satiety
Healthy Fats	Extra virgin olive oil, avocado, nuts (walnuts, almonds), seeds (flax, chia)	MUFA/PUFA → lower LDL, raise HDL, improve endothelial function
Low-Sodium Flavorings	Herbs, spices, garlic, citrus, vinegar, pepper, salt-free blends	Palatability without sodium
Fermented Foods	Yogurt, kefir, kimchi, sauerkraut, miso	Probiotics → gut-brain axis modulation, inflammation reduction

Special Considerations

• Dysphagia: Texture-modified diets (IDDSI levels); speech-language pathologist guided; thickened liquids.
• Malnutrition Risk: 20–50% post-stroke; screen with MNA-SF; oral nutritional supplements if intake inadequate.
• Medication Interactions: Warfarin + vitamin K (consistent intake); statins + grapefruit; ACEi/ARB + potassium.
• Glycemic Control: Diabetes management critical; consistent carbohydrate distribution.

Practical Implementation

1. Assess nutritional status (weight history, intake, labs, SLP evaluation).
2. Set individualized calorie/protein targets (25–30 kcal/kg, 1.2–1.5 g/kg protein).
3. Meal plan with patient/caregiver preferences.
4. Monitor: weight, labs (prealbumin, electrolytes, glucose, lipids), functional status.
5. Multidisciplinary team: RD, SLP, OT, nursing, physician.

Post-stroke diet is not restrictive but redirective—toward nutrient-dense, anti-inflammatory, vascular-protective foods that support brain recovery and prevent recurrence.
