Nutrition with Sickle Cell

Key Nutritional Considerations for Sickle Cell

  1. Hydration
    • Why it’s important: Dehydration can trigger a sickle cell crisis, as it increases the risk of blood cells becoming rigid and sickling.
    • What to do: Ensure regular intake of fluids, aiming for at least 8–10 cups of water a day, depending on individual needs. Avoid sugary drinks and caffeinated beverages as they can contribute to dehydration.
  2. Iron-Rich Foods
    • Why it’s important: Many people with sickle cell disease experience anemia, a condition where there is not enough red blood cells to carry oxygen. Eating iron-rich foods can help prevent or manage anemia.
    • What to do: Include sources of iron, such as red meat, poultry, fish, legumes (lentils, beans), leafy green vegetables (spinach, kale), and fortified cereals. Pair iron-rich foods with vitamin C-rich foods (such as citrus fruits, tomatoes, and bell peppers) to help with iron absorption.
  3. Folic Acid (Vitamin B9)
    • Why it’s important: Folic acid helps the body produce new red blood cells, which is especially important for those with SCD, as they have a higher turnover of red blood cells due to the destruction caused by sickling.
    • What to do: Include foods rich in folate like leafy green vegetables, beans, peas, lentils, avocados, and fortified cereals. A folic acid supplement may be recommended by a doctor.
  4. Omega-3 Fatty Acids
    • Why it’s important: Omega-3s help reduce inflammation, improve blood flow, and may help reduce the frequency of pain crises.
    • What to do: Incorporate sources of omega-3s into your diet, such as fatty fish (salmon, mackerel, sardines), flaxseeds, chia seeds, and walnuts.
  5. Protein
    • Why it’s important: Protein is essential for overall body repair and immune function, helping the body recover from illness or crisis.
    • What to do: Include lean protein sources like chicken, turkey, tofu, eggs, beans, lentils, and fish.
  6. Vitamins and Minerals
    • Why it’s important: Sickle cell disease can make individuals more prone to infections and complications, so it’s important to maintain a strong immune system.
    • What to do: Ensure adequate intake of vitamins A, C, and E (for immunity and skin health), and calcium (to support bone health, especially if taking corticosteroids). Good sources include carrots, sweet potatoes, citrus fruits, nuts, and dairy products.
  7. Low-Sodium Foods
    • Why it’s important: High sodium intake can contribute to high blood pressure and kidney complications, which are common in individuals with SCD.
    • What to do: Focus on fresh, unprocessed foods, and limit salt and processed foods such as canned soups, fast food, and salty snacks.
  8. Balanced, Anti-inflammatory Diet
    • Why it’s important: An anti-inflammatory diet may help reduce the frequency and severity of pain crises.
    • What to do: Emphasize a variety of colorful fruits and vegetables, which provide antioxidants and anti-inflammatory compounds, as well as whole grains and legumes. Avoid excessive intake of processed foods, sugars, and refined carbs, which may promote inflammation.
  9. Managing Cravings and Weight
    • Why it’s important: Some individuals with sickle cell may have changes in appetite or experience weight fluctuations due to the illness or treatments.
    • What to do: Focus on eating small, balanced meals to maintain stable energy levels. Consider consulting with a dietitian to develop a plan if there are concerns about weight management or specific nutrient needs.

Foods to Consider

  • Whole grains: brown rice, oats, quinoa, whole wheat bread
  • Leafy greens: spinach, kale, collard greens
  • Berries and citrus fruits: strawberries, oranges, lemons
  • Nuts and seeds: almonds, sunflower seeds, chia seeds
  • Lean protein: chicken, turkey, eggs, tofu, beans, lentils
  • Healthy fats: olive oil, avocado, fatty fish

What to Avoid

  • Excessive salt: Canned foods, salty snacks, and processed meats
  • Sugary foods and drinks: High-sugar snacks and beverages can worsen fatigue and inflammation
  • Caffeine and alcohol: These can cause dehydration, especially during pain crises
