Nutritional advice for raising hemoglobin levels

Since keeping a healthy hemoglobin level is essential for blood donation, it's critical to monitor your levels. If you are attempting to address a deficiency, get a blood test every few months to check your hemoglobin, serum ferritin, B12, and folate. The following foods are available:
1. Foods High in Iron
Include both heme and non-heme iron sources in your diet since iron is used to make haemoglobin:
- Heme iron (absorbed more effectively):
- liver, red meat (lean cuts)
- Turkey, chicken, and fish
- Non-heme iron:
- Beetroot, kale, spinach
- Tofu, beans, lentils
- Sesame seeds, pumpkin seeds
- Whole grains, such as oats and quinoa.
2. Combine Vitamin C with Iron
Vitamin C improves the absorption of non-heme iron.
- Citrus fruits include oranges and lemons.
- Tomatoes
- Bell peppers
- Strawberries
- Amla, or Indian gooseberry.
Tip: Lemon juice should be added to lentil or spinach dishes.
3. Add Vitamin B12 and Folate
They are essential for the production of red blood cells.
- Sources of Folate:
- Fortified cereals, papaya, broccoli, avocado, dark leafy greens
- Socurces of Vitamin B12 :
- Fortified cereals, fish, meat, milk, and eggs
4. Think about Supplements (if Necessary)
- Iron supplements: Only following a doctor's advice. Excessive use might result in liver problems or constipation.
- Folic acid and B12: They may be prescribed if you are deficient.
- Vitamin C supplement: May improve iron absorption.
5. Steer clear of iron blockers during mealtimes
Restrict these to iron-rich foods for one to two hours:
- Coffee and tea
- Foods or supplements high in calcium (like milk and yogurt)
- Antacids
