Foods to eat before blood donation

If you want to donate your blood, the most important thing to remember is to stay hydrated both before and after donating the blood. This happens because around half of your blood comprises of water. Another diet factor you need to take care about is a good amount of iron intake as an individual has loss of iron after donating blood. Low iron levels can lead to signs of fatigue and headache.

Iron plays a major role in your body and performs several bodily functions. An iron rich diet is essential if you are planning to donate blood. Blood donation causes low iron levels in your body. Thus, one should try and increase the intake of iron rich foods before donating blood. Iron rich foods include pumpkin seeds, peas, meat, chickpeas, spinach, cashews, almonds, sunflower seeds, whole bread, fish, brown rice and apricots. If you increase the consumption of these foods then there will be less chances of symptoms of fatigue.

2. Vitamin C rich foods

Along with iron rich food items, one should also take care of the vitamin C intake in daily diet. Your plate will be complete if you include Vitamin C rich foods such as oranges, pineapple, lemon, capsicum, green leafy vegetables, tomato and kiwi. Vitamin C plays an vital role in the absorption of iron in the body. So, it is also essential to consume foods that have good amount of vitamin C before donating blood.

Foods to avoid before blood donation

There are many thinks that one should take care of before donating blood. Along with the consumption of some food items, it is also important to avoid certain foods and beverages as they can have a negative effect on your blood. As per Dr. Anjali, here are the foods and drinks to avoid before blood donation:

1. Alcohol


You must not drink alcohol atleast 24 hours before you are going for blood donation. Donating blood that has traces of alcohol is not even healthy for the person who would be receiving blood. Alcohol also makes you dehydrated, and it is not healthy for the donor to donate blood while he is not feeling well. If you consume alcohol, you must try to flush your system by drinking a few extra litres of water. Drinking enough fluids will also help with dehydration.

2. High fat foods

After the blood donation, a sample is tested for certain infections and diseases before transfusion. If we eat a lot of fatty foods like icecreams, bakery food, bacon etc, excessive fats in the blood can hamper the test results, the blood gets rejected and it cannot be used for transfusion. You can start cutting on these foods at least 3 days prior donating blood.

3. Aspirin

Certain medications like aspirin should not be consumed at least 48 hours before the blood donation. Aspirin can interfere with the apheresis platelet product i.e the number of platelets obtained from the donor through centrifugation. You must inform the doctor about all the medications you have been taking since a while.
