Giving blood is something that almost anyone over the age of 17 can do, provided they are in good health and weigh at least 110 lbs. Giving blood can be done for many reasons -- to contribute to research, to save a life or to help a friend or family member in need. There are different kinds of blood donations, including whole blood, or just platelets or plasma. Some easy steps are recommended in preparation for an appointment to give blood.
Step 1
Drink plenty of water. According to American Red Cross, it is important to hydrate yourself well before giving blood. On the day of your donation appointment, consume plenty of water with your breakfast.
Step 2
Consume iron-rich foods. The ARC also suggests foods that are high in iron, not only for breakfast on the day of your appointment but also in the weeks leading up to it. Chicken, beef, pork and fish are examples of iron-containing meat products. The best source of iron for your blood is meat products because the iron in them is absorbed at a much higher rate than iron found in vegetable or whole-grain sources.
Step 3
Avoid food that is high in fat. The San Diego blood bank requests that its donors eat food that is low in fat, or dietary lipids, not only the morning before the test but also the day before it. If the blood drawn from a donor is unusually high in lipids, it cannot be tested for evaluation. This instance would prevent the blood donation from being used for research or transfusion. Avoid margarine, baked goods such as doughnuts and cakes, cookies, french fries, chocolate or fatty meats, such as bacon.
Step 4
Eat foods that are heart healthy and will improve your bloods chances of being used for research or transfusion. The San Diego Blood Bank recommends fruits that are high in iron, like prunes or peaches, beans, lentils, skinless poultry that has been roasted and not fried, whole-grain breads and nonfat dairy. These are foods that are both sources of iron and low in fat.
Tips and Warnings
- Most blood donor clinics require some form of identification. Phone ahead to make sure that you are prepared.
- After giving blood you may feel lightheaded. Plan ahead and have a beverage and light snack to enjoy while your sit and rest for a few minutes after your donation has been completed.
