White blood cells make up your body's defence against illnesses and diseases. When your immune system works at its peak, foreign germs are instantly killed by the white blood cells before they infect the rest of the body. Certain diseases, stress, a poor diet and hereditary issues can lead to a low white blood cell count.
Balance every meal for a healthy diet. Diet is the single most important aspect to keeping your body healthy. White blood cells are produced and function at their peak when you fill your plate 2/3 full of vegetables, beans and whole grains. The rest should be lean meat or fish.
Eat the right vegetables. Certain varieties of vegetables help increase white blood cells more than others. These include broccoli, cauliflower, spinach, pumpkin and carrots.
Exercise every day for at least 30 minutes. You don't have to do a physical workout, but make sure you keep your body active for 30 minutes. That could mean gardening or walking around a mall. Keep your blood pumping and your muscles working to increase white blood cells.
Drink green tea. Green tea helps stimulate the production of white blood cells. Decaffeinated green tea is better for your body, and 1 or 2 cups a day should do the trick.
Take a multivitamin specific to your age and gender. You don't have to take a pharmacy full of supplements to improve your white blood cell count. A simple multivitamin formulated for you will help substantially. Zinc is important, so make sure it includes a healthy amount of zinc.
Try varying your vegetables at every meal to balance out your vitamin intake.
If you have a low white blood cell count, make sure your doctor checks for every possible reason why. It could actually indicate a more serious problem.
