Which foods can enrich white blood cells?

Expert Answer

Jennifer Serafin, N.P. is a registered nurse and geriatric nurse practitioner at the Jewish Homes for the Aged in San Francisco.

There are many opinions about which foods are best for boosting white blood cells (immunity).  However, there are few studies that prove these claims.  My best advice would be to eat a balanced diet with lean meats, plenty of fruits and vegetables, nuts, legumes (beans), and low fat diary.   Healthy fish, such as tuna and salmon, contain fatty acids that have been shown to benefit health.

If your diet is lacking, you can take a mulitivitamin, but there is little research to show this to be a benefit.
