White blood cells, or leukocytes, are the immune system's frontline defenders against infection and disease. While no single vitamin can be labeled as the "best," several key vitamins and minerals play crucial roles in white blood cell production, function, and overall immune health.

According to the World Health Organization, iron deficiency anemia affects nearly 30% of the global population, posing a significant public health concern. This widespread nutritional deficiency can profoundly impact various physiological functions, including the immune system. A lack of iron weakens the body's natural defense against illness and infection.

According to the National Institutes of Health, malnutrition can significantly impair immune response and increase susceptibility to infections. This fact directly addresses the critical question: does a good diet boost the immune system? The answer is a resounding yes, though the process is more about supporting and optimizing rather than magically 'boosting'.

Over one billion people worldwide are estimated to have vitamin D deficiency or insufficiency, a condition linked to impaired immune function. But does low vitamin D lower the immune system, leaving the body vulnerable to infections and chronic diseases? Emerging research suggests a complex and significant relationship between your vitamin D levels and the effectiveness of your immune response.

According to the World Health Organization, unhealthy diets are responsible for over a quarter of total deaths from noncommunicable diseases. This highlights the significant and complex role that nutrition plays in illness, both in its prevention and in the management of its symptoms.

Despite a long-held belief that you should 'starve a fever,' medical consensus today confirms your body actually needs more energy when fighting an infection. This counters the myth, leaving many to wonder, should you eat less when sick? The short answer is no, and understanding why is crucial for a speedy recovery.
