1. Immune System Overview

The immune system is multilayered, allowing for a complex and organized response to pathogens. It is composed of the innate and the adaptive immune responses. The innate immune response is nonspecific and quick to react, whereas the adaptive immune response is slow to respond yet specific in nature. Nutrition and lifestyle have an impact on the function of these layers.

2. Health Fraud in the Era of COVID-19 and Beyond

Health fraud is defined as deceptive practices marketing unproven products to prevent or treat disease. The warning signs of health fraud include the use of medical jargon and terms such as “all-natural” or “clean.” Fraudulent products can also promise money-back guarantees and limited availability to promote quick sales.

3. Impact of Macronutrients on Immune Function

Nutrition can have an impact on immune function. Macronutrients include total calories, carbohydrates, protein, and fiber. Inadequate calories and protein can suppress immune function by limiting production of white blood cells. Carbohydrates and dietary fiber support the immune response via the gut microbiota. A balance of macronutrients is essential for optimal immune function.

4. Impact of Micronutrients on Immune Function

Micronutrients, including vitamins and minerals, are essential for the maintenance of the immune system. Key nutrients include zinc, vitamin D, vitamin C, and omega-3 fatty acids. The Recommended Dietary Allowances (RDAs) are designed for people who are well, and during illness, these requirements increase. Supplementation is often needed to support a competent immune system during physiological stress.

5. Impact of Lifestyle on Immune Function

Lifestyle factors also can have a profound impact on immune function. Sleep deprivation and alcohol are common factors that can suppress immune function. Lack of sleep can increase stress hormones and alter white blood cell function. Alcohol consumption can impair protein synthesis and increase the likelihood of infection. Lifestyle, along with diet, can have a profound impact on immune health.
