How does nutrition aid your immune system?

Nutrition is important for overall health and consuming a well-balanced and nutritious diet can help support your immunity in a number of ways.

Although no one food provides better immunity, a diet that contains all of the essential nutrients (including macronutrients and micronutrients) that your body needs can help promote better function of immune cells and improved defenses against pathogens.

Let’s take a closer look at how different nutrients can aid your immune system.

Vitamins and minerals

All micronutrients (vitamins and minerals) are important for health, especially vitamins C, D, and E and the mineral zinc.  Each of these micronutrients helps contribute to better development, activation and functioning of immune cells.

Antioxidants

Fruits, vegetables and whole grains are packed full of antioxidants, which are essential compounds for the body. They help reduce oxidative damage in the cells to promote better functioning of immune cells

Proteins

Protein is vital for the production of enzymes, antibodies and other essential cells that can contribute to stronger immunity. Protein deficiency can negatively impact immunity and compromise your body’s ability to produce strong immune cells.

Omega-3 fatty acids

Found in oily fish, nuts, and seeds, omega-3 fatty acids are unsaturated fats that have potent anti-inflammatory. Since inflammation can negatively impact your immune system, consuming adequate omega-3s can potentially help improve your immunity.

Probiotics and prebiotics

Probiotics are beneficial bacteria, such as Lactobacillus and Bifidobacterium, that support your digestion and promote good gut health, which is closely linked to immune function. Prebiotics are fibers that are found in many fruits and vegetables. They fuel the probiotic bacteria in your gut and can help improve your overall immune function.
