1. Nuts and Seeds

Nuts and seeds are packed with essential nutrients that can boost your immunity. These include vitamins, minerals and antioxidants.

They contain anti-inflammatory properties and are high in dietary fiber, making them an excellent addition to any diet.

2. Dark Leafy Greens

Dark leafy greens like spinach, kale and swiss chard are packed with vitamins C, K, folate and beta carotene that support your immune system. Plus they supply other essential nutrients like iron and potassium as well.

Vitamins B6 and B12, as well as zinc, are essential for a strong immune system. Not only do they assist in producing antibodies in the body but they also support nerve cells and red blood cells by maintaining their health.

Eggs are an excellent source of omega-3 fatty acids and choline, both beneficial to brain health. Furthermore, eggs may reduce a person’s risk for heart disease and cancer by helping build stronger bonds between cells.

Whole grains provide essential nutrients and a range of phytochemicals to support the body’s immune system. These include B vitamins, fiber, zinc and iron.

Whole grain products differ from refined grains in that they retain both their bran and germ after milling. Furthermore, these grains still contain the starchy endosperm which provides carbohydrates and protein but in a more concentrated form.
