Insufficient protein in the diet resulting in malnutrition results in an impaired immune system. At the same time the micronutrients, zinc; selenium; iron; copper; vitamins A, C, E, and B-6; and folic acid have important influences on our immune stystem

The immune system is dynamic and complex. But a balanced, healthy diet provides it with a steady supply of energy and the micronutrients required to keep it healthy. A healthy immune system requires a good balance between tolerance (to avoid autoimmune system reactions) and reaction to threats from disease.

This means that whether you’re entirely plant-based in your diet or have a more flexible approach or are entirely meat-eating, you still need to know where you get your protein and essential micronutrients.

Foods that have been scientifically recognized to boost the immune system, include garlic probiotic organisms found in fermented foods, including traditionally cultured dairy products and newer kinds of fermented milks, green tea, almonds, ginger, broccoli and spinach.

If you try to include these foods in your diet remember that too much can be as bad as too little, so make sure you follow meal plans and recipes that have a fully worked out rationale and nutrition plan.
