    Dietary recommendations for good immune health

    • Eat regular meals to stabilize your blood sugar

    • Never skip breakfast

    • Limit simple sugar consumption. Bacteria love to feed on simple sugars! Weakens immune system, decreases number of WBCs and reduces their ability to kill viral or bacterial infections.

    • Maintain an ideal body weight. Obesity is a risk factor for influenza

    • Increase intake of bright/colourful veggies: Fruits and veggies are high in antioxidants (Vit A, C & E), Zn, bioflavonoids o A lack of nutrients decreases the immune response

    • Incorporate garlic and onions into your diet: Contain alliin and quercitin, two immune-modulating and immune boosting phytochemicals that are scientifically proven to contain antiviral and antibacterial properties

    • Remove preservatives, artificial sweeteners and colourings, flavourings, sodium

    • Avoid refined/allergenic foods – can increase inflammation in the body

    • Get plenty of fluids. Allows for improved lymphatic circulation. Dry respiratory tracts have been shown to produce a much more hospitable environment for viruses to invade than a moist environment. o Water is also very important in the function of white blood cells o Optimally you need to drink half an ounce of water for each pound of body weight to thin mucus secretions. (at least 8 cups/day)

    • Decrease caffeine intake – causes increase in cortisol leading to a decreased immune system

    • Incorporate good sources of protein into your diet: o Lean meats, eggs (if not sensitive), and legumes o Ensuring adequate protein is essential to produce antibodies and white blood cells that are responsible to fight off bacteria

    • Nuts are a good source of protein and also contain high amounts of arginine, an amino acid responsible for regulating immune function • Eat fish 2-3xweek: especially cod, contains high amounts of vitamin D, a nutrient that is key to optimal immune function

    • Incorporate food sources of probiotics: Fermented foods help to feed the good bacteria in the gut:

    – Plain yogurt: contains acidophilus and lactobacillus for optimal digestive health and thus immune function.

    – Kefir

    – Sauerkraut (fermented cabbage)

    – Kimchi (Korean spicy cabbage)

    – Tempeh (a fermented soybean product)

    - Should say contains “Live” or “Active” cultures


    I hope these tips help keep you healthy this season.
