CNM: Dear Jacquie

Are there natural prevention strategies for colds and chest infections?
It goes without saying that smoking has a negative effect on the immune system. So does alcohol, sugar and caffeine. On the positive side, there are many specific nutrients and foods that you can use to boost your body’s immunity.
Vitamin C boosts your immune system by helping to increase the production of infection-fighting white blood cells and antibodies. It may also increase your level of antibodies that coats cell surfaces, preventing the entry of viruses. Good food sources include parsley, broccoli, bell peppers, strawberries, oranges, lemon juice, papaya, kiwi fruits, cauliflower, kale, mustard greens and Brussels sprouts.

Vitamin E also plays an important role. The main cells of your immune system patrol your body, waiting to attack a dangerous invader. As you age, your immune cells don’t work as well as they used to, so your immune system is weaker. But vitamin E has been shown in studies to significantly increase immune cell activity, thereby making your immune system stronger. Good food sources are spinach, Swiss chard, turnip greens, mustard greens, cayenne pepper, wheat-germ, hazelnuts, almonds, sunflower seeds, asparagus and bell peppers.
Garlic is a natural immune system booster. It may stimulate the production of infection-fighting white blood cells and enhance the efficiency of antibody production. To get the full benefits of garlic, you should eat it raw, or very lightly cooked. Typical garlic pills may have had the active enzymes in the garlic that provide the health benefits, processed out.

Zinc also increases the production of infection-fighting white blood cells, and helps white cells release more antibodies. Good sources of zinc include beef, oysters, crab, turkey, scallops, oats, yoghurt, ginger and spinach.
Probiotics are great for enhancing your immune system, a healthy dose of beneficial bacteria that reside in your gut and make up about 70-80% of that system. Look for naturally sugar-free probiotic plain yoghurts and probiotic capsules. Avoid artificial sweeteners.
Opt for organic, unprocessed, fresh food wherever possible so valuable nutrients can support your immune system, instead of being diverted to help deal with toxins you may be taking in.
Elderberry extracts and certain herbal ranges may help stave off colds.
