inducing but equally troublesome seasonal flu are afflictions that everyone these days is seeking immunization against. For those people disinclined to take flu vaccines or strong medication, Saudi Gazette has spoken to a dietician and compiled some natural ways to immunize the body against the flu. Nutritionists make it clear at the onset that there is no specific type of food that can protect from the A (H1N1) virus, for instance, but the consumption of certain types of food can increase the body's immunity to it. Following a certain diet plan can therefore help in protecting against swine flu. “Proper nutrition is critical to improve the immune response,” stated Ruqiya Al-Usmani, the consultant chief of the Nutrition and Dietetics department and a diabetic instructor in Bash Hospital Jeddah in an interview with Saudi Gazette. “Perhaps the single most important aspect of boosting the immune system is also the simplest: including plenty of immune system boosters in the diet.” She added: “the immune system's function is to clear the body of foreign substances or antigens such as bacteria, viruses or parasites through a combination of defensive weapons which adapt smoothly to the situation.” For example, if someone is bitten by an insect, the immune system sends cell groups to travel along the blood flow, tracking unfamiliar chemical agents. When found, these cell groups are programmed to eradicate the agents with biochemical weapons, even the most stubborn and familiar of viruses like the common flu. Immunize yourself naturally from the following sources: Garlic: This simple plant is at the top of every immune system-enhancing list. The garlic exhibits notable antibiotic, antiviral and anti-fungal properties. Ginger: Ginger stops head and chests congestion, malaise and chills as well as the scratchy throat sensation. It fights the flu as an alternative medicine. Yogurt: Yogurt packs a healthy dose of the good kind of bacteria that can protect the body against harmful bacteria and infections. Red Bell Pepper: It contains a high percentage of vitamin C, instrumental in fighting the flu. Tuna: Surprisingly, this common fish contains a number of important nutrients that boost the immune system including selenium and zinc. Broccoli: This contains significant levels of vitamin A, C, E and beta carotene which are the top most immune system nutrients. Yellow or green squash: This is packed with beta carotene which is an excellent immune enhancer. Leafy greens: Always good for almost everything, these include spinach, kale, turnip greens and are a good source of vitamin E and beta carotene. Lean beef: Surprisingly, beef is considered important for the immune system since it is a top source of zinc. Green tea: There is strong evidence that compounds in tea are provide offensive and defensive functions that act directly on invading microbes like viruses. Mushrooms: Shitake mushrooms, in particular, are listed near the top as an immune system booster. Peppermint: Peppermint is widely used to treat the cough, as it helps reduce the cough reflex. Dr. Al-Usmani also provided some natural sources of vitamins, zinc, cartenoids, Omega 3 and Selenium - all of which boost the immune system: Vitamin C Guava, papaya, strawberries, kiwi, cantaloupe, orange, grapefruit and pineapple Vitamin E Seeds, vegetable oils and whole grains Zinc Beef, oysters, turkey (dark meat) and beans Cartenoids Sweet potatoes, carrots, kale, spinach, cilantro, thyme, turnip greens Omega 3 Fish, flaxseeds, walnuts, beans, winter squash and olive oil Selenium Cereals, nuts, legumes, beef and tuna
