What to eat to prevent colds and flu
2. Drink green tea which is full of immune boosting anti-oxidants.
3. Try seasoning your meals generously with “warming,” immune-supportive spices such as turmeric and ginger and adding a pinch of cayenne to soups and stir-fries. They’re traditionally used in cooking to get blood flowing, promoting healthy circulation.
4. Douse free radicals and repair and strengthen immune cells with a cascade of antioxidant- and nutrient-rich foods. Prepare a meal with any of these immune-boosting flu fighters: mushrooms, red bell pepper, sweet potatoes or pumpkin, garlic, Brazil nuts, whole grains, and beans.
5. All berries have high concentrations of antioxidants to help fight off flu viruses, but blueberries pack the most punch: When tested against other foods, blueberries were found to have more antioxidants than 40 other fruits and vegetables.
6. Grandma was right to load you up with her own special brew: Researchers are finding that soup works to ward off viruses. One theory is that hot soup raises the temperature in the nose and throat, which creates an unwelcoming environment for viruses that thrive in cool and dry places. Homemade chicken soup has protein groups that have been shown to have anti-viral activity. However, the soup has to be homemade to ward off viruses. Stuff out of a can isn’t going to have the same therapeutic value.
