Your best bet against colds, flu, and other infections is to keep your immune system in good working order. But there are quite a few factors out there working against your immune system, and it’s up to you to guard yourself against them.
Sugar intake directly affects the ability of the immune system’s white blood cells to fight off infection. There’s also significant evidence that chlorinated water and water containing fluoride weaken the immune system. The National Cancer Institute has published articles showing an increase in cancer risk from chlorinated water. If cancers are increased, that means that the immune system must be weakened. And there are many studies showing that fluoride, at levels found in our drinking water (and in our tissues if we drink that water), interferes with both the mobility of our white blood cells and their ability to engulf and kill germs. So in addition to keeping refined sugar intake to a minimum, try to stick to bottled or distilled water.
Vitamin and mineral supplementation is also an important factor in preventing infections like colds, flu, and bronchitis. Adults should take 1,000 milligrams of vitamin C at least three times daily, and 40,000 units of vitamin A, 50 milligrams of zinc, and 2 milligrams of copper per day.
And there are also a wide variety of botanical remedies that can help boost the immune system as well, such as goldenseal (500 milligrams twice a day) and garlic (two pure garlic-oil capsules a day).
