Dr. Mercola also shares this:
According to the CBS News study, when you come down with chills, fever, cough, runny nose, malaise and all those other "flu-like" symptoms, the illness is likely caused by influenza at most, 17 percent of the time, and as little as 3 percent! The other 83 to 97 percent of the time it's caused by other viruses or bacteria.
My simple and short answer for what is causing a cold or flu has always been that it’s due to an impaired immune system. That’s still true. However, research has confirmed that “catching” colds and flu may be a symptom of an underlying vitamin D deficiency! Less than optimal vitamin D levels will significantly impair your immune response and make you far more susceptible to contracting colds, influenza, and other respiratory infections.Although there are many ways you might end up with a weakened immune system, the more common contributing factors are:
- Vitamin D deficiency, as previously mentioned
- Eating too much sugar and too many grains
- Not getting enough sleep
- Insufficient exercise
- Inadequately managing emotional stressors in your life
- Any combination of the above
In order to prevent the flu, children and adults need 35 IU of vitamin D per pound of body weight. So, for example, a child weighing 57 pounds would need 2,000 IU a day of vitamin D.
Adults typically need an average of 5,000 IU per day—but some adults have to take 20,000 to 30,000 IU daily to get their vitamin D level up to optimal levels. Exactly how adults absorb and process vitamin D so differently is still somewhat of a mystery, so the only way to know if your vitamin D level is therapeutic and nontoxic is by having your blood tested.
Thank you Dr Mercola!!!
