Now, new research on calorie restriction suggests that feeding a cold may have some biological basis.
During the last 80 years of research, calorie restriction with optimal nutrition has proven to dramatically increase life span and dramatically reduce signs of aging.
However, several studies have challenged calorie-restricted laboratory animals with influenza infections.
So far, the results show calorie-restricted animals have less resistance to infection compared to the “feed a cold” group (animals that could eat all the nutritionally balanced lab chow they wanted).
Researchers found that calorie restriction
in both young and aged animals (Gardner, Calorie restriction decreases survival of aged mice in response to primary influenza infection, Journals of Gerontology, 2005, and Ritz, Energy restriction impairs natural killer cell function and increases the severity of influenza infection in young adult male C57BL/6 mice, Journal of Nutrition, November 2008).
Considering green tea flu research that shows up to 100% survival in influenza infected animals with the addition of tea, we need to find out if the above results could be modified with the addition of green tea chemicals like EGCG or theanine.
