2. Frequent colds and flu
Consuming fluids or foods high in sugar content can cause your immune system to lose its capability to attack sickness-causing bacteria. For the immune system to fight the dangerous bacteria present in the body powers its cells using vitamin C, a substance with a similar chemical structure to glucose. When your blood sugar levels are high, the immune system uses glucose instead of vitamin C, which has no power against flu bacteria. And when this happens, your immune system is dealt a mighty blow by the disease.
To avoid such a situation, reduce the amount of sugar you consume when you’re vulnerable to cold or flu. Also, eat foods rich in nutrients and vitamins C and E, and beta-carotene and zinc.
