2. Frequent colds and flu
Eating or drinking too much sugar blocks the immune system cells from attacking bacteria when you get sick. The vitamin C that your body needs to fight flu is very similar in its chemical structure to glucose. Instead of looking for and working with vitamin C, your immune system takes glucose that has zero power against flu bacteria. Therefore, instead of fighting a disease your immune system suffers from it.
To prevent such a scenario, cut down on sweets when you’re at risk of getting a cold or flu and eat more fruits and vegetables that are rich in nutrients and vitamins C and E, as well as beta-carotene and zinc.
and try to cut down your daily intake of sugar. Find sugar in natural products like fruits, vegetables, nuts, or cereal.
