Zinc may be your best bet against the common cold
Unlike vitamin C, which studies have found likely does nothing to prevent or treat the common cold, zinc may actually be worth a shot this season. The mineral seems to interfere with the replication of rhinoviruses, the bugs that cause the common cold.
In a 2011 review of studies of people who'd recently gotten sick, researchers looked at those who'd started taking zinc and compared them with those who just took a placebo. The ones on zinc had shorter colds and less severe symptoms.
Zinc is a trace element that the cells of our immune system rely on to function. Not getting enough zinc (Harvard Medical School researchers recommend 15-25 mg of zinc per day) can affect the functioning of our T-cells and other immune cells. But it's also important not to get too much: an excess of the supplement may actually interfere with the immune system's functioning and have the opposite of the intended result.
So instead of chugging fizzy drinks loaded with vitamin C, stick to getting the nutrient from food. Strawberries and many other fruits and veggies are a great source. And if you aren't getting enough zinc in your diet, try a zinc supplement. Chickpeas, kidney beans, mushrooms, crab, and chicken are all rich in zinc, and zinc-rich lozenges may also help boost your intake.
