Zinc may ease cold symptoms
Zinc supplements can help relieve cold symptoms such as: a scratchy, dry throat, and help soothe a cough. Doctors believe that zinc-based medications can even destroy the flu virus. This theory has not yet been proven, but it is known that zinc prevents the proliferation of viral particles. Scientists made this conclusion based on several experiments involving 2,121 people. High doses were more effective than low doses, but you need to be careful with the amount so as not to harm your health. It is not yet known what dose is effective; in case of an overdose, the patient may experience side effects such as an unpleasant taste in the mouth, nausea, and also suffer from bouts of diarrhea.
Zinc will reduce the duration of the disease
According to experts, it is taking zinc-containing drugs that will help with colds. According to the results of the studies, zinc reduces the duration of the disease by almost 40%. This effect is explained by the fact that zinc has an effect on the immune system and is important for the body's resistance to infections.
Placebo effect
Scientists suggest that the placebo effect plays a significant role in successful recovery. This means that some kind of connection between the mind and body helps make the treatment more effective. Therefore, a person’s attitude towards recovery, taking medications in combination with rest and plenty of fluids will help get rid of the disease faster.
Proper doses of zinc boost immunity
As we have already said, zinc is a vital mineral for human health. It keeps our immune system functioning at an optimal level and is an excellent defender against viral attacks. Zinc deficiency is dangerous for particularly vulnerable groups of the population – the elderly and small children. You can maintain a normal amount of zinc in your body with foods rich in this element, such as legumes (beans, lentils), beef, poultry, nuts, cereals and whole grain products.
