Garlic:
Garlic dramatically helps in boosting the immune system and reduces the risks of getting infectious diseases. The garlic clove contains alliin, which deliberately fights against the attack of micro-organisms like bacteria, viruses, and fungi. When we ingest the whole garlic by either chewing it by mouth or by crushing it in the stomach, it converts into its active compound, i.e., allicin, which helps in fighting the attack of microbes. Garlic is a superfood because it contains a package of sulphuric compounds, potassium, and calcium, which directly play a role in protecting the immune system.
