Greek Yogurt

It's high in a variety of nutrients and may even have some health benefits. However, it is critical to select the right type of Greek yogurt, as many are loaded with additives such as added sugar. According to a commentary in the October 2020 issue of the journal Food Research International, Greek yogurt is also a fermented food that may help reduce the severity or duration of a COVID-19 episode.
