Colds are a relatively common type of illness, often occurring in people whose immune functions are compromised. For such patients, it is recommended that they consume foods high in protein and vitamins. Commonly, individuals catch colds due to inadvertent exposure to cold environments leading to viral infections.

For such cold sufferers, it is generally advised to consume items like yogurt and milk, as yogurt has high nutritional value due to its fermentation process. It typically contains high-quality proteins, probiotics, calcium, and various vitamins, including B1 and B6. Therefore, consuming yogurt when suffering from a cold can greatly supplement the nutrients needed by the body, and indirectly boost the patient's immunity. Thus, yogurt is advisable during a cold.
