Foods that Strengthen Your Immune System

In today's fast-paced world, maintaining a robust immune system is crucial for overall health and well-being. One of the most effective ways to support your body's defense mechanisms is through proper nutrition. By incorporating immune-boosting foods into your diet, you can help fortify your body against infections and illnesses.

Fortified Foods:

 Many foods, such as milk, orange juice, and breakfast cereals, are fortified with vitamin D. These products can be convenient sources of vitamin D, especially for those who may not get enough sunlight exposure.

Sun Exposure:

Spending time outdoors in the sunlight is another way to boost your vitamin D levels naturally. Aim for around 10-15 minutes of sun exposure on your arms and face a few times a week, especially during the summer months.
