Best Foods to Naturally Boost Your Immune System
Your immune system is your body’s defense army. The food you eat plays a direct role in how strong that army is. Here are the top natural foods that help keep infections at bay and your energy levels high.
Why food matters for immunity
Vitamins, minerals, antioxidants, and healthy fats all contribute to a resilient immune system. Unlike supplements, whole foods deliver nutrients in the right balance, along with fiber and plant compounds that enhance absorption and effectiveness.
