Getting Sick Frequently
If you often catch colds and other viruses, it could mean that the immune system is having issues defending the body against these intruders. One of the best ways to keep immunity strong is to eat a healthy diet. You need to consume vegetables, as well as legumes, fish, and other sources of healthy proteins.
Fermented foods are essential, such as kimchi and sauerkraut, which aid the digestive system while improving immunity. You should also not forget to drink at least eight glasses of water daily.
