Probably most important way to maintain immune system is to intake healthy food more frequently.
You can start your day with Avocado toast, piece of cheese and 3 egg whites or full eggs, and get all nutrients needed to start your day perfectly, breakfast like that have around 350cal and is considered as strong breakfast.
During day you can make for example Carrot, Orange or Lemon juice.
I suggest you to drink it 2 times per day.
You always can balance your favorite food with healthy food.
Benefits of balanced food are your overall health.
Adding your daily workout routine will give you lifestyle you want.
Thank you.
