What types of food help avoid getting a cold or sick?

Home-cooked, natural: A well-balanced diet of natural foods with plenty of vegetables, cooked at home, is very safe. To maintain good health, one eats a variety of foods, and avoids prepackaged foods with excessive artificial stuff in them. Home-cooking is less likely to cause "food poisoning" than eating out all the time. Foods don't prevent colds, but public places like restaurants have plenty of people's viruses.

Good health: Staying healthy from colds depends greatly on good handwashing practices as well as foods. Nevertheless, eating healthy with plenty of colorful veggies and fruits that have vitamin c and other antioxidants, garlic, etc, may be good. Lean proteins and omega 3 fats might calm inflammation and help your immune system perform its job better.

Fruits veggies: A well balanced diet complete with fruits and veggies is essential to avoid colds. Adequate sleep is also a must avoid alcohol and smoking too. Good luck and stay well!
