Kimball Johnson, MD, discusses that not only will apricots, beets, broccoli, turnip greens, carrots, and prunes help to boost your immune system, but red meats, nuts, poultry, and fortified breads will help as well. Fortified bread is bread that has required nutrients and vitamins.
Although you may love French fries and soda drinks, they do not build strong white cells. I cannot count the amount of times I have seen young men at work drinking Mountain Dew to get that extra energy that they feel they need.
I was so glad to hear that Michelle Obama had started the “Let’s Move Movement.” She stresses more physical activity in the schools and fresh fruits and vegetables for school lunches. I have observed that there are some schools that start their day with physical activities in the classroom and others that offer Zumba classes after school. Now if that does not get you moving, I do not know what will.
I recall physical education classes being cut in some of the schools in Michigan. I believe that was a mistake. Physical education and activities are so vital to students.
Getting enough sleep is so vital for protecting your immune system. Getting at least 8 hours of sleep will help protect the immune system.
You don’t want to overlook personal hygiene. Remember to wash your hands for at least 15-20 seconds before preparing food and after using the restroom. I cannot count the times; I have been in the restroom and see someone leave without washing their hands. That disturbs me. I am so happy to see that several buildings including churches, schools, doctor offices and stores have hand sanitizer or moist handy-wipes sitting out and available for others to use. That is a very good intentional effort. I have observed at our church the children must sanitize their hands before taking a snack after Sunday school. Remember it does not take a lot to protect your immune system. If you have not been doing this, you can always start today. It is not too late.
