Take your vitamins
Even if you never eat junk food or miss meals, your body may still need a bit of help getting all the nutrients it needs to stay strong, because many of the refined foods in a typical Western diet have been depleted of various vitamins and minerals. This is where a good multivitamin may help. In addition, boosting your intake of the nutrients below may help prevent marginal deficiencies that could lower your immune system defenses, potentially making you more susceptible to infections:
Excessive stress may lead to suboptimal immune system function, potentially making the body less able to fend off everything from bacteria and viruses to serious diseases. Finding ways to relax is an important part of a well-rounded health program. Give the following a try:
