Your body has ways of protecting bacteria

Your body has ways of protecting you from these bacteria; any foreigner that enters through the mouth and makes it to your stomach usually doesn’t last long. Your stomach produces hydrochloric acid, a powerful acid that actually sanitizes the foods you eat and kills any harmful bacteria. If your stomach acid is low and the bug makes it past this line of defense, the good bacteria in the small intestines will eat up the invader. However, low stomach acid (this becomes naturally lower as you age) along with lowered acidophilus (good bacteria in your intestinal tract that is easily killed off by antibiotics and caffeine) makes you vulnerable to invaders and can cause your body to react violently with diarrhea, vomiting, and fever. These symptoms are the body’s last resort to keep you safe from poisoning.
Your best supplemental protection against foodborne illness is to supplement with food enzymes that contain a small amount of hydrochloric acid before you eat. Adding acidophilus capsules every day—especially when traveling—will also help protect you. Acidophilus is best taken in entericcoated capsules so that it has a chance to reach the intestinal tract before being bombarded with your stomach’s digestive secretions. This protects these critters from being killed before they get a chance to make it to your intestinal tract.
