These days the cases of low immunity and allergies to a range of foods, everyday chemicals, cosmetics and environmental hazards are increasing. People, unsuspectingly, take certain health supplements that weakens their immune system. E.g. A multi vitamin tablet can impede the body's immunity functions in the same way as a high fat breakfast, high sugar diet, high soda drink, food preservatives and pesticides. There are other causes for low immunity - sleeplessness and stress. There are certain foods which can cause allergies, and these are used to keep a person awake for long such as coffee, colas, tea, chocolate etc. One of the chemicals found as fat substitute in potato chips - olestra - which was previously believed to be healthy fat substantiate, was found to be unhealthy compound, which binds the vitamins and minerals of foods, necessary for a healthy immunity.

Olestra binds vitamin A, vitamin E, vitamin E, vitamin D, vitamin K and carotenoids in foods. There are certain easy ways to boost stamina and immunity and some herbal cures offer better ways to enhance immunity, avoid allergic reactions to everyday exposures and protect the body from trigger factors (e.g. stress, endocrine imbalance, sleeplessness etc.) of allergic reactions.
