Danger from Chronic Alcohol Ingestion Research suggests that those who routinely consume significant quantities of alcohol may damage their immune systems and are thus at greater risk for the stimulation of carcinogenesis, the onset of cancer. The immune system is the body's protection against damage from invading bacteria, viruses, and cancers. In order for it to function properly, it must have the support of proper nutrition. Nutritional immunology is the field of study dealing with this support. Free radicals have been linked to the immune system damage that accompanies normal aging.
Vitamins play a critical role along with trace elements in maintaining the human immune system.
Several herbs have demonstrated the ability to enhance and strengthen the immune system. These include echinacea, ginseng, and grape seed-skin extract. Other nutrients that have shown a positive effect on immune function are soy protein extract, whey extract, L -carnitine, and coenzyme Q10. Useful hormones and extracts are melatonin, DHEA, KH3, and thyroid-stimulating hormone. Biostim, a European medication, enhances the immune system as shown by carefully conducted trials.
