Soy and Brain Damage

Brain damage is the partial or complete destruction or degeneration of brain cells. It may occur due to a variety of conditions including injury, reduced blood or oxygen supply to the brain, poisoning, infection and neurological illnesses. Brain damage may or may not lead to permanent disability. In fact, the location and extent of damage play a key role in the outcome, and treatment depends on the underlying cause and symptoms. Certain foods and supplements such as soy may help prevent brain damage.

About Soy

Soy has been a part of Asian cuisine for centuries. The soy plant belongs to the pea family and produces beans that are high in proteins and estrogenlike isoflavones. Soy foods are available as milk, cheese, yogurt, nuts and tofu. Its supplements are also available as capsules and tablets. Apart from being a rich source of protein for vegetarians, soy has also been used traditionally to treat a wide range of conditions including osteoporosis, menopause, high cholesterol and certain cancers. The appropriate form and dose of soy depends on the age and overall condition of the individual.

Link Between Soy and Brain Damage

Increased intake of soy foods may reduce the risk of ischemic stroke that occurs when the blood vessels of the brain are blocked by clots, according to a study in the 2009 issue of the journal "Neuroepidemiology." Some soy derivatives like soy lecithin are a source of phosphatidylcholine, an essential element in the lining of the brain cells. It may, thereby, benefit Alzheimer's patients and prevent memory loss in smokers, says Phyllis A. Balch, C.N.C., author of the book "Prescription for Herbal Healing." The author further states that soy isoflavones possess significant antioxidant activity and may slow the progression of Alzheimer's disease.

The Hypertension Connection

Along with neuroprotective properties, soy isoflavones and phytoestrogens may also help prevent hypertension in certain strains of laboratory mice, says a study published in the April 2011 issue of the journal "Phytomedicine." Hypertension is the most common risk factor for stroke and is responsible for about 50 percent of ischemic stroke, as per the World Heart Foundation.

Side Effects

Soy foods and supplements are generally safe to use, although excessive intake may lead to upset stomach, nausea, bloating and diarrhea. Soy isoflavones may also increase the risk of breast cancer and endometrial hyperplasia, or thickening of the uterus lining. The supplements may also interfere with certain osteoporosis and breast cancer medications.

Precautions

Always talk to a doctor before taking soy products to prevent brain damage. Inform the doctor about pre-existing conditions and any other medications you might be taking. Also, production and distribution of some soy products may not be regulated by the Food and Drug Administration. Hence, talk to a pharmacist to ensure the efficacy and safety of the product.
