Soy consumption has been a staple in Asian diets for thousands of years. Today, soy is added to a variety of processed foods and dietary supplements. The soy bean can be enjoyed raw or cooked to make a variety of dishes such as tempeh, miso or tofu. Research shows that soy and soy products offer certain benefits with few risks and side effects. Seek a health care provider before treating yourself with any soy products.
Cardiovascular Health Benefits
Soy and soy products can be beneficial for cardiovascular health and reduce the risk of coronary heart disease, according to a soy protein review published in the "Journal of Perinatal Education." The review reported that consumption of soy protein in place of animal protein is associated with lower LDL cholesterol, total cholesterol and triglyceride levels. Soy also contains naturally occurring phyto-estrogen compounds called isoflavones that may also promote cardiovascular health. The review concluded that 25 g of soy protein or one to two cups of soy milk per day can be part of a healthy diet.
Menopause Symptoms
The phytoestrogens present in soy may be beneficial for women due to their similarity to the female hormone estrogen, according to the National Center for Complementary and Alternative Medicine. Post-menopausal women have reported reduced menopause symptoms associated with soy supplements, the NCCAM reports. The soy protein review published in the "Journal of Perinatal Education" also reported that soy protein reduces the risk of osteoporosis in post-menopausal women by supporting healthy bone and calcium balance. However, more conclusive research is needed before recommending soy products for the treatment of menopause symptoms.
Complete Protein
Soy beans and products such as soy milk, tofu and tempeh provide a quality source of protein. Soybeans contain all nine essential amino acids that cannot be manufactured by the body. Therefore soybeans are considered a complete protein source similar to meat, fish and poultry, according to Medline Plus.
Allergy Risks
Soy allergies are one of the most common allergies that occur in children, reports the MayoClinic.com. Individuals suffering from an allergic reaction may experience symptoms of hives, dizziness, swelling of the face and tingling of the mouth. Family history of fever, asthma or eczema and allergies to other foods increases your risk for developing soy allergy, according to the MayoClinic.com. Consult a health care provider to determine if you're allergic to soy and if you should avoid all products that contain soy.
Side Effects
Soy and soy supplements are considered safe when taken for a short time, reports the NCCAM. Currently, the safety and effectiveness of long term soy use remains unknown. The NCCAM reports that soy consumption may cause nausea, bloating, constipation and similar stomach problems.
